Others

The Prostate: It is a gland that is part of the male reproductive system. It is approximately the size of a walnut and is located below the bladder and in front of the rectum. The urethra, the canal that carries urine from the bladder to the outside of the body, passes through the center of the prostate. The main function of the prostate is to produce a fluid that nourishes and transports sperm, making up part of the semen.

Benign Prostatic Hyperplasia (BPH):

• Definition: HBP is characterized by a benign (non-cancerous) enlargement of the prostate. This “hyperplasia” indicates an increase in the number of normal cells within the prostate gland.
• Symptom Mechanism: The prostate gland’s enlargement characteristic of BPH can compress the urethra, which runs through it. This obstruction makes urination difficult, leading to a collection of symptoms known as Lower Urinary Tract Symptoms (LUTS).
• Important Distinction from Cancer: It is essential to understand that BPH is not prostate cancer and does not increase a man’s risk of developing it. Although a man can have both BPH and prostate cancer simultaneously, and both can cause similar urinary symptoms, a complete urological evaluation is necessary to accurately diagnose the cause.

Storage Symptoms (or Irritants): Related to the bladder’s difficulty in storing urine normally.
• Increased Urinary Frequency (Pollakiuria): Frequent urination during the day.
• Urinary Urgency: A sudden, intense, and difficult-to-postpone urge to urinate.
• Nocturia: The need to wake up one or more times during the night to urinate (one of the most bothersome symptoms).
• Urge Urinary Incontinence: Involuntary loss of urine that occurs after a strong feeling of urgency (less common, but can happen).

Symptoms of Emptying (or Obstructions): Related to difficulty in expelling urine from the bladder.
• Hesitation: Difficulty or delay in starting urination, even when feeling the urge.
• Weak or Decreased Urinary Stream: The force or caliber of the urine stream is noticeably reduced.
• Intermittent: The urine stream stops and restarts one or more times during urination.
• Straining to urinate (pulling): The need to strain the abdominal muscles to start or maintain urination.
• Prolonged urination: Taking considerably longer than normal to empty the bladder.
• Terminal Drip: Slow flow of urine drops at the end of urination.

Post-Mincture Symptoms: They occur after you have finished urinating.
• Sensation of Incomplete Bladder Emptying: Feeling like there is still urine left in the bladder, even after urinating.
• Post-Micturition Drip: Involuntary loss of a few drops of urine shortly after finishing urinating, and sometimes even after getting dressed.

Detailed Medical History: The diagnostic process involves the doctor inquiring about your urinary symptoms—frequently utilizing the IPSS (International Prostate Symptom Score) to evaluate severity and impact on quality of life—in addition to taking a comprehensive medical history, including past surgeries, current medications, and lifestyle choices. A Voiding Diary may also be requested.

Physical examination: This procedure involves the physician manually examining the prostate gland via the rectum to assess its approximate dimensions, texture, and the presence of any suspicious nodules or areas of induration that might indicate malignancy.

Urine Analysis (Type II / Urine 2 and Urine Culture): To detect signs of infection, blood (hematuria), sugar, or other abnormalities.

PSA (Prostate-Specific Antigen): A blood test that measures PSA levels. PSA can be elevated in BPH, prostatitis (inflammation of the prostate), and prostate cancer. It is not a diagnostic test for cancer, but it helps assess risk and decide on the need for further investigations (such as a prostate biopsy). The PSA value can also influence the choice of treatment for BPH (e.g., 5-alpha-reductase inhibitors are more effective in men with higher PSA, which usually corresponds to larger prostates).

Post-void residual (PMR) measurement: It measures the amount of urine that remains in the bladder after urination. It can be done by ultrasound. A high RPM suggests ineffective bladder emptying.

Urofluxometry: A simple test that measures the speed and pattern of urine flow. A low maximum flow rate (Qmax) or a flattened flow pattern may indicate obstruction.

Ultrasound (Ultrasonography) of the Urinary Tract: It allows visualization of the kidneys (to check for dilation – hydronephrosis, which can be a sign of severe and prolonged obstruction), the bladder (to assess the thickness of its wall, the presence of stones or diverticula, and to measure the prostatic hyperplasia rate), and the prostate (to accurately estimate its volume and configuration, for example, if there is a prominent middle lobe). It can be performed suprapubically (externally) or transrectally.

Optional / Selected Cases:

• Cystoscopy: Endoscopic visualization of the urethra and bladder. This can be useful if there is hematuria, suspected urethral stricture, or before certain surgical procedures to assess anatomy.
• Complete Urodynamic Study: More specialized tests are needed to assess bladder function and confirm the presence of prostatic obstruction, especially if the diagnosis is uncertain, if bladder dysfunction is suspected (e.g., coexisting overactive or underactive bladder), or before considering surgery in more complex cases or after failure of previous treatments.

Acute Urinary Retention (AUR): Sudden and painful inability to urinate, requiring urgent bladder catheterization to empty the bladder.

Chronic Urinary Retention: Progressive incomplete bladder emptying, with high residual volumes, often without the patient realizing the severity.

Recurrent Urinary Tract Infections (UTIs): Urine trapped in the bladder can facilitate the growth of bacteria.

Formation of Bladder Stones: Due to urine stasis.

Recurrent Hematuria (Blood in the Urine): Caused by congestion of the blood vessels in an enlarged prostate.

Bladder Damage: The bladder can become thicker and more muscular (trabeculated) due to the effort to overcome the obstruction, diverticula (sacs in the bladder wall) can form, and in the long term, the bladder can lose its ability to contract effectively (stress bladder or hypoactive bladder).

Kidney Damage: In cases of chronic and severe obstruction, the pressure can be transmitted to the ureters and kidneys, causing dilation (hydroureteronephrosis) and eventually kidney failure. This is a rare but serious complication.

Active Surveillance (“Watchful Waiting”) and Lifestyle Modifications:

• Recommended for men with mild symptoms that do not significantly bother them.
• Modifications:
  • Liquid Management: Adjust the amount and timing of fluid intake.
  • Reduction of Bladder Irritants: Reduce caffeine, alcohol, etc.
  • Bladder Training Techniques and Scheduled Voiding.
  • Preventing or Treating Constipation.
  • Medication Review: Assess whether other medications may be worsening the LUTS

Pharmacological Treatment (Medications):

• Alpha-blockers (e.g., tamsulosin, alfuzosin, silodosin): They relax the muscles of the prostate and bladder neck, improving blood flow.
• 5-alpha-reductase inhibitors (5-ARIs) (e.g., finasteride, dutasteride): They reduce prostate size in the long term.
• Combination Therapy (Alphablocker + 5-ARI): Often more effective for moderate/severe symptoms and large prostates..
• Phosphodiesterase type 5 (PDE5-I) inhibitors (e.g., tadalafil 5 mg daily): For LUTS/BPH and erectile dysfunction.

Surgical Treatments (More invasive, but generally more definitive and long-lasting):

• Bipolar Transurethral Resection of the Prostate (TURP: Removal (“scraping”) of obstructive prostatic tissue through the urethra, using bipolar coagulation energy.
• Transurethral Incision of the Prostate (TUIP): Incisions in the bladder neck and prostate to widen the duct (for small prostates).
• Laser Therapies:
  • HoLEP (Holmium Laser Enucleation of the Prostate):
    Enucleation of the adenoma, effective for any size prostate.
  • PVP (Selective Photovaporization of the Prostate with GreenLight Laser): Steaming the fabric.
  • ThuLEP/ThuVEP (Thulium Laser Enucleation/Vaporization).
• Simple Prostatectomy (Adenomectomy) – for Very Large Prostates (>80-100g):
  • Robotic Simple Prostatectomy (Robot-Assisted): Minimally invasive removal of prostatic adenoma through small abdominal incisions. Combines the effectiveness of open surgery with faster recovery, less pain, and less blood loss..
  • Open Simple Prostatectomy: The traditional approach with an abdominal incision is increasingly reserved for when robotics is not available or in very specific cases.

Alternative Surgical Therapies:

• Less invasive options, on an outpatient basis or with a short stay.
• Rezum (Thermal Therapy with Water Vapor).
• UroLift (Prostate Urethral Lift System).
• iTind (Dispositivo Prostático Implantado Temporariamente).
• Aquablation (Image-guided water jet therapy).

It is crucial to emphasize that BPH is a benign condition and it does not turn into prostate cancer.

However, a man can have BPH and prostate cancer at the same time, and the symptoms may be similar.

Urological evaluation, including digital rectal examination and PSA testing, helps to detect prostate cancer early

Prostate tissue removed during surgeries for BPH (especially HoLEP or simple prostatectomy) is always sent for histopathological analysis to check for the presence of incidental cancer (cancer discovered “by chance”).

Urinary symptoms begin to interfere with your quality of life.

If you experience a sudden inability to urinate.

If you wish to discuss prostate cancer screening options or have concerns about your prostate health.

Benign prostatic hyperplasia (BPH) is a very common condition with aging men, but it doesn’t have to be a source of suffering or limitation. There are numerous effective treatment options that can alleviate its symptoms and dramatically improve your quality of life. Most importantly, don’t ignore the symptoms and seek specialized medical advice.

If urinary symptoms are affecting your daily life, or if you have any concerns about your prostate health, the first step is to schedule an appointment with a urologist. A thorough evaluation will allow for an accurate diagnosis and the development of a personalized treatment plan, which can range from simple lifestyle modifications to more advanced surgical procedures, such as robotic simple prostatectomy for large prostates.

We’re here to help you find the best solution for you. Schedule a consultation for a detailed assessment.

Definitio: LUTS is a broad term used to describe a group of symptoms related to problems with urine storage or elimination. These involve the functioning of the bladder, prostate (in men), and urethra.

Prevalence: They are extremely common, affecting a large percentage of men, with their frequency increasing with age. However, they should not be considered an inevitable part of aging.

Impact: LUTS can range from mild to severe and can have a significant impact on quality of life, affecting sleep, daily activities, social life, and overall well-being.

Brief Anatomy of the Male Lower Urinary Tract:

• Bladder: A muscular organ that stores urine produced by the kidneys.
• Prostate: A gland about the size of a walnut, exclusive to males, located below the bladder and in front of the rectum. The urethra (the canal that carries urine out of the body) passes through the center of the prostate. The prostate produces some of the fluid that makes up semen.
• Urethra: The tube that carries urine from the bladder out of the body.

Storage Symptoms (or Irritants):
Related to how the bladder stores urine.

• Increased Urinary Frequency (Pollakiuria): The need to urinate more often than usual during the day.
• Urinary Urgency: A sudden, intense, and difficult-to-postpone urge to urinate.
• Nocturia: The need to wake up one or more times during the night to urinate.
• Urge Urinary Incontinence: Involuntary loss of urine that occurs immediately after or during a feeling of urgency.

Symptoms of Emptying (or Obstructions): Related to difficulties during urination.

• Hesitation: Difficulty or delay in starting urination, even when the urge is felt.
• Weak or Decreased Urinary Stream: The force or caliber of the urine stream is reduced.
• Intermittent: The urine stream stops and restarts one or more times during urination.
• Straining to urinate (pulling): The need to strain the abdominal muscles to start or maintain urination.
• Prolonged urination: Taking considerably longer than normal to empty the bladder.
• Terminal Drip: Slow flow of urine drops at the end of urination, after the main stream has ceased

Post-Mincture Symptoms: They occur after you have finished urinating.

• Sensation of Incomplete Bladder Emptying: Feeling like there is still urine left in the bladder, even after urinating.
• Post-Micturition Drip: Involuntary loss of a few drops of urine shortly after finishing urinating, and sometimes even after getting dressed.

Benign Prostatic Hyperplasia (BPH): It is a non-cancerous enlargement of the prostate gland. As the prostate grows, it can compress the urethra, making it difficult to pass urine and causing primarily symptoms of urinary retention, but also of urinary retention. It is the most common cause of LUTS (Lumbar Urethral Syndrome) in men over 50.

Overactive Bladder (OAB): A condition in which the bladder muscle (detrusor) contracts involuntarily and frequently during the filling phase, leading to storage symptoms such as urgency, frequency, and nocturia, with or without urge incontinence. It can occur alone or in conjunction with BPH (benign prostatic hyperplasia).

Urinary Tract Infections (UTIs) or Prostatitis: Inflammation or infection of the bladder (cystitis), urethra (urethritis), or prostate (prostatitis) can cause acute irritative symptoms (painful urination, frequency, urgency) and sometimes obstructive symptoms.

Urethral Stricture: A narrowing of the urethral canal, usually due to scar tissue formed after infections (e.g., urethritis), trauma, previous urethral instrumentation, or surgery.

Bladder neck contracture: A narrowing of the bladder opening into the urethra (bladder neck). It can be a consequence of prostate surgery or occur without apparent cause (idiopathic).

Bladder Stones (Vesical Lithiasis): Stones that form or migrate to the bladder can cause irritation, pain, blood in the urine, and obstruction.

Bladder cancer or prostate cancer: Although less common as an initial cause of LUTS, these serious conditions should be considered and ruled out, especially if there are symptoms such as blood in the urine, bone pain, or unexplained weight loss.

Neurogenic Bladder: Problems with nerve control of the bladder due to neurological diseases such as diabetes mellitus (diabetic neuropathy), Parkinson’s disease, multiple sclerosis, spinal cord injuries, or stroke.

Detrusor Hypocontractility (Hypoactive or “Lazy” Bladder): A condition in which the bladder muscle is weak and does not contract strongly enough to effectively empty urine, leading to symptoms of incontinence and a high post-void residual volume.

Lifestyle Factors and Medications: Excessive fluid intake (especially at night), consumption of caffeine, alcohol or carbonated drinks, and certain medications (such as diuretics, nasal decongestants, some antidepressants and antihistamines) can cause or worsen LUTS.

Nocturnal Polyuria: Excessive urine production during the night, being a significant cause of nocturia. It may be related to fluid intake at night, sleep apnea, heart failure, or other medical conditions.

Detailed Medical History: The doctor will ask about:

• Standardized tools, such as the International Prostate Symptom Score (IPSS), are commonly employed to assess the severity of urinary symptoms and track treatment effectiveness. This evaluation covers the symptoms’ specific types, how long they last, and their frequency, intensity, and effect on a patient’s quality of life.
• Past medical history (other illnesses, surgeries, injuries).
• Usual medication.
• Lifestyle habits (fluid intake, diet type, caffeine and alcohol consumption, smoking). A Voiding Diary is often a helpful tool. For a period of several days, the patient should record:
• The times and volumes of fluid consumed.
• The times and volumes of urine passed.
• Any episodes of LUTS (Lower Urinary Tract Symptoms).

Physical examination: The abdominal examination is included, with the Digital Rectal Examination (DR) being a vital component. The rectal exam enables the physician to feel the prostate through the rectal wall to evaluate its size, shape, consistency, and check for any suspicious areas or nodules.

Urine Analysis (Type II / Urine 2 and Urine Culture): To detect the presence of infection, blood (hematuria), sugar (glucose), or other abnormal findings.

PSA (Prostate-Specific Antigen): A blood test that measures levels of PSA, a protein produced by the prostate. Elevated PSA levels may be associated with prostate cancer, but can also be caused by BPH, prostatitis, urinary tract infection, or recent manipulation of the prostate (such as a digital rectal exam or cystoscopy). It is an important test in the context of LUTS evaluation in men over 45-50 years of age.

Post-void residual (PMR) measurement: It assesses the amount of urine that remains in the bladder immediately after urination. It can be measured non-invasively using a bladder ultrasound. A high RPM indicates incomplete bladder emptying, which can predispose to infections and other problems.

Uroflowmetry: A simple, non-invasive test that measures the rate (output) and pattern of urine flow during urination. A weak urine flow or an altered pattern may suggest an obstruction to the outflow of urine.

Ultrasound (Ultrasonography) of the Urinary Tract: It allows visualization of the kidneys (to rule out dilation – hydronephrosis), the bladder (to assess the thickness of its wall, the presence of stones or diverticula, and to measure the prostatic hyperplasia rate) and the prostate (to estimate its volume and configuration).

Cystoscopy: An endoscopic examination that allows the urologist to visualize the inside of the urethra and bladder using a thin instrument with a camera at the tip (cystoscope). It is indicated in cases of hematuria, suspected urethral stricture, bladder stones or tumors, or to assess the appearance of the prostate and bladder neck.

Complete Urodynamic Study: A set of more specialized tests that evaluate in detail the function of the bladder (storage and emptying) and urethra. They measure pressures, volumes, and flows. They are particularly important in cases of uncertain diagnosis, when there is suspicion of associated bladder dysfunction (e.g., overactive or underactive bladder), before considering surgery for BPH, or if previous treatments have not been successful.

Active Surveillance (“Watchful Waiting”) and Lifestyle Modifications:

• Recommended for men with mild symptoms that do not significantly bother them.

Modifications:

• Liquid Management: Adjust the amount and timing of fluid intake (avoid drinking large volumes at once, reduce fluid intake a few hours before bedtime or leaving home).
• Reduction of Bladder Irritants: Reduce your consumption of caffeine (coffee, black tea, some soft drinks), alcohol, carbonated beverages, and very spicy or acidic foods, which can worsen storage symptoms.
• Bladder Training Techniques: For men with symptoms of urgency, it may involve urinating at scheduled times and trying to gradually delay urination to increase bladder capacity
• Preventing or Treating Constipation: A diet rich in fiber and good hydration can help.
• Medication Review: Some medications for other conditions can worsen LUTS (e.g., diuretics, decongestants, some antidepressants). Your doctor can assess if there are alternatives.

Pharmacological Treatment (Medications):

• Alpha-Blockers (e.g., Tamsulosin, Alfuzosin, Silodosin, Doxazosin): These medications work by relaxing the smooth muscles in the prostate and bladder neck. This action reduces compression on the urethra, leading to an improvement in urinary flow. Their therapeutic effect is typically noticeable within a relatively short time frame (days to weeks). Potential side effects include dizziness, often due to postural hypotension (a drop in blood pressure upon standing), and in some cases, retrograde ejaculation (where semen enters the bladder instead of being expelled through the urethra during orgasm).
• 5-alpha-reductase inhibitors (5-ARIs) (e.g., finasteride, dutasteride): They work by blocking the enzyme that converts testosterone into dihydrotestosterone (DHT), the main hormone responsible for prostate growth. This leads to a gradual reduction in prostate size (it takes 3 to 6 months or more to have its maximum effect). They are most effective in men with larger prostates. They may lower PSA levels (which should be taken into account in prostate cancer screening) and, rarely, cause sexual side effects such as decreased libido or erectile dysfunction.
• Combination Therapy (Alphablocker + 5-ARI): The combination of these two types of medication is often more effective than using each one alone, especially in men with moderate to severe symptoms and an enlarged prostate. It helps relieve symptoms more quickly (due to the alpha-blocker) and reduce the risk of long-term BPH progression (due to 5-ARI), such as acute urinary retention or the need for surgery.
• Antimuscarinics / Beta-3 Adrenergic Agonists (e.g., solifenacin, tolterodine, mirabegron): If storage symptoms (urgency, frequency, nocturia) are predominant and bothersome, these medications (which relax the bladder) can be used, sometimes in combination with an alpha-blocker. They should be used with caution in men with suspected significant obstruction, as they may increase the risk of urinary retention.
• Phosphodiesterase type 5 (PDE5-I) inhibitors (e.g., tadalafil 5mg daily): Originally used for erectile dysfunction, daily tadalafil is also approved for the treatment of LUTS/BPH and may be a good option for men suffering from both conditions.

Minimally Invasive Surgical Therapies (MISTs):

• These are newer, less invasive options than traditional surgeries, generally performed on an outpatient basis or with a short hospital stay. They aim to relieve prostatic obstruction with a lower risk of side effects, including sexual ones.
• Rezum (Thermal Therapy with Water Vapor): It uses the energy of water vapor to destroy (ablate) excess prostate tissue.
• UroLift (Prostate Urethral Lift System): It involves the placement of small, permanent implants that separate the lateral prostate lobes, clearing the urethral canal.
• iTind (Temporarily Implanted Prostate Device): A device that is placed in the prostatic urethra for 5-7 days and, as it expands, remodels the tissue, creating channels to improve flow.

Surgical Treatments for BPH (More invasive, but generally with more definitive and lasting results)

• Indicated for men with moderate to severe symptoms that do not respond adequately to medication, or in the presence of BPH complications (such as recurrent urinary retention, recurrent urinary tract infections, bladder stones secondary to obstruction, persistent hematuria, or renal insufficiency).
• Transurethral Resection of the Prostate (TURP): Considered for many years the “gold standard” of surgery for BPH. The prostatic tissue causing the obstruction is removed (“scraped”) through the urethra using a special instrument called a resectoscope, which has a light source, a camera, and an electric loop to cut and coagulate the tissue.
• Transurethral Incision of the Prostate (TUIP): An option for men with smaller prostates. One or two incisions are made in the bladder neck and prostate to widen the urethral canal without removing tissue.
• Laser Therapies: There are several techniques that use laser energy to remove or vaporize obstructive prostate tissue. The most common include:
• HoLEP (Holmium Laser Enucleation of the Prostate): The LASER is used to “peel” (enucleate) the prostatic adenoma (the growing inner part of the prostate) from its outer capsule. The enucleated tissue is then fragmented inside the bladder (morcellated) and removed. It is a very effective technique for prostates of any size, including very large ones, and is associated with less blood loss, shorter catheterization time, and a lower long-term reintervention rate compared to TURP.
• PVP (Selective Photovaporization of the Prostate with GreenLight LASER): The LASER is used to vaporize prostate tissue, turning it into water vapor. It is a good option for small to moderately sized prostates, especially in patients taking anticoagulants.
• ThuLEP/ThuVEP (Thulium Laser Enucleation/Vaporization of the Prostate): Similar to HoLEP or PVP, but using a Thulium LASER.
• Simple Prostatectomy (Adenomectomy): It is the surgical removal of the inner part of the prostate (the adenoma) that causes the obstruction. It is reserved for men with very large prostates (generally > 80-100 grams), where transurethral techniques may be less effective, more time-consuming, or have a higher risk of complications. It can be performed by:
• Open Simple Prostatectomy: Through an incision in the lower abdomen. This is the traditional approach for very large prostates.
• Robotic Simple Prostatectomy (Robot-Assisted): This is a minimally invasive approach to performing adenomectomy on very large prostates. The surgeon uses a robotic platform to remove the prostatic adenoma through small incisions in the abdomen. This technique combines the effectiveness of open surgery with the benefits of minimally invasive surgery (less pain, less blood loss, faster recovery).

Treatment of Other Causes of LUTS

• Treatment will be directed to the specific cause identified: antibiotics for UTI or prostatitis; urethral dilation or urethroplasty (reconstructive surgery of the urethra) for strictures; specific medications, botulinum toxin, or neuromodulation for overactive bladder not related to prostatic obstruction; addressing the underlying cause in cases of neurogenic bladder, cancer, etc.

Acute urinary retention (sudden and painful inability to urinate, requiring urgent bladder catheterization).

Chronic urinary retention (progressive incomplete bladder emptying, with high residual volumes).

Recurrent urinary tract infections (UTIs).

Formation of bladder stones due to urine stasis.

Recurrent, sometimes significant, hematuria (blood in the urine).

Bladder damage: formation of diverticula (sacs in the bladder wall), thickening of the bladder muscle wall (trabeculation), and, in the long term, possible loss of its contractile capacity (stress bladder or hypoactive bladder).

Kidney damage (bilateral hydronephrosis, kidney failure) – this is a rare but serious complication that can occur in cases of untreated chronic and severe obstruction.

Lower Urinary Tract Symptoms (LUTS) are a frequent complaint among men, but they should not be seen as an inevitable part of the aging process nor a reason for resignation. A complete urological medical evaluation is essential to identify the cause of your symptoms and allow for the development of an individualized treatment plan. Currently, there is a wide range of effective therapeutic options, ranging from lifestyle modifications and medications to minimally invasive procedures and more advanced surgeries, such as those assisted by robotic technology, which can significantly improve your quality of life and prevent future complications.

If you are experiencing LUTS that are affecting your daily life, don’t hesitate to seek urological advice. An open and honest discussion about your symptoms and concerns is the first and most important step in finding the right solution for you.

Schedule a consultation for a complete evaluation so we can explore together the best treatment options for your specific case.

Definition: Overactive Bladder is a clinical syndrome characterized primarily by urinary urgency. This is usually accompanied by increased urinary frequency (needing to urinate many times during the day) and nocturia (the necessity of waking up one or more times during the night to void). These symptoms may manifest with or without urge urinary incontinence, which is the involuntary loss of urine that occurs immediately following or during a sudden sensation of urgency.
The Core Symptom: Urinary Urgency Urgency is the fundamental, defining feature of an Overactive Bladder. It is described as a sudden, intense, and compelling desire to urinate that is exceptionally difficult to delay or suppress.

“Wet” OAB vs. “Dry” OAB

• “Wet” OAB: This occurs when the sensation of urgency is accompanied by involuntary urine leakage (urge incontinence)
• “Dry” OAB: This occurs when the patient experiences urgency, high frequency, and nocturia, but does not suffer from urine leakage

Underlying Mechanism: It is generally understood that OAB results from inappropriate and involuntary contractions of the bladder muscle (the detrusor muscle) during the filling phase. Under normal conditions, the bladder should remain relaxed while storing urine; however, in OAB, these untimely contractions create the sudden, pressing sensation of urgency.

Aging: Natural, age-related physiological changes in the nerves and muscles of the bladder and the pelvic floor.

Neurological Conditions: Disorders that affect the brain, spinal cord, or the nerves regulating the bladder can trigger OAB. Examples include:

• Parkinson’s disease.
• Multiple Sclerosis (MS).
• Stroke (Cerebrovascular Accident).
• Spinal cord injuries.
• Diabetes Mellitus (due to diabetic neuropathy, which damages the bladder’s nerve signals).

Bladder Outlet Obstruction (Primarily in Men): Benign Prostatic Hyperplasia (BPH) causes chronic obstruction of urinary flow, which can lead to secondary changes in the bladder wall and result in OAB symptoms.

Urinary Tract Infections (UTIs): An active infection can cause temporary OAB symptoms, such as sudden urgency and high frequency.

Bladder Stones or Tumors: The presence of foreign bodies or growths within the bladder can irritate the bladder lining and trigger overactive contractions.

Consumption of Bladder Irritants: Certain dietary choices can worsen symptoms in sensitive patients. Common irritants include caffeine (coffee, tea, soft drinks, chocolate), alcohol, carbonated beverages, and highly acidic or spicy foods (such as citrus fruits).

Fluid Intake Imbalance: Consuming excessive fluids can increase urinary frequency, while drinking too little can lead to highly concentrated urine that irritates the bladder lining.

Specific Medications: Certain drugs, such as diuretics (water pills), can significantly increase urine production and the frequency of voiding.

Chronic Constipation: An overfilled bowel can exert physical pressure on the bladder, aggravating symptoms.

Previous Pelvic Procedures: Past pelvic surgeries or radiotherapy can sometimes impact the nerves or the structural integrity of the bladder.

Weakness of the Pelvic Floor Muscles: While primarily linked to stress incontinence, a weakened pelvic floor may be less effective at helping the brain suppress involuntary bladder contractions.

Urinary Urgency: The hallmark symptom—a sudden, powerful, and overwhelming urge to urinate that is nearly impossible to ignore.

Increased Urinary Frequency: Needing to void more often than what is considered normal for your routine. Generally, this is defined as urinating more than 8 times in a 24-hour period, though this varies by individual.

Nocturia: The need to interrupt sleep one or more times per night to urinate. This is often the most disruptive symptom regarding overall quality of life.

Urge Urinary Incontinence (Optional): Involuntary leakage that happens immediately after a strong urge. While not everyone with OAB has this “wet” component, it can be extremely limiting for those who do.

Constant anxiety regarding the proximity of a restroom (“toilet mapping”).

Withdrawal from social activities, travel, and exercise.

Chronic sleep deprivation and daytime exhaustion.

Social isolation and increased risk of depression.

Skin irritation or hygiene concerns due to incontinence.

Detailed Medical History: Your doctor will discuss the exact nature of your symptoms (urgency, frequency, nocturia, and leakage), their duration, and their severity. Validated questionnaires (like the OAB-q or ICUD-OAB) may be used to provide an objective score.

Voiding Diary: This is a vital diagnostic tool. You will be asked to record your habits for 2 to 3 days, including: types and volumes of liquids consumed; volumes of urine produced (using a measuring container); and the timing and intensity of urgency or leakage episodes. This helps identify objective patterns in your bladder behavior.

Physical Examination: This may include an abdominal exam, a pelvic exam (in women) to check for prolapse or pelvic floor strength, or a digital rectal exam (in men) to evaluate the prostate.

Urinalysis and Culture: Essential to rule out infection, blood (hematuria), or glucose in the urine, which could point to other medical issues.

Post-Void Residual (PVR) Measurement: Performed via ultrasound, this test measures how much urine remains in the bladder after you urinate. It ensures the bladder is emptying correctly, as incomplete emptying can mimic OAB or contraindicate certain treatments.

Optional/Specialized Tests:

Urinary Tract Ultrasound: To visualize the kidneys and bladder and, in men, estimate the size of the prostate.

Urodynamic Study: Specialized tests that measure pressures and volumes within the bladder during filling and emptying. These can confirm “detrusor overactivity” and help distinguish OAB from other forms of bladder dysfunction.

Cystoscopy: An endoscopic look inside the bladder, performed if there are atypical symptoms like blood in the urine or significant pain, to rule out stones or tumors.

Behavioral Therapies (First-Line Treatment):

Lifestyle Modifications:
• Fluid Management: Learning to balance intake—avoiding “chugging” large volumes and reducing fluids in the evening to combat nocturia.
• Dietary Adjustments: Identifying and limiting bladder irritants like caffeine, alcohol, and carbonated drinks.
• Weight Management: Reducing weight if overweight to decrease pressure on the bladder.
• Managing Constipation: Utilizing high-fiber diets and hydration to ensure regular bowel movements.
• Bladder Retraining: Establishing a timed voiding schedule and gradually increasing the time between trips to the bathroom to increase bladder capacity.
• Pelvic Floor Muscle Training (Kegels): Strengthening the muscles that assist in suppressing urgency and preventing leakage.

Pharmacological Treatment (Second-Line Treatment): If behavioral changes are insufficient, medication may be added:

• Antimuscarinics/Anticholinergics (e.g., oxybutynin, solifenacin, tolterodine): These block the receptors that trigger bladder contractions, helping the detrusor muscle relax. Common side effects can include dry mouth, constipation, and blurred vision.
• Beta-3 Adrenergic Agonists (e.g., mirabegron, vibegron): These also promote bladder relaxation but via a different pathway. They typically have fewer side effects like dry mouth but may require blood pressure monitoring.
• Vaginal Estrogen: For postmenopausal women, local estrogen can improve the health of the tissues around the urethra and bladder, reducing urgency

Advanced Therapies (Third-Line Treatment for Refractory Cases):

• Botulinum Toxin (Botox®) Injections: Using a cystoscope, Botox is injected into the bladder muscle to cause prolonged relaxation. Effects typically last 6–12 months. A small risk involves temporary urinary retention, which may require short-term self-catheterization.
• Neuromodulation (Nerve Stimulation):
  • Sacral Neuromodulation (SNM): Often called the “Bladder Pacemaker,” this involves a small device implanted under the skin that sends electrical pulses to the sacral nerves to restore normal bladder signals.
  • Percutaneous Tibial Nerve Stimulation (PTNS): A less invasive method using a fine needle at the ankle to send signals to the nerves controlling the bladder via the tibial nerve.

Surgery (Rarely Indicated):

• Augmentation Cystoplasty: Increasing bladder capacity using a piece of the patient’s own bowel; reserved for extreme, complex cases.
• Urinary Diversion: A final resort for intolerable symptoms where all other treatments have failed.

Adherence: Stay consistent with your behavioral exercises and medications; results often take time.

Patience: Finding the right combination of treatments is often a process of trial and error.

Open Communication: Keep your medical team informed about what is working and any side effects you experience.

Proactive Planning: Mapping out restrooms in new locations can significantly lower anxiety.

Clothing Choices: Opt for clothes that are easy to remove quickly during an urgent moment.

Discreet Support: Use absorbent products if necessary to maintain your confidence while you work through your treatment plan.

Emotional Support: If OAB is impacting your mental health, seek counseling or join a support group. You are not alone in this journey.

Overactive bladder syndrome is a chronic condition, but its symptoms can be significantly relieved and controlled with proper treatment. You don’t have to let your bladder dictate the rules of your life. The first and most important step is to seek medical help and openly discuss your symptoms.

If you suffer from frequent urinary urgency, needing to go to the bathroom many times during the day or night, or if you have urine leakage associated with a sudden urge, know that you are not alone and that there are many effective treatment options available.

Schedule a consultation for a complete and personalized evaluation. Together, we can identify the best treatment strategy for your case, with the goal of reducing your symptoms, regaining bladder control, and improving your quality of life.

Relevant Anatomy:

• Kidneys: Two bean-shaped organs in the back of the abdomen responsible for filtering blood, removing waste, and producing urine.
• Renal Pelvis: The central, funnel-shaped part of the kidney that collects urine before it enters the ureter.
• Ureter: A thin, muscular tube that carries urine from the renal pelvis of each kidney to the bladder.
• Pyeloureteral Junction (PUJ/UPJ): The specific point where the renal pelvis narrows and joins the ureter.

PUJ Syndrome (UPJ Obstruction): This syndrome occurs when a narrowing or blockage at this junction (UPJ) hinders the normal flow of urine from the kidney to the ureter. Consequently, urine accumulates in the renal pelvis, causing the kidney to dilate. This pathological dilation is known as hydronephrosis.

For Infants and Young Children:

• Hydronephrosis: Frequently detected on prenatal ultrasound scans.
• Palpable Mass: After birth, it may manifest as a palpable abdominal mass
• Urinary Tract Infections (UTIs): Often accompanied by fever.
• Systemic Signs: Vomiting, feeding difficulties, or poor weight gain

In Older Children and Adults:

• Flank Pain: A dull, persistent, or sharp (colicky) pain in the side or back below the ribs
• Dietl’s Crisis: Intense episodes of flank pain, nausea, and vomiting triggered by high fluid intake (e.g., alcohol or caffeine), which increases urine production and pressure
• Hematuria: Blood in the urine, often occurring after physical exercise or minor trauma.
• Kidney Stones: Formed due to urine stasis (stagnation)
• Hypertension: High blood pressure can occasionally result from chronic obstruction.

Renal Ultrasound: Usually the first test to visualize hydronephrosis and assess kidney tissue thickness.

Diuretic Renal Scintigraphy (Renogram – MAG3/DTPA): A crucial test to confirm obstruction and assess the function of each kidney. A diuretic (furosemide) is given to stimulate flow; if the kidney is obstructed, the tracer clears very slowly.

Uro-CT or Uro-MRI: Provides detailed anatomical images to identify the exact location of the narrowing and check for crossing vessels.

Retrograde Pyelography: An invasive test where contrast is injected directly into the urinary system to delineate the anatomy, often performed during surgical planning.

Progressive worsening of hydronephrosis.

Irreversible loss of kidney function due to continuous pressure thinning the renal tissue.

Recurrent kidney infections (pyelonephritis).

Secondary high blood pressure and chronic pain.

Observation and Monitoring:

Indicated for mild to moderate cases, especially in infants where the condition might resolve spontaneously. This requires regular follow-up with ultrasounds and renograms.

Surgical Intervention (Pyeloplasty):

Pyeloplasty is the “gold standard” curative treatment.

• Technique: The Anderson-Hynes dismembered pyeloplasty involves removing the narrowed segment and reconstructing the connection (anastomosis) between the renal pelvis and the ureter.
• Robotic Pyeloplasty: This is the preferred minimally invasive approach. The surgeon uses robotic arms with high-precision instruments and 3D vision.
• Advantages: Smaller incisions, less pain, faster recovery, and very high success rates (above 95%) comparable to or higher than open surgery.

Endoscopic Treatment (Endopyelotomy):
The narrowing is incised from within the urinary tract using a laser or cold knife. It has lower success rates than pyeloplasty and is generally reserved for specific secondary cases.

Double J Stent: A temporary internal catheter is usually placed to keep the new junction open during healing. It is typically removed a few weeks later via a simple cystoscopy.

Surgical Drain: A small drain may be left for a few days to remove fluid.

Follow-up: Periodic imaging (ultrasound or scintigraphy) is required to ensure the obstruction is resolved and kidney drainage has improved.

The prognosis after surgical correction of UPJ obstruction is generally very good. Pyeloplasty (especially robotic or laparoscopic) has high success rates in resolving the obstruction and relieving symptoms (above 90-95%).

Recovery of kidney function depends on the degree of kidney impairment present before surgery. In many cases, kidney function can improve or at least stabilize, preventing further deterioration.

Long-term urological follow-up is important to monitor kidney function and ensure that there is no recurrence of the obstruction (which is rare).

Pyeloureteral junction syndrome is a condition that, although it can be congenital or acquired, has effective treatment. If left untreated, it can lead to serious complications, including chronic pain, infections, and loss of kidney function. Early diagnosis and appropriate treatment, often through minimally invasive surgery such as robotic pyeloplasty, are crucial to preserving kidney health and ensuring a good quality of life.

If you or your child have been diagnosed with UPJ obstruction, or if you are experiencing symptoms that may suggest this condition, it is essential to seek evaluation by a urologist experienced in this area. We have the knowledge, experience, and state-of-the-art technology, including robotic pyeloplasty, to offer accurate diagnosis and effective, personalized treatment.

Schedule a consultation so we can discuss your case in detail and determine the best treatment approach.

Definition: Hematuria literally means the presence of red blood cells (blood) in the urine.

Types of Hematuria: Hematuria can present in two main forms:

• Macroscopic (or Visible) Hematuria: Blood is visible to the naked eye, changing the color of the urine to pink, bright red, wine-colored, or brownish (similar to “tea” or “cola”). Sometimes, small blood clots may be visible.
• Microscopic (or Non-Visible/Hidden) Hematuria: The amount of blood in the urine is so small that it does not alter its visible color. The presence of red blood cells is detected only through laboratory analysis of the urine under a microscope or with the use of reagent strips (test strip) in a routine urine test.

Importance: Regardless of whether it is macroscopic or microscopic, visible only once or persistently, hematuria requires medical investigation to determine its cause.

Common Urological Causes

• Urinary Tract Infections (UTIs): Such as cystitis (bladder infection), pyelonephritis (kidney infection), urethritis (urethral infection), or prostatitis (inflammation/infection of the prostate in men). Frequently, hematuria in these cases is accompanied by other symptoms such as pain or burning during urination (dysuria), increased urinary frequency, urinary urgency, and sometimes fever.
• Urinary Lithiasis (Kidney, Ureter, or Bladder Stones): Kidney stones can cause irritation and minor damage to the lining of the urinary tract as they move or rub against it, leading to bleeding. Hematuria may be associated with severe pain (renal colic).
• Benign Prostatic Hyperplasia (BPH): In older men, benign prostatic hyperplasia (BPH) can lead to bleeding, especially from small superficial blood vessels in the prostate.
• Trauma: An injury to the kidneys, bladder, or urethra due to an accident, fall, or direct blow to the abdominal or lumbar region
• Intense Physical Exercise: Known as “runner’s hematuria” or exercise-induced hematuria, it is a rare, usually microscopic and transient cause that can occur after very intense physical exertion. It is a diagnosis of exclusion, meaning that all other causes must be ruled out first.

Serious Urological Causes (which should always be ruled out):

• Urinary Tract Cancer: Hematuria, especially macroscopic and painless hematuria, can be the first sign of cancer. Types include:
• Bladder Cancer: It is one of the most important causes of hematuria, particularly in older people and smokers.
• Kidney Cancer (Renal Cell Carcinoma).
• High urothelial cancer (affecting the renal pelvis or ureter).
• Prostate cancer (in men): Although it less frequently causes hematuria as an initial symptom, it can occur in more advanced stages or in more aggressive tumors.
• Urethral cancer (very rare).

Nephrological Causes (Kidney Medical Problems – Glomerular Diseases):

• In these cases, the bleeding originates in the small filters of the kidneys (the glomeruli). Examples include:
• Glomerulonefrites: A group of diseases that cause inflammation of the glomeruli, such as IgA nephropathy (Berger’s disease), lupus nephritis (in patients with systemic lupus erythematosus), Alport syndrome (a hereditary disease), or post-infectious glomerulonephritis (which can occur after certain infections, such as tonsillitis).
• In these situations, the urine may have a more “brownish” or “cola-colored” appearance, and there may be other signs such as swelling (edema), high blood pressure (hypertension), or protein loss in the urine (proteinuria). These cases generally require evaluation by a nephrologist.

Other Possible Causes

• Medications: Some medications can cause hematuria, such as anticoagulants (e.g., warfarin, heparin, newer oral anticoagulants), antiplatelet agents (e.g., aspirin, clopidogrel), cyclophosphamide (used in chemotherapy), and, rarely, certain penicillins.
• Hematological Diseases (Blood Diseases): Coagulation disorders such as hemophilia or von Willebrand disease, or conditions such as thrombocytopenia (low platelet count) or sickle cell anemia
• Renal Vascular Malformations: Abnormalities in the blood vessels of the kidney.
• Urinary Tract Endometriosis (in women): Presence of endometrial tissue in the urinary tract, which may bleed cyclically, in sync with menstruation.
• Radiation-induced cystitis or chemotherapy-induced hemorrhagic cystitis: Bladder inflammation and bleeding as a side effect of cancer treatments.

Pseudohematuria (False Hematuria): It is important to note that sometimes urine can take on a reddish color due to substances other than blood. This can happen after consuming certain foods (such as beets, blackberries, rhubarb) or due to some medications (e.g., rifampicin, phenytoin, phenolphthalein laxatives). Urinalysis easily distinguishes pseudohematuria from true hematuria.

Pain

• Colicky pain in the flank or lower back that radiates to the groin: This suggests a kidney or ureteral stone, or the passage of clots obstructing the ureter.
• Pain in the suprapubic region (lower abdomen): This could indicate a bladder infection (cystitis) or a bladder stone.
• Pain or burning sensation when urinating (dysuria): Often associated with urinary tract infections, urethral stones, or inflammation.

Irritative Urinary Symptoms

• Increased urinary frequency (pollakiuria).
• Urinary urgency (sudden and strong urge to urinate).
• These symptoms may suggest a urinary tract infection, bladder cancer, or, in men, BPH (benign prostatic hyperplasia).

Obstructive Urinary Symptoms (Primarily in Men)

• Weak or interrupted urine stream, hesitancy to start urination, straining to urinate.
• These symptoms may suggest BPH or a urethral stricture (narrowing).

Fever, chills: Strongly suggestive of a urinary tract infection, such as acute cystitis or, more seriously, pyelonephritis (kidney infection).

Unexplained Weight Loss, Extreme Fatigue, Night Sweats: These may be warning signs of a neoplasm (cancer).

Swelling (edema) in the legs or around the eyes, high blood pressure: They may suggest a nephrological cause (glomerular disease).

Presence of clots in urine: The shape of blood clots can provide clues about the origin of the bleeding. Long, thin (thread-like) clots often suggest an origin in the upper urinary tract (kidney or ureter), while more irregular and bulky clots may originate from the bladder.

Detailed Medical History: The doctor will ask about the characteristics of the hematuria (when it started, whether it is constant or intermittent, whether there are clots), associated symptoms, past medical history (other illnesses, surgeries, usual medications – especially anticoagulants or antiplatelet drugs), family history (urological cancer, hereditary kidney diseases) and lifestyle habits (smoking, occupational exposure to chemicals).

Physical examination: A general examination, including blood pressure measurement, abdominal palpation and, if indicated, digital rectal examination (in men to assess the prostate) or gynecological examination (in women, to rule out gynecological causes of bleeding that may be confused with hematuria).

Urine Analysis (Type II / Urine 2 and Urinary Sediment): It confirms the presence of red blood cells, assesses their morphology (the presence of dysmorphic red blood cells or red blood cell casts suggests a medical glomerular/renal origin), and searches for the presence of leukocytes (white blood cells, which indicate inflammation or infection), nitrites (a sign of bacterial infection), or crystals (which may indicate kidney stones).

Urine culture with antibiogram: If a urinary tract infection is suspected, the goal is to identify the causative bacteria and test for antibiotic sensitivity.

Urinary Cytology: This involves observing cells under a microscope that flake off from the lining of the urinary tract and are eliminated in the urine. It aims to identify malignant (cancerous) cells. It is most sensitive in detecting high-grade bladder or upper urothelial tumors. Several samples may be required.

Blood Tests:

• Kidney Function: Evaluation of urea and creatinine levels to check if the kidneys are functioning properly.
• Complete Blood Count: To assess for the presence of anemia (if bleeding is significant or chronic) and platelet count (important in coagulation).
• Coagulation studies (PT, aPTT, INR): Especially if the patient is taking anticoagulants or if a coagulation disorder is suspected.
• PSA (Prostate-Specific Antigen): In men, depending on age and clinical context, to aid in prostate cancer screening.

Imaging Tests of the Urinary Tract: They are essential for visualizing the organs and identifying the source of the bleeding.

• Renal and Bladder Ultrasound (Echocardiography): It is often one of the first tests performed, as it is non-invasive and does not use radiation. It can detect solid or cystic renal masses, dilation of the collecting system (hydronephrosis), bladder or kidney stones, and assess prostate size.
• Uro-Computed Tomography (Uro-CT or CT Urogram): It is considered the most detailed imaging examination and, in many cases, the “gold standard” for investigating hematuria, especially if there is suspicion of pathology of the upper urinary tract (kidneys, ureters) or to better characterize ultrasound findings. It allows the identification of tumors, calculi of all types, complex cysts, malformations, and other structural anomalies. It generally involves the administration of intravenous iodinated contrast.
• Magnetic Resonance Urography (MRU): It is an excellent alternative to CT urography in patients who have contraindications to the use of iodinated contrast (e.g., severe allergy) or who must avoid exposure to ionizing radiation (e.g., pregnant women, if absolutely necessary).

Cystoscopy

• It is a crucial and often indispensable endoscopic examination in the evaluation of hematuria, especially macroscopic or persistent microscopic hematuria in adults with risk factors.
• A thin, flexible (or rigid, depending on the situation) instrument with a video camera at the tip (cystoscope) is inserted through the urethra into the bladder.
• It allows for direct and detailed visualization of the inner lining of the urethra and bladder, enabling the identification of bladder tumors (even very small ones), areas of inflammation, stones, diverticula, or other possible sources of bleeding.
• If suspicious lesions are found during cystoscopy, biopsies (collecting small tissue samples for histopathological analysis) or even complete resection of small tumors may be performed.

Ureterorrenoscopy (URS): In selected cases, if imaging tests (such as CT urography) suggest the presence of a tumor or other lesion in the ureter or renal pelvis, this more invasive endoscopic examination may be necessary. A ureteroscope (thinner than a cystoscope) is passed through the bladder and up the ureter to the renal pelvis for direct visualization and, if necessary, collection of biopsies.

Nephrological Evaluation: If the initial investigation (especially urine characteristics and blood tests) suggests a glomerular cause (medical kidney disease), the patient should be referred to a nephrologist. The nephrologist may consider the need for a percutaneous renal biopsy to diagnose the specific glomerular disease.

Urinary Tract Infections (UTIs): Treatment with antibiotics.

Kidney or Ureteral Stones: Treatment of pain, expulsive medical therapy to facilitate the spontaneous passage of small stones, or procedures to remove or fragment the stone (such as Extracorporeal Shock Wave Lithotripsy – ESWL, Laser Ureterorenoscopy, or Percutaneous Nephrolithotomy – PNL).

Benign Prostatic Hyperplasia (BPH): Medication to relieve symptoms or reduce prostate size, or surgery to remove obstructive prostate tissue (e.g., TURP, HoLEP, Robotic Simplex Prostatectomy for very large prostates).

Cancer (Bladder, Kidney, Prostate, Upper Urothelium): Treatment will depend on the type of cancer, its stage (extent) and grade (aggressiveness), and may include surgery (often minimally invasive, such as robotic surgery), chemotherapy, radiation therapy, immunotherapy, or targeted therapy.

Glomerular (Nephrological) Diseases: Treatment is specific to each type of glomerulonephritis and may involve medications to control blood pressure, reduce protein loss in the urine, or immunosuppressants (for autoimmune diseases).

Drug-Induced Hematuria: Adjusting or discontinuing the offending medication should always be done under medical supervision, weighing the risks and benefits.

Seeing blood in your urine can understandably cause anxiety. However, the most important message to remember is: Do not ignore hematuria. Although many of its causes are benign, it is essential to carry out a thorough medical investigation to rule out more serious conditions and identify the exact source of the bleeding.

If you have noticed blood in your urine (even just once), or if a routine test has detected microscopic hematuria, the most important and correct step is to consult a urologist without delay. Timely evaluation allows for an accurate diagnosis and, if necessary, the initiation of appropriate treatment for the underlying cause, which is crucial for a good prognosis, especially in the case of more serious conditions.

Our team is here to help you clarify all your doubts and conduct the necessary research with the utmost rigor, using the most advanced experience and technology available. Schedule a consultation for a complete and personalized assessment.

The Urothelium: It is a type of specialized cellular tissue that lines the inside of much of the urinary tract. This lining begins in the renal pelvis (the part of the kidney that collects urine), continues through the ureters (the tubes that carry urine from the kidneys to the bladder), the bladder itself, and part of the urethra (the canal that carries urine out of the body). The urothelium has the particularity of being elastic and protecting the underlying tissues from contact with urine.

The Upper Urinary Tract: It refers specifically to renal pelvis and to ureters.

Neoplasia do Urotélio Alto (UTUC – Upper Tract Urothelial Carcinoma): It is a cancer that originates in the urothelial cells located in the renal pelvis or ureter. It is histologically similar to the most common type of bladder cancer (urothelial carcinoma of the bladder), since both develop from the same type of lining cells.

UTUC is considered a relatively rare cancer, representing only about 5% to 10% of all urothelial neoplasms. The vast majority of urothelial neoplasms occur in the bladder.

It can affect the upper urinary tract on one side (unilateral) or, very rarely, on both sides (bilateral).

Smoking: It is the most important and well-established risk factor, just as it is for bladder cancer. The carcinogenic substances in tobacco are filtered by the kidneys and concentrate in the urine, damaging the urothelium.

Exposure to Aristolochic Acid: Found in certain plants of the genusAristolochiaExposure to this compound is associated with “Balkan nephropathy” and an extremely high risk of developing UTUC.

Lynch syndrome (Hereditary Nonpolyposis Colorectal Cancer – HNPCC): It is a hereditary genetic condition that significantly increases the risk of developing several types of cancer, including UTUC and colorectal cancer.

Chronic Inflammation and Infections of the Upper Urinary Tract: Prolonged irritation of the urothelium, for example, due to kidney stones (lithiasis) or chronic infections, can predispose to malignant cellular changes.

Occupational Exposure to Certain Chemical Substances: Workers in the paint, dye, textile, rubber, leather, and chemical (especially aromatic amines) industries may be at increased risk.

Personal History of Bladder Cancer: Patients who have had bladder cancer have an increased risk of developing UTUC (and vice versa). This is due to the “field effect,” where the entire urothelium may be at risk.

Prolonged Use of Certain Medications: Such as phenacetin (an analgesic now withdrawn from the market) and cyclophosphamide (used in chemotherapy).

Advanced Age: The risk of UTUC increases with age, being more common in people over 60-70 years old.

Male: UTUC is more common in men than in women.

Hematuria (Presence of Blood in the Urine): It is the most common symptom, occurring in about 70-80% of patients. Hematuria can be:

• Macroscopic: Blood visible to the naked eye, turning the urine pink, red, or the color of “Coca-Cola”.
• Microscopic: Blood detected only through urine analysis.
• It is usually painless, but may be accompanied by blood clots.

Flank or lower back pain: Pain in the side of the back or abdomen, on the side of the affected kidney. This pain may be caused by obstruction of urine flow by the tumor (leading to dilation of the kidney – hydronephrosis), by the formation of clots, or by direct invasion of the tumor into the surrounding tissues.

Constitutional Symptoms (General): These tend to appear in more advanced stages of the disease and may include:

• Unexplained weight loss.
• Persistent and intense fatigue.
• Fever (with no other apparent cause).
• Anemia

Palpable Abdominal Mass: In cases of very large tumors or significant hydronephrosis, it may be possible to palpate a mass in the abdomen.

Irritative Urinary Symptoms: Symptoms such as urgency to urinate, increased urinary frequency, or pain during urination (dysuria) are less common in UTUC than in bladder cancer, but can occur if the tumor is located near the junction of the ureter and bladder.

Medical History and Physical Examination: The doctor will ask about your symptoms, risk factors, and medical history.

Urine Analysis and Urinary Cytology: Urinalysis (Type II) can confirm the presence of blood. Urinary cytology involves observing exfoliated cells in the urine under a microscope, looking for cancerous cells. Cytology is more sensitive for high-grade tumors.

Imaging Tests:

• Uro-Computed Tomography (Uro-CT or CT Urogram): It is considered the gold standard imaging test for the diagnosis and staging of urinary tract infections (UTUC). This test uses X-rays and a computer to create detailed images of the urinary tract. It requires the administration of intravenous iodinated contrast and includes several image acquisition phases (non-contrast, arterial, nephrographic, and excretory or late) to visualize the collecting system, identify tumors (such as filling defects or wall thickenings), assess their extent, and look for signs of spread to lymph nodes or other organs.
• Magnetic Resonance Urography (MRU): It is a valid alternative to CT urography for patients who have contraindications to the use of iodinated contrast (e.g., severe allergy or significant renal insufficiency).
• Renal Ultrasound (Echocardiography): It can detect hydronephrosis (dilation of the kidney) or larger renal masses, but it is less sensitive and specific for the diagnosis of UTUC than CT urography.

Ureterorenoscopy (URS) with Biopsy: This is a fundamental and often definitive endoscopic procedure for diagnosis. A thin, flexible instrument with a camera at the tip (ureteroscope) is inserted through the urethra and bladder, and then up the ureter to the renal pelvis. This allows:

• Direct View: Detailed examination of the urothelial lining looking for suspicious lesions.
• Biopsy: Small tissue samples are collected from suspicious areas for histopathological analysis (under a microscope). The biopsy confirms the presence of cancer, determines its type and, crucially, its degree of aggressiveness. In some cases, it can give an idea of ​​the depth of invasion.

Retrograde Pyelography: During cystoscopy or ureteroscopy, a contrast agent may be injected into the ureter to obtain radiographic images of the collecting system, helping to delineate the anatomy and identify filling defects suggestive of a tumor.

Tumor Grade: Tumor grade assesses how abnormal the cancer cells look under a microscope. This is a predictor of the tumor’s aggressiveness and rate of growth.

• Low Grade: Cells closely resemble normal urothelial cells. These tumors are generally less aggressive and grow more slowly.
• High Grade: Cells are markedly different from normal cells and appear disorganized. These tumors are more aggressive, have a higher likelihood of invading deeper tissues, and are more likely to spread (metastasize).

Tumor Stage: Tumor stage describes the extent of the cancer’s spread. This includes the tumor’s size, the depth of invasion into the renal pelvis or ureter wall layers, involvement of nearby lymph nodes, or spread to distant organs (metastases). The TNM (Tumor, Lymph Nodes, Metastases) system is the standard staging method. In simpler terms, stages can be categorized as:

• Localized/Non-Muscle Invasive Disease: The cancer is confined to the superficial layers of the urothelium (Ta, Tis, T1).
• Muscle Invasive Disease: The cancer has invaded the deeper muscle layers of the renal pelvis or ureter wall (T2, T3, T4).
• Metastatic Disease: The cancer has spread to regional or distant lymph nodes, or to distant organs such as the lungs, liver, or bones.

Standard Treatment for Invasive or High-Grade UTUC:

• Radical Nephroureterectomy (RNU):This is the standard and potentially curative surgical treatment for most patients with invasive or high-grade UTUC. It consists of the complete removal of the kidney, the entire ureter (from the kidney to the bladder), and a small portion of the bladder (“bladder cuff”) at the point where the ureter inserts. Removal of regional lymph nodes (lymphadenectomy) is also frequently performed, as it may have staging and possibly therapeutic value.
• Open RNU: Performed through one or two larger abdominal or lumbar incisions
• Laparoscopic RNU: Performed through several small incisions, using a video camera and long, thin surgical instruments.
• Robot-Assisted RNU: This is a minimally invasive approach that has become a preferred option in many specialized centers. The surgeon controls robotic arms with highly precise and articulated instruments.
• Advantages of Robotic RNU:It offers an enlarged, high-definition three-dimensional view, greater precision and dexterity of the instruments, facilitating meticulous dissection of the kidney, the ureter along its entire length, and the bladder ring. It also allows for a potentially more complete and precise lymphadenectomy. Generally, it results in less blood loss, less postoperative pain, faster recovery, a shorter hospital stay, and better aesthetic results, while maintaining the same oncological principles as open surgery.

• Conservative Approaches to the Kidney (Nephron-Sparing Surgery, NSS):

  • These options are generally reserved for a very select group of patients, specifically those with low-risk tumors (small, low-grade, non-invasive, and unifocal) or those for whom preserving renal function is critical (such as patients with a solitary kidney, significant chronic renal failure, or bilateral UTUC). These approaches require very rigorous and frequent endoscopic surveillance after treatment due to the high risk of tumor recurrence in the upper urinary tract.
  • Endoscopic Resection or Ablation (via Ureteroscopy): Use of LASER (Holmium or Thulium) or electrocautery to destroy the tumor visualized through the ureteroscope. Indicated for small, low-grade tumors in the renal pelvis or ureter.
  • Segmental Ureterectomy: Surgical removal of only the segment of the ureter containing the tumor, followed by reconstruction of the ureter (anastomosis of the ends). Indicated for low-grade, non-invasive tumors located in the middle or distal ureter. Can be performed via open surgery, laparoscopy, or robotic surgery.

  • Systemic Chemotherapy:

    • Neoadjuvant Chemotherapy (Before Surgery): It can be administered before NUR in patients with large, locally advanced tumors or suspected lymph node involvement. The goal is to reduce tumor size, treat possible micrometastases (cancer cells that have already spread but are not detectable), and potentially improve surgical outcomes. Cisplatin-based regimens are generally used.
    • Adjuvant Chemotherapy (After Surgery): It may be considered after NUR if analysis of the surgical specimen reveals high-risk characteristics (e.g., deep tumor invasion, positive lymph nodes), in an attempt to reduce the risk of disease recurrence.
    • Chemotherapy for Metastatic Disease: It is the primary treatment for UTUC, which has already spread to other organs.

  • Systemic Immunotherapy:

    • Agents such as pembrolizumab or atezolizumab (which are immune checkpoint inhibitors and “unlock” the immune system to attack cancer) have demonstrated efficacy in treating patients with advanced or metastatic UTUC, especially after progression with platinum-based chemotherapy, or as first-line treatment in patients who are not candidates for cisplatin.

  • Prophylactic Instillation of Chemotherapy into the Bladder:

    • Following radical nephroureterectomy, a single instillation of a chemotherapeutic agent (such as mitomycin C) into the bladder is often recommended immediately post-operatively. This measure aims to reduce the risk of developing a new urothelial tumor in t

Due to the significant risk of UTUC recurrence (either at the original site, although rare after complete NUR, or in other parts of the urothelium, especially the bladder, or in the contralateral urinary tract), medical follow-up after treatment is crucial and usually lifelong.

The surveillance plan is individualized and depends on each patient’s risk of recurrence. It typically includes:

• Regular Cystoscopy: To examine the inside of the bladder and detect new tumors early.
• Periodic CT or MRI Urographs: To assess the remaining upper urinary tract, the surgical area, and to look for signs of local recurrence or metastases.
• Urinary Cytology.
• Ureteroscopy of the Contralateral Upper Urinary Tract: It may be necessary in some patients, especially if there are high risk factors.
• The frequency of these tests is higher in the first few years after treatment and then gradually decreases.

The most crucial factors determining the prognosis for UTUC are the stage (how far the tumor has invaded) and the grade (the aggressiveness of the cancer cells) at the time the diagnosis is made.

Low-grade, non-invasive (superficial) tumors generally have a good prognosis with appropriate treatment, although they require close monitoring due to the risk of recurrence.

High-grade tumors, or those that invade the deeper layers of the ureter/renal pelvis wall, or that have spread to the lymph nodes or other organs, have a more guarded prognosis.

Early diagnosis, treatment by an experienced multidisciplinary team, and rigorous follow-up are essential to achieving the best possible results.

High urothelial neoplasia is a type of urological cancer that, although relatively rare, requires timely diagnosis and highly specialized treatment. Significant advances in diagnostic imaging techniques, endoscopic procedures, and minimally invasive surgical approaches, such as robotic surgery, have improved therapeutic options and patient outcomes.

If you have been diagnosed with a high urothelial neoplasm, or if you are experiencing symptoms such as blood in your urine or persistent flank pain, it is crucial to seek evaluation by a urologist experienced in treating this condition. A multidisciplinary approach, involving urologists, medical oncologists, radiologists, and pathologists, is essential to define the most appropriate and personalized treatment plan for your case.

We have the latest technology, including robotic surgery, and a dedicated and experienced team to provide the best possible care. Schedule a consultation for a detailed evaluation and to discuss your treatment options.

The Urothelium: The bladder is a hollow muscular organ that stores urine. It is lined internally by a specialized, elastic cellular tissue called the urothelium (or transitional epithelium). This lining is designed to protect the body’s tissues from the waste products contained in urine.

Bladder Neoplasia (Bladder Cancer): This is a cancer that originates in the urothelial cells that line the inside of the bladder. Because the same type of cells line the entire urinary tract, bladder cancer is histologically related to cancers of the renal pelvis and ureters (UTUC), although it occurs much more frequently.

Smoking: This is the most important and well-established risk factor. Carcinogenic substances in tobacco smoke are absorbed into the blood, filtered by the kidneys, and stored in the bladder. While in the bladder, they remain in prolonged contact with the urothelium, causing cellular damage.

Occupational Exposure: Workers in the rubber, leather, textile, dye, and paint industries may be exposed to chemicals known as aromatic amines, which increase cancer risk.

Chronic Bladder Irritation: A history of chronic urinary tract infections, long-term use of urinary catheters, or bladder stones can increase the risk of specific types of bladder cancer.

Personal or Family History: Individuals who have had urothelial tumors in the upper urinary tract are at higher risk of developing tumors in the bladder (and vice versa) due to the “field effect” on the urothelium.

Advanced Age and Sex: The risk increases with age, and men are roughly three to four times more likely than women to develop the disease.

Previous Treatments: Certain chemotherapy drugs (like cyclophosphamide) or pelvic radiation for other cancers can increase the risk.

Hematuria (Presence of Blood in the Urine): This is the most common symptom, occurring in the vast majority of cases. It is characteristically painless and can be:

• Macroscopic: Visible to the naked eye (pink, red, or cola-colored).
• Microscopic: Detected only through laboratory analysis.

Irritative Urinary Symptoms: Symptoms such as an urgent need to urinate, increased frequency of urination, or a burning sensation (dysuria). These are often mistaken for infections but can indicate the presence of a tumor.

Advanced Symptoms: Pain in the pelvic region, lower back pain, unexplained weight loss, or persistent fatigue.

Medical History and Physical Examination: Including an assessment of smoking history and chemical exposure.

Urinalysis and Urinary Cytology: To check for blood and search for malignant cells shed from the bladder lining into the urine.

Imaging Tests

• Ultrasound: Often the first test to identify a mass in the bladder.
• Uro-Computed Tomography (Uro-CT): The gold standard for staging, allowing the urologist to see the tumor’s size and check if it has spread to lymph nodes or other organs.

Cystoscopy: A fundamental procedure where a thin camera is inserted through the urethra to allow a direct view of the bladder’s interior.

Transurethral Resection of Bladder Tumor (TURBT): If a lesion is found during cystoscopy, a TURBT is performed. This is an endoscopic surgical procedure to remove the tumor. The tissue is then sent for histopathological analysis to determine the type, grade, and depth of invasion.

Tumor Grade: Assesses how aggressive the cells look.

• Low Grade: Cells look similar to normal cells; these tumors grow slowly and are less likely to invade the bladder wall.
• High Grade: Cells look disorganized and abnormal; these are more aggressive and more likely to spread.

Tumor Stage: Describes how deep the cancer has grown into the bladder wall.

• Non-Muscle Invasive (Superficial): The cancer is limited to the inner lining or the layer just beneath it (Ta, Tis, T1).
• Muscle-Invasive: The cancer has grown into the thick muscular wall of the bladder (T2+).
• Metastatic: The cancer has spread to distant organs or lymph nodes.

Regular Cystoscopy: Periodic checks of the bladder (or the surgical site).

Urinary Cytology.

Periodic Imaging (CT or MRI): To monitor for any signs of the disease returning in the urinary tract or other organs.

Precision: The robotic platform provides a high-definition 3D view and instruments with greater range of motion than the human hand, allowing for a more precise removal of the bladder and a more thorough lymphadenectomy (lymph node removal).

Recovery: Because the procedure is performed through small incisions, patients generally experience significantly less blood loss, less postoperative pain, a shorter hospital stay, and a faster return to normal activities.

Reconstruction: The robot also facilitates the delicate reconstruction of a new bladder (neobladder) or other urinary diversions with high accuracy.

Bladder cancer is a serious but highly treatable condition, especially when detected early. If you experience blood in your urine—even if it only happens once and is painless—it is critical to seek an evaluation by a urologist. Significant advances in robotic surgery and targeted therapies have refined our ability to treat this disease while maintaining a high quality of life for our patients. Our team is dedicated to providing the most advanced care and supporting you through every step of your journey.
