ABOUT TREATMENT
Urethroplasty for Urethral Stricture
Urethroplasty is a reconstructive surgical procedure used to treat a urethral stricture, a narrowing of the urethra caused by scar tissue. Urethral stricture can restrict the flow of urine and may lead to symptoms such as a weak or interrupted urine stream, difficulty starting urination, straining, incomplete bladder emptying, or recurrent urinary infections.
Urethroplasty aims to remove or bypass the narrowed section and reconstruct the urethra, helping restore a more normal urinary passage. The appropriate technique depends on the location, length, severity, cause of the stricture, previous treatments, and the patient's individual anatomy.
SYMPTOMS
Common Symptoms
Weak or reduced urine stream
Difficulty starting urination
Straining to pass urine
Slow or prolonged urination
Interrupted or stop-and-start urine flow
Spraying or splitting of the urine stream.
Feeling of incomplete bladder emptying.
Frequent or urgent urination.
Pain or burning during urination
Recurrent urinary tract infections (UTIs)
Blood in the urine in some cases
Urinary retention in severe cases
CAUSES
Causes of Urethroplasty for Urethral Stricture
Previous urethral injury or trauma — including pelvic or perineal injuries.
Medical procedures — such as urethral catheterization, cystoscopy, or other instrumentation.
Previous urethral or prostate surgery.
Previous treatment for urethral stricture — recurrence can occur after dilation or internal urethrotomy.
Infections — certain sexually transmitted or other infections can cause inflammation and subsequent scarring.
Inflammatory skin conditions — particularly lichen sclerosus, which can affect the urethral opening and surrounding tissues.
Radiation therapy involving the pelvis.
Cancer treatment or pelvic surgery in some cases.
Congenital narrowing — rarely, a person may have a narrowing present from birth.
Unknown cause (idiopathic) — in some patients, no definite cause can be identified.
RISK FACTORS
Risk Factors
Previous urethral injury or pelvic trauma
Previous catheterization or urethral instrumentation
History of urethral or prostate surgery
Previous treatment for urethral stricture, such as dilation or internal urethrotomy
Certain urinary or sexually transmitted infections
Lichen sclerosus and other inflammatory conditions
Previous pelvic radiation therapy
Repeated urinary tract procedures
Pelvic fractures or significant perineal injuries
Increasing age, particularly in people with other risk factors
DIAGNOSIS
Diagnosis
Medical History & Physical Examination: The doctor reviews urinary symptoms, previous surgeries, catheterization, injuries, infections, and earlier treatments.
Uroflowmetry: Measures the speed and pattern of urine flow. A reduced or abnormal flow may suggest obstruction.
Post-Void Residual (PVR): Ultrasound or catheter measurement determines how much urine remains in the bladder after urination.
Retrograde Urethrogram (RUG): X-ray imaging with contrast helps show the location and length of the narrowed urethral segment.
Cystoscopy: A small camera is passed through the urethra to directly examine the urethral passage and stricture.
Urine Tests: Urinalysis and urine culture may be performed to check for infection.
Ultrasound or Other Imaging: Additional imaging may be recommended in selected patients, particularly when associated urinary-tract problems are suspected.
TREATMENT OPTIONS
Treatment Options
1. Observation
Very mild strictures with minimal symptoms may sometimes be monitored by a urologist, with follow-up to assess urinary flow and symptoms.
2. Urethral Dilatation
The narrowed urethral segment is gradually widened using specialized instruments. It can provide temporary relief, but strictures may recur, particularly after repeated procedures.
3. Direct Vision Internal Urethrotomy (DVIU)
A small endoscopic instrument is used to make an incision in the scar tissue to widen the urethral passage. It is generally used for selected short strictures.
4. Urethroplasty
Urethroplasty is an open reconstructive surgery designed to provide a more durable repair. Depending on the stricture, it may involve:
Removing the scarred segment and reconnecting healthy urethral ends.
Widening or reconstructing the urethra using a tissue graft, commonly buccal mucosa from the inner cheek.
Staged reconstruction for selected complex strictures.
5. Urinary Diversion or Suprapubic Catheter
In severe obstruction or acute urinary retention, a suprapubic catheter may be used to drain the bladder. This can also provide temporary drainage while definitive treatment is planned.
BENEFITS
Benefits of Treatment
Improved urine flow by widening or reconstructing the narrowed urethral segment.
Relief from urinary symptoms such as weak stream, straining, and difficulty starting urination.
Better bladder emptying when the stricture is causing significant obstruction.
Reduced recurrence compared with repeated endoscopic procedures in appropriately selected patients.
Reduced need for repeated urethral dilatation or endoscopic procedures in suitable cases.
Lower risk of complications from persistent urinary obstruction when the underlying stricture is successfully treated.
Improved quality of life by making urination easier and more comfortable.
Long-term restoration of urethral function in many appropriately selected patients.
RECOVERY
Recovery & Aftercare
Immediately After Surgery
A urinary catheter is usually kept in place temporarily to allow the reconstructed urethra to heal.
Mild pain, swelling, bruising, or discomfort may occur during the initial recovery period.
Pain medicines and other medications may be prescribed by the surgeon.
The catheter and surgical wound require care according to the urologist's instructions.
During Recovery
Patients are generally advised to:
Keep the surgical area clean and follow wound-care instructions.
Avoid strenuous exercise, heavy lifting, cycling, and activities that put pressure on the surgical area until cleared by the surgeon.
Take prescribed medicines as directed.
Maintain adequate hydration unless medically restricted.
Attend scheduled follow-up appointments.
PREVENTION
Prevention
Prevent urethral injury: Use appropriate precautions during activities that may cause pelvic or perineal trauma.
Safe catheterization: Catheters and other urethral instruments should be inserted gently and only when medically necessary.
Treat urinary and genital infections promptly: Appropriate diagnosis and treatment may reduce inflammation and scarring.
Follow post-surgical instructions: Proper follow-up after prostate, urethral, or pelvic procedures can help identify complications early.
Manage inflammatory conditions: Conditions such as lichen sclerosus should receive appropriate medical treatment and follow-up.
Avoid unnecessary repeated urethral procedures: Repeated instrumentation can itself contribute to urethral scarring.
Attend follow-up after previous stricture treatment: Early detection of recurrent narrowing allows timely management.
COMPLICATIONS
Possible Complications
Acute urinary retention — inability to pass urine, which requires urgent medical treatment.
Incomplete bladder emptying — urine may remain in the bladder after urination.
Recurrent urinary tract infections (UTIs) due to urinary stasis.
Bladder problems — prolonged obstruction can cause changes in bladder function.
Bladder stones — incomplete emptying can contribute to stone formation.
Urinary leakage or incontinence in some patients.
Kidney problems — severe or prolonged obstruction can, in some cases, affect the upper urinary tract and kidney function.
Recurrent urethral stricture even after treatment.
Reduced quality of life due to persistent urinary symptoms and difficulty passing urine.
