Urethral stricture is a common presentation at my urology office, defined as a narrowing of a segment of the urethra. US data reports a 0.9% incidence in men, with dramatically increasing prevalence after age 65.

The 4 major causes of urethral stricture

1. Idiopathic (33% incidence) — more common in younger males; likely represents unrecognized childhood trauma or congenital anomaly
2. Iatrogenic (33% incidence) — history of transurethral endoscopic surgery or long-term indwelling urethral catheter
3. ရောင်ရမ်းခြင်း။ (15% incidence) — history of urethral infection, particularly sexually transmitted diseases (STDs)
4. စိတ်ဒဏ်ရာ (19% incidence) — blunt straddle injury, pelvic fracture, or penile fracture

Regardless of the cause, urethral damage triggers scar formation that gradually narrows the urethral canal over weeks, months, or years. Patients typically present with weak urinary stream or discomfort during urination. Evaluation involves flexible cystoscopy as first-line visualization, followed by retrograde urethrography (contrast study) if needed to define the stricture length and location.

Treatment options for urethral stricture

1. ဆီးလမ်းကြောင်း ချဲ့ခြင်း။ — serial dilation with metallic dilator; comparable results to surgery but 60% recurrence rate at 48 months follow-up
2. တိုက်ရိုက်အမြင်အာရုံအေးဓား urethrotomy — endoscopic incision of the stricture under direct vision; 50% recurrence rate at 48 months
3. တိုက်ရိုက်အမြင်အာရုံလေဆာ urethrotomy — same approach as cold knife but using laser technology; comparable outcomes
4. ဆီးသွားခွဲစိတ်ကုသခြင်း။ — gold standard for strictures longer than 2 cm; highest long-term success rate of all treatment options

Since urethral stricture involves natural scar formation, recurrence is always possible regardless of treatment. Regular follow-up and early detection of recurrence are essential components of long-term management. Treatment choice depends on stricture length, location, etiology, and patient factors.

Frequently Asked Questions About Urethral Stricture

What causes urethral stricture?

Urethral stricture develops from scarring of the urethral wall following tissue damage. The four major causes are: idiopathic (33%) — often related to unrecognized childhood trauma or congenital anomaly; iatrogenic (33%) — from transurethral surgery or long-term catheterization; inflammatory (15%) — from urethral infection or sexually transmitted diseases; and traumatic (19%) — from pelvic fracture, straddle injury, or penile fracture. Regardless of cause, the resulting scar tissue gradually narrows the urethral lumen over weeks to months.

What is the best treatment for urethral stricture?

Treatment selection depends on stricture length and location. For short strictures, options include urethral dilation (60% recurrence at 4 years) or direct vision urethrotomy (cold knife or laser, 50% recurrence at 4 years). For strictures longer than 2 cm, urethroplasty (open surgical reconstruction) is the gold standard, offering the highest long-term success rate. Since all treatments carry a risk of recurrence due to the body’s natural scarring process, regular urological follow-up is essential after any treatment.

What symptoms suggest urethral stricture?

The most common symptom is a progressively weakening urinary stream. Other symptoms may include urinary hesitancy, incomplete bladder emptying (post-void dribbling), straining to urinate, discomfort during urination, recurrent urinary tract infections, and in severe cases, acute urinary retention. If you have a history of pelvic trauma, STDs, prior catheterization, or endoscopic urological surgery and notice changes in your urinary stream, prompt urological evaluation is important.
