[Urethral stricture].

Area of Science:

• Urology
• Surgical Innovation
• Fibrotic Disease Research

Background:

• Urethral stricture involves fibrotic narrowing of the urethra, causing lower urinary tract obstruction, primarily in men.
• Iatrogenic factors are the leading cause in industrialized nations, stemming from inflammation or trauma leading to spongiofibrosis.
• Clinical presentation includes obstructive voiding symptoms, urinary retention, and potential renal complications.

Purpose of the Study:

• To review the pathophysiology, diagnosis, and treatment of urethral strictures.
• To compare the efficacy of various treatment modalities, including minimally invasive and open reconstructive surgeries.
• To highlight the importance of follow-up for managing recurrence.

Main Methods:

• Review of existing literature on urethral stricture etiology, diagnosis, and treatment.
• Analysis of diagnostic tools, including uroflowmetry and retrograde urethrography (gold standard).
• Evaluation of surgical outcomes for dilation, internal urethrotomy, and open urethroplasty (including anastomosis and substitution techniques).

Main Results:

• Minimally invasive treatments for short strictures have high recurrence rates.
• Open urethroplasty demonstrates long-term success rates up to 95% for long or recurrent strictures.
• Autologous oral mucosa grafts and emerging tissue-engineered grafts are effective reconstructive options.

Conclusions:

• Open urethroplasty is the gold standard for complex urethral strictures, offering superior long-term outcomes.
• Structured follow-up is crucial for detecting recurrence and ensuring treatment success.
• Advancements in reconstructive techniques, including tissue engineering, hold promise for improved patient management.
