[Modified urethral pull-through procedure for posterior urethral stricture or atresia]

Area of Science:

• Urology
• Surgical Procedures
• Reconstructive Surgery

Background:

• Posterior urethral stricture and atresia present significant challenges in urological treatment.
• Previous surgical attempts may have limited success, necessitating alternative approaches.

Purpose of the Study:

• To assess the feasibility and safety of a modified urethral pull-through procedure.
• To evaluate its efficacy in treating posterior urethral stricture or atresia.

Main Methods:

• Retrospective analysis of 212 patients with posterior urethral stricture or atresia.
• The modified urethral pull-through procedure was employed, with variations in surgical approach and the use of grafts in some cases.

Main Results:

• A high success rate of 93.4% (198/212) was achieved with satisfactory voiding.
• The procedure demonstrated a favorable safety profile with no serious complications.
• Substitution urethroplasty was successful in 14 out of 15 patients with longer strictures.

Conclusions:

• The modified urethral pull-through procedure is a safe, minimally invasive, and effective option for posterior urethral stricture or atresia.
• For strictures exceeding 5 cm, substitution urethroplasty is a viable alternative.
• The procedure offers a high success rate and is technically straightforward.
