Abstract:

Background: We report the outcomes of temporary vesicostomy- assisted anastomotic urethroplasty in patients with recurrent obliterated posterior urethral stricture.Methods: A review of the medical records identified 12 men (mean age 35.8 years) who had undergone anastomotic urethroplasty for recurrent obliterated posterior stricture. Preoperative evaluation of the urethral defect included a simultaneous retrograde urethrogram and cystogram. The mean estimated preoperative radiographic length of the urethral disruption was 4.25 cm. All patients underwent 1-stage bulboprostatic anastomotic repair which was assisted by an intraoperative temporary vesicostomy.Results: The initial objective success rate was 83%. The mean follow-up was 22 months. Voiding cystourethrography performed postoperatively demonstrated a wide, patent anastomosis in all but two cases. Urethroscopy performed 1 month after surgery revealed a patent anastomosis with normal urethral mucosa in all but two patients. The mean peak flow rate at the last follow-up visit was 16.3 ml/s. Two patients developed an anastomotic stricture 6 weeks after surgery that was successfully treated by direct visual internal urethrotomy. Finally, all patients had a patent urethra after salvage treatment postoperatively.Conclusion: An open 1-stage temporary vesicostomy- assisted urethroplasty for recurrent obliterated posterior urethral stricture provides satisfactory outcomes and minimal morbidities.
