Abstract
PURPOSE: Penile skin flap uretroplasty is a useful technique for a long urethral stricture due to the ample length and surgical handling characteristics. We investigated the surgical technique and initial results of uretroplasty for anterior urethral strictures using a dorsal penile skin flap. PATIENTS AND METHODS: From January 2003 to January 2018, a total of 77 patients underwent substitution urethroplasty using dorsal penile skin flap for bulbar urethral strictures in our institution. All patients were assessed preoperatively, and followed postoperatively by physical examination, urinalysis, retrograde and voiding urethrography, uroflowmetry and post-void residual urine measurement. Success was defi ned as no requirement of additional urethral instrumentation. RESULTS: The mean age was 45 years (10-87). The mean stricture length was 5cm (3-10cm). The mean flap length was 6cm. Urinary fi stula was the most common postoperative complication. The mean follow-up was 60 months (6-120). The overall success rate was 88%. Recurrent strictures were found in 4 patients (5%) at 1 year. At 3 year follow-up, 5 (7%) more patients had recurrences. All recurrences were managed by internal urethrotomy. CONCLUSIONS: Substitution urethroplasty using penile skin fl ap appear to be a safe and effi cient technique for the treatment of a long and complex anterior urethral stricture. It provides encouraging cosmetic and functional results.
