Endourethral urethroplasty with prepuce graft for long posterior urethral stricture

Twenty patients underwent endourethral urethroplasty with free prepuce graft in combination with transurethral resection of scar for posterior urethral stricture. Two-year follow-up showed that they had good continent and free voiding results. Problems about surgical technique were detailed. We conclude that a free full-thickness prepuce evenly patched by means of the tube balloon to the freshly prepared wound derived from the stricture is the key to surgical success.
