OBJECTIVE: To compare the results and complication rates of various one-stage treatments for repairing a post-traumatic urethral stricture. PATIENTS AND METHODS: The medical records of 153 patients who had a post-traumatic urethral stricture repaired between 1977 and 2003 were evaluated retrospectively, and analysed for the different types of urethral reconstruction. RESULTS: The procedures included direct end-to-end anastomosis in 86 (56%) patients, free dorsal onlay graft urethroplasty using preputial or inguinal skin in 40 (26%), ventral onlay urethroplasty using buccal mucosa in seven (5%) and ventral fasciocutaneous flaps on a vascular pedicle in 20 (13%). At a mean (median, range) follow-up of 75.2 (38, 12-322) months, 121 (79%) patients had no evidence of recurrent stricture, while in 32 men (21%) they were detected at a mean follow-up of 30.47 (1-96) months. Patients having a dorsal onlay urethroplasty had the longest strictures. The re-stricture rate was lowest after a dorsal onlay urethroplasty (5% vs 27% when treated with end-to-end anastomosis, 15% after fasciocutaneous flaps and 57% after a ventral buccal mucosal graft). The surgical technique used had no effect on postoperative incontinence or erectile dysfunction rates. CONCLUSION: In patients with strictures which are too long to be excised and re-anastomosed, tension-free dorsal onlay urethroplasty is better than ventral graft or flap techniques. In patients with short urethral strictures direct end-to-end anastomosis remains an option for the one-stage repair of urethral stricture.
