PURPOSE: During substitution urethroplasty, if the stricture contains a 1 to 2 cm region that is particularly narrow and/or fibrotic, that portion may be excised with subsequent anastomosis of the dorsal or ventral aspect of the urethra to shorten, widen and optimize the urethral wall onto which an onlay graft is to be placed. This procedure is termed augmented anastomotic urethroplasty. To determine the effectiveness of this approach we reviewed our experience with augmented anastomotic urethroplasty in an 8-year period. MATERIALS AND METHODS: We reviewed the records of patients who underwent augmented anastomotic urethroplasty between October 1997 and April 2005. Perioperative characteristics were compared between successes and failures using the Wilcoxon/Kruskal-Wallis and Fisher exact tests. RESULTS: Of 69 patients who underwent augmented anastomotic urethroplasty for recurrent urethral strictures 5 had undergone previous urethroplasty using a genital skin flap or graft. At a median followup of 34 months (range 13 to 103) 62 patients had no evidence of stricture recurrence and required no further intervention for an overall success rate of 90%. Stricture recurrence, defined as the inability to easily pass a standard flexible cystoscope through the area of repair, occurred in 7 patients (10%). Patients with stricture recurrence were significantly older (mean age 52 vs 39 years, p = 0.02) and more likely to experience postoperative urinary tract infection (28% vs 3.2%, p = 0.05) than patients without repeat stricture. CONCLUSIONS: Augmented anastomotic urethroplasty is an effective technique that allows the use of a shorter onlay graft. It may optimize overall results due to improvement in the urethral wall and the associated corpus spongiosum.
