[Urethral stricture: single-stage urethroplasty by a free skin flap].

A single-stage procedure involving the use of a free skin flap for the correction of urethral strictures was performed on eighteen patients. In this series, the strictures were mainly located in the region of the bulbar urethra. Good results were obtained in fourteen cases (80 per cent) out of the eighteen, with a two year followup, or less. The method is simple and effective. In the authors' experience, it has provided a higher success rate than any other procedure described to date. In view of this high success rate, and the equivalent successes reported in the literature, the authors consider that this technique, and urethrotomy, constitute the treatment of choice for urethral stenosis.
