[Treatment of urethral stenosis using a pedicled flap of the scrotal skin. Long-term results in 16 patients].

The scrotal skin is vascularized in part by means of the superficial perineal branch of the internal pudendal artery. This nutrient pedicle, together with the scrotal skin dependent on it, can be isolated. The urethra is approached via the perineum. The stricture is incised longitudinally right down to the healthy area. The scrotal flap and pedicle are mobilized, and then anastomosed along the edges of the urethra. From March 1983 through April 1987, sixteen patients have been operated. Postoperative results: the mean follow-up for the 16 patients is 60 months with extremes of 24 and 66 months. 13/16 patients show good results (81%). 3/16 patients show poor results with recurrence of the stricture localized at the junction of the flap and healthy urethra. Such recurrences have yielded to treatment, in two cases, by optical urethrotomy and, in the other case, by means of a new scrotal flap.
