Experience with two-stage scrotal flap urethroplasty for stricture.

A series of 50 men with variously-caused stricture of the bulbar and/or membranous urethra is presented. The 2-stage scrotal flap urethroplasty described by Blandy was used. As a rule the operation was technically simple. Post-operative incontinence was not a problem. Recurrence or new stricture appeared in 7 cases, but 5 of these strictures were short and could be corrected with internal urethrotomy. Timed micturition showed improved voiding in all of the 18 patients studied before and after urethroplasty. Urodynamic studies in the last 8 cases of the series before and after urethroplasty showed significantly improved urinary flow and voiding post-operatively, with reduction of detrusor pressure and residual urine.
