title: The management of strictures of the membranous urethra.
abstract: We present 40 cases of posterior urethral stricture resulting from pelvic fracture injury or prostatectomy. The strictures were managed according to various factors but most important were stricture length and the absence of pathological conditions in the anterior urethra. Post-traumatic obliterative strictures less than 2 cm. long can be managed with excellent success via a 1-stage perineal bulboprostatic anastomotic repair. Combined abdominoperineal procedures are equally successful but are reserved for patients in whom the stricture is more than 2 cm. long or who have an associated bladder neck pathological condition. When associated anterior urethral disease mitigates against mobilization and extension of the urethra to accomplish an anastomotic repair, the vascularized island flap or 2-stage scrotal inlay procedure appears to be the optimal choice. Of 3 failures with full thickness skin grafts 2 may have been owing to suboptimal graft beds in the scarred pelvic floor and perineum. Direct vision urethrotomy is advocated for nonobliterative posttraumatic strictures, and the rationale for dilation rather than urethroplasty management of postprostatectomy strictures is presented.
