Management of posttraumatic posterior urethral disruption.

: We reviewed our experience with 17 cases of posterior urethral disruption due to traumatic pelvic injuries. In all cases, a suprapubic cystostomy was performed at first. For blunt injuries, urethroplasty was delayed for 6 months in average. For most of the penetrating injuries (3/4), we performed immediate debridement and primary repair. Resulting bulbous or membranous strictures less than 3 cm long were treated with one-stage perineal excision-reanastomosis urethroplasty. Membranous strictures longer than 3 cm were managed with a combined transpubic-perineal repair, while bulbous defects longer than 3 cm were treated with a scrotal pedicled island flap. The overall restricture rate was 25%. Those having had initial repeated urethrotomies displayed a 100% restenosis rate. Incontinence rate was 12.5% Erectile dysfunction occurring in 42% of our patients is a sequela of the pelvic injury and was found to be directly related postoperatively to its presence at the time of surgery.
