Complex posterior urethral disruptions: management by combined abdominal transpubic perineal urethroplasty.
OBJECTIVE
We present our short-term results of abdominal transpubic perineal urethroplasty for complex posterior urethral disruption.


METHODS
From January 2000 to March 2005, 21 patients with complex posterior urethral disruption underwent abdominal transpubic perineal urethroplasty. Complex disruption was defined as stricture gap exceeding 3 cm or associated perineal fistulas, rectourethral fistulas, periurethral cavities, false passages, an open bladder neck or previous failed repair. Preoperative voiding cystourethrogram with retrograde urethrogram and cystourethroscopy were done to evaluate the stricture and bladder neck. Followup consisted of symptomatic assessment and voiding cystourethrogram.


RESULTS
There were 11 adults and 10 prepubescent boys with an average age of 26 years (range 6 to 62). Mean followup +/- SD was 28 months (range 9 to 40). Mean stricture length was 5.2 +/- 1.4 cm. Of the 21 patients 12 had previously undergone failed urethroplasty. The mean period between original trauma/failed repair and definitive repair was 10.2 +/- 4.3 months. Urethroplasty was achieved through the subpubic route in 16 patients, while 5 required supracrural rerouting. In 20 of 21 patients (95%) postoperative cystourethrography showed a wide, patent anastomosis. Postoperative incontinence developed in 2 of 21 patients (9.5%). Seven of the 21 patients (33%) were impotent after the primary injury, while 3 of 14 (21.4%) had impotence postoperatively. There were no complications related to pubic resection, bowel herniation or periurethral cavity recurrence.


CONCLUSIONS
Combined abdominal transpubic perineal urethroplasty is a safe procedure in children and adults. It allows wide exposure to create a tension-free urethral anastomosis without significantly affecting continence or potency. Complications of pubic resection are now rarely seen.
