An evaluation of surgical approaches for posterior urethral distraction defects in boys.
OBJECTIVE
We present our preliminary experience with operative approaches in the treatment of complex posterior urethral distraction defects in children.


METHODS
A total of 24 boys 7 to 14 years old with obliterative complex posterior urethral distraction defects were treated with 1 of 3 surgical approaches between January 1998 and December 2002. A perineal approach was used in 5 cases, a transperineal-inferior pubic approach including distal urethral mobilization, corporeal body separation and inferior pubectomy in 10, and a combined transpubic-perineal approach in 9.


RESULTS
Patients were followed 1 to 5 years postoperatively. A successful result of no recurrence of stricture was achieved in 19 of 24 patients (79.2%), including 3 of 5 (60%) treated with a perineal approach, 9 of 10 (90%) with a transperineal-inferior pubic approach and 7 of 9 (77.8%) with a transpubic-perineal approach. Complications included 1 combined false passage, which was resolved using a transperineal-inferior pubic approach, 2 urethrocutaneous fistulas, which were resolved using a perineal approach in 1 and a transpubic-perineal approach in 1, and 3 rectourethral fistulas, which were resolved using a transpubic-perineal approach in 1 and a transperineal-inferior pubic approach in 1. Of the 9 patients treated with the transpubic-perineal approach 3 walked with an abnormal gait postoperatively.


CONCLUSIONS
The transperineal-inferior pubic approach fully exposes the space behind the pubis, does not damage pelvic stability and yields better results compared to the perineal and transpubic-perineal approaches. We recommend it as first line operative treatment for complex posterior urethral distraction defects in boys.
