摘要
Purpose: We present our preliminary experience with operative approaches to the treatment of complex posterior urethral distraction defects in children. Materials and 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.
