Perineal repair of pelvic fracture urethral distraction defects: experience in 120 patients during the last 10 years.
PURPOSE: We report the long-term success of a 1-stage perineal anastomotic repair in patients with pelvic fracture urethral distraction defects. MATERIALS AND METHODS: A retrospective analysis of 120 patients undergoing perineal bulboprostatic anastomotic repair of pelvic fracture urethral distraction defect in a single stage using our progressive approach between May 1991 and May 2001 was performed. Patients with posterior urethral stricture due to other etiologies, or those who underwent substitution urethroplasty or abdominoperineal repair were excluded from this review. Preoperative evaluation of the urethral defect included simultaneous retrograde urethrogram and voiding cystourethrogram. Postoperative retrograde urethrogram was performed at 3 weeks, 3 months, 12 to 18 months and as indicated thereafter. RESULTS: Mean patient age was 32 (range 6 to 82) years. The estimated preoperative radiographic length of the distraction defect was 3.1 cm (range 0.5 to 10). Mean followup was 64 (range 9 to 128) months, mean hospital stay was 1.8 days and duration of urethral stenting was 3.4 weeks. Perineal anastomotic repair was successful in 103 of 109 (95%) adults, in 8 of 11 (73%) prepubescent boys and in 25 of 29 (86%) undergoing secondary repairs. All treatment failures were at the anastomosis and occurred within the first postoperative year. Successful management of failed repairs was accomplished endoscopically in 3 of 7 and by repeat perineal anastomotic repair in 2 of 2, resulting in a final success rate of 97% in adults, 91% in prepubescent boys and 97% in secondary repairs. CONCLUSIONS: The overall success of our progressive 1-stage perineal anastomotic repair of pelvic fracture urethral distraction defect continues to be excellent with the majority of failures occurring in prepubescent boys and secondary repairs.
