Abstract:
Objective To study the application of pediculated skin flaps in the treatment of com-plicated long urethratresia. Methods From March 1999 to May 2006, a total of 18 male patients with complicated long urethratresia were treated by using the pediculated skin flaps. The causes of urethratresia were 7 cases of postoperative pelvic fractures with posterior urethral stricture, 4 cases of transurethral intravesical chemotherapy, 3 cases of postoperative bulbar urethral stricture, 2 cases of gonorrhea, and 2 cases of long-time urethral catheter placement. Four cases were urethratresia nf cor-pus penis, 7 cases were anterior urethral obliteration, 7 cases were posterior urethral and anterior ure-thral obliteration. Urethro-perineal fistulas were found in 8 cases, posterior urethrorectal fistulas in 7 cases, false passage formations in 8 cases. The average length of urethratresia was 15.1 cm (range 8. 7 to 23. 0 cm). The urethral scar was rasected, the posterior urethrorectal fistula was repaired, and different kinds of pediculated skin flaps depending on the length of urethratreaia was used. Results All the patients were followed up for 12 to 18 months (mean 14 months). Fifteen patients voided well 3 months postoperatively, none of the urography showed stricture. The mean peak urinary flow rate was 16. 9 ml/s (range from 16. 5 to 21.7 ml/s). Of the other 3 cases, 1 case experienced difficult voi-ding due to the long and circuitous tabularized skin flap but recovered after proper shortening;1 case had restenosis for the infection of anastomosis but voided well after excision and reanastomnsis;1 casehad a urinary fistula resulting from hematoma and infection, but was successfully treated by the neo-plasty of the urinary fistula. The mean peak urinary flow rate was 17.0 ml/s (range 15.0 to 22.0 ml/s) for 17 patients 6 months postoperatively, except for one who experienced genuine urinary incon-tinence. At 9-18 months after operations, the mean peak urinary flow rate was 17.5 ml/s (range 15.8 to 22.5 ml/s) for 17 patients. Conclusion The single-stage urethroplasty based on pediculated skin flaps is a reliable and durable method for complicated long urethratresia.
