RESUMEN
Objective@#To evaluate the feasibility of buccal musoca grafting in the treatment of longer anterior urethral stricture.@*Methods@#From January 2012 to December 2017, 42 cases of anterior urethral stricture were treated in staged procedure. Stage 1 included the excision of the narrow urethra and the reconstruction of the urethra by transplanting buccal mucosa sheet or tube. In Stage 2, patients underwent operation including urethra anastomosis and transfer the scrotal flap for coverage, and perform suprapubic puncture cystostomy at the same time.@*Results@#Thirty-eight of 42 cases were followed up for 5-12 months with an average of 8 months. In the followed-up 38 cases, 35 of them obtained satisfactory result. Complications occurred in 2 patients, all of them suffered from urethra restricture. One patient′s urethra stricture was located in the anastomosis, stricture length was 0.5 cm. This patient received excision of the narrow urethra and anastomosis. Stricture in another patient was located in the external urethral meatus, this patient received expansion of the external urethral meatus. With proper treatment, all of them were recovered. One patient was not satisfied with the appearence of penis postoperatively. Of all these patients, no urethral fistula or penile curvature was observed. Urination and ejaculation were normal.@*Conclusions@#A successful treatment of long anterior urethral stricture can be achieved with the excision of affected urethra, reconstruction of defect urethra with buccal mucosa flap in staged procedure, and covering the new urethra by transferring the scrotal flap.
