Abstract

Purpose: We investigate whether the short-term success rate (greater than 90%) of buccal mucosa free grafts in the bulbar urethra is sustained in the long term. Materials and Methods: In 60 patients a ventrally placed buccal mucosa graft was used for repair of bulbar urethral strictures. Of these patients 49 had undergone previous attempt at repair (urethroplasty in 4, internal urethrotomy in 45). Mean graft length was 4.8 cm. In 9 patients a distal penile fasciocutaneous flap was also used for repair of concomitant penile urethral stricture. In 8 of the 9 patients the buccal mucosa graft was combined with end-to-end urethroplasty and 2 buccal mucosa grafts were used in tandem in 1. Followup was at least 1 year in all cases (mean 47 months, range 12 to 107). Failure was defined as an obstructive voiding pattern with radiographic or cystoscopic evidence of recurrent stricture. Results: Bulbar stricture repair was successful in 54 patients (90%) and 4 of the remaining 6 responded to 1 internal urethrotomy for a long-term success rate of 97%. Preoperative clinical characteristics were not significantly different between those who experienced success or failure. Conclusions: Long-term outcome analysis of ventrally placed buccal mucosa onlay grafts for bulbar urethral strictures demonstrates a durable success rate of 90%. This rate can be improved (97%) with the judicious use of internal urethrotomy.
