Abstract

Objective: To report our experience, and to evaluate the long-term outcomes and complication profiles of ventral onlay buccal mucosal graft urethroplasty (BMU) after prior urological intervention. Methods: We retrospectively reviewed 114 consecutive patients between February 2001 and April 2009 who underwent buccal mucosal graft urethroplasty for recurrent anterior urethral stricture disease. Seven patients were excluded for incomplete data. The remaining 107 patients comprised the study cohort. The mean follow-up time was 39.3 months (range 6.6-127.3 months). All patients had prior urological attempts at operative management. Results: The mean stricture length was 3.14cm (range 1.0-8.0cm). Indications for buccal mucosal graft urethroplasty included: lichen sclerosis (2.8%), iatrogenic (24.3%), infection (4.7%) and perineal trauma/straddle injury (20.6%). Of these patients, 78 had bulbo-membranous stricture disease, 20 had penile involvement and nine were multifocal strictures. The average number of prior urological procedures was 2.83 (range 1-9). The overall graft failure rate was 6.5%. Importantly, the re-operation rate was 20.6%, primarily for stricture recurrence (18), meatal stenosis (3) and urethral diverticulum. The mean time to complication was 10.8 months. Conclusions: Ventral onlay buccal mucosal graft urethroplasty offers satisfactory results in the setting of recurrent and complicated urethral stricture disease. Graft failures and complications generally occur within the first year after surgery. Bulbar strictures enjoy greater graft patency and lower complication rates than other stricture locations. In particular, guarded expectations should be given for stricture length >4cm and multifocal disease.
