Multi-institutional experience with buccal mucosa onlay urethroplasty for bulbar urethral reconstruction.

Purpose: Buccal mucosa has been advocated as an ideal graft material for urethral reconstruction. We report our multicenter experience with buccal mucosa ventral onlay urethroplasty for complex bulbar urethral reconstruction in adults.Materials and Methods: A retrospective analysis of patients who had undergone buccal onlay urethroplasty at 4 military medical treatment facilities participating in the Uniformed Services Urology Research Group was performed. The database generated included demographic data, genitourinary history, preoperative symptoms (American Urological Association symptom score), preoperative urinary flow rate, stricture length and operative statistics. Postoperative followup data included symptom score, flow rate, retrograde urethrogram results, and complications.Results: A total of 53 patients (average age 32 years, range 17 to 64) underwent buccal mucosa graft urethroplasty between January, 1996 and March, 1998 for refractory strictures. Sixteen patients had undergone an average of 2....
