Objectives. To evaluate the efficacy of buccal mucosa in the repair of adult urethral stricture disease, we report our experience with its use as a nontubularized onlay graft during bulbar urethral reconstruction. Methods. From June 1993 to January 1996, 75 men underwent anterior urethral reconstruction for stricture disease. Single-stage urethroplasty with an onlay patch graft of buccal mucosa was performed in 13 patients with complex, refractory strictures of the bulbar urethra. In all cases, a two-team approach was used in which one team harvested the graft from the mouth while the perineal team simultaneously exposed and calibrated the stricture. Results. The length of buccal mucosa ranged from 3.5 to 17 cm (average length 6.2). In 8 patients, other reconstructive techniques were used concomitantly, including fasciocutaneous penile flap or stricture excision and primary anastomosis, depending on the length and severity of the scarred area. Median follow-up time was 18 months. Excellent results were obtained in all 13 patients, and none has required urethral dilation or instrumentation subsequently. Operative time was significantly less than with other forms of substitution urethroplasty. Conclusions. Excellent results can be expected when buccal mucosa is used for urethral substitution in men with refractory bulbar strictures. For patients with long or dense strictures, buccal mucosal grafts may easily be combined with other reconstructive techniques. In patients with less complex stricture disease, the reduced operative time of this two-team approach may be beneficial.
