Buccal mucosal grafts for urethral reconstruction

Objectives: Patients requiring urethral; reconstruction but who have a paucity of usable genital tissue present a considerable technical challenge. Herein we report the experience of three centers in the use of buccal mucosa for urethral replacement. Methods: From 1991 to 1996, 22 urethral reconstructions were completed using a graft of buccal mucosa. Eighteen of 22 patients had previously failed hypospadias repairs, while three had bulbar urethral stricture and one had penile carcinoma. Grafts were taken from either the inner cheek or the lower lip, and seven were used as a combined graft. Onlay grafts were used in 6 cases and tubularized grafts in 16 cases. Results: Two patients developed complications at the donor site. Nine of 22 patients had complications of the urethroplasty-two had meatal stenosis, four developed a urethral fistula, and three developed urethral stricture. All complications have been managed successfully to date. Conclusions: Buccal mucosa is an excellent source of graft material for urethral replacement in complex urethroplasties. It is readily available, in abundant supply, and has physical properties beneficial to free graft survival. (C) 1998, Elsevier Science Inc. All rights reserved.
