Reconstruction of the bulbar urethra using dorsal onlay buccal mucosal grafts: New concepts and surgical tricks

Buccal mucosa onlay graft urethroplasty represents one of the most widespread methods for the repair of strictures in the bulbar urethra, because of its thick and highly vascular spongiosum tissue. Recently the location of the patch has become a contentious issue, since we described our original techniques of dorsal onlay graft urethroplasty. The design rationale for this approach was based on the concept that the corporeal body remains a healthy host for receiving a free transplanted tissues. Moreover, graft fixation onto a defined surface may decrease graft shrinkage and sacculation. The success rate using buccal mucosa grafts for the repair of bulbar urethral strictures has generally been high with dorsal or ventral onlay grafts or using an augmented roof-strip anastomotic urethroplasty. We describe here the fundamental concepts of the bulbar urethra reconstruction using buccal mucosal grafts, presenting a new surgical technique of dorsal onlay buccal mucosa graft urethroplasty using fibrin glue.
