title: Optimal management of the 3- to 6-centimeter anterior urethral stricture.
abstract: The optimal management of anterior urethral stricture that does not respond to an endoscopic urethrotomy or is found to be unsuitable for excision and anastomotic repair remains controversial. Genital skin island onlay flaps or buccal mucosal grafts are presently the most dependable single stage procedures used for strictures more than 3 cm in length. Nonhirsute penile island fasciocutaneous flaps constitute the most durable substitution technique for pendulous stricture disease, with long-term studies reporting 90% to 96% success. The complex proximal bulb and bulbomenbraneous stricture with a compromised proximal fibrous avascular bed is ideally managed with either a penile or scrotal island flap or some combination of partial urethral excision with a dorsally placed genital skin island. The buccal mucosal onlay graft is a promising addition to this reconstructive paradigm, and early outcomes have been favorable. The graft is presently used for bulbar strictures, avoiding the transsphincteric on pendulous location, or a compromised recipient bed. The present standard of care for proximal bulb strictures is wide bulbospongiosal mobilization, partial urethral excision, a floor strip anastomosis, and placement of an augmenting flap on the graft in a dorsal location.
