A modified technique for the surgical correction of urethral diverticula using a porcine xenograft.

We report a case of urethral diverticulectomy re-enforced with a porcine xenograft to prevent the risk of recurrence or fistula in the presence of a large urethral communication. The use of porcine small intestinal submucosal xenograft (SIS, Surgisis, Cook, Ireland) material has a low graft rejection rate and erosion is rare as the material is degraded after 3 to 6 months. In this case, xenograft achieved tension-free closure of the urethral defect without any postoperative complications.
