Use of Small Intestinal Submucosa for Corporal Body Grafting in Cases of Severe Penile Curvature
2002
ABSTRACTPurpose: Small intestinal submucosa is a unique biomaterial that has been found to promote tissue specific regeneration in the urinary tract. We present our experimental and clinical experience with small intestinal submucosa (SurgiSis, Cook Biotech, Spencer, Indiana) for pediatric corporal body reconstruction.Material and Methods: A total of 20 Fischer rats underwent implantation of a 7 × 3 mm. small intestinal submucosa graft following excision of an ellipse of tunica albuginea and 14 control animals underwent tunical excision with reimplantation of this autologous segment. The animals were euthanized, and the penis was sectioned and histologically studied at intervals of 1, 2, 4, 6, 16 and 24 weeks. In 15 pediatric patients small intestinal submucosa was used for corporal body grafting. The grafting procedure was performed along the ventral (hypospadias cases) or dorsal (epispadias cases) surface of the corporal bodies. The tunica albuginea was incised full thickness at the point of maximal cur...
