Porcine small intestinal submucosa is not an ideal graft material for Peyronie's disease surgery.
OBJECTIVE
The incidence of Peyronie's disease is up to 7% in some series. While there are numerous nonsurgical methods of treatment, they do not have a high rate of success. Nesbit plication was once the accepted surgery for Peyronie's disease. Tunical lengthening procedures became popular because they avoided penile shortening caused by the Nesbit procedure. More urologists now perform plaque incision or excision, followed by grafting with different materials. Small intestinal submucosa offered promise as an ideal graft material. It is available off the shelf as 1 or 4-ply graft material. In several studies it appeared to function as a collagen based scaffold with graft incorporation in host tissue.


METHODS
A single reconstructive urologist performed plaque incision and small intestinal submucosa grafting in 4 cases of Peyronie's disease using the same surgical technique.


RESULTS
Although early results were positive, we have achieved less than satisfactory results with this material. The penis was straight in the immediate postoperative period but there was recurrent curvature in 3 of the 4 patients, of whom 2 had recurrence within 4 months of the procedure.


CONCLUSIONS
We observed disappointing results with small intestinal submucosa for Peyronie's disease surgery with a high percent of recurrent curvature. Further studies are needed to determine if 1 or 4-ply small intestinal submucosa is an ideal graft material for the tunica albuginea.
