Abstract

Purpose

We report outcomes and complications of the use of porcine small intestine submucosa for correcting penile curvature due to Peyronie's disease.

Materials and Methods

A retrospective study was performed in patients with severe penile curvature (greater than 60 degrees) requiring surgical correction for sexual function. Preoperatively all patients underwent evaluation, including history, physical and penile duplex ultrasound. Of these patients 19 underwent tunical grafting with 1-layer Surgisis® small intestine submucosa. Postoperatively patients were evaluated with clinic visits and telephone interviews to assess results.

Results

A total of 19 patients 46 to 69 years old (mean age 54) were treated with tunical incision or excision and grafting with small intestine submucosa between March 2002 and July 2005. Average followup was 15 months (range 3 to 43). Patients reported less penile pain with intercourse after surgery. There was no difference in Sexual Health Inventory for Men scores. Preoperatively 12 men (63%) had erectile dysfunction, defined as Sexual Health Inventory for Men less than 21, while 10 (53%) reported postoperative erectile dysfunction. Seven of the 19 patients (37%) had recurrent penile curvature (greater than 10 degrees) and 5 (26%) had recurrent Peyronie's disease plaque. Our complication rate was 37%, including hematoma at the graft site in 5 cases (26%), graft infection in 1 (5%) and Peyronie's disease recurrence requiring plication in 1 (5%).

Conclusions

Small intestine submucosa carries potential for grafting applications because it is easy to use and readily available. Our experience resulted in a 37% complication rate, which exceeds those previously reported with saphenous vein graft repair.
