Purpose: Small intestinal submucosa (SIS) has been described for corporal body grafting in cases of severe penile curvature. We reviewed our experience with a 2-stage repair using corporal body grafting with SIS for proximal hypospadias and severe chordee. Materials and Methods. A retrospective chart review was performed on 12 patients with penoscrotal hypospadias and severe chordee. Corporal grafting was performed with a 4-layer SIS graft (STRATASIS, Cook Biotech, Spencer, Indiana). Patients were evaluated postoperatively with clinic visits after both stages of repair to assess results. Results: Corporal body grafting with SIS was performed in 12 patients between June and December 2001. Average patient age at the time of stage 1 repair was 9 months. Of the 12 patients 8 (66%) had no complications and 10 (83%) have a straight phallus following stage 2 repair. Complications occurred in 4 patients (33%), 2 of which were minor and did not require surgical correction. There were 2 major complications related to the SIS graft, 1 of which required excision of the graft and replacement with a tunica albuginea flap, and the other required 3 dorsal plications to correct residual chordee. Conclusions: Our experience using the 4-layer SIS resulted in 2 major complications requiring surgical correction during stage 2 repair. This rate exceeds the complications reported with either dermal or tunica vaginalis grafts. Currently we have stopped using SIS for corporal grafting.
