Application of human amniotic membrane in canine penile tunica albuginea defect: first step toward an innovating new method for treatment of Peyronie's disease.

| Abstract | PURPOSES: To evaluate the efficacy of human amniotic membrane (AM) grafting in the canine penile tunica albuginea defect; we developed an animal model as the first step toward an innovating new method for the treatment of Peyronie's disease, penile cancers, and congenital deformities of the penis. MATERIAL AND METHODS: From August to September 2011, ten healthy male dogs were selected. A rhomboid incision about 3 x 2 cm over the tunica albuginea and its overlying squamous epithelium was made and then excised. The amniotic membrane was folded twice on itself and grafted on the defect. After 8 weeks, artificial erection was made for 5 dogs and for the other 5 dogs after 12 weeks. After artificial erection, partial penectomy was done and histopathological evaluation was performed on the grafts. RESULTS: Artificial erection performed successfully in all of the dogs. No infection or any other complication was seen. Histopathological examination showed complete re-epithelialization with squamous epithelium and collagen fiber deposition. Also, no dysplasia was seen. CONCLUSIONS: The amniotic membrane can be used as a suitable substitution for tunica albuginea. It is safe, inexpensive, biodegradable, and available and may be used for the treatment of Peyronie ' s disease, penile cancers, congenital penile deformities, and penile reconstructive surgery.
