PENILE PROSTHESIS INSERTION WITH CORPOREAL RECONSTRUCTION WITH SYNTHETIC VASCULAR GRAFT MATERIAL

Difficulty with penile prosthesis insertion may be encountered in patients with severe cavernous scarring or tunica albuginea deficiencies. Eleven patients who underwent penile prosthesis implantation required simultaneous corporeal reconstruction due to prior prosthesis infection and/or erosion in 6, priapism in 2 and Peyronie's disease in 1. One patient underwent prior neophallus construction with a tubularized abdominal wall flap for gender reassignment and 1 had congenitally deficient corporeal bodies. In 4 patients previous additional attempts at prosthesis replacement were unsuccessful. The reconstruction techniques included exposure of the corpora usually through a ventral midline incision and repair with synthetic vascular graft material. Accessory sub-coronal incisions were used when the disease was localized to the distal corpora. Six patients required reconstruction of more than half of the corporeal lengths bilaterally and in 5 smaller portions were repaired. Two patients received a semirigid and 9 an inflatable implant. Mean followup was 46 months (range 5 to 81). One patient required early reexploration for separation of the graft from the tunica and 2 required late surgical revision for distal tip divergence. Healing has been excellent and prosthesis function satisfactory in all patients. Infection, erosion and mechanical failure have not occurred. Penile prosthesis insertion with corporeal reconstruction using synthetic graft material is possible in these cases with acceptable morbidity rates and satisfactory erectile function.
