title: Distal penile prosthesis extrusion: treatment with distal corporoplasty or Gortex windsock reinforcement.
abstract: Subcutaneous extrusion of penile prosthesis cylinders beneath the glans penis is an unusual but difficult complication of penile prosthesis. Without surgical repair, extrusion, infection, and corporeal fibrosis may ensue. Twenty-eight patients with distal corporeal extrusion were reviewed to identify the optimum treatment outcome for these penile prosthesis complications. Records of 28 men with subcutaneous distal penile prosthesis cylinder extrusion were reviewed. Mean age was 56.2 y. Etiology of erectile dysfunction was diabetes mellitus in 11, vasculogenic in 10, Peyronie's disease in five, radical pelvic surgery in five. Duration of penile prosthesis was 8-72 months (mean 42.6). No patient had penile prosthesis infection or device exposure through the skin. Distal corporoplasty was treated on 18/28 men using cylinder repositioning and direct tunica albuginea repair. Ten men underwent repair using a Gortex windsock. 8/18 corporoplasty and 6/10 windsock patients required glans fixation for treatment of hypermobile glans following cylinder relocation. In two patients with windsock repair, extrusion recurrence occurred 6 and 18 months following surgery and 1/6 had post operative infection requiring prosthesis removal. Mean surgical time for corporoplasty was 52.8 minutes while windsock reconstruction was 89.6 minutes. Distal subcutaneous penile prosthesis cylinder extrusion produces coital pain and predisposes to cylinder exposure and infection. Early repair with or without additional prosthetic materials will return penile prostheses to a normal functioning state. Distal corporoplasty with cylinder repositioning appears to be a simple, low morbidity solution to this difficult dilemma. Outcomes with distal corporoplasty result in better function, less pain, and fewer recurrences than Gortex windsock repair.
