To evaluate the results of excising minimal scar tissue in patients undergoing insertion of a penile prosthesis for extensive corporal fibrosis. Twelve patients (mean age 58 years, range 44-73) with extensive corporal fibrosis who underwent the insertion of a penile prosthesis were evaluated. Eleven patients had a defect of varying extent after the insertion of the penile prosthesis, and a polytetrafluoroethylene graft was used to cover the area. All 12 patients tolerated the procedure well and currently have a functioning penile implant. Minimal excision of scar tissue provided better results and fewer complications when compared to other studies which used extensive excision.
