Objective:
To evaluate the outcome of penile prosthesis surgery for different types of prosthesis.
Patients And Methods:
The notes of 447 men who had 504 penile prosthesis implanted between August 1975 and December 2000 were evaluated. Of the prostheses inserted, 393 were malleable, 81 were three-piece inflatable and 30 were self-contained hydraulic prostheses. The mean (range) age of the men was 52 (21-78) years; 404 men had primary implants and 43 had revision surgery after operations at other institutions. The mean follow-up was 50 (1-297) months.
Results:
Of the 447 men, 22 were lost to follow-up immediately after surgery. The most serious postoperative complications were infection (8%) and erosion (5%), which was more common in diabetic patients (10%) and after pelvic trauma with a urethral injury (21%). Of 482 prostheses, 21 failed mechanically (4%) and revision surgery was needed for 5% of the prostheses inserted (24/482). Overall, 89% (377/425) of men could have sexual intercourse and 344 (81%) were satisfied with the results.
Conclusions:
Of the men implanted with a penile prosthesis, 81% were satisfied with the outcome and an even higher proportion were satisfied with the inflatable prostheses. Dissatisfaction was mainly due to complications that resulted in removal of the prosthesis.
