Summary
This study evaluated the Mentor two-piece inflatable penile prosthesis in 50 patients. While 86% reported satisfaction, the 28% complication rate, including leaks and infections, was higher than in short-term studies.
Area of Science:
- Urology
- Medical Devices
- Implantable Prosthetics
Background:
- The Mentor two-piece inflatable penile prosthesis is used for erectile dysfunction treatment.
- Long-term outcomes and complication rates require thorough investigation.
Purpose of the Study:
- To assess the long-term efficacy and complication profile of the Mentor two-piece inflatable penile prosthesis.
- To determine patient satisfaction rates with this device over an extended follow-up period.
Main Methods:
- A retrospective analysis of 50 patients who received Mentor two-piece inflatable penile prostheses between October 1987 and June 1993.
- Mean follow-up duration of 52.18 months (range: 6-72 months).
- Documentation of all device-related complications, reasons for removal, and patient satisfaction.
Main Results:
- An overall complication rate of 28% was observed, with reasons including fluid leaks (2%), loss of rigidity (14%), infection (4%), and pump erosion (6%).
- Loss of rigidity was attributed to tunica albuginea stretching, not fully compensated by the device's fluid capacity.
- Despite complications, 92% of prostheses were functional at review, with an 86% overall patient satisfaction rate (72% fully satisfied, 14% partially satisfied).
Conclusions:
- The Mentor two-piece inflatable penile prosthesis demonstrates a high long-term functional rate and patient satisfaction.
- However, the observed 28% complication rate in this long-term series is notably higher than previously reported short-term follow-ups, suggesting potential durability concerns.
