Summary
Pelvic organ transplant recipients have a higher risk of penile prosthesis complications, particularly with three-piece devices. Non-reservoir prostheses are recommended for these patients to minimize risks.
Area of Science:
- Urology
- Transplant Surgery
- Medical Device Engineering
Background:
- Erectile dysfunction is a common concern for pelvic organ transplant recipients.
- Penile prosthesis implantation is a treatment option for severe erectile dysfunction.
Purpose of the Study:
- To compare complication rates of penile prosthesis implantation in pelvic organ transplant recipients versus non-transplant patients.
- To identify specific complications and risk factors in this patient population.
Main Methods:
- Retrospective analysis of 211 penile prosthesis implantations between 1994 and 2000.
- Comparison of 46 pelvic organ transplant recipients with a control group of 165 non-transplant patients.
- Monitoring for infection, malfunction, autoinflation, and surgical injury.
Main Results:
- Overall complication rate was significantly higher in transplant patients (22%) vs. non-transplant patients (7.9%).
- Infection rates were similar (4.3% vs. 4.2%).
- Malfunction and surgical injury rates were significantly higher in transplant patients, primarily associated with three-piece prostheses and retroperitoneal reservoirs.
Conclusions:
- Penile prosthesis implantation is feasible for pelvic organ transplant recipients with erectile dysfunction.
- Three-piece prostheses with retroperitoneal reservoirs should be avoided due to increased risk of malfunction and injury.
- Prostheses without retroperitoneal reservoirs showed no significant difference in complication rates, making them a safer option.
