Summary
Penile prosthesis infection rates were 2.0% in this review of inflatable penile prostheses. Risk factors like diabetes or repeat surgery did not significantly alter infection rates, with most infections occurring early.
Area of Science:
- Urology
- Infectious Disease
Background:
- Penile prostheses are implanted to treat erectile dysfunction.
- Infection is a significant complication following penile prosthesis implantation.
Purpose of the Study:
- To determine infection rates and identify risk factors in recipients of three-piece inflatable penile prostheses.
- To analyze the timing and common pathogens associated with penile prosthesis infections.
Main Methods:
- Retrospective review of computer registry records for 491 patients who received three-piece inflatable penile prostheses between April 1986 and March 1999.
- Analysis of bacteriological culture reports from medical records to identify causative organisms.
- Comparison of infection rates between primary and secondary recipients, and between diabetic and non-diabetic patients.
Main Results:
- Overall infection rate was 2.0% (10 out of 491 recipients).
- Infection rates were similar for primary (2.5%) and secondary (1.5%) recipients, and for non-diabetic (2.0%) and diabetic (2.2%) patients; these differences were not statistically significant.
- Eight of the ten infections occurred within 8 weeks of implantation.
- Commonly cultured organisms included E. coli, Proteus mirabilis, Staph. aureus, and Bacteroides.
Conclusions:
- The infection rate for three-piece inflatable penile prostheses is low at 2.0%.
- Diabetes and prior prosthesis implantation are not significant risk factors for infection.
- Early detection and intervention are crucial, as most infections manifest within 8 weeks post-implantation.
