Antibiotic coating reduces penile prosthesis infection.

Area of Science:

• Urology
• Infectious Diseases
• Biomaterials Science

Background:

• Penile prosthesis implantation is associated with a risk of infection.
• Bacterial adhesion to prosthetic devices is a primary cause of infection.
• Novel strategies are needed to mitigate infection risk in penile prosthesis surgery.

Purpose of the Study:

• To evaluate the efficacy of a new antibiotic-coated penile prosthesis (rifampicin+monocycline) in preventing bacterial adhesion.
• To assess the reduction in penile prosthesis infection rates with the antibiotic-coated device.

Main Methods:

• Retrospective analysis of 152 patients undergoing penile prosthesis implantation (July 1990 - November 2003).
• Comparison between patients receiving antibiotic-coated prostheses (n=58) and non-antibiotic-coated prostheses (n=94).
• Analysis of infection rates and complications requiring surgical intervention.

Main Results:

• No infections were observed in the antibiotic-coated prosthesis group during short- and intermediate-term follow-up.
• Infection requiring surgical intervention occurred in 15 patients (3 reoperations for infection) in the non-antibiotic-coated group.
• Non-infection-related failures occurred in 5 patients in the antibiotic-coated group.

Conclusions:

• Locally delivered antibiotics from prosthesis coating may effectively prevent prosthesis-related infections.
• Antibiotic-coated penile prostheses demonstrate a significant reduction in infection rates.
• This approach offers a valuable adjunct for improving outcomes in penile prosthesis surgery.
