Intraoperative use of vancomycin paste during penile prosthesis placement: initial outcomes

Area of Science:

• Urology
• Infectious Disease
• Surgical Innovation

Background:

• Penile prosthesis implantation is a standard treatment for erectile dysfunction.
• Infection is a rare but severe complication of penile prosthesis surgery.
• Vancomycin paste offers prolonged local antibiotic exposure, potentially reducing infection risk.

Purpose of the Study:

• To evaluate the safety and efficacy of intraoperative vancomycin paste in preventing infections during penile prosthesis placement.
• To compare infection and complication rates between patients receiving vancomycin paste and a historical control group.

Main Methods:

• A multi-institutional, nonrandomized retrospective study.
• Compared 90 patients receiving primary inflatable penile prosthesis with intraoperative vancomycin paste to 166 historical controls without it.
• Primary outcomes included pump fibrosis, infection, erosion, hematoma, and device malfunction.

Main Results:

• No infections occurred in either the vancomycin paste group (0%) or the control group (0%).
• Overall complication rates were similar: 1.1% in the intervention group (one scrotal hematoma) versus 1.2% in the control group.
• No statistically significant difference in infection or overall complication rates was observed.

Conclusions:

• Intraoperative vancomycin paste appears to be a safe adjunct for penile prosthesis surgery.
• The study did not demonstrate a statistically significant difference in infection prevention.
• Further prospective studies are required to definitively establish the efficacy of vancomycin paste in reducing penile prosthesis infections.
