Our aim was to determine if the AUA-recommended prophylaxis (vancomycin + gentamicin alone) for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard regimens.We performed a multicenter, retrospective study of patients undergoing primary inflatable penile prosthesis surgery. Patients were divided into those receiving vancomycin + gentamicin alone and those receiving any other regimen. A Cox proportional-hazards model was constructed adjusted for major predictors. A subgroup analysis to identify the appropriate dosage of gentamicin was also performed.A total of 4,161 patients underwent primary inflatable penile prosthesis placement (2,411 received vancomycin + gentamicin alone and 1,750 received other regimens). The infection rate was similar between groups, 1% vs 1.2% for standard vs nonstandard prophylaxis. In the multivariable analysis, vancomycin + gentamicin (HR: 2.7, 95% CI: 1.4 to 5.4,Vancomycin + gentamicin alone for antibiotic prophylaxis for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard antibiotic regimens while antifungal use is associated with lower infection risk. A critical review of the recommended antimicrobial prophylactic regimens is needed. Prospective research is needed to further elucidate best practices in inflatable penile prosthesis antimicrobial prophylaxis.
