minocycline and Erectile-Dysfunction

Although some studies suggest that most infections associated with inflatable penile prosthesis implantation develop within year 1 after surgery, device related infections have been reported 5 years after implantation or later and the infection risk with time is not well characterized. We previously reported a statistically significantly lower infection rate for original inflatable penile prostheses impregnated with antibiotic treatment with minocycline and rifampin vs nonimpregnated inflatable penile prostheses at 1-year followup. Long-term data are now available on infection revision after initial implantation of antibiotic impregnated vs nonimpregnated prostheses.. We retrospectively reviewed patient information forms voluntarily filed with the manufacturer after the initial implantation of more than 39,000 inflatable penile prostheses to compare the revision rate due to infection for antibiotic impregnated vs nonimpregnated implants between May 1, 2001 and December 31, 2008. Life table analysis was used to evaluate device survival from revision surgery.. On life table survival analysis initial revision events due to infection were significantly less common in the impregnated vs the nonimpregnated group (log rank p <0.0001). At up to 7.7 years of followup 1.1% of 35,737 vs 2.5% of 3,268 men with impregnated vs nonimpregnated implants underwent initial revision due to infection.. To our knowledge this long-term outcome analysis provides the first substantial clinical evidence of a decrease in costly infection related revision using an antibiotic impregnated inflatable penile prosthesis.
