D) Other (please specify)
Prosthetic Infections:
Infection rates for inflatable penile prosthesis have been drastically reduced through peri-operative antibiotics,
sterile technique, reduced operative time, and the advent of prosthetics with anti-infection strategies (Coloplast
Hydrophilic Coating; AMS Inhibizone). Documented infection rates are between 1-3%. The next set of questions
are with regard to post-operative inflatable penile prosthesis infections.
