ABSTRACT

Introduction.  A clear set of guidelines has not been defined in the use of antibiotics in penile prosthesis implantation.

Aim.  We surveyed urologists throughout the United States to determine current practice patterns regarding antibiotic use in primary and revision penile prosthesis surgery.

Methods.  Fifty-two Sexual Medicine Society of North America (SMS) member urologist and 164 non-SMS member urologist responses were obtained.

Main Outcome Measures.  The survey contained 10 questions regarding antibiotic selection for primary and revision inflatable penile prosthesis (IPP) implantation.

Results.  One hundred percent of responders in both groups utilize intraoperative antibiotics, most commonly vancomycin and gentamicin in both groups. Of SMS members, 94% prescribed postoperative home oral antibiotics in contrast to 88% of non-SMS members (P = 0.3). Among SMS members, the most common antibiotic prescribed postoperatively was levofloxacin 500 mg daily while among non-SMS members, the most common antibiotic postoperatively was cephalexin 500 mg 2–4 times daily. Of SMS members, antibiotic irrigation intraoperatively occurred with 100% and with 92% of non-SMS members (P = 0.04). Thirty-seven percent SMS physicians and 15% non-SMS physicians made modifications of intraoperative and postoperative antibiotics for high-risk patients (P = 0.001). In the circumstance of revision of a clinically noninfected IPP, 23% SMS and 16% non-SMS member physicians utilized additional antibiotics/treatment (P = 0.3). Sixteen of those surveyed admitted that they had been approached by their institution about their antibiotic use and asked to change. In the past 5 years, 29% surveyed have changed their practice patterns in antibiotic use.

Conclusions.  There is significant difference between practice patterns of SMS and non-SMS urologists in terms of antibiotic irrigation usage, modifications for high-risk patients, and consensus about the importance of antibiotic use with Coloplast Titan implant (Coloplast, Minneapolis, MN, USA). A significant lack of uniformity exists among urologists performing prosthetic surgery with regard to antibiotic protocols. A standard set of guidelines may prove useful to implanters.
