Infectious Adverse Events Following the Placement of a Penile Prosthesis: A Systematic Review.

ABSTRACT

INTRODUCTION: Infection remains a prominent concern following penile implantation. Recognition of the risk factors for infection may help to guide surgeons toward reducing the risk of prosthetic contamination. AIM: To gain a further understanding of infectious adverse events following penile prosthesis, we performed a systematic literature review. METHODS: As part of the 2018 American Urological Association Erectile Dysfunction Clinical Guidelines and with the support of the American Urological Association, we performed a comprehensive review of the PubMed, Embase, and Cochrane databases to search for eligible articles published between January 1, 1965, and July 20, 2016, to identify articles reporting infectious adverse events following prosthesis placement. MAIN OUTCOME MEASURE: The main outcome measure was infectious adverse events following penile prosthesis placement. RESULTS: Ninety-one articles reporting infectious adverse events representing 97 study arms were identified. Prosthetic infection rates ranged from 0% to 24.6% across all series. Inflatable penile prostheses displayed a wider range (0-24.6%) than malleable devices (0-9.1%); the most frequently reported infection rate for inflatable devices was 5% or less. With the advent of device coatings and improved surgical techniques, infectious adverse events have decreased. Infections among diabetic patients also decreased throughout the reviewed body of literature, with the most recent series reporting rates consistent with those of non-diabetic patients. Furthermore, no glycosylated hemoglobin cutoff was found to infer increased or decreased risk of prosthesis infection. CONCLUSION: Overall penile prosthetic infectious adverse events have decreased as surgical techniques have improved and the use of antimicrobial coating has gained in popularity. These advances have demonstrated significant benefits for all patients, particularly diabetic patients who experience infection rates similar to those of non-diabetic patients in recent reports. Further technological advancements for the prevention of biofilm formation is warranted. Mahon J, Dornbier R, Wegrzyn G, et al.
