Complications Following Transrectal and Transperineal Prostate Biopsy: Results of the ProBE-PC Randomized Clinical Trial

Abstract

PURPOSE: Transrectal prostate biopsy has come under scrutiny due to potential for postbiopsy infections and transperineal prostate biopsy is being offered as the safer alternative. However, there is a lack of randomized comparative studies. Our goal was to directly evaluate infectious and noninfectious complications following the 2 biopsy procedures. MATERIALS AND METHODS: We conducted a prospective, pragmatic, randomized clinical study in men undergoing prostate biopsy. The participants underwent either transrectal or transperineal prostate biopsy in the office under local anesthesia. The primary outcome was a 30-day composite infectious complication rate, comprising of 1 or more components including fever, genitourinary infection, antibiotic prescriptions, office or emergency visits, hospitalization, or sepsis. Secondary outcomes included 30-day composite noninfectious complications (urinary or hemorrhagic). RESULTS: = .79). No participants required hospitalization or other interventions. CONCLUSIONS: Among men undergoing transperineal or transrectal prostate biopsy, we could not demonstrate any difference in the infectious or noninfectious complications. Both biopsy approaches remain clinically viable and safe.
