A Retrospective Comparison of Transrectal and Transperineal Prostate Biopsies: Experience of a Single Surgeon.

Abstract

Background: Transrectal ultrasound-guided prostate biopsy (TRUS) is the gold standard for undertaking prostate biopsy, however, it has been associated with higher rates of post-biopsy sepsis than transperineal prostate biopsy (TP). Objective: To compare complication rates between transrectal prostate biopsy and TP for a single surgeon. Materials and Methods: Data were collected for all prostate biopsies undertaken by a single experienced urologist through his private rooms between February 2012 and March 2018. In total, 693 cases were included (560 individual men) in the final analysis (transrectal = 276 and transperineal = 417). All patients were followed up 2 weeks post-biopsy, and complications were recorded (sepsis, urinary tract infection [UTI], bleeding, and acute urinary retention [AUR]). Results: Complications occurred in 37 cases (transrectal = 3 and transperineal = 34). Sepsis occurred in one case following transrectal biopsy (0.36%) and two cases following TP (0.48%). UTI occurred in two cases following transrectal biopsy (0.72%) and two cases following transperineal (0.48%). Bleeding occurred in one case following TP (0.24%). The most common complication was AUR, which occurred in 28 cases following TP (6.71%). Conclusions: Data from this study compared complication rates for both transperineal and transrectal prostate biopsies in a single-surgeon study.
