Efficacy and safety of a combined anesthetic technique for transrectal prostate biopsy: a single center, prospective, randomized study

Abstract

A transrectal ultrasound-guided (TRUS) biopsy is the gold standard for diagnosis of prostatic neoplasia. This exam is associated with pain and discomfort, and numerous methods of analgesia during this procedure have been described. There is still no consensus among urologists about the pain control technique that should be performed, even though the periprostatic basal nerve block is the most studied technique. The main objective of this study is to evaluate the benefit of adding local periapical prostatic anesthesia to the traditional periprostatic basal nerve block during TRUS biopsy.
