Randomized Controlled TrialLidocaine-prilocaine administration during transrectal ultrasound-guided prostatic biopsy: a randomized, single-blind, placebo-controlled trial.
As many as 96% of patients report some kind of discomfort/pain during transrectal ultrasonography (TRUS)-guided prostate biopsy, and when pain is severe, it may be necessary to decrease the planned number of biopsies or interrupt the procedure. Various modalities have been recommended to alleviate the pain, but reports on efficacy are contradictory. We assessed the possible benefit of intrarectal and perianal lidocaine-prilocaine (EMLA) cream. ⋯ In patients with high tolerance for simple TRUS, needle trauma does not significantly alter tolerability, and anesthetic provides little benefit for prostatic biopsy. However, the opposite is true in patients presenting moderate to significant pain/discomfort at TRUS, who may benefit from intrarectal/anal administration of EMLA during prostate biopsy.
