Objective: To compare efficacy between heated intrarectal local anesthesia (HIRLA) and periprostatic nerve block (PNB) with respect to pain reduction during transrectal ultrasound-guided prostate biopsy (TRUS-Bx).
Materials and Methods: A prospective randomized trial including 60 participants scheduled for TRUS-Bx from July to December 2024. Participants were assigned to a group using heated intrarectal local anesthesia with 10 ml 40 C 2% lidocaine gel (n=30) or PNB (n=30). Primary outcome was the level of pain as measured by pain score using a visual analog scale (VAS) during TRUS-Bx. The secondary outcome was complications which occurred during and after the procedure.
Results: The level of pain in the HIRLA group was greater in comparison to PNB (4.03±1.85 versus 2.57±1.68; p=0.002). No differences in complications were observed between the two groups.
Conclusion: PNB provides more effective pain reduction in comparison to HIRLA during TRUS-Bx.
