ABSTRACT
PURPOSE:
To assess the analgesic efficacy of intrarectal lidocaine gel instillation prior to periprostatic nerve block during transrectal, ultrasound-guided prostate biopsies. MATERIALS andMETHODS:
Between March 2004 and October 2004, 203 consecutive patients for prostate biopsies were randomized into two groups. In 90 patients of group A, 10ml of 2% lidocaine gel was instilled intrarectally 10 minutes prior to periprostatic neurovascular bundle block, while 113 patients of group B received only periprostatic neurovascular bundle block without lidocaine gel instillation. Pain was assessed with the visual analogue pain scale, during periprostatic neurovascular bundle block (VAS 1), during the biopsy procedures (VAS 2) and 20 minutes after the procedure (VAS 3). The difference in VAS scores between patients in the two groups was evaluated with the unpaired t-test, with p 0.05) or at after 20 minutes after the procedure (VAS 3, 0.9778 versus 1.257, p > 0.05).CONCLUSION:
Intrarectal instillation of lidocaine gel leads to significant additional analgesic efficacy during the biopsy procedure. It is a simple, safe and rapid technique that should be considered in all patients undergoing TRUS guided prostate biopsy.
