Abstract

OBJECTIVE:

To assess the role of pelvic plexus block (PPB) in reducing pain during transrectal ultrasonography(TRUS)-guided prostate biopsy, compared with the conventional periprostatic nerve block (PNB).

PATIENTS AND METHODS:

A prospective, double-blind observational study was conducted with patients being randomised into three groups. Group-1 (47 patients) received intrarectal local anaesthesia (IRLA) with 10 mL 2% lignocaine jelly along with pelvic plexus block (PPB) with 2.5 mL 2% lignocaine injection bilaterally. Group-2 (46 patients) received IRLA with periprostatic nerve block (PNB). Group-3 (46 patients) received only IRLA without any type of nerve block. The patients were requested to rate the level of pain from 0 to 10 on a visual analogue scale (VAS) at two time points: VAS-1: during biopsy procedure and VAS-2: 30 min after the procedure.

RESULTS:

The mean age of the patients, mean volume of the prostates and mean serum PSA values were comparable among the three groups. The mean pain score during biopsy was significantly less in the PPB group [mean (range) sore of 2.91 (2-4)] compared with the PNB group [mean (range) score of 4 (3-5)], and both these groups were superior to the no nerve block group [mean score of 5.4 (3-7)]. There was no significant difference between the mean pain scores, 30 min after the procedure among the three groups with the mean (range) scores being 2.75 (2-4), 2.83 (2-4) and 2.85 (2-4), respectively.

CONCLUSION:

PPB is superior to conventional periprostatic nerve block (PNB) for pain control during TRUS-guided biopsy and both are in turn superior to no nerve block.
