ABSTRACT

PURPOSE:

This study was designed to compare the effectiveness of intrarectal lidocaine gel versus periprostatic lidocaine injection during TRUS-guided biopsies. MATERIALS AND

METHODS:

From April 2003 to September 2003, 90 men undergoing a transrectal prostate biopsy were randomized into three groups. In group 1, 30 patients intrarectally received 20ml of 2% lidocaine gel; and group 2, 30 patients received 5ml(2.5ml per side) of 2% lidocaine solution injected along each side of the prostate, near the junction of the seminal vesicle and the base of the prostate(along the neurovascular bundles); in group 3, 30 patients received 5ml(2.5ml per side) of normal saline injected along the neurovascular bundles. The pain level after the biopsy was assessed using a 10-point linear visual analog pain scale(VAS). A statistical analysis was performed using the Wilcoxon Rank Sum test, and the results compared.

RESULTS:

Patient who received lidocaine solution injections along the neurovascular bundles (Group 2) had significantly lower VAS scores compared to the control group(mean score 3.56+/-2.13 versus 5.83+/-1.94, p<0.0001), but patients who received intrarectal lidocaine gel did not (mean score 5.46+/-2.70 versus 5.83+/-1.94, p=0.671). Gross hematuria, rectal bleeding and hemospermia occurred in 36(40.0%), 6(6.7%) and 5(5.6%) subjects, respectively. One patient had a vasovagal syncope. No patient reported febrile UTI or urinary retention.

CONCLUSIONS:

Bilateral nerve blockade with local anesthetic is a safe technique that significantly reduces pain during a prostate biopsy. However, in this study, intrarectal lidocaine injection did not reduce the pain compared to the control group during the prostate biopsy.
