OBJECTIVE

To examine the effectiveness of the longer acting agent bupivacaine in providing periprostatic anaesthesia during transrectal ultrasonography (TRUS)-guided biopsy, as the periprostatic injection of lidocaine has been shown to significantly alleviate the pain of this procedure.

PATIENTS AND METHODS

Seventy-five patients were randomized to receive a periprostatic injection with either bupivacaine, a lidocaine/bupivacaine (1/1) combination, or no local anaesthesia. Immediately before biopsy 5 mL of the anaesthetic was injected under TRUS guidance into the periprostatic nerves bilaterally. After taking a 10-core biopsy the patients were given a visual analogue scale (VAS; 0–10) to assess their pain during the procedure.

RESULTS

The mean VAS scores were 2.04 in the bupivacaine group and 4.46 in the control (no local anaesthetic) group (P < 0.001).

CONCLUSIONS

Bupivicaine provides significant, immediate periprostatic anaesthesia for TRUS biopsy.
