ABSTRACT
PURPOSE:
During transrectal ultrasound guided prostate biopsy, 65% to 90% of patients reportedly have discomfort. We compared the anesthetic effects of a periprostatic injection of lidocaine under ultrasound guidance with the effects of a rectal instillation of lidocaine gel before the transrectal ultrasound guided prostate biopsy. MATERIALS ANDMETHODS:
A prospective randomized double-blind study was performed in 72 patients requiring a systematic biopsy of the prostate. Patients were randomized into two groups according to the method of anesthetic delivery that was used. Group 1 consisted of 37 patients who intrarectally received 10 ml of 2% lidocaine gel 10 minutes before biopsy, and 5 ml of normal saline was injected into the periprostatic nerve plexus just before biopsy under ultrasound guidance using an 18 gauge 16 cm needle on each side. Group 2 consisted of 35 patients who received 10 ml of sterile gel without lidocaine and a 5 ml 1% lidocaine injection using the same method as group 1. The pain score was assessed using a visual analogue scale immediately after biopsy.RESULTS:
There was a statistical difference in the mean pain score between the two groups (5.1+/-1.7 in group 1 versus 3.3+/-1.5 in group 2) (p<0.001), but The complication rates were not significantly different.CONCLUSIONS:
We believe that performing the transrectal ultrasound guided prostatic nerve blockade before biopsy significantly diminishes the discomfort associated with the procedure, which, in turn, improves patient tolerance more so than rectal instillation of lidocaine gel. In addition, this procedure is a safe, simple, and rapid technique that should be considered in all patients undergoing transrectal ultrasound guided prostate biopsy.
