[ Comparison of two methods of local anaesthesia prior to transrectal ultrasound-guided prostate biopsies ] . OBJECTIVE To compare the analgesic efficacy of rectal administration of Lidocaïne gel with Lidocaïne periprostatic infiltration prior to transrectal ultrasound-guided prostate biopsies . MATERIAL AND METHODS Between July 2002 and July 2003 , candidates to prostate biopsies were randomised into two groups . In group 1 , 15 ml 2 % Lidocaïne gel was administered intra-rectally 10 minutes prior to biopsies and patients included in group 2 received 10 ml of 1 % Lidocaïne in two périprostatique equivalent injections , 4 minutes prior to prostate biopsies . Pain was assessed with a Visual Analog Scale , during anaesthesia ( VAS 1 ) , during the biopsies procedure ( VAS 2 ) and 30 minutes after them ( VAS 3 ) . RESULTS 308 patients were included in this trial with 156 patients in group 1 and 152 in group 2 . Group 1 experienced statistically less pain for VAS 1 ( 0.1 versus 1.4 , p < 0.0001 ) and VAS 3 ( 0.8 versus 1.4 , p < 0.001 ) but no significative difference could be demonstrated for VAS 2 ( 1.8 versus 2.0 ) . No major complication was noted . CONCLUSION Rectal administration of Lidocaïne gel and infiltration of Lidocaïne lead to a comparable level of anaesthesia during prostatic biopsies procedure . However , the Lidocaïne gel , being both safe and simple , tends to maintain a better comfort of the patient 30 minutes after the end of the biopsies .
