Pain during transrectal ultrasonography guided prostate biopsy: a randomized prospective trial comparing periprostatic infiltration with lidocaine with the intrarectal instillation of lidocaine-prilocain cream.
Prostate biopsy is usually performed without anesthesia. We evaluated the patient's perception of pain/discomfort experienced during the procedure in terms of the type of anesthesia used: periprostatic infiltration with 2% lidocaine, or intrarectal instillation of lidocaine-prilocain cream. A total of 198 patients were divided into three groups: group 1 (control group, n=40) received sonographic gel intrarectally prior to biopsy, group 2 (n=75) were given intrarectal instillation of lidocaine-prilocain cream, and group 3 (n=80) received periprostatic anesthesia by injecting 10 ml of 2% lidocaine. Pain after each biopsy was assessed using an 11-point linear visual analog pain scale. The mean pain scores were 5.1 in group 1, 4.8 in group 2, and 2.5 in group 3, resulting in a significant difference between group 3 and both groups 1 and 2, but not between groups 1 and 2. The incidence of biopsy-related adverse events did not differ among groups. Transrectal ultrasonographic guided periprostatic anesthesia is superior to intarectal instillation of lidocaine-prilocain cream.
