Three different anesthesia techniques for a comfortable prostate biopsy

In this paper, we aimed to compare the efficacy of three different anesthesia techniques applied in 90 cases of which transrectal ultrasound (TRUS) -guided prostate biopsies were taken.

Between February 2012 and July 2012, TRUS-guided 16 core biopsies were taken from 90 patients who comply the study criteria. Patients were randomly divided into three groups each of which consists of 30 individuals. Group 1: Was applied periprostatic block anesthesia; Group 2: Was administered intrarectal lidocaine gel; Group 3: Was applied pudendal block. Visual analog scale (VAS) of patients in groups was evaluated.

There was no statistically significant difference between the mean ages, prostate-specific antigen values of three groups. Although pain ratings of Groups 2 and 3 were high, no significant difference was present between each other (P > 0.05). In Groups 1 and 2, the difference between VASs was significant. In the group where periprostatic block was applied, pain ratings were significantly low compared with the other two groups (P = 0.0001).

Enabling pain and discomfort control in patients is very important during TRUS-guided prostate biopsy. In our study, we observed that the periprostatic block enables more comfortable compared with patient groups with intrarectal lidocaine gel and pudendal block and better reduction in pain scores.
