Objective Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is a standard diagnostic modality for detecting prostate cancer (PCa). Pain during biopsy is the most important problem that still needs a solution. The purpose of this study was to compare 3 pain control techniques and to investigate the relationship between the level of pain and histopathological findings. Materials and Methods 139 patients underwent prostate biopsy utilizing 3 analgesic techniques; 1- using lidocain gel (group 1), 2- pethidine+diazepam (group 2) and 3- periprostatic nerve block (group 3). Pain level, the tolerability and repetition of the procedure were questioned. The pathological findings were recorded. Results There was a statistically significant difference between group 1 and the others with regard to tolerability and repeating the procedure. The pain score during biopsy in group 1 was greater than in the other groups and those in group 2 was higher than in group 3. The mean pain score during probe insertion in group 2 was lower than in groups 1 and 3. The mean pain score taken during the biopsy was higher than that during probe insertion in group 2. However, the mean pain score during probeinsertion in group 3 was not different from that in group 1. There was no significant difference in pathological results between group 1 and groups 2 and 3. Pain scores in patients with chronic prostatitis were statistically higher than those in patients with benign prostatic hyperplasia (BPH) and Pca in groups 2 and 3 (p<0.05). Conclusion Periprostatic nerve block is superior to the others. However, it is not better than pethidine plus diazepam during rectal probe insertion. In the presence of chronic prostatitis, pain scores can increase regardless of the pain control method.
