Aims: This study compared the analgesic effect of apical peri-prostatic block with that of intra-rectal xylocaine gel for trans-rectal ultrasound guided prostate biopsy (TRUS-PBx) in Nigeria. Methods: This is a prospective randomized comparative study carried out over one year in University of Benin Teaching Hospital, Edo State, Nigeria. The participants were randomized into two groups; Group A had 10 mls of intra-rectal xylocaine gel instillation while Group B had apical infiltration of 10 mls of 1% xylocaine all before TRUS-PBx. Result: There was a statistically significant difference in the mean pain score during and one hour after TRUS-PBx between Group A and Group B of the study population respectively (p < 0.0001). Those that had intra-rectal xylocaine gel (Group A) had more pain during and after biopsy. There was no difference in the mean pain score during probe insertion between the two groups (p = 0.952). Conclusion: This study demonstrated the superiority of apical peri-prostatic nerve block over intra rectal xylocaine gel instillation during TRUS-PBx with respect to its anesthetic efficacy. Therefore, centers providing TRUS-PBx in Nigeria should consider apical peri-prostatic nerve block as their mode of anesthesia for the procedure due to its efficacy and high safety profile.
