Apical peri-prostatic nerve block versus intra-rectal xylocaine gel for trans- rectal ultrasound guided prostate biopsy among Nigerian patients: A prospective randomized study.

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.
