Randomized Controlled Trial Comparative Study Clinical Trial
Unilateral pudendal nerve blockade for relief of all pain during transrectal ultrasound-guided biopsy of the prostate: a randomized, double-blind, placebo-controlled study.
To investigate the efficacy of unilateral pudendal nerve block for the relief of all pain during transrectal ultrasound (TRUS)-guided prostate biopsy. TRUS-guided prostate biopsy is the standard procedure to diagnose or rule out prostate cancer. The pain, attributed to ultrasound probe insertion and the needle punctures into the prostate, inflicted by TRUS-guided prostate biopsy limits its effectiveness. ⋯ Unilateral pudendal nerve blockade was effective in reducing the pain at both biopsy and probe manipulation in our study.
