Acupuncture for Analgesia in Transperineal Prostate Biopsy: A Randomized Controlled Trial

Insertion of sterile, single-use needles at specific acupuncture points (LI4, PC6, ST36, SP6) for 20 minutes with manual stimulation, administered 30 minutes before the biopsy by a licensed acupuncturist.

Superficial needle insertion at non-acupuncture points without stimulation, administered 30 minutes before the biopsy, mimicking the acupuncture procedure without therapeutic intent.
