The goal of this clinical trial is to learn whether transcutaneous electrical nerve stimulation (TENS) can reduce pain during transperineal prostate biopsy in adult male patients. It will also assess the safety and tolerability of using TENS in this setting. The main questions it aims to answer are:
Does TENS lower patient-reported pain during local anesthesia and prostate biopsy sampling?
Are there any side effects or complications associated with using TENS during the procedure?
Researchers will compare TENS to a placebo (sham TENS with no active stimulation) and to standard care (local anesthesia alone).
Participants will:
Be randomly assigned to receive either TENS + local anesthesia, sham TENS + local anesthesia, or local anesthesia alone
Undergo a standard transperineal prostate biopsy guided by MRI-ultrasound fusion
Report their pain levels during four specific stages of the procedure
Attend a follow-up visit 3-4 weeks after the biopsy to review results and assess for any side effects
