Shocking pain away: TENS device tested for prostate biopsy discomfort
NCT ID NCT07331246
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a TENS device, which uses mild electrical pulses, can reduce pain during a prostate biopsy. 84 men were randomly assigned to receive TENS plus local anesthetic, a sham TENS device plus local anesthetic, or local anesthetic alone. Participants reported their pain levels at several points during the procedure. The goal is to find a simple, non-drug way to make biopsies more comfortable.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcutaneous electrical nerve stimulation (TENS) device
- What this could lead to
- If it works, TENS could offer a simple, drug-free way to reduce pain during prostate biopsies.
- What could go wrong
- This is a small, single-center exploratory study. The results may not apply to all patients, and TENS might not provide meaningful pain relief.

Inclusion Criteria: * Suspicious lesions on multiparametric MRI, classified as PI-RADS score ≥ 3 * The indication for mpMRI was based on the presence of at least one of the following: * Elevated serum prostate-specific antigen (PSA) levels * Abnormal digital rectal examination (DRE) Exclusion Criteria: * Prior treatment of prostate cancer * Contraindications to TENS, including: * Cutaneous damage or dermatologic conditions at the TENS application sites * Presence of cardiac pacemakers or automatic implantable cardioverter-defibrillators (AICDs) * Uncontrolled cardiac arrhythmias or congestive heart failure * History of epilepsy or seizure disorders * Metal implants near the site of stimulation * Malignancy at or near the site of stimulation * Contraindications to transperineal biopsy, including: * Active urinary tract infection * Bleeding disorders or ongoing anticoagulant therapy * Anatomical abnormalities that prevent safe access to the prostate * Known allergy or intolerance to local anesthetics or biopsy-related materials * Severe comorbidities or unstable medical conditions that could compromise procedural safety * Inability to provide informed consent or refusal to sign the consent form
