Percutaneous Tibial Nerve Stimulation — Office-Based Devices
This page covers PTNS hardware and treatment burden. For patient assessment, insertion technique and clinical alternatives, see PTNS procedure.
Available Systems
| System | Hardware |
|---|---|
| Urgent PC — Laborie | External stimulator with a percutaneous needle electrode and surface electrode |
| NURO — Medtronic | External stimulation system with its compatible single-use needle/electrode kit |
Both deliver tibial stimulation without an implant. Use the exact system's instructions for electrode placement, connections and programming; a published protocol does not establish identical hardware or settings for every product.[1][2]
Course and Evidence
A commonly studied induction course is 30 minutes weekly for 12 weeks. In the 220-participant SUmiT sham-controlled trial, 54.5% versus 20.9% reported moderately or markedly improved overall bladder symptoms at 13 weeks. This is a global-improvement outcome, not a percentage of patients made dry.[3]
Maintenance is individualized. STEP enrolled 50 initial SUmiT responders, of whom 29 completed three years; after a taper, the median maintenance frequency was 1.1 treatments per month. This selected-responder study does not establish a fixed interval or durable response for everyone starting PTNS. Discuss ongoing visits, reassessment and the possibility of symptom recurrence.[4]
Eligibility and Precautions
US manufacturer summaries describe OAB-associated urgency, frequency and urge incontinence. They list contraindications including pacemakers/implantable defibrillators, excessive bleeding risk, relevant nerve damage, and pregnancy or planned pregnancy. Avoid treatment through compromised skin and consult the full device instructions. Minor insertion-site bleeding, discomfort and inflammation can occur.[1][2]
The 2024 AUA/SUFU guideline allows shared decisions about minimally invasive therapies without mandatory preceding treatment trials. Statement 25 specifically recommends offering percutaneous tibial stimulation, SNM and/or intradetrusor botulinum toxin after inadequate response or intolerance to behavioral therapy or medication. A rigid “third-line only” description no longer reflects that framework.[5]
Implants and Surface-Electrode Therapy
eCoin, Revi and Altaviva reduce repeat office stimulation visits but introduce implantation, maintenance and device-specific safety requirements. The AUA 2024 implantable-device section does not transfer the PTNS recommendation to these systems.[5]
TTNS uses surface electrodes and can support a home protocol. Its device, regimen, population and evidence differ from percutaneous and implanted stimulation; a shared target nerve does not establish interchangeable efficacy. See the procedure hub for that comparison.
