Percutaneous Tibial Nerve Stimulation
Percutaneous tibial nerve stimulation (PTNS) is office-based retrograde neuromodulation of the sacral plexus through the posterior tibial nerve. It is used for refractory overactive bladder and urgency urinary incontinence when patients prefer a low-risk, non-implantable option or are poor candidates for medication, Intradetrusor OnabotulinumtoxinA, or Sacral Neuromodulation.[1][2]
This page is the canonical tibial-nerve stimulation target for the OAB database, including PTNS and implantable tibial systems. It is intentionally separate from sacral neuromodulation because the procedures, maintenance burden, and device counseling are different.
Technique Snapshot
| Modality | Route | Typical protocol |
|---|---|---|
| PTNS | Needle electrode near the posterior tibial nerve at the medial ankle | Weekly 30-minute treatments for 12 weeks, then maintenance every 3-4 weeks |
| TTNS | Surface electrodes over the tibial nerve | Home or clinic protocols; less invasive but more protocol variability |
| Implantable tibial systems | Subcutaneous tibial-nerve device | Designed to reduce office maintenance burden; device-specific programming and follow-up |
Practical Counseling
- PTNS has a low systemic adverse-effect burden and no implanted sacral generator.
- The tradeoff is repeated visits and ongoing maintenance.
- A poor PTNS response does not necessarily predict SNM failure; the targets and stimulation patterns differ.
- Implantable tibial devices may help maintenance adherence, but their evidence base and device counseling should be kept distinct from classic office PTNS.
