Overview
Tibial neuromodulation treats overactive bladder by stimulating the tibial nerve near the ankle. The tibial nerve connects to the sacral nerves that help control the bladder.
In percutaneous tibial nerve stimulation (PTNS), a fine needle electrode is placed near the ankle for about 30 minutes per session, usually weekly for 12 weeks followed by maintenance sessions. Implantable tibial devices are also available.

How it works
A thin needle electrode near the inner ankle is connected to a small stimulator. Mild electrical pulses travel along the tibial nerve to the sacral nerve plexus, which helps regulate bladder function.
