Percutaneous tibial nerve stimulation is a minimally invasive, drug-free option for treating the symptoms of overactive bladder. The goal of this procedure is to modify signals from the sacral nerves (S3) to help stabilize bladder function, and allow patients to regain bladder control. The sacral nerves are connected to the bladder, and extend down the leg to the tibial nerve near the ankle.
The PTNS procedure involves placing a thin, needle electrode into the tibial nerve near the ankle. Over the course of 30 minutes, this electrode delivers mild impulses into the nerve. For optimal results, PTNS is given once a week for 12 consecutive weeks.
