Percutaneous Nerve Stimulation
Percutaneous Nerve Stimulation (PNS) is used to treat overactive bladder, urinary urgency, and urgency incontinence. The treatment is usually reserved for patients who have failed pelvic floor exercises and medications.
The treatment consists of 12 weekly 30-minute stimulation treatments. An electrical lead device is placed in a nerve near the heel and impulses are sent to the nerve, which travel to the nerves that help control bladder function. The process is referred to as neuromodulation.
Patients typically see a response starting at 5-7 weeks. 60-80% of patients see a satisfactory response in their symptoms.
Side effects of this treatment are usually mild and include:
- Pain, swelling or tingling near the injection site.
- Redness or swelling near the injection site.
- Bruising or bleeding are less common but may occur.
If side effects are intense or worsen over time, please contact your physician.
Certain risks involved with PNS include:
- Wire movement
- Temporary electric shock-like feeling
The device may also stop working. Up to 2/3 of people who have PNS will need another surgery within 5 years to fix the implant or to replace the battery.
