Percutaneous Nerve Eval (PNE) for Fecal Incontinence
What is PNE for Fecal Incontinence?
Percutaneous Nerve Evaluation (PNE) is a test used to see if nerve stimulation therapy can help improve bowel control in people with fecal incontinence (accidental leakage of stool).
The therapy is called sacral neuromodulation and is delivered by the InterStim Therapy System. It works by sending gentle electrical signals to the sacral nerves, which help control the bowels. This therapy can help restore those signals so the body can better control bowel movements.
How does the PNE test work?
During the PNE test:
- A thin temporary wire is placed near the sacral nerves in the lower back and taped in place.
- The wire connects to a small external stimulator that you wear on a belt.
- The device sends mild electrical signals to the nerves.
- You go home and track your symptoms for approximately 7 days.
- After 7 days, you come back to the office where the wires are removed, and your symptom diary is reviewed with you.
If your symptoms improve sufficiently during the test, you may be a candidate for a permanent InterStim implant that is surgically placed under a low back muscle and can provide long-term symptom relief.

Risks & Considerations
As with any medical procedure, there are possible risks. These may include:
- Pain at the Implant Site
- Infection
- Movement of the Wire (Lead)
- Uncomfortable Stimulation
Not everyone is a candidate for this therapy, and results can vary from person to person.
Your doctor will review the potential benefits and risks with you and help determine whether PNE and InterStim therapy are right for you.
