Definition

Percutaneous tibial nerve stimulation (PTNS) uses a gentle electrical pulse to stimulate a nerve. This nerve leaves the low back and passes down the leg. It splits near the knee. One part passes down the knee and ends just inside the heel. This is the part that is treated.

Reasons for Procedure

PTNS is used to treat an overactive bladder in women. The signal starts near the heel. It travels up the nerve to a patch of nerves near the spine. The signal stimulates nerves in this patch including nerves that control the bladder. The signals then help the bladder muscles relax.

Over time these signals can retrain the bladder to relax on its own. It will stop or lessen the symptoms of overactive bladder. PTNS may be used if other treatments have not been helpful.

Possible Complications

Problems from the procedure are rare. All procedures have some risk. The care team will discuss possible problems such as:

• Muscle cramps in the leg, foot, or toes
• Tingling in the leg
• Lightheadedness or fainting when needle is inserted
• Treatment does not work as expected

PTNS is not recommended in people with:

• Pacemaker or implanted defibrillator
• Bleeding problems
• Nerve damage that may get worse with treatment
• Pregnancy or plan to be pregnant

What to Expect

Call Your Doctor

Call your doctor if any of these occur:

• Urinary symptoms worsen
• Cramping, tingling, or other symptoms that last longer than you expect
• Fall or injury due to nerve problems
• Signs of infection at the needle site, such as bleeding, warmth, redness, or leaking fluid
• General signs of infection, including fever and chills

If you think you have an emergency, call for emergency medical services right away.
