InterStim Therapy

Frequently Asked Questions

Why is this therapy different?

You can try it before you decide, and it’s reversible if you change your mind later. And unlike injections, it doesn’t require self catheterization or repeated treatment visits.

What can this therapy do for me?

It may significantly reduce symptoms in people who have frequent urges to urinate or related frequent leaks or are unable to fully empty their bladder.

Will it cure my condition?

No. It can be effective, but it’s not a cure. If the neurostimulator is turned off or removed, symptoms can return.

What does the stimulation feel like?

Most people describe the stimulation sensation as a tingling, flutter, or vibration in the pelvic area. It should not be painful. Stimulation settings can be adjusted, and sensations will vary from person to person.

Can I have an MRI?

People with an InterStim™ system can have a full-body MRI scan under certain conditions. Your doctor will determine whether you meet those conditions.

Will insurance cover the costs?

Medicare and many private insurance companies cover this therapy. Talk to your doctor to learn more about your insurance coverage.
