What Is InterStim Therapy?


Detail - The neurostimulator is placed in the upper buttock

InterStim Therapy has been FDA-approved since 1997 for urge incontinence and since 1999 for urinary retention and urgency-frequency. InterStim Therapy is not intended for patients with a urinary blockage.

How It Works 

Sacral neuromodulation works with the sacral nerves, located near the tailbone. The sacral nerves control the bladder and muscles related to urinary function. If the brain and sacral nerves don’t communicate correctly, the nerves can’t tell the bladder to function properly. 

InterStim Therapy modulates the sacral nerves with mild electrical pulses. This helps the brain and the nerves to communicate so the bladder and related muscles can function properly.

InterStim Therapy is a reversible treatment that can be discontinued at any time by turning off or removing the device. 

Sacral neuromodulation may help you resume normal activities, and help you avoid frustrating experiences associated with urinary retention.

Test It Out

After talking with your doctor to see if InterStim therapy is right for you, you may decide to try InterStim Therapy by going through an evaluation. The evaluation generally lasts several days. Before and during the evaluation, you'll be asked to track your symptoms to help determine how well InterStim Therapy works for you.
