About Sacral Neuromodulation

Interstim II Hero-wLead

If you’ve tried other treatments for your urinary retention without success, you may want to consider an evaluation of sacral neuromodulation with the InterStim® Therapy. Sacral Neuromodulation, also called sacral nerve stimulation, has been available since 1994 and has been used to treat more than 100,000 people around the world.

What Is It?

The InterStim neurostimulator is a tiny device that is inserted under your skin, usually above your buttocks. It sends mild electrical pulses to the nerves in your back that control the muscles in your bowel, rectum and bladder. The neurostimulator works by stimulating your sacral nerves, helping you regain control of your bladder function. If you have bowel problems as well as your urinary retention, these can be treated at the same time

Verify System

To help discover if InterStim Therapy is right for you, Medtronic has created an evaluation programme. The Evaluation is done with the Verify Evaluation System, which is specifically designed for this part of the treatment to allow your doctor to take the best treatment decision. You and your doctor can try it without making a big commitment.

The evaluation of InterStim Therapy involves placing a thin wire under the skin in your lower back. The wire is connected to a small external neurostimulator, which you wear on a belt. The Verify™ ENS sends mild electrical pulses through the thin wire to your sacral nerves to check if those pulses can get your bladder working the way it should. During the trial assessment, which typically lasts several days, you can continue many of your daily activities with caution.
