Nerve stimulation (InterStim)

InterStim trial: how it works

How does the InterStim trial work?

Short version

A short procedure places a thin wire near the nerves above the tailbone, connected to a small external device. You keep track of your bladder habits for several days up to a couple of weeks.

A closer look

If your symptoms improve enough, you can choose the long-term implant. If not, the wire is removed.

Getting it checked

If pills haven't fixed your bladder symptoms, ask about an InterStim trial.

Planning the trial

Pickens County patients with overactive bladder or retention can discuss InterStim at our Jasper Clinic. We'll review a bladder diary, past medicines and other treatments, and explain how the trial is set up at our Marietta Clinic & Surgery Center.

How the trial works

A thin temporary lead is placed near the sacral nerve, connected to a small external device. Over the trial days you go about normal life and track symptoms. If bladder control improves enough, the permanent device is placed during a short second procedure. If not, the lead is removed and other options remain.

During the trial, call if

  • The lead site becomes red or drains
  • Fever develops
  • Stimulation feels uncomfortable

Common questions

Common questions

Can I shower during the trial?

Sponge baths are usually advised during the trial, because the temporary lead and its dressing must stay dry. Showers resume once the permanent device site has healed.

What counts as success?

The goal is a clear drop in urgency episodes, leaks or catheterizations in your trial diary. If you reach it, the permanent device is typically the next step.

Jasper, Nelson and Marble Hill residents can reach us at (678) 344-8900.

Keep the bladder diary going through the whole trial and bring it to the follow-up; it's the clearest way to see how much the stimulation helped. Avoid heavy lifting and vigorous activity during the trial so the lead stays in place.

We'll review results together and decide on the next step.

Our Jasper team will answer questions throughout the trial.

Questions are always welcome.
