Who is a candidate for InterStim for urinary retention?
At a glance
InterStim may help people who can't fully empty their bladder because the nerve signals aren't working right, not because of a blockage. It's often for those who use a catheter.
Details
A trial comes first. Testing must rule out blockages like an enlarged prostate. Using a catheter for retention?

Advanced Urology on Nerve stimulation (InterStim)
An evaluation in Dallas
Paulding County patients who can't empty fully can begin with Daniel Roberson, PA-C, at our Dallas Clinic. A bladder scan after voiding, a urine test and a review of medicines and health history come first, and urodynamic testing may follow.
Who may benefit
InterStim can help some people whose bladder doesn't squeeze well without a blockage, a pattern called non-obstructive retention. It's less suited to retention caused by an enlarged prostate, where prostate treatment comes first. A trial period shows how well it works, and the permanent device is placed by our urologists in Marietta.
Seek care quickly if
- You can't pass any urine
- Fever or chills develop
- Leg weakness or numbness appears along with back pain
Common questions
Common questions
Will I still need to catheterize?
Many people are able to cut back or stop, though some keep catheterizing occasionally; the trial helps show what to expect.
Is it MRI-compatible?
Many newer systems allow certain MRI scans; we'll go over the details for your device.
Residents of Dallas, Hiram and Powder Springs can phone (678) 344-8900 to arrange an evaluation, and many follow-up checks can happen back in Dallas.
Keeping a diary of catheter volumes and voids during the trial helps everyone see how much the device is helping before the decision to move ahead.
We'll review that diary with you at the end of the trial and decide together on the next step.
