InterStim therapy uses a small device to send mild electrical pulses to a nerve located in the lower back (just above the tailbone). This nerve, called the sacral nerve, influences the bladder and surrounding muscles that manage urinary function. It also influences the bowel and it’s connection to the brain. The electrical stimulation may eliminate or reduce certain bladder control or bowel control symptoms in some people.

InterStim neurostimulation is designed for patients who will benefit from a smaller implanted device, and those who experience symptom control with low to moderate stimulation. We place the InterStim system surgically under the skin. We use it to treat urinary retention and other symptoms of an overactive bladder, including urinary urge incontinence and symptoms of urgency-frequency in combination, especially in patients who cannot tolerate more conservative treatments.

InterStim therapy can also be used for bowel control in the treatment of chronic fecal incontinence in patients who have not been helped by conservative treatments.

What our patients say

Procedure went well. Staff was very friendly and concerned with any pain levels and care going forward. Doctor was very professional and described everything in detail before it happened.


Entire staff friendly and professional. Dr. Modder was patient and explained every step of the procedure. Results were explained. All my questions were answered. I felt comfortable that I was putting my health in good hands.


Going to a urologist can be a frightening experience. Dr. Vlach has always answered my questions with understandable responses. I left the visit with a sense of relief but also a dreaded appointment for next year. I trust Dr. Vlach. The staff are always professional but also very pleasant.
