Sacral neuromodulation (SNM) is a proven treatment option for bladder control and bowel control. Hundreds of thousands of patients worldwide have received SNM for bladder control and bowel control delivered by the InterStim™ system.†VIEW PRODUCTS
With the InterStim™ system, the implanted neurostimulator and lead electrically stimulate the sacral nerve. This is thought to normalize neural communication between the bladder and brain1 and between the bowel and brain.2 Unlike oral medications that target the muscular component of bladder control, the InterStim system offers control of symptoms through direct modulation of the nerve activity.1 , 2
One key advantage of this therapy is that it can be tested for potential success prior to implantation. The evaluation provides an opportunity to find out whether adequate symptom reduction is achieved in as few as three to seven days. Complications can occur with the evaluation, including tissue damage, infection, and technical problems with the device. Patients should be instructed on operating the programmer and given precautions related to the evaluation.
Restored bladder function defined as ≥50% reduction in dysfunctional voiding symptoms from baseline. Restored bowel function is defined as ≥50% reduction in chronic fecal incontinence episodes.
