InterStim™ systems have been implanted in over 325,000 patients*, and evaluated in more than 1,000 published clinical articles, including long-term (5-year) data for urinary incontinence, retention, and faecal incontinence.1-3VIEW PRODUCTS
With the InterStim™ systems, the implanted neurostimulator and lead electrically stimulate the sacral nerve. This is thought to normalise neural communication between the bladder and brain and between the bowel and brain.4,5 Unlike oral medications that target the muscular component of bladder control, the InterStim™ systems offer control of symptoms through direct modulation of the nerve activity.4,5
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. 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.
The most common adverse events experienced during clinical studies of patients with SNM included pain at implant sites, new pain, lead migration, infection, technical or device problems, adverse change in bowel or voiding function, and undesirable stimulation or sensations. Any of these may require additional surgery or cause the return of symptoms.
