Sacral Nerve Stimulation (InterStim Therapy)
Sacral nerve stimulation is a therapy that addresses the nerve component of urinary control. InterStim Therapy is intended for patients who have failed or could not tolerate more conservative treatments.
About Sacral Nerve Stimulation
Millions of patients experience bladder control problems, including urinary urge incontinence, non-obstructive urinary retention, and significant symptoms of urgency-frequency.
Medtronic offers an innovative therapy for overactive bladder and urinary retention called sacral nerve stimulation (InterStim® Therapy) in patients who have failed or could not tolerate more conservative treatments. The therapy provides urinary control therapy that addresses the nerve component of bladder control problems.1, 2
- Over 75,000 patients have received sacral nerve stimulation worldwide*
- Minimally invasive in-office test
- Over 11 years being FDA approved
- Proven efficacy in patients for whom more conventional therapy has been unsatisfactory 2-9
Indications
Sacral nerve stimulation (InterStim® Therapy) is indicated for patients who haven't had success with urinary control medication, and who suffer from one or more of the following conditions:
- Urinary urge incontinence
- Urinary urgency-frequency
- Non-obstructive urinary retention
Contraindications
Diathermy. Patients who have not demonstrated an appropriate response to test stimulation or are unable to operate the neurostimulator.

Treatment and Diagnosis
How it Treats Overactive Bladder*
Mild electrical pulses stimulate the nerves that provide the most distal common autonomic and somatic nerve supply to the pelvic floor and lower urinary tract. 2, 6
Sacral nerve stimulation offers:
- Effective urinary control1-6
- Proven efficacy in patients for whom more conventional therapy has been unsatisfactory1-6
- Minimally invasive test and implant procedure
*The precise mechanism of action has not been established.
