What is Sacral Nerve Stimulation?
Also known as InterStim therapy, sacral nerve stimulation delivers mild electrical pulses to the sacral nerves (S2-S4). These nerves control the bladder, bowel, and pelvic floor muscles. By modulating the neural communication between the brain and these organs, normal function can be restored. It is a well-established therapy with over 25 years of clinical use worldwide.
Conditions Treated
Sacral nerve stimulation is clinically proven for a range of pelvic floor and urological conditions:
- Overactive bladder (urge urinary incontinence)
- Non-obstructive urinary retention
- Fecal incontinence
- Chronic pelvic pain
- Interstitial cystitis / painful bladder syndrome
- GynoModulation applications (pioneered by Dr. Ulduz Jafarova at NuRaX)
How InterStim Works
The InterStim system consists of a thin lead and a small neurostimulator that work together to restore normal nerve activity:
- A thin lead is placed near the sacral nerve through a small incision.
- The lead is connected to a small neurostimulator implanted in the upper buttock area.
- The device delivers mild electrical pulses that restore normal nerve activity.
- The stimulation helps the brain and pelvic organs communicate properly.
- Patients can adjust stimulation levels with a handheld programmer.
Two-Stage Evaluation
InterStim therapy follows a proven two-stage approach to ensure the best possible outcomes:
Stage 1 — Test Stimulation:
- A temporary lead is placed near the sacral nerve.
- The patient undergoes a 1-2 week evaluation period at home.
- Symptoms are tracked in a daily diary throughout the test period.
- Success is defined as 50% or greater improvement in symptoms.
Stage 2 — Permanent Implant:
- If the test stimulation is successful, the permanent system is implanted.
- A small neurostimulator is placed in the upper buttock area.
- The procedure takes approximately 1 hour.
- Patients typically return to normal activities within days.
Expected Results
Clinical studies and real-world outcomes demonstrate significant benefits for appropriately selected patients:
- 50-80% improvement in symptoms for most patients
- Significantly reduced urgency and frequency
- Improved quality of life and confidence
- Reversible if needed — the device can be removed at any time
- Long battery life (up to 15 years with rechargeable models)
- MRI-compatible options available
