What is Sacral Nerve Stimulation?

Implantable neuromodulation device stimulates sacral nerve to restore bowel control. Non-destructive, reversible treatment for fecal incontinence. Success rate 80-90%. Excellent outcomes without bowel resection or sphincter repair.

Indications

  • Fecal incontinence (moderate to severe)
  • Failed conservative therapy
  • Failed sphincter surgery
  • Neuropathic incontinence

Procedure Stages

Stage 1: Test Phase (PNE)

Temporary percutaneous lead placement. Trial stimulation for 2-3 weeks. If >50% improvement, proceed to permanent implant.

Stage 2: Permanent Implant

Surgical placement of sacral nerve lead. Implantable pulse generator under skin. Device programmable for optimal continence control.

Benefits & Recovery

Non-destructive, reversible, adjustable. Minimal downtime. Patient control via external programmer. Success rate 80-90%. Significant quality of life improvement. Allows normal social activities and travel.

What is sacral nerve stimulation?

Sacral nerve stimulation (SNS), also called sacral neuromodulation, is a treatment for faecal incontinence and some bladder problems. A thin electrode is placed near the sacral nerves at the base of the spine and connected to a small battery-powered device placed under the skin of the buttock. Mild electrical pulses help the nerves and muscles that control the bowel work better.

Who may benefit

  • People with faecal incontinence that has not improved with diet changes, medicines, pelvic floor exercises and biofeedback
  • Patients with weak but intact sphincter muscles
  • Some patients with a sphincter defect who are not suitable for, or did not benefit from, repair

Two-stage treatment

  1. Test phase: a temporary or tined electrode is placed through a needle, usually under local anaesthesia with sedation, and connected to an external stimulator for about two to three weeks. You keep a bowel diary during this time.
  2. Permanent implant: if the test shows a clear improvement, usually at least a 50 percent reduction in leakage episodes, the small stimulator is implanted under the skin in a short procedure.

Living with the device

The stimulation is usually not felt or is felt as a mild tingling. You will receive a hand-held programmer to adjust settings within limits set by your doctor. The battery lasts several years depending on the device and settings, and is replaced in a minor procedure. Some devices have restrictions on MRI scans, so always tell doctors you have an implant.

Possible risks

Risks include pain at the implant site, infection, movement of the electrode, and loss of effect over time that may need reprogramming or revision.

Frequently asked questions

Does sacral nerve stimulation hurt?

The procedures are done with anaesthesia, and the stimulation itself is usually comfortable. Some people feel a gentle tingling.

How do I know it will work for me?

The test phase shows whether you are likely to benefit before the permanent device is placed.

Can it be removed?

Yes. The device can be switched off or removed if needed.
