Sacral Nerve Stimulation (SNS) is neuro-electrical stimulation of the sacral nerves that supply the anus and rectum.
Sacral Nerve Stimulation (SNS) for Faecal Incontinence
Faecal incontinence can significantly affect quality of life, confidence, and independence. Sacral Nerve Stimulation (SNS) is a well-established treatment option for people whose symptoms have not improved with conservative treatments such as dietary changes, medications, pelvic floor exercises, or biofeedback.
At our centre, SNS is performed by experienced specialist colorectal surgeons as part of a comprehensive bowel care service.
Proven Effectiveness
Strong clinical evidence shows that SNS is effective for many people with faecal incontinence.
-
Most patients experience a significant reduction in bowel leakage
-
Many patients achieve good or complete bowel control
-
Improvements are often noticed within weeks of starting stimulation
-
Patients commonly report improved quality of life, including greater confidence and social freedom
Strong Clinical Evidence
SNS has been extensively studied and used worldwide.
-
Large clinical studies and reviews consistently show that the majority of patients benefit
-
Research confirms that symptoms return if stimulation is switched off, demonstrating that improvements are due to SNS itself
-
SNS is effective in a wide range of patients, including those with muscle weakness or nerve-related bowel problems
Long-Term Benefits
SNS can provide durable, long-lasting results.
-
Many patients maintain improvement for several years
-
Some patients may require occasional adjustments, battery replacement, or minor procedures over time
-
Overall, long-term studies show that benefits are usually sustained
Trial Stimulation Before Permanent Implant
To ensure the best outcomes, SNS treatment usually begins with a temporary trial phase.
-
A temporary wire is placed to test how well SNS works for you
-
You will use the stimulator at home for a short period and record your symptoms
-
Only patients who show clear improvement proceed to permanent implantation
-
This careful selection process increases success and avoids unnecessary surgery
