⚡ Sacral Nerve Stimulation (SNS): A Therapy for Bladder and Bowel Control Disorders
HOOK
When the nerves that help control the bladder or bowel do not communicate properly, everyday activities can become difficult and unpredictable. Sacral Nerve Stimulation (SNS), also called sacral neuromodulation, is a medical therapy that uses mild electrical impulses to help regulate nerve signals involved in bladder and bowel function.
HISTORY / OVERVIEW
Sacral nerve stimulation was developed as a treatment for certain urinary and bowel disorders that do not respond adequately to conservative therapies. The treatment targets the sacral nerves, which play an important role in controlling the bladder, bowel, and pelvic floor.
COMMON CONDITIONS TREATED
Overactive bladder with urgency and frequency
Urinary urge incontinence
Non-obstructive urinary retention
Fecal incontinence (loss of bowel control)
Selected cases of bowel dysfunction in appropriate patients
HOW SNS WORKS
The SNS process
A small lead (thin wire) is placed near the sacral nerves in the lower back.
A pulse generator sends mild electrical impulses to these nerves.
The stimulation helps modulate abnormal nerve signaling related to bladder or bowel control.
Many patients first undergo a trial period to see whether symptoms improve before a permanent device is implanted.
KEY FEATURES
Minimally invasive option
Compared with some major surgeries.
Adjustable stimulation
Settings can be customized for the individual.
Long-term therapy
For selected patients.
Reversible treatment
The device can usually be adjusted or removed if needed.
POTENTIAL BENEFITS
Why patients may consider SNS
May reduce urinary urgency and frequency
May decrease episodes of urinary or fecal incontinence
May improve bladder emptying in selected patients with urinary retention
Can improve quality of life for appropriate candidates
Offers an alternative when medications or behavioral therapies are insufficient
CARE & FOLLOW-UP
Attend regular follow-up visits for device programming and monitoring.
Report any new pain, swelling, fever, or changes in symptoms promptly.
Follow activity restrictions during the healing period after implantation.
Discuss MRI compatibility and other medical procedures with your healthcare team.
Keep the device information card available for healthcare providers when needed.
Important Note
Sacral nerve stimulation is not suitable for everyone. A specialist evaluation is needed to determine whether it is an appropriate treatment option based on the underlying condition and overall health.
