The sacral nerves control signals between the brain and bladder, bowel and pelvic muscles. Conditions like overactive bladder, fecal incontinence or chronic pelvic pain happen due to miscommunication between these areas. SNS aims to reset this nerve signaling and restore normal bladder and bowel function.

The implanted device is programmed externally by a clinician. Low-voltage pulses are delivered to sacral nerves through thin wires attached to the device. These pulses block abnormal signals and stimulate the nerves to regain control. Adjusting the pulse frequency, width and amplitude helps achieve optimal results.

Candidate Selection and Testing

Not everyone is a suitable candidate for SNS. Patients must meet specific criteria and undergo successful testing before permanent implantation. Doctors screen for factors like severity of symptoms, failure of prior treatments and ability to understand how SNS works.

During testing, temporary wires are placed near sacral nerves through the skin to provide stimulation for 3-7 days. If there is significant improvement in symptoms, the patient may be selected for permanent implantation. Global Sacral Nerve Stimulation Testing helps predict long-term success without risks of open surgery.

Permanent Implantation Procedure of Sacral Nerve Stimulation

If testing shows positive response, the patient undergoes permanent implantation. It is done as an outpatient procedure under local anaesthesia or sedation. An incision is made near the buttocks to create a pocket under the skin.

The permanent SNS device is then placed and secured inside. Thin leads or wires are passed through separate incisions to the sacral nerves. The device is then programmed to deliver the optimum stimulation for that patient. Incisions are closed with dissolvable sutures.

Programming and Follow Up Care

Specialists use an external programming device to personalize stimulation settings for each patient. Settings are adjusted during follow-up visits based on symptom response. Regular programming helps maintain effectiveness over several years.

Patients are advised about managing the device and recognizing potential issues. Follow up exams monitor progress and stimulation levels are adjusted as needed. Early trials have shown SNS significantly improves quality of life for thousands of people worldwide.
