A Brief Overview of Sacral Nerve Stimulation

Published Date : July 19, 2017

Sacral Nerve Stimulation also known as sacral neuromodulation is a medical therapy which uses electoral stimulation. This therapy customarily involves regulation of a stimulator which is programmable in the subcutaneous tissue that gives out less amount of electric stimulation to the sacral nerve through a lead, normally annexed through the S3 foramen.

The interStim is endorsed by the Food and Drug Administration of the United States as a stimulator of the sacral nerve as it proves to be a treatment for various conditions like urinary retention (unable to entirely vacant the bladder), involuntary urination (leakage of urine) and frequent urination. Nationwide Children’s hospitals has conducted an experiment on constipation in children as it is said that constipations caused due to damaged nerves in surgical procedures may also be cured by the Sacral Nerve Stimulation.

The central nervous systems send signals to the nerves and the brain when they stop communicating efficiently as it causes disorder of the bladder and the bowel. The dominant nerve is routed from the brain, through the back along the spinal cord which is generally known as the sacral area and regulates the functions of the pelvic floor, bladder and urethral sphincter in day-to-day life. The sacral nerve that is located in the lower back is stimulated which then sends a signal that maneuvers a deflation inside the pelvic floor. As time passes these deflations build up durability of the muscles and organ inside it. This efficiently eliminates all symptoms of bladder and bowel disorders.

In order to treat patients suffering from urinary issues numerous studies have been introduced into Sacral Nerve Stimulation. When this procedure is applied, appropriate screening of the patient is necessary, as certain disorders like carcinoma in-situ that target the urinary tract have to be dealt with in a different manner. An external pulse generator which is temporarily connected for a period of 1-2 weeks at the wire leads of S3 foramen is received by the applicant and a permanent stimulator with the wire leads are given to the applicant which is fixed in the subcutaneous tissue in case of the symptoms being reduced by 50 percent.  To check if the permanent device is rendering improvement and generating pulse adequately to the symptoms a follow up in conducted 1-2 weeks later. Few complexities caused by this therapy are pain, infection, nonessential stimulation and bleeding. Presently, this stimulation therapy requires battery restoration 5-10 years post application also depending on the aptitude of the therapy. The Sacral Nerve Stimulation therapy has proven to be extremely successful and has been a useful option for people with urinary tract disorders.
