Sacral nerve stimulation, also termed sacral neuromodulation, is a type of medical electrical stimulation therapy. It typically involves the implantation of a programmable stimulator subcutaneously , which delivers low amplitude electrical stimulation via a lead to the sacral nerve , usually accessed via the S3 foramen .
A sacral nerve stimulator is a small device usually implanted in the buttocks of people who have problems with bladder and/or bowel control. [1] [2] This device is implanted in the buttock and connected to the sacral nerve S3 by a wire. [3] The device uses sacral nerve stimulation to stop urges to defecate and urinate by sending signals to the ...
Sacral nerve stimulation was originally used in urinary incontinence. It was first used to treat FI in 1995. The procedure involves implantation of an electrical device (an implanted pulse generator, IPG) which applies a low amplitude electric current to a sacral nerve (usually S3). This appears to modulate the nerves and muscles of the pelvic ...
Electrical stimulation using implantable devices came into modern usage in the 1980s and its techniques and applications have continued to develop and expand. [16] Recent reviews highlight how neuromodulation is increasingly utilized across multiple medical subspecialties, providing clinicians with novel therapeutic options for both painful and non-painful complex disorders.

From 1969 onwards Giles Brindley [1] developed the sacral anterior root stimulator, with successful human trials from the early 1980s onwards. Although both sphincter and detrusor muscles are stimulated at the same time, the slower contraction kinetics of the bladder wall (smooth muscle tissue) compared to the sphincter (striated muscle tissue) mean that voiding occurs between the stimulation ...
The most common use of SCS is failed back surgery syndrome (FBSS) in the United States and peripheral ischemic pain in Europe. [4] [5]As of 2014 the FDA had approved SCS as a treatment for FBSS, chronic pain, complex regional pain syndrome, intractable angina, as well as visceral abdominal and perineal pain [1] and pain in the extremities from nerve damage.
Pain can increase during menstruation in women. [8] [9] [2] People with severe and disabling sacroiliac joint dysfunction can develop insomnia and depression. [10] Sacral rotation can be transmitted distally down the kinematic chain and, if left untreated over a long period of time, may lead to severe Achilles tendinitis. [11]
[11] [12] The cysts are often multiple, extending around the circumference of the nerve, and can enlarge over time to compress neighboring nerve roots, to cause bone erosion. [13] The cysts may be found anterior to the sacral area and have been known to extend into the abdominal cavity. These cysts, though rare, can be found to grow large ...
