Sacral nerve stimulation permits electrical stimulation of the sacral nerves via an implantable neurostimulator device.
It is meant to treat following conditions:
- Refractory urgency, urge incontinence
- Voiding difficulty
- Pelvic pain
- Faecal incontinence
- Anal pain
- faecal incontinence
- Interstitial cystitis
- Spinal injury
- Neurodegenerative disease
- Sexual dysfunction
Stimulation of the sacral nerve causes contraction of external sphincter and pelvic floor muscle which causes the inhibition of bladder contractions which may be involuntarily releasing urine. Researchers currently believe that the sacral neuromodulation blocks the c-afferent fibers, which are an important part of the afferent limb of a reflex pathway believed to be responsible for incontinence.
Sacral nerve stimulation is a promising and durable treatment for refractory conditions. All patients have reported major benefit for above mentioned conditions.
