Sacral nerve stimulation is sometimes referred to as the ‘pacemaker for the bladder’. As University College Hospital London Consultant Urologist, Mr Jeremy Ockrim explains in his article for totalhealth:
In an ‘overactive bladder’ the sacral nerves send unwanted messages to the bladder, 
causing it to contract suddenly, which is what causes the urgency, and empty without due warning... Sacral nerve stimulation works by interrupting this ‘faulty circuit’ and restoring normal communication between the nerves, brain, and bladder.
He goes on to explain that the same nerves send pain messages to the brain and, by using sacral neuromodulation, 40–70% of people suffering from pelvic and bladder pain will have reduced pain.
Sacral nerve stimulation is an exciting new development to help patients suffering from this embarrassing problem and patients will find this plain English article is highly informative.
