How is sacral nerve stimulation / neuromodulation surgery carried out?
During sacral nerve stimulation surgery, a thin electrode is placed on sacral nerves (peripheral nerves, not spinal cord) within the area of the sacral bone/sacrum. A neuromodulation system emits weak electrical impulses via the electrode to help control the function of the rectum and the bladder.
Sacral neuromodulation surgery only lasts about 45-60 minutes and requires anesthesia and a short hospitalization. The hospitalization is necessary to adjust the pelvic floor pacemaker that is carried on the skin during a test phase of 2-4 weeks. Testing this treatment option is a special advantage because you can evaluate its effectiveness.
The definite implantation of the system (normally into the fat tissue of the upper buttocks) is performed after the test phase. Your physician can adjust its parameters at any time externally with a control unit. The average battery lasts about 7 years, but this depends on the parameters of sacral nerve stimulation. If the battery is discharged, it can be replaced during a small operation.
