Sacral nerve stimulation involves placement of a special electrode into the lower part of the spine. It is performed as a two-part surgery: During the first part, or test phase, the electrode is placed in the spine and powered by a temporary battery.
If the device results in significant improvements to continence, a second procedure converts the temporary battery into a more permanent one. If symptoms don’t improve, the second procedure involves a complete removal of the device.
Results are variable, so it’s important to talk to a trained specialist before deciding if this procedure is right for you.
