Hi, I have gone through your query. You are asking about Bladder pacemaker. This implantable pacemaker stimulate nerves, which regulates muscle of bladder. In this way patient can control urine storage and release. It a small box that is implanted surgically in lower abdomen. A wire comes out through this containing 4 platinum electrodes which are put inside sacral canal. And attached to sacral nerves which regulates bladder function. Once installed, it is programmed outside by your doctor to signal bladder. You can regulate it by yourself within certain limits set by doctor. For scoliosis there are several treatment options like physical therapy, occupational therapy, bracing , casting, surgery. You can discuss about this with your treating doctor. Do consider a positive feedback as a credit to my work. Let me know if you have any further questions.
