This device is implanted over the sacral<unk> <unk>  of the spinal cord; controlled by an external transmitter, it delivers intermittent stimulation which improves the ability to empty the bladder. It may also assist in defecation and also may enable male patients to have a sustained full erection. The device is implanted in one of two regions, either through intrathecal administration or extradurally. It is often performed in conjunction with a dorsal rhizotomy, and many groups believe that the best results are only seen when this procedure is performed alongside the implantation. The rhizotomy will remove sensory reflexes, which in men may include sexual reflexes. For some patients this is a major drawback to the device. For others, the benefits outweigh the downside. The related procedure of sacral nerve stimulation is to control incontinence in otherwise able-bodied patients.
