Sacral nerve stimulators can help to control bladder function. The sacral nerves control the bladder and the muscles related to urinary function. InterStim Therapy uses a small device, resembling a pacemaker, to deliver mild, painless electrical pulses to the sacral nerves in order to regulate bladder function. InterStim Therapy is a reversible treatment which may be discontinued at any time by turning off or removing the device. InterStim Neuromodulation is used by members of the Urology Division as well as the Women’s Center for Continence and Sexual Health at Premier Medical Group.
