Abstract
Systems and methods treat urologic dysfunctions by implanting a lead and electrode in a tissue region affecting urologic function, and coupling the lead to an external pulse generator. If desired results are achieved, the external pulse generator is removed and an implantable pulse generator is implanted in an anterior pelvic region remote from the electrode. Bilateral stimulation of the left and/or right branches of the dorsal genital nerves using a single lead implanted in adipose or other tissue in the region at or near the pubic symphysis is able to treat urologic dysfunctions.
