Systems and methods treat urologic dysfunctions by implanting a lead and electrode in a tissue region affecting urologic function, and implanting a pulse generator 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 urinary incontinence.
