A method and system for neuromodulation therapy for urinary incontinence and urological disorders comprises an implantable lead stimulus-receiver, and an external stimulator-transmitter having a power source, controlling circuitry, and predetermined programs. The stimulator-transmitter further includes a primary coil which inductively transfers electrical signals to the lead-receiver, which is also in electric contact with the sacral nerves. The external stimulator-transmitter emits electrical pulses to stimulate the sacral plexus according to a predetermined program. In one mode of operation, the operator may program one of the predetermined programs, in another mode, the electrical parameters may be "custom" programmed for the patient, and stored in the memory.
