stimulation test. It benefits from a 2-stage procedure, which enables the patient to assess acceptability, and the clinician to evaluate efficacy prior to permanent implantation. Objective: The aim of this study was to evaluate in a prospective, randomized setting if the 2-stage implant, compared to a 1-stage implant, leads to a superior subjective or objective outcome of sacral nerve stimulation after implantation of the pulse generator in patients with lower urinary tract symptoms. evaluation interval and (2) a second stage with. Post-operatively patients go home the same day. The recharge-free InterStim neurostimulator streamlines the implant procedure with a design that eliminates the need for the lead extension and uses fewer set screws. Peripheral nerve evaluation (PNE) was not performed. In the first stage, a quadripolar-tined lead is implanted (stage 1). The first stage is a trial phase to see if SNS will improve your symptoms.
