Stage 1 is designed to ensure that a sacral neurostimulator will help your urinary symptoms. Essentially, this lets you try it first with an evaluation. Typically, the first step is done without the need for any sedation or anesthesia. You will lie facedown so your urologist can identify the area on the back where the small wires will be placed. Using local anesthesia, tiny wires are placed in the upper buttock alongside the nerve that controls the bladder. An electrical pulse is then passed through the wire. Following placement, you will be instructed how to take care of the temporary device and asked to keep a diary of urination symptoms over the next 5 to 7 days.
