I had it done and the procedure is simple. You will need someone to drive you home though. My experience was that I couldn’t pee after and then would have over flow incontinence. I ended up with a Foley catheter and leg bag. I still had to wear a leg bag because I would urinate around/past the catheter at times. I couldn’t use the leg bag because they fill quickly and slide down my leg, pulling on the catheter causing a lot of pain. I ended up just draining the Catheter into my diaper. I still use a catheter on and off since they seem to tame the pain of the spasms. I can’t help but try to hold it which makes it painful.
