Even though I failed the urodynamics test, which is either you pass or fail, no range chart. I did my own research and found out that you can do the mid urethral sling later if you have incontinence after your copocleisis surgery. It's called the staged approach, you can look it up. My doctors did not tell me about it, I simply told them I wanted to do the staged approach after reading reputable medical websites. If sling is done later as a separate procedure it only takes about 10mins. I am SO glad I did not do it at the same time because I have not had any incontinence since my hysterectomy and colpocleisis surgery, and my surgeon said my prolapse was one of the worst she had seen. I am now almost 1 year post-op and can pee very normal without the mid urethral sling. Each decision is personal to each of us as patients, and there are no guarantees, so good luck on whatever you decide. I wish you well on your surgery.
