I can tell you that kidney stone pain is just about unbearable. Unfortunately, my x-rays showed I had 5 or 6 kidney stones and I would have to have surgery to remove them. It wasn't the kind where they go through the back and open the kidneys, however. It was a more modern treatment that was similar to the uteroscopy discussed in the article. I was under general anesthesia, and I had to stay in bed for at least a week, but the stones were completely gone.
