I'm passing a stone now. This is my third this year and the last one was only two and a half months ago. My Urologist wants me to have the procedure where she zaps the "six" I have left and they break up into smaller prices BUT, after reading about the procedure (done under general anesthesia), I'm not sure if I'll have it. After researching it on the internet and talking to someone who has had it done, I have found it is extremely painful and may have to be repeated. I have heard of a couple of companies that sell a product that "supposedly" causes the stones to grind down to a powder that would pass through the uretors painlessly. Has anyone heard of such a product or, even better, tried it? I really don't want to have the microwave procedure. Thanks for reading.
