This could have prevented your need for surgery and made everything else you tried work better. I have done six of them. The first one was the most intense because I had 45 years of stones stopping up my ball bladder causing horrible pain if I ate beans or broccoli. Now I can eat both without even getting gas. The biggest stones that came out of me were about and inch and a half in diameter. The smallest look like green rice. I got about a pint of them the first time. Since then no more than a half a cup per flush. And no more big ones.
