I do not believe they blast them anymore. They can go in with a laser and blast it, or I think they go in and physically grab it. Either way, they go in through your... Ya know, and get it.
Also, someone asked about preventing them, supposedly a glass of lemon water everyday keeps the stones away. Apparently the acidity in lemon prevents them from forming. I guess lemon can also help if u have a stone, by helping to break it down
The iv pain meds they gave me at the hospitol were the bomb. Started with a D I think. It took the pain away almost instantly and actually let me sleep. They were giving me alot of percoset in pill form, which would drop the pain from a 10 to maybe a 7, which really isn't all that great. The iv meds I really had to tell them I was in Agony to get.
