Hi MK,
I've had over 40+ lithotripsies, along with aton more surgeries. Anyway, the 2500 they are referring to is how many "shocks" you received to the stone. Average is anyway between 2000-4000. 4000 is the max at one time for each stone. I've had 4000 delievered to 6 different stones at one time. Totally idiots!!! This was back in the "old days" when ESWL first came out in 1987, I was 16. Plus, back then the machine (there was only one) was
EXTREMELY POWERFUL!
My back was black and blue and it looked like I had been hit with a baseball bat. Back to what I was saying about the max shocks. The docs did sooooo much damage to my kidneys, I eventually had to have my left one removed almost 2 yrs. ago and my remaining one is dysfunctional/failing.
I won't go on dialysis, so that will be it for me. Also, all the stones and surgeries have landed me in pain management. I take the most potent pain meds on the market today (what you would normally see cancer patients on). Please be careful with the ESWL's, ok??? Take care!!

(By the way, my screen name used to be ksqueen, if this story sounds familiar. My name was changed.)
P.S. Today's machines are far less powerful. This is why you end up having repeat procedures done. Do you see the cycle??? I'm sure I put many docs kids through college, bought the docs mansions and cars...you name it. I was their cash cow (having over 400+ stones), along with other patients. Don't fall into that trap. If your doc just keeps wanted to do ESWL and you don't think it's necessary, don't do it!! By all means, if you are miserable, then yes, do something. Just try not to have too many ESWL's done. It's not worth it.
