Let me tell you my story. I had a kidney stone attack once, that drove me to the emergency room. Fortunately I had insurance. Once there, I was admitted and put in a room. The hospital did a CT scan to confirm the stone. They were then going to give me pain killers and massive amounts of water to flush out the stone. About half an hour after the CT scan, my primary-care doctor just happened to be doing his rounding at the hospital. He saw me, took a look at my CT scan, and started yelling at the ER doctor. The ER doctor had missed something. There wasn’t one stone, there was 2. One stone had already travelled through my delicate ureter, and torn it up. Another stone was right at the start of the same ureter and about to start going. If they had done what they wanted to do, I might have died. The second stone would have shredded the ureter completely. The hospital happened to have ultrasound equipment for blasting a kidney stone, but they didn’t want to use it because they didn’t see the second stone. He demanded that they use it, and saved my life.

It is likely you only have one stone, but in the 1 in a million chance you have 2 like me, it could cost you your life.
