Guess what!!!
I went to the doctor for the cat scan and my other kidney stone is gone!! Can you believe it. Here I was all set to go into the hospital today to have it blasted and it's gone. I passed it (which I can almost never do) without even knowing it!!! (And it had been a pretty nice size one!)
Right now I do have an itty-bitty stone on the right side but he said for the size that it is it shouldn't give me any problems and I could probably pass it without even knowing it because it's so small.
This is the closest to stone-free that I've been in over four years!!
