"The doctor found 2 small kidney stones in my uterine tract, and blood in my urine along with infection. My kidneys were clean and normal."
If you have problems with your "uterine" tract, then you have bigger problems than stones. You might want to see an ob/gyn.
Sounds like yours isn't that bad. Sometimes they have to blast them into smaller pieces. My brother had a camera shoved up his pecker and he said that wasn't fun. I know I'm probably not putting you at ease, sorry!
