after some weeks of intermittent blood in my urine, a CT scan found a stone in my left kidney. This stone is too big to pass so they'll have to remove it. This stone is located on top of ureter, so just before leaving the kidney.
1- Sometimes the blood is brown, sometime pink/red. Why is the blood colour isn't always the same ?
2- What makes stones moves ? Sometimes I see blood after doing some physical activities (which seems logic) but sometimes I have blood and didn't do any abrupt mouvement.
3- I never had any pain. How a big stone like that, that gives me blood in my urine, don't get me any pain ?
