I had ct scan which show 6.4mm stone in my right
kidney and 7.6mm in left ureter and 5.5 in kidney and small stones. I had rirs procedure on one side and stent was placed on both side. Now I want to know if the other stone passed as I am drinking a lot of fluids. Can I get a ultrasound done ? Can it show 6.4mm stone ? As I don't want to have ct scan again
