They will perform some tests to determine what type of stones you may have, how many and
how large your
kidney stones are. A KUB (
kidney, ureter, bladder) x-ray is usually given to see the stone's location and estimate their size. Also you mentioned you had an MRI recently. If it was an MRI of the abdomen, the stones would have been seen in the MRI. If they are small and can pass then a pain killer to help you pass the stones is appropriate.
