Should i be worried about a shadow after a kidney ultrasound?
Patient: Hi my son had a kidney ultrasound done a week ago and they seen a shadow , we had another one done today and showed the same thing. I have an appointment on feb 5th to see the specialist and I m panicking..I hope it is just the pic messed up. SHould I be worried? Doctor: Shadown on kidney ultrasound usually means a calcification like a kidney stone.  A CAT scan will really highlight what is causing it and that would be the next step.
