If i take my x ray without dye will they be able to see any kidney issues or stones? or is the dye needed ?

IVP w/ contrast: Depending on what u r looking for, the "dye" (called iodinated contrast) can significantly improve the chances of finding it. While about 15% of kidney stones can b seen w/o contrast, that leaves about 7 out of 8 stones that can't be seen. The "dye" outlines the collecting ducts of the kidney (and the kidney itself); also, "X-ray tomograms" (not CT, but with plain films) can reduce need 4 contrast
