Another test that can be done to find a kidney stone is intravenous pyelogram (IVP). During IVP, a dye is put into a vein in your arm. As the dye moves to the kidneys, X-rays are taken to watch the movement of the dye and see where a stone may be. To learn more, see the topic Intravenous Pyelogram (IVP).
Most kidney stones have calcium in them. A low-calcium diet does not often prevent stones from forming. To learn more about lowering your chance for a kidney stone, see the topic Kidney Stones.
Knowing the type of kidney stone helps guide the best treatment choice.
