What happens during a kidney stone analysis?
You will get a kidney stone strainer from your health care provider or from a drug store. A kidney stone strainer is a device made of fine mesh or gauze. It is used to filter your urine. You will also get or be asked to provide a clean container to hold your stone. To collect your stone for testing, do the following:
Filter all your urine through the strainer.
After each time you urinate, check the strainer carefully for particles. Remember that a kidney stone can be very small. It may look like a grain of sand or a tiny piece of gravel.
If you find a stone, put it in the clean container, and let it dry.
DO NOT add any fluid, including urine, to the container.
DO NOT add tape or tissue to the stone.
Return the container to your health care provider or laboratory as instructed.
If your kidney stone is too large to pass, you may need a minor surgical procedure to remove the stone for testing.
