Kidney Stones


Kidney stones form in the urinary system when the water and waste in your urine are out of balance. When this happens, certain types of waste crystals separate from the urine. The crystals build up and form kidney stones. You may have 1 or more kidney stones.

  • Stay active. Your stones may pass more easily by if you stay active. Ask about the best activities for you.

After you pass your kidney stones:

Once you have passed your kidney stones, you may need to do a 24-hour urine test. You will need to save all of your urine for 24 hours. Each time you go to the bathroom, you will urinate into a container. Then you will pour your urine into a larger container that is kept cold. You may be told to write down the time and amount of urine you passed. At the end of 24 hours, the urine is sent to a lab for tests. Results from the test will help your healthcare provider plan ways to prevent more stones from forming.

Help prevent kidney stones:

  • Drink at least 8 to 12 (eight-ounce) cups of liquid every day. Half of the liquid you drink should be water. Increase the amount of liquid you drink when you exercise or do activities that cause you to sweat. Also increase the amount you drink when the weather is hot.

  • Ask if you need to make changes in the foods you eat. You may need to limit certain foods. You may need to limit nuts, chocolate, coffee, and certain green leafy vegetables. You may also need to limit meat and salt.

Contact your healthcare provider if:

  • You have a fever.

  • You have trouble passing urine.

  • You see blood in your urine.

  • You have severe pain.

  • You have any questions or concerns about your condition or care.
