What are kidney stones?
Kidney stones are small “pebbles” of salt and minerals in the urine. They can be as small as a grain of sand or as large as a golf ball. They form when there is a change in the balance of salt and minerals in the urine. They are more common in men and affect almost 10% of Americans. Common types of stones are calcium oxalate and uric acid stones.
