Kidney Disease Center—Kidney StonesEn Español (Spanish Version)
Kidney stones are pieces of stone-like material that form on the walls of the kidney. The kidneys are two bean-shaped organs in the lower back. Their main function is to remove waste from the body and to balance the water and mineral content of the blood by removing water.
