Kidney stone disease. (Redirected from Kidney stone) Kidney stone disease, also known as urolithiasis, is when a solid piece of material (kidney stone) occurs in the urinary tract. Kidney stones typically form in the kidney and leave the body in the urine stream. A small stone may pass without causing symptoms.
Kidney stones (calculi), stone-like crystals of differing sizes and shapes, can develop in one or both of the kidneys. Medically known as nephrolithiasis, kidney stones can block the flow of urine and in extreme cases result in a kidney failure. These occur when salts present in the urine form a solid lump or stone. Most kidney stones do not require surgery and are passed out of the body painlessly when you urinate.
