What Causes Kidney Stones? Symptoms & Signs
As the kidneys filter waste from the blood, they create urine. Sometimes, salts and other minerals in urine stick together to form small kidney stones. These range from the size of a sugar crystal to a ping pong ball, but they are rarely noticed unless they cause a blockage. They may cause intense pain if they break loose and push into the ureters, the narrow ducts leading to the bladder.
A kidney stone is a hard, crystalline mineral material formed within the kidney or urinary tract.
