Question: What causes kidney stones in children?
Answer: Most kidney stones are caused by high levels of calcium, oxalate, or phosphorus in the urine. These minerals are normally found in urine and do not cause problems at normal levels.

Certain foods and beverages may increase the chances of having a kidney stone in children who are more likely to develop them.

When children can’t move for a long time, for example when a child is in a cast after surgery, the chances of developing a kidney stone are higher. When children aren’t moving, their bones may release extra calcium into the blood.
