It is not normal to form a kidney stone. Formation of a stone implies there is something abnormal in the urinary system. There are always many chemicals in everybody’s urine and in most people these chemicals are dissolved in the urine. In other words, the chemicals are not solid.
When there is a chemical or physical abnormality in the kidneys, the chemicals may precipitate (become solid particles). These particles can become tiny crystals which eventually grow to become a kidney stone.
