Any kidney stone that is above 6 mm in diameter is considered a large kidney stone, as stated by NHS. Such stones will not get better on their own so medical treatment may be required to heal. Small kidney stones, 4 mm and below in diameter, will heal on their own after a while and may not make a person experience pain.
