If the examination reveals that there are stones in the urinary system, one should maintain sufficient water intake, which should be between 2,000-2,500 ml in 24 hours, and preferably not greater than 3,000 ml, because water intake greater than 3,000 ml will significantly increase the load on the human heart, as well as the burden on the kidneys in filtering the urine. However, if the amount of water consumed is less than 2000ml, it will lead to a decrease in the amount of urine filtered by the body due to unnoticeable water loss, for example, through the mucous membranes of the skin of the oral cavity, and therefore will not be conducive to the elimination of stones, and will even aggravate the risk of stone formation. Therefore, for patients with stones, it is recommended to maintain an adequate water intake of about 2500 ml for 24 hours. When stones are found, patients should maintain vertical movement, such as playing basketball, running and jumping, or oral dilatation of the ureter drugs, can assist in stone discharge. For stones less than 6mm in diameter, conservative lithotripsy is usually possible.
