Kidney stone patients need to drink water at night, patients with stone disease need to drink more water and urinate more. In principle, drinking water should keep the total amount of night bacteria, etc. should be >2500ml to prevent excessive concentration of urine and lead to further increase of stone volume, and at the same time, as far as possible, according to the location and size of stones, etc., choose extracorporeal shock wave lithotripsy or choose medication for stone removal, so that the stones can be discharged from the body as soon as possible to restore a healthy state, especially after extracorporeal shock wave lithotripsy or medication for stone removal, more water needs to be drunk. In principle, a certain amount of water should be added at night before going to bed or after going to sleep as much as possible, because urine concentration occurs most often at night during sleep, when patients do not drink enough water. At this time, the solute concentration component in the urine is relatively high, and it is possible that in a prolonged environment, the volume of the original stone will further increase. Therefore, drinking more water and urinating more often is a key step in preventing stone disease, and as much as possible, the amount of water should be replenished equally throughout the day and night.
