How long does it take for a kidney stone to be discharged in general is related to the size and location of the stone, and cannot be generalized. Kidney stones are common diseases of the urinary system. If the stones are less than 6mm in the upper and middle calyces of the kidney or in the renal pelvis, and there is no ureteral stenosis, the stones can be discharged smoothly in 1-2 weeks by drinking more water, urinating more often, exercising more, especially jumping exercises, and auxiliary drugs, such as urinary stone pass, money grass granules, stone removal granules, etc. If the stone is larger than 6 mm or there is ureteral stenosis, it is usually difficult to expel the stone by itself. Some patients with stones larger than 2 cm also need to undergo surgical stone extraction to remove the stones. Patients with kidney stones are advised to avoid blindly discharging stones, and should promptly visit the urology department of the hospital to choose the next treatment under the guidance of a professional physician.
