There are three main types of stones in the body: urinary stones, biliary stones and gastrointestinal stones. Generally speaking, food has little effect on stone removal, and it is recommended to use different treatments according to the different conditions of the stones. The first type of stone is the biliary system stone, there are gallbladder stone, common bile duct stone and intrahepatic bile duct stone. The natural expulsion rate of gallbladder stones is around 5%, indicating that the stones can sometimes be expelled on their own. A regular, light diet is sufficient, and early surgical treatment is recommended for those with recurring symptoms. The second type is urinary stones, including kidney stones, ureteral stones and bladder stones. Smaller stones can be treated by drinking water to increase urine output, supplemented with stone-promoting medications such as lithotripsy granules, moneywort granules, nephrolithotripsy, urolithotripsy, antispasmodic medications such as 654-2, etc., and bouncing to make the stones pass through the urethra and be expelled from the body. However, for larger stones, which cannot be discharged by the above methods, extracorporeal shock wave lithotripsy is needed to break up the stones in the urinary system and then discharged by the above methods. For stones that cannot be broken, they can be removed by percutaneous nephrolithotomy, ureteroscopy or cystoscopy, or by microscopic holmium laser lithotripsy, in which the stone is broken and flushed out with water or removed with a stone net. The third type of stone is a gastrointestinal stone, which is called a gastrolith in the stomach and an enterolith in the intestines. If the stomach stone is small, it can be treated with sodium bicarbonate along with medications such as proton pump inhibitors. If they are large and cannot be drained, a gastroscope is needed to break up the stomach stone before draining it. When they cannot be broken up and drained, the stomach needs to be surgically cut open and removed. If formed in the intestines, small enteroliths can be lubricated by taking laxatives such as liquid paraffin and vegetable oils to promote stone expulsion. Again, failure to expel requires open surgery to surgically squeeze the enteroliths, and if they can be squeezed into the cecum, they can usually be expelled on their own. If the intestinal stone is hard and cannot be squeezed, surgical incision of the intestinal canal is required to remove the stone.
