Stones are usually formed due to the concentration of urine, crystal formation, or bile stagnation and other factors, commonly found in kidney stones, gallstones and so on. 1. Kidney stones: Usually high urinary calcium, high urate, and low water intake will reduce the urine volume, which may lead to the phenomenon of concentration of urine, resulting in the gradual formation of crystals, which will gather in the ureter where there is a physiological narrowing to form stones. Finally, there will be frequent urination, urinary urgency, urinary pain and other uncomfortable symptoms. 2. Gallstones: usually due to diabetes, obesity, rapid weight loss and other factors, resulting in bile stasis; secondly, biliary tract infections and autoimmune diseases and other factors, will continue to produce gallstones, thus aggravating their formation; some patients will have pain in the upper right abdomen, jaundice and other symptoms. When the symptoms of stones appear, it is recommended to consult the urology department or general surgery department for treatment.
