A. Urinary stones As you know, many diseases tend to cause urinary stones. They are mainly related to the following diseases. Hyperparathyroidism can increase calcium ions in blood and urine; gout patients have increased uric acid in blood and urine, which can easily form uric acid stones; patients with fractures, bone tuberculosis, etc. are bedridden or fixed in casts for a long time, or patients with spinal cord injury or limb paralysis, which can easily cause bone decalcification and their urinary calcium increases; in addition, patients with spinal cord injury may also cause bladder paralysis and urinary retention, which makes the crystals in urine easy to precipitate; urinary tract foreign bodies such as electric wire, straw, glass filaments, grass stems, etc. are inserted into the urethra and then slide into the bladder, forming bladder stones. In addition, diseases such as pyelonephritis, cystitis, and urinary tract infections tend to form stones. Hepatobiliary stones are mainly caused by the following diseases. Patients with hemolytic anemia are prone to bile pigment stones, because hemolysis releases a large amount of hemoglobin, which increases bilirubin in the blood after decomposition; cholecystitis, chronic hepatitis, biliary roundworms and intestinal parasites are prone to cause this disease; diabetes, cirrhosis, hyperthyroidism patients have reduced bile salt synthesis and excretion in the bile; patients who have had small intestine removal or small intestine fistula and vagotomy for duodenal ulcer have disorders of bile salt metabolism and the gallbladder is not easily emptied of bile. Patients who have undergone resection of small intestine or small intestine fistula and vagotomy for duodenal ulcer are prone to hepatobiliary stones due to the disturbance of bile salt metabolism and the difficulty of bile evacuation from the gallbladder. It can be seen that diseases are often causal, both as pathological products and pathogenic factors. In the process of treating diseases, comprehensive analysis and judgment should be made and a realistic treatment plan and program should be formulated. In order to achieve the purpose of eliminating the cause and treating the disease.
