Kidney stones are formed by the deposition of calcium salts and other organic substances in the kidney. The formation of kidney stones is related to many factors, such as poor lifestyle habits (low water intake, low exercise, etc.), co-morbidities such as diabetes, hyperthyroidism, urinary tract obstruction or urinary tract infection, etc. If a kidney stone does not fall out, it will not cause blockage of the ureter and will rarely cause clinical symptoms, or symptoms such as back discomfort or abdominal distension. If a kidney stone falls into the ureter and causes ureteral obstruction, it will cause renal colic, which is very intense, accompanied by sweating and high fever, and may cause reflex nausea and vomiting. For the treatment of kidney stones, nowadays most of the treatment is taken by extracorporeal lithotripsy, which can be combined with Chinese medicine. If renal colic occurs, it should be treated symptomatically first to relieve the pain, and then extracorporeal lithotripsy is done. If necessary, treatment can be done by intervention or surgery. If the stone enters the bladder and is not expelled, it can grow gradually in the bladder and there can be a sudden interruption of urination and shaking the body to remove urine again. Bladder stones can be treated by interventional methods. For kidney stones, you should drink more water, exercise and exercise, and if you have other diseases, you should also be treated actively to prevent the formation of kidney stones.
