Hello, the causes of kidney calculi are related to personal nutrition, abnormal metabolism, endocrine disorders, chronic pyelonephritis, urinary system infection, obstruction, foreign bodies, geography, climate and other factors. In kidney calculi, drugs below 0.6 are commonly used to expel stones, such as Shenshitong Granules and Paishi Granules. Extracorporeal shock wave lithotripsy is more than 0.6, and more than 2.0 can be treated surgically. I suggest that you go to the hospital for urine secretion surgery, find out the reason and treat it in time.
