The formation of kidney stones is related to a variety of factors such as metabolic abnormalities, local factors in the urinary tract, drugs, diet and so on. 1. Abnormal metabolism: Studies have shown that most of the stones are made up of human metabolites, so when physiological disorders lead to abnormal metabolism of calcium, oxalic acid, cystine and uric acid in the urine, it is easy to promote the growth of stones. 2. Local factors in the urinary tract: Considered to be related to urinary tract infection, urinary tract obstruction and the presence of abnormalities in the urinary tract and other local factors leading to urinary stasis. 3. Drugs: common drugs are indinavir, silicate, aminopterin, acetazolamide, vitamin D, vitamin C, glucocorticosteroids and so on. 4. Diet: Long-term intake of foods high in sugar, protein and salt will increase the risk of kidney stones, followed by high intake of oxalic acid-rich foods and low water intake. All in all, the prognosis of kidney stones is good after standardized treatment, patients need to cooperate with doctors to actively treat, strengthen daily life management, and follow up on time.
