Kidney stones are mainly caused by metabolic abnormalities, urinary tract disease and stimulation with certain drugs. 1. Abnormal metabolism: any physiological disorders caused by the composition of the abnormalities may promote the formation of stones and stone growth, kidney stones are mainly due to the formation of calcium, oxalic acid, uric acid and cystine and other components commonly found in the urine stones. 2. Urinary tract disease: If the patient himself suffers from urinary tract obstruction, urinary tract infection or the presence of foreign bodies in the urinary tract, it will induce the formation of stones. 3. Drug stimulation: if the patient has taken the drugs that make the concentration of urine in the body high but the solubility is relatively low, such as the compound Liping amphotericin tablets, methylprednisolone tablets or vitamin C tablets, it is easier to promote the formation of kidney stones. Kidney stones can be triggered by many factors, such as climate, diet, medication, etc. Patients should minimize or avoid the triggering factors according to the professional doctor’s guidance after the diagnosis is confirmed, so as to prevent recurrence of the condition and aggravation of the symptoms.
