Repeated stones in the right kidney may be caused by dietary factors, metabolic abnormalities, local factors in the urinary tract. 1. Dietary factors: if the patient long-term large intake of high protein, high sodium, high sugar food will cause increased urinary calcium, uric acid excretion and reduced citrate content, or drinking less water caused by the concentration of urine, so that the concentration of various stone-forming components is too high, resulting in the appearance of stones. 2. Abnormal metabolism: most of the components of the formation of stones are composed of human metabolites, the common components that can form stones in the urine include calcium, oxalic acid, uric acid and cystine, etc. Any physiological disorders that lead to abnormalities in the composition will cause the formation of stones and promote the growth of stones. 3. Local factors in the urinary tract: due to various causes of urinary tract obstruction leading to urine sludge, urinary tract infections, especially bacteria can break down urea into ammonia, so that the urine becomes alkaline, which is conducive to the deposition of phosphate and carbonate, leading to recurrent stone formation in the right kidney. It is recommended that patients go to the regular hospital in time, under the diagnosis of the doctor, according to the patient’s specific condition performance, to take targeted treatment.
