Patients with kidney stones can drink corn juice, which will not lead to an increase in the size of the stones and will not lead to further aggravation of the painful symptoms of the stones, and will not have any effect on the patient after proper ingestion. Patients with kidney stones have to avoid drinking strong tea for a long time and consuming foods rich in oxalic acid or purines, such as chocolate, cocoa, prunes, strawberries, celery, spinach, lettuce, beets and other foods. At the same time, we need to reduce all kinds of seafood products, animal offal, and long-term heavy drinking, and also need to pay attention to drink more water to prevent urine concentration, which is the main measure to prevent the formation of kidney stones. Small amounts of corn juice or sugar-free beverages will not increase the size of stones or worsen the symptoms of stones. The formation of kidney stones is a slow process, which is related to many factors, including dietary factors, urinary tract obstruction, infectious factors, the body’s own factors and the presence of metabolic diseases.
