Strongly echogenic light spots in both kidneys usually indicate the presence of kidney stones. Diet should include drinking more water, eating more fruits and vegetables, and reducing the intake of foods that can cause stone formation. Patients with kidney stones should consume more than 2,000ml of water per day to prevent further stone enlargement, and smaller stones can be excreted in the urine. More fresh fruits and vegetables should be consumed to prevent further enlargement or recurrence of stones. Roughage and fiber can be added to the diet appropriately, which can reduce the urinary calcium discharge and prevent further enlargement of urinary stones. However, some foods should be avoided, such as peanuts, spinach, almonds and other foods with high oxalic acid content, as well as broth, animal offal, seafood and other high-purine foods, which can cause existing stones to increase in size or form new stones. When both kidneys have strong echogenic light spots, you should seek medical attention in a timely manner, under the guidance of a professional doctor to standardize the treatment and prevention of complications, diet can only be used as an auxiliary means.
