General precautions in daily life: 1. Drink more water and hold less urine to prevent urine concentration. Drink at least 250 ML of water daily to reduce the precipitation of solid components in urine and prevent the formation of new stones. 2, increase the amount of activity, such as running, jumping, jumping rope, up and down the stairs, etc., can promote the stone mobile discharge. 3, long-term bedridden patients, should help the patient to move more, turn over regularly, in order to reduce the bone off for bone calcium, enhance the smooth flow of urine. 4, limit the intake of calcium-containing, oxalic acid-containing food and animal protein. Such as milk, cheese, all kinds of beans; spinach, beets, cocoa, coffee, chocolate, black tea, strawberries; animal offal heart and liver, brain, etc. 5, strengthen physical exercise, increase the body’s immune function, improve the working environment, avoid long-term high-temperature work, targeted improvement of water quality, reduce the concentration of excessive mineral content in drinking water, is the fundamental way to prevent the formation of stones. For patients with stone composition analysis results: Oxalate stones: mostly generated from food, some can also be generated by endogenous mechanisms. Diet should abstain from vegetables high in oxalic acid, such as spinach, amaranth, water spinach, green garlic, onion, wild rice, and various kinds of bamboo shoots. Oral administration of 5 mg of folic acid and 10 mg of pyridoxine can prevent the conversion of glycine to oxalic acid. Patients with these stones should drink more water. Phosphate stones: Since they are formed in alkaline urine, more acidic foods should be consumed, while limiting foods high in calcium. Acid-forming foods such as livestock and poultry meat, fish and shrimp, eggs, cereals and peanuts, etc. Uric acid stones: are caused by hyperuricemia, so foods containing high purine should be prohibited, such as animal offal, thick broth, mushrooms, peas, lobster, sardines, anchovies, roe, etc. You should eat more vegetables and fruits and drink more water to reduce the concentration of uric acid. Calcium salt stones: It is advisable to limit milk, cheese, shrimp, etc., which are high in calcium. More acid-forming foods, such as meat, poultry and eggs, should be eaten to make the urine acidic and drink plenty of water. Cystine stones: It is advisable to limit methionine and acidic food (animal food) and eat more alkaline food (plant food) to make the urine alkaline and drink a lot of water.
