In modern society, with the continuous improvement of people’s living standards, the incidence of urinary stones is also increasing, many patients after surgical or non-surgical treatment, the stones are temporarily removed, but will soon generate new stones, making patients very painful, so we have to pay attention to the following aspects of life, to change dietary habits, to prevent the recurrence of stones. 1, the formation of stone crystals in the urine is the main factor causing stones, so usually pay attention to drinking a lot of water, and at night, we should also drink water to ensure that the daily urine volume is greater than 2000 ml, which can not only prevent the formation of stones, but also can help the discharge of smaller stones. 2, regulate the dietary structure, decide to prevent stones diet. 1, increase the intake of dietary fiber. Cereals, potatoes and fresh vegetables are rich in fiber, eat more fresh vegetables can increase dietary fiber, thus reducing calcium oxalate and uric acid production in the urine. 2, increase the intake of calcium-containing foods. Low calcium can make the body osteolysis is greater than bone generation, blood and urine calcium content are increased, promote the generation of stones. Therefore, the diet should increase the intake of calcium-containing foods, such as milk, fish, shrimp, kelp and so on. Note that do not take calcium to prevent urinary calculi, too much calcium instead of increasing the risk of urinary calculi. 3, eat more vitamin-rich foods. Vitamin B6 can reduce the formation of calcium oxalate crystals in the urine, vitamin K can reduce the content of oxalic acid in the urine, green vegetables such as alfalfa, spinach, cabbage and oranges are rich in these two vitamins, often eat to help reduce the incidence of urinary stones. 3, a more comprehensive specialist examination to exclude other diseases caused by urinary stones, such as hyperparathyroidism caused by calcium and phosphorus metabolism disorders in the body and induced calcium phosphate stones, as well as tumors, prostate hyperplasia, urethral stenosis and other urethral obstruction caused by urinary tract obstruction factors, can also be formed in the urinary tract stones. 4, prevention and treatment of urinary tract infection. Urinary tract infection is the main local factor of stone formation, and is directly related to the prevention and treatment effect of urinary stones. 5, according to the urinary stone ingredients to prevent stone recurrence. Uric acid, cystine stones become acidic, while oxalate, phosphate, magnesium ammonium phosphate stones are alkaline. Fruits and vegetables can make the urine alkaline, better for the prevention and treatment of uric acid and cystine stones; meat food to make the urine acidic, better for the prevention and treatment of alkaline stones. Through the above measures we can prevent the recurrence of stones more comprehensively, I will introduce several small strategies to prevent the recurrence of stones. 1, drink less beer: beer wort contains calcium, oxalic acid, guanosine nucleotides and purine nucleotides and other acidic substances, they are used with each other, can make the body of uric acid increase, become an important cause of kidney stones. 2, eat less sugar: high sugar food can increase the concentration of calcium ions in the urine and the acidity of urine, so that calcium urate, calcium oxalate is easier to precipitate, prompting the formation of stones. 3, avoid eating high salt food: high salt food can promote the increase of urinary calcium, increase the incidence of urinary calculi, so in the daily meal cooking should be less salt, eat less salted vegetables, bacon and fried foods. 4, reduce the intake of animal protein: excessive intake of animal protein can increase the excretion of oxalic acid and calcium, thereby increasing the chances of stone formation, so in the diet should pay attention to control the excessive intake of animal protein. 5, do not drink milk before going to bed: drink milk after 2 to 3 hours, it is the peak of calcium exclusion through the kidneys, and at this time the body is in a state of sleep, the urine is concentrated, calcium through the kidneys more, so it is easy to form stones. 6, avoid strong tea, pickles: tea contains oxalic acid and tannic acid to promote stone formation, so stone patients are not recommended to drink a lot of strong tea for a long time. Pickles in the pickling process in high acidity, the oxalic acid contained in the gastrointestinal, will react with the calcium, produce calcium oxalate, the formation of urinary stones.
