Urinary stones can be divided into upper urinary tract (kidney, ureter) stones and lower urinary tract (bladder, urethra) stones according to the location of the stones. The common symptoms of upper urinary tract stones are sudden onset of lower back pain, which may be accompanied by hematuria, fever and other symptoms. The hydronephrosis caused by stone obstruction can lead to impaired kidney function, so they receive more attention from clinicians and are more difficult to treat than lower urinary tract stones. Currently, the majority of patients can be treated satisfactorily with minimally invasive surgery. With the high prevalence of stones and the recurrence rate of calcium-containing stones being as high as 30-40%, is there anything we can do to make many patients suffer less from recurrence? An exciting phenomenon is that the recurrence rate of stones can be reduced by 50% through health education by the doctor at the time of the patient’s visit. This is known as the “stone-visit effect”. So what is the magic bullet that works so well? In fact, it is very simple, is how urinary stones patients should eat healthy? 1, drink water: no matter what the composition of the stone, the primary way to prevent recurrence is to drink more water. At present, the exact cause of stones is not conclusive internationally. But one thing is recognized, is that the formation of stones in the urine is oversaturated with ingredients, and inhibit the formation of stones is too little. One of the easiest and most effective ways to change this is to drink more water and increase the total volume of urine, thereby diluting the stone promoting components in the urine. And whether drinking enough water depends on the amount of urine: the same daily intake of 3000 ml of water may end up producing 1500 ml of urine for heavy workers because of sweat loss, while light workers produce 2500 ml of urine. The former then has a much higher chance of forming stones than the latter. Therefore, regardless of the amount of water consumed, you should end up with a daily urine volume of 2000-2500 ml. Most stones are acidic stones, so alkalizing the urine can inhibit the growth of such stones, and the most common drink is soda. 2, fruit: potassium citrate is an effective ingredient to inhibit stone formation, and the daily diet, citrus fruits are rich in potassium citrate, stone patients can increase this type of food; and for infectious stones, because acidic urine can inhibit the growth of bacteria, so you can eat more apples, cranberries and other acidic fruits. 3. Less salt: Excessive salt intake will increase the concentration of sodium in the blood, thus prompting the kidneys to excrete more calcium, which will eventually deposit calcium-containing stones. The daily salt intake should be controlled at 4-5 grams. 4, more vegetarian and less meat: high calorie and high protein diet can increase the prevalence of stones, so for stone patients, they should eat more fruits and vegetables and fiber-rich foods, while controlling the daily protein intake. 5, limit oxalic acid: calcium oxalate is the most common type of stone, limit oxalic acid-rich food, can reduce the recurrence rate of these stones, daily diet, mango, spinach, sesame, chocolate, nuts, strong tea, etc., are rich in oxalic acid food, should limit the intake. 6, limit purine: high purine diet will increase the concentration of uric acid in the urine, uric acid is not only easy to form uric acid stones, but also cause an acidic environment in the urine, increasing the chances of the formation of other acidic stones. Therefore, patients with high uric acid should limit purine-rich foods, such as seafood and animal offal. At the same time, alcohol will generate lactic acid after metabolism, promoting the deposition of uric acid, so patients with stones should limit alcohol. 7. Reasonable calcium supplementation: Many stone patients are afraid to take calcium supplements for fear of calcium salt deposition and stone formation. In fact, according to research, reasonable calcium supplementation does not increase the formation of stones. The amount of calcium supplement suitable for national people is 800mg/day. As the saying goes, disease enters through the mouth. And a clear stone composition and reasonable diet can greatly reduce the recurrence rate of stones.
