Urological stones include kidney stones, ureteral stones and bladder stones. They are a high incidence in urology, and the treatment of stones is closely related to size, location and comorbidities. The recurrence rate of urinary stones is reported to be high, up to 50% or more. There are many patients who think that everything is fine after stone surgery and usually do not pay attention to prevention and review, the stones may grow again, even bigger and more than before surgery, without realizing it! The fastest reported recurrence after surgery is one week to the preoperative state. So, what should we pay attention to in order to prevent stone regeneration? One of them is to drink more water. Adults should keep urinating about 2000-2500ml per day so that the stones are washed out by urine before they form particles. Patients with uric acid stones can drink more soda. Secondly, regular review of ultrasound, ultrasound has no adverse effects on the body and is inexpensive. It should be reviewed several times a year to detect small stones and deal with them in time so that they do not develop to the point of needing surgery. Other areas that need attention are not to drink alcohol, not to drink strong tea, less carbonated drinks, avoid high animal protein diet, purify water, etc. In addition to drinking more water, stone patients usually need to pay attention to the following points in their diet: Fruits: potassium citrate is an effective ingredient to inhibit stone formation, citrus fruits are rich in potassium citrate, stone patients can increase this type of food. Less salt: Limit your daily salt intake to 4-5 grams. More veggies, less meat: Eat more fruits and vegetables and fiber-rich foods, while controlling daily protein intake. Limit oxalic acid: Mangoes, spinach, sesame seeds, chocolate, nuts, and strong tea are all oxalic acid-rich foods and should be limited in intake. Limit purines: Patients with high uric acid should limit purine-rich foods, such as seafood and animal offal. At the same time, alcohol is metabolized to produce lactic acid, which promotes the deposition of uric acid, so patients with stones should limit alcohol. Reasonable calcium supplementation: 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.
