After kidney stone surgery, there is still a possibility of stone recurrence. Kidney stone surgery only removes all the existing stones in the body, after the removal, as long as the kidneys have the function of urination, stones will still form in the urine under pathogenic conditions, for example, if the concentrated state of urine is not improved for a long time, the concentration of the components in the urine is too high, it will be supersaturated and precipitated to form crystals, and then form stones. If the patient still has dietary preferences, such as the prolonged application of large amounts of seafood, animal offal, or the use of acidic substances, such as a prolonged meat diet, an excessively salty diet, or a high-fat diet, the probability of stone formation can be increased. Patients with metabolic abnormalities that only remove stones but not the associated diseases, such as hyperparathyroidism, can form stones in the urine even if the stones are removed from the body and the original disease is not removed. After kidney stone surgery, there is still a probability of recurrence. After surgery, we should pay attention to prevent urine concentration, adjust the diet structure, and deal with chronic diseases that cause stones in order to achieve the possibility of reducing the probability of recurrence.
