Urinary calculi can be divided into two types: upper urinary calculi and lower urinary calculi. Among them, upper urinary calculi include: kidney calculi, ureteral calculi. Lower urinary tract stones include bladder stones and urethral stones. Generally speaking, the factors of urinary calculi are very complicated, including genetic factors, familial factors, drinking water factors, physical complications and other diseases. Even environmental factors are related. For example, in southern China, the incidence rate is actually higher than that in northern China, which is a common phenomenon. Of course, some cases may be related to nutritional factors. In short, there are many reasons for the formation of urinary calculi. Generally, when looking for the causes of urinary calculi, we will advise patients to do a composition analysis of urinary calculi, and understand the specific reasons for the formation of calculi according to the composition analysis of calculi, as well as some means and measures for timely prevention in the future. If there is no condition for chemical analysis of stones, it is suggested that patients develop the habit of drinking more water. And be sure to add a lot of water after exercise. In addition, it is suggested that patients should have a balanced nutritional status. If stones occur repeatedly for some special medical records, patients will also be advised to do some other disease tests. Therefore, for a stone problem, it usually needs to be considered comprehensively and analyzed emphatically. Of course, calculus is not a rare disease. For this disease, don't be afraid. If you encounter problems, just consult a specialist, cooperate and treat them.
