In recent years, with the improvement of people’s living standard, the optimization of dietary structure, a large amount of protein and fat being inhaled into the body, cholesterol saturation and precipitation, and the development of the aging trend and many other factors, the incidence of kidney stones has increased year by year. Nevertheless, there are still a considerable number of people who do not know enough about kidney stones, and many patients think that it does not matter much to have a small stone in their body, which is a very wrong understanding. Urinary stones can cause severe back pain, hematuria, fever, and even malignant changes and kidney function damage, and they are prone to recurrence. Kidney stones and hematuria are actually inseparable, and some patients do not have the typical clinical symptoms of pain from stone disease, but only seek medical attention because of hematuria. In this group of patients, if the primary cause of hematuria is not pursued and the relevant tests to diagnose stones are not performed, it is easy to ignore the existence of stones, causing delays in the diagnosis and treatment of the disease and serious damage to health.
