Kidney stones are important lesions even if they are occasionally painful. It is recommended to go to the hospital for examination and use active treatment measures to remove the stones. If kidney stones are mistaken for occasional pain that is not serious, there is a risk that the stones will gradually increase in size leading to a gradual increase in the amount of hydronephrosis and eventually irreversible damage to kidney function. Therefore, clinically, it is often seen in more acute pain, and patients are more likely to go to the hospital for consultation to remove the related disease instead. But for painless or painless disease, it often leads to further aggravation of the disease, and even organ failure. When there are kidney stones causing pain, it is often due to obstruction caused by the stones that the kidneys become dysfunctional in filtration and drainage, so that a small amount of urine accumulates in the kidneys, causing an increase in pressure in the renal pelvis, which causes symptoms such as hidden pain or severe pain. If the cause of the disease is not treated and the stones are not removed, the fluid in the kidney will increase and grow, leading to damage to the kidney parenchyma over time. The kidney function will be irreversibly damaged, which will gradually lead to renal insufficiency until the final stage of kidney failure, so it is an important disease that needs to be treated immediately in a hospital.
