When stones are present in the body, if they are not excreted for a long time and remain in the kidney for too long, they will gradually increase in size. Because there are salts in the urine, if they come into contact with the surface of the stone, they will continuously settle, thus causing the stone to gradually grow in size, and the patient needs timely examination and treatment. If the stones are less than 6 mm in diameter, they can be treated conservatively by drinking more water, urinating more often, and exercising longitudinally, which can facilitate the discharge of stones. If the stone diameter is larger, extracorporeal shock wave lithotripsy can be performed, and if the stone can be crushed into powder, it can also be treated by conservative stone removal. If extracorporeal shock wave lithotripsy fails, ureteroscopic holmium laser lithotripsy or percutaneous nephrolithotripsy is also required to completely expel the stones and prevent them from remaining in the body for a long time, forming stone growth centers and growing.
