The preferred treatment for kidney stones of 1cm, which are smaller stones, is extracorporeal shock wave lithotripsy. Extracorporeal shock wave lithotripsy treatment is safe and effective, and is the preferred treatment for stones up to 2cm clinically. The stones are broken up by extracorporeal shock wave lithotripsy and can be expelled from the body on their own. After extracorporeal shock wave lithotripsy, patients should pay attention to drink more water, urinate more often and move around appropriately to help promote the excretion of residual stones as soon as possible. During the process of urination, it is important to observe whether any stone fragments are discharged. In addition, stones can be discharged into a fixed container, which helps to observe whether stones are discharged or not. If the stone is found to be discharged, it is also necessary to review the abdominal plain to observe whether the stone has been discharged.
