When a patient has stones, if the stones are less than 6mm in diameter, they can be expelled through conservative treatment, so the stones are expelled through the urinary system. If the stone is located in the kidney or in the ureter, Holmium laser lithotripsy with ureteroscopy is performed to pulverize the stone into powdered granules, and the stone is also treated by eliminating the stone through the normal urinary tract system. However, for larger stones, such as cast stones, percutaneous nephrolithotomy holmium laser lithotripsy is required. In this case, the stone is flushed out of the operating sheath through the percutaneous nephroscope’s lithotripsy suite during the pulverization process. Therefore, in this case, the stones are flushed out of the body by the operating instruments, but some of the remaining powdered stones are also discharged through the urinary system after the operation by constant exercise, drinking plenty of water and urinating regularly, so the process of stone discharge is mainly determined by which treatment is chosen.
