For 0.6cm kidney stones, it is recommended to drink more water and urinate more often, and regular clinical observation is sufficient, and temporarily no medication, extracorporeal shock wave lithotripsy or surgery can be used. In most cases, the stone can enter the ureter and be discharged into the bladder through ureteral peristalsis or urine flushing, but there may be pain in the back and abdomen during the process of discharge. In some patients, the stone stays in the ureter or does not enter the ureter and stays in the kidney for a long time. After lithotripsy, the size of the stone will be reduced and most of the stones can be excreted by drinking more water and urinating more often. If the stone stays in the kidney for a long time, extracorporeal shock wave lithotripsy can also be considered, and after lithotripsy, drink more water and observe the stone discharge.
