Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive treatment option, which has the advantages of less pain for the patient, better treatment effect, wider applicability and fewer complications. Extracorporeal Shock Wave Lithotripsy is suitable for urinary stones, its working principle is to find the stone through ultrasound localization, the machine focuses on the stone, and then the ultrasound energy is released to break the stone, which is then discharged with the urine. Extracorporeal shock wave lithotripsy is mostly used for stones in the upper, middle and lower part of the ureter, which are less than one centimeter in diameter and can be repeated many times; there is no obvious contraindication to the body, and there is no obvious pain in the process of the operation, but only a slight discomfort. After lithotripsy, patients are advised to drink more water and do more exercise, such as climbing stairs and jumping rope, to accelerate the discharge of stones, so as to avoid the re-aggregation of stones and the emergence of obstruction. If there are urinary stones, it is recommended to go to the hospital as soon as possible to avoid delay.
