Extracorporeal shock wave lithotripsy is a very common method used clinically to treat kidney and ureteral stones. Extracorporeal shock wave lithotripsy is used to break up stones under the action of high-frequency focused ultrasound, so as to eliminate them from the body, and this method is almost non-invasive to the human body and is widely used in clinical practice. For slightly larger stones, one lithotripsy may not be completely successful, and two or three lithotripsy sessions can be performed. For extracorporeal shock wave lithotripsy patients, the selection must be careful, the patient should not be too obese patients, no spinal deformity, and the distal end of the stone does not exist in the case of urinary obstruction, only then can lithotripsy be successful.
