In the clinic to do extracorporeal lithotripsy usually takes about 30 minutes, extracorporeal lithotripsy refers to the use of extracorporeal shock waves, the body’s stone broken, which belongs to the indirect lithotripsy method. Compared with minimally invasive surgery, extracorporeal lithotripsy is less effective. Lithotripsy can be categorized into imported equipment and domestic equipment. Generally, the lithotripsy effect of imported equipment is better than that of domestic lithotripsy equipment. Extracorporeal lithotripsy is generally used for kidney stones less than 2cm and ureteral stones less than 1.2cm. If the stone is larger than this, it is generally not recommended to do extracorporeal lithotripsy because the lithotripsy effect is not good for too large stones.
