The most common sequelae after ureteral extracorporeal lithotripsy is that large stones become small stones, forming the so-called stone street, which leads to a piece of stone can not be discharged, resulting in the patient’s urine can not flow down smoothly, and the patient will experience back pain and fever, so extracorporeal lithotripsy has a certain requirement for the size of ureteral stones. In addition, the upper ureteral stone, near the renal pelvic-ureteral junction, the kidney may be damaged by extracorporeal shock wave lithotripsy after lithotripsy, so if the energy is too large or the frequency is too much, it will lead to kidney damage, and in serious cases, even kidney rupture can occur.
