There are many kinds of serious complications of extracorporeal lithotripsy, the most serious being kidney rupture, mainly caused by particularly hard stones, too much energy for lithotripsy, and too often. There is also damage to surrounding organs, such as kidney and surrounding tissue damage. Excessive accumulation of stones in the ureter during lithotripsy can cause stone streets, resulting in back pain or discomfort for the patient, sometimes combined with secondary infections, etc. Infectious stone patients may suffer from urinary tract infections and bacteremia due to the spread of bacteria in the stones, which often cause fever and even infectious shock in severe cases.
