Extracorporeal lithotripsy, also known as extracorporeal shock wave lithotripsy, is a common method of treating ureteral stones or kidney stones, with the advantage of being non-hospitalized, simple and convenient. If the stone does not break down, it may indicate that the stone is hard, the stone is adherent to the mucosa, or the ureter is narrowed, etc. This would require hospitalization and surgical intervention with minimally invasive surgery. Depending on the condition, one can choose to insert a ureteral rigid or ureteral flexible mirror via the urethra and then remove the stone with laser lithotripsy or percutaneous nephrolithotripsy ultrasound lithotripsy, which means that the kidney is punctured in the lumbar region to establish a channel and insert a nephrolithotripsy to remove the stone.
