Extracorporeal shock wave lithotripsy (ESWL) is a common non-invasive treatment for urolithiasis, and less commonly for pancreatic or salivary ductal stones 4. It is less successful in obese patients and with stones >2 cm. Children respond equally well or better to ESWL than adults 5.
The principle of extracorporeal shock wave lithotripsy is that focused shock waves cause stone fragmentation. Repetition of this process eventually leads to pulverization of the calculi. Radiologically these can be visualized during the treatment with either fluoroscopy or ultrasound imaging.

- abdominal aortic aneurysm
- use of anticoagulants, antiplatelets or some NSAID medications
