Endoscopic extracorporeal lithotripsy is a surgical treatment method, usually applied to kidney stones less than 15 mm in size or ureteral stones in the upper third with size less than 10 mm.
1. What is extracorporeal lithotripsy?
It is a universal treatment for urinary stones that most medical facilities can perform. This method uses magnetic waves generated by the lithotripsy machine to penetrate the skin to focus on the stone and break the stone into many small pieces, then the stone is excreted in the urine. Most patients need more than 1 time to get rid of the stone.

The doctor applies a layer of ultrasound gel to the skin on the side of the ribs corresponding to the location of the lithotripsy. The nurse helps the patient wear noise-cancelling headphones to make them more comfortable when hearing the "pop" sound during the lithotripsy. When the patient is in a really comfortable position, the doctor and nurse will perform an extracorporeal lithotripsy procedure for the patient. Patients will be placed intravenous lines and injected with pain relievers, anti-bleeding drugs 30 minutes before lithotripsy.
