Both extracorporeal lithotripsy and minimally invasive have advantages and disadvantages. Extracorporeal shock wave lithotripsy is the simplest and most effective way to treat stones by breaking them up and discharging them out of the body through ultrasound positioning under ultrasound. Stones under 1.5 cm can be broken up and discharged through extracorporeal shock wave lithotripsy, which is less expensive and less invasive. Minimally invasive treatment is usually used when stones cannot be broken by extracorporeal shock wave lithotripsy, or when hydronephrosis is more serious and stones are larger. Minimally invasive is relatively more traumatic and more expensive, and it is a surgical treatment, so it is more dangerous than extracorporeal shock wave lithotripsy.
