How big of a kidney stone can be treated with extracorporeal shock wave lithotripsy?

Patient's question:

My father was diagnosed with a 1.2cm kidney stone at the hospital. I want to ask how to treat it effectively? Can it be treated with extracorporeal shock wave lithotripsy (ESWL)?

Doctor's answer:

Generally, if there are no other limiting factors for patients with kidney stones, those with stones between 0.5 cm and 2 cm in size can undergo extracorporeal shock wave lithotripsy (ESWL). The Swiss EMS LithoClear system is currently one of the most widely used kidney stone treatments internationally. Its most unique feature is the ability to fragment and clear stones simultaneously, completely eliminating the issue of incomplete stone removal.
The EMS LithoClear system treats kidney stones in just 10–15 minutes, thoroughly clearing the stones from the patient's body. The entire process is safe and painless! A tiny incision is made on the patient's waist, through which the lithotripsy instrument is inserted. This allows for simultaneous stone fragmentation and rapid removal of the fragments, delivering immediate therapeutic results.
