Extracorporeal Shock Wave Lithotripsy (ESWL) is an advanced, non-invasive technique used by urologists to break up certain types of kidney stones. This case is performed at an ambulatory surgery center under general anesthesia.
Among treatments for kidney stones, Extracorporeal Shock Wave Lithotripsy (ESWL) is the most common treatment in the U.S. Shock waves emanating from a special, FDA-approved device are directed from outside the body. These shock waves case the kidney stones to fragment into tiny pieces.
This procedure is sometimes called ESWL: Extracorporeal Shock Wave Lithotripsy®.
These are what the words mean:
– extracorporeal: deriving from outside the body
– shock waves: pressure waves applied to the body
– lithotripsy (the Greek roots are “litho” means stone, “tripsy” means crushed)
ESWL is a non-invasive technique for treating stones in the kidney or ureter (tube going from the kidney to the bladder) using high-energy shock waves produced by a specialized device. The resulting fragments are very small, much like dust and are small enough to pass during urination. lf the treatment leaves any large pieces, your doctor may need to perform another treatment.
Non-invasive techniques or treatments are far safer than invasive treatments. The goal is always to eliminate the underlying problem, in this case a stone, that is causing pain and presents a risk for infection.
