Extracorporeal shock wave lithotripsy (ESWL) is one way to treat kidney stones. ESWL is used to break up kidney stones located anywhere in the urinary system. ESWL is an outpatient procedure done in the hospital or surgery center and patients are given intravenous anesthesia. The stone is broken up into tiny granules that can be passed in the urine. For larger stones, several ESWL treatments may be required.
Ureteroscopy is one way to treat kidney stones. A ureteroscope (a thin telescope type instrument) is used to eliminate kidney stones located in the ureter. It is an outpatient procedure done in the hospital or surgery center and performed usually under general anesthesia. A laser fiber is placed through the ureteroscope and is used to break up the kidney stone. The stone may also be removed by a basket.
