ESWL: Extracorporeal Shock Wave Lithotripsy®. Shock waves are administered under X-ray guidance to the kidney stone while the patient is under general anesthesia. The stone is broken up in to tiny fragments and particles that will then pass through the urine over the next few days to week. Sometimes a ureteral stent is placed at the same time as the ESWL procedure to assist in passing fragments.



A small scope is passed into the bladder and then into the ureter or kidney where the stone is. A tiny laser is then used to break up the stone into tiny fragments and particles, which are then removed. Usually a ureteral stent is placed temporarily at the end of the procedure to assist with post-operative swelling. This is a minor, outpatient procedure done under sedation.
