Lithotripsy (Extracorporeal Shock Wave Lithotripsy ESWL®) is a noninvasive procedure which safely and effectively “shatters” your kidney stone without surgery, using an energy source outside your body. Shock waves are aimed directly at your stone, making it crumble into sand like particles, which then pass easily through your urinary tract.
You lie on a water-filled cushion, and the Urologist uses X-ray or ultrasound to precisely locate the stone. High-energy sound waves pass through your body and break the stone into small fragments. These fragments move through the urinary tract and out of the body more easily than a large stone.
- The procedure takes about an hour.
- You will receive anesthesia during your procedure.
- Your Urologist may use a stent. A stent is a thin flexible tube that dilates the ureter. This helps the stone fragments to pass without blocking the ureter.
