ESWL uses shock waves to break a kidney stone into small pieces that can more easily travel through the urinary tract and pass from the body. Procedure performed in the hospital on an outpatient basis.
During the procedure:
- You lie on a water-filled cushion, and the surgeon uses X-rays to precisely locate the stone. High-energy sound waves pass through your body without injuring it and break the stone into small pieces. These small pieces move through the urinary tract and out of the body more easily than a large stone.
- The process takes about 45minutes; total hospital time varies between 2-3 hours.
After the hospital:
- It may take a few days or weeks for all the stone fragments to pass from your body.
- You may have mild discomfort on your side from the treatment it self or as small fragments pass through the urinary tract. Extra strength Tylenol should be effective.
- Drink plenty of fluids (especially water) daily to assist your system in expelling stone fragments.
- The office will call to set up a follow up visit with a KUB (x-ray of your Kidneys, Bladder and Ureters) prior to the visit.
