Extracorporeal Shock Wave Lithotripsy (ESWL)


Extracorporeal shock wave lithotripsy is a non-invasive outpatient procedure. ESWL uses ultrasonic waves to break the stone(s) without any invasion of the body. Treated stone(s) need to be passed spontaneously with increased hydration via urination.

How to prepare for the procedure

Extracorporeal shock wave lithotripsy is performed under anesthesia. When preparing to have a procedure performed under anesthesia you can expect to start fasting the night prior to your procedure. Please consult with your surgeon to discuss the pre-operative testing which may include; blood work, chest x-ray, EKG, discontinuation of medications, and clearance for other medical reasons. The procedure will be done at the hospital or outpatient surgery center. Patient may be discharged home with a catheter that will remain in for a few days.
