During the Procedure
Lithotripsy is usually performed on an outpatient basis or as part of your stay in the hospital. Procedures may vary depending on your condition and you and your doctor’s practices.
Generally, lithotripsy follows this process:
• You will be asked to remove any clothing, jewelry, or other objects that may interfere with the procedure.
• If you are asked to remove clothing, you will be given a gown to wear.
• An intravenous (IV) line will be inserted in your arm or hand.
• You may receive a sedative or anesthetic agent to ensure that you remain still and pain-free during the procedure.
• After the sedation has taken effect, you will be positioned on a water-filled cushion or immersed in a water-filled tub.
• After the stone(s) has been located with fluoroscopy or ultrasound, you will be positioned for the most direct access to the stone.
• If you are awake during the procedure, you may experience a light tapping feeling on your skin.
• A sequence of shock waves will be created to shatter the kidney stone(s).
• The stone(s) will be monitored by fluoroscopy or ultrasound during the procedure.
• A stent may be placed in the ureter to help the stone fragments (gravel) pass.
• Once the stone fragments are small enough to pass through the urinary system, the procedure will end.
