Lithotripsy procedure

Nephrolithiasis

Lithotripsy is a medical procedure that uses shock waves to break up stones in the kidney, bladder, or ureter (tube that carries urine from your kidneys to your bladder). After the procedure, the tiny pieces of stones pass out of your body in your urine.

Extracorporeal shock wave lithotripsy (ESWL) is the most common type of lithotripsy. "Extracorporeal" means outside the body.

You will wear a medical gown and lie on an exam table on top of a soft, water-filled cushion. You will be given a mild sedative or pain medicine before the procedure starts. You will also be given antibiotics before the procedure starts to prevent infection.

High-energy shock waves, also called sound waves, will pass through your body until they hit the kidney stones. You may feel a tapping sensation when this starts. The waves break the stones into tiny pieces.

The lithotripsy procedure generally takes 45 minutes to 1 hour.

A tube may be placed through your back and into your kidney. This tube will drain urine from your kidney until all the small pieces of stone pass out of your body. The tube may be put in place before or after your lithotripsy treatment.

Always tell your doctor or nurse:

• If you are or could be pregnant
• What drugs you are taking, even drugs, supplements, or herbs you bought without a prescription

During the days before the surgery:

• You may be asked to stop taking aspirin, ibuprofen (Advil, Motrin), warfarin (Coumadin), and any other drugs that make it hard for your blood to clot. Ask your doctor when to stop taking them.
• Ask your doctor which drugs you should still take on the day of the surgery.
