Lithotripsy

Definition

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.

Alternative Names

Extracorporeal shock wave lithotripsy; Shock wave lithotripsy; Laser lithotripsy; Percutaneous lithotripsy; Endoscopic lithotripsy; ESWL

Description

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.

Why the Procedure Is Performed

Lithotripsy is used to remove kidney stones that are causing:

  • Pain
  • Urinary tract infections
  • Bleeding
  • Harm to your kidney

Risks

Lithotripsy is generally safe. Ask your doctor about these possible complications.

  • Pieces of stone are left in your body. You may need more treatments.
  • Bleeding around your kidney may require a blood transfusion.
  • Your kidneys may not work as well, or they may stop working, after the procedure.
  • You may get ulcers in your stomach or small intestine.
  • Pieces of the stone may block urine flow from your kidney. This may cause severe pain or damage to your kidney.
  • Kidney infection may occur.

Before the Procedure

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.

On the day of your procedure:

  • You will usually be asked not to drink or eat anything for several hours before the procedure.
  • Take the drugs your doctor told you to take with a small sip of water.
  • Your doctor or nurse will tell you when to arrive at the hospital.

After the Procedure

After the procedure, you will stay in the recovery room for up to about 2 hours. Most people are able to go home the day of their procedure.

Outlook (Prognosis)

How well you do depends on the number of stones you have, their size, and where in your urinary system they are. Usually, lithotripsy completely removes the stones.
