Lithotripsy is a 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.
Description
Extracorporeal shock wave lithotripsy (ESWL) is the most common type of lithotripsy. "Extracorporeal" means outside the body.
To get ready for the procedure, you will put on a hospital gown and lie on an exam table on top of a soft, water-filled cushion.
You will be given medicine for pain or to help you relax before the procedure starts. You will also be given antibiotics.
When you have the procedure, you may be given general anesthesia for the procedure. You will be asleep and pain-free.
High-energy shock waves, also called sound waves, guided by x-ray or ultrasound, will pass through your body until they hit the kidney stones. If you are awake, you may feel a tapping feeling when this starts. The waves break the stones into tiny pieces.
The lithotripsy procedure should take about 45 minutes to 1 hour.
A tube may be placed through your bladder or back into your kidney. This tube will drain urine from your kidney until all the small pieces of stone pass out of your body. This may be done before or after your lithotripsy treatment.
Why the Procedure Is Performed
Lithotripsy is used to remove kidney stones that are causing:
- Bleeding
- Damage to your kidney
- Pain
- Urinary tract infections
Not all kidney stones can be removed using lithotripsy. The stone may also be removed with:
-
A
tube
(endoscope) inserted into the kidney through a small surgical cut.
Tube
Percutaneous (through the skin) urinary procedures help drain urine from your bladder and get rid of kidney stones.

- Open surgery (rarely needed).
Risks
Lithotripsy is safe most of the time. Talk to your health care provider about possible complications such as:
- Bleeding around your kidney, which may require you to get a blood transfusion
- Kidney infection
- Pieces of the stone block urine flow from your kidney (this may cause severe pain or damage to your kidney)
- Pieces of stone are left in your body (you may need more treatments)
- Ulcers in your stomach or small intestine
- Problems with kidney function after the procedure
Before the Procedure
Always tell your health care provider:
- 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 blood thinners such as 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 provider which drugs you should still take on the day of the surgery.
On the day of your procedure:
- You may not be allowed to drink or eat anything for several hours before the procedure.
- Take the drugs you have been told to take with a small sip of water.
- You will be told 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 . You will be given a urine strainer to catch the bits of stone passed in your urine.

Outlook (Prognosis)
How well you do depends on the number of stones you have, their size, and where in your urinary system they are. Most of the time, lithotripsy removes all the stones.

The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and stimulating red blood cell production.

Nephrolithiasis - illustration
Kidney stones result when urine becomes too concentrated and substances in the urine crystalize to form stones. Symptoms arise when the stones begin to move down the ureter causing intense pain. Kidney stones may form in the pelvis or calyces of the kidney or in the ureter.

In the procedure intravenous pyelogram (IVP), the patient is injected with radiopaque dye and X-rays are taken as the dye travels through the urinary tract. This procedure is performed to confirm the presence of kidney stones, although some stones may be too small to see.

Lithotripsy procedure - illustration
Extracorporeal shock wave lithotripsy (ESWL) is a procedure used to shatter simple stones in the kidney or upper urinary tract. Ultrasonic waves are passed through the body until they strike the dense stones. Pulses of sonic waves pulverize the stones, which are then more easily passed through the ureter and out of the body in the urine.
