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.

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.

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.
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.
