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, 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.
