Lithotripsy is a way to treat kidney stones without surgery.
It is also called extracorporeal shock wave lithotripsy, or ESWL. This
treatment uses sound waves to break kidney stones into tiny pieces. These
pieces can then pass out of the body in the urine.
At the clinic
or doctor's office, you may get medicine to make you relaxed and help with pain
or discomfort. The doctor will use an X-ray to find the stone.
You will lie on a table, in most cases on top of a
water-filled cushion. The lithotripsy machine directs sound waves at your stone
through this cushion. After the machine starts, you may hear a popping sound
and feel a thump at your side. Do not move until you are told to do so. If you
have any pain, tell the doctor.
The doctor may use a small,
flexible tube called a stent. The doctor puts the stent inside the ureter. This is one of the tubes that takes urine from your
kidneys to your bladder. The stent will let the stone pass more easily.
Your doctor may remove
the stent in a few weeks.
Most people are at the doctor's office
or clinic for about 2 hours. You can go back to your normal routine right
Most stones pass within 24 hours after the procedure. But it can take as long as several weeks. If you have a large stone, you
may need to come back for several treatments. In some cases lithotripsy does
not break up the stones. Surgery may be needed to remove them.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor
if you are having problems. It's also a good idea to know your test results and
keep a list of the medicines you take.
Procedures can be stressful. This information will help you understand what you
can expect. And it will help you safely prepare for your procedure.
