Most people who have lithotripsy for kidney stones are free of stones within 3 months of treatment. Those with stones in the kidney and upper ureter have the most success with treatment. There may be fragments that are too large to pass after the procedure. They can be treated with lithotripsy again.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems, like:
Blood in the urine
Bruising in the back or abdomen
Pain as the stone fragments pass
Failure of stone fragments to pass, requiring additional surgery
Need for additional treatments
Reaction to anesthesia
Some factors that may increase the risk of complications include:
Bleeding disorders or taking medications that reduce blood clotting
The doctor will use previous tests to plan treatment. The care team will review your medicine before treatment. Some medicine may need to be stopped up to 1 week before the procedure.
Heavy sedation or
is usually used. Heavy sedation will keep you calm. General anesthesia will keep you asleep through the procedure.
Description of the Procedure
The technician will ask you to lie on top of a table. The table can slide back and forth, up and down or side to side to get you in the right position. There will be a device over the bed that shows the doctor where the stone is. The doctor will use the images to align the shockwave device to the stone. This device is under the bed. When it is in the right position it will send a shockwave that is targeted to the stone. They will be crushed into pieces as small as grains of sand.
How Long Will It Take?
45 to 60 minutes
How Much Will It Hurt?
Anesthesia prevents pain during the procedure. There may be some soreness or bruising over the area after the surgery. Home care and medicine can ease discomfort. There may be some pain and discomfort as the broken stones pass.
You will be able to move almost immediately after the procedure.

Extreme urge or inability to urinate
