Reasons for Procedure
Lithotripsy is used to remove kidney stones that:
- Are too large to pass
- Cause constant pain
- Block the flow of urine (pee)
- Cause an ongoing infection
- Damage kidney tissue
- Cause bleeding
Possible Complications
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
- 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
Things that may raise the risk of problems are:
- Bleeding disorders or taking medicines that reduce blood clotting
- Chronic health problems, such as obesity
- Skeletal deformities
