Extracorporeal shock wave lithotripsy is a very safe procedure with few complications. However, minor complications do occur:
- For kidney stones, bleeding may occur around the kidney and, in some patients, this may rarely require a blood transfusion.
- Sometimes, when kidney and urinary tract stone fragments are being passed, urine flow from the kidney can be blocked. If this causes severe pain or blockage of the kidney, a tube may be placed through the back and into the kidney to keep the kidney drained until all the fragments pass out.
- Stone fragments are occasionally left in the body. This means that additional treatments are needed.
- An excessive urge to urinate, excessive blood in the urine, extreme pain, or other unusual symptoms, may indicate an infection or a blockage, and if any of these symptoms occur, you must contact your doctor immediately.
