nephrolithotripsy, the surgeon makes a small incision in your back to remove
kidney stones. He or she then puts a hollow tube into

removes the stone through the tube. In nephrolithotripsy, he or she breaks the
stone up and then removes the fragments of the stone through the tube.
If you've had a kidney stone once, you're at an increased risk for another one. A urologist is frequently involved in deciding whether you'll need an extensive medical evaluation, including testing the amounts of various minerals in your urine, to assess further risks of stone formation.
If your kidney stone is small, it may pass out of your body on its own within a few days or weeks. Your health care provider will likely ask you to drink lots of water -- 2 to 3 quarts a day -- and prescribe a pain...

Risks of this procedure include:
Holes (perforation) in
the kidney. They usually heal without further treatment.
other abdominal organs, such as the
Damage that affects normal kidney
What To Think About
A stone that has left the kidney may need to be pushed
back into the kidney with a small tool (ureteroscope) before the surgeon can do
These procedures are used more frequently than
extracorporeal shock wave lithotripsy (ESWL) to remove larger stones, such as
staghorn calculi. Every fragment of a staghorn calculus must be removed to
prevent the stone from returning.
