In percutaneous nephrolithotomy or nephrolithotripsy, the surgeon makes a small incision in your back to remove kidney stones. He or she then puts a hollow tube into your kidney and a probe through the tube. In nephrolithotomy, the surgeon 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.
See a picture of nephrolithotomy.
What To Expect After Treatment
You will be in the hospital for at least 2 to 3 days. Most people are able to return to work within a few weeks.
Why It Is Done
This procedure may be used to treat kidney stones that are:
- Larger than 2 cm (0.8 in.) in diameter.
- Large and caused by an infection (staghorn calculi).
- Blocking the flow of urine out of the kidney.
- Not broken up by extracorporeal shock wave lithotripsy (ESWL).
How Well It Works
These procedures work for most people with stones in the kidney or ureter.
Risks of this procedure include:
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 the procedure.
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.
