Left and right kidneys in person's back, with detail inside kidney showing kidney stone broken into pieces and being removed through tube.

Percutaneous nephrolithotomy and nephrolithotripsy are procedures in which a small incision is made in a person's back to remove kidney stones. In both cases, the doctor puts a tube into the kidney and a scope through the tube. In nephrolithotomy, the doctor removes a stone through the tube. In nephrolithotripsy, the stone is broken up and the fragments of the stone are removed through the tube.
