Overview
Indications
These procedures are treatments for kidney stones that are used in patients with large or irregularly shaped kidney stones, people with infections, stones that have not been broken up enough by SWL (extracorporeal shock wave lithotripsy) or those who are not candidates for another common stone treatment, ureteroscopy. Stones that are bigger than 2 cm (the size of a marble) require this procedure.[1]
This is what the words mean:
- Percutaneous means through the skin
- Nephrolithotomy is a combination of the word roots nephro- (kidney), litho-(stone), and -tomy (removal)
- Nephrolithotripsy is a combination of the word roots nephro- (kidney), litho (stone), and -tripsy (crushed)[1]
Surgical procedure
Both procedures involve entering the kidney through a small incision in the back. Once the surgeon gets to the kidney, a nephroscope (a miniature fiberoptic camera) and other small instruments are threaded in through the hole. lf the stone is removed through the tube, it is called nephrolithotomy. lf the stone is broken up and then removed, it is called nephrolithotripsy. The surgeon can see the stone, use high frequency sound waves to break up the stone, and "vacuum" up the dust using a suction machine.[1]
