What is Percutaneous Nephrostolithotomy?

Percutaneous Nephrostolithotomy is a complex procedure during which large amounts of kidney stones generally greater than 2.5 cm are removed from the kidney. Percutaneous Nephrostolithotomy is performed with the patient generally in the prone position, and is accomplished first by establishing access into the kidney through the back, then the access track is dilated. Next the stones are pulverized and removed. Once concluded, the urologist may decide to leave a tube that exits the kidney and through the flank.

The risks of Percutaneous Nephrostolithotomy are several and include bleeding, infection, sepsis, and risks of anesthesia. Dr. Kamyar Ebrahimi who has performed many of these procedures, explains that although the incision of this procedure is very small, usually 2 cm, the impact on the patient could be tough, and the patient has to be able to withstand this procedure. Nonetheless, Percutaneous Nephrostolithotomy is an excellent means of treating large volume stones in patients with large kidney stones.
