PCNL: What is a percutaneous nephrolithotomy?

What is a percutaneous nephrolithotomy or PCNL? Dr. Daniel Reznicek describes why a PCNL is performed and what to expect from the procedure. (https://www.pacificnorthwesturology.c.... A percutaneous nephrolithotomy is a procedure performed by a urologist to treat large or complex kidney stones. In the procedure, the urologist gains access to the kidney through the skin (percutaneously) and then uses instruments to crush and then remove the stones. Stones that are larger than 1.5cm or in difficult locations to reach by a ureteroscope are ideally suited for a PCNL. In the procedure, the urologist is able to use larger instruments and remove a much larger volume of stone compared to other surgical methods. It is important to see a urologist who is familiar with the procedure because it does come with higher risks than a ESWL or ureteroscopy and is a more complex procedure. In high volume centers, complication rates are quite low. Some urologists perform the procedure with the help of an interventional radiologist to help enter the kidney, often requiring a separate procedure and anesthetic. Preferably, this is performed by the urologist at the time of the procedure to minimize the need for multiple anesthetics. Access into the kidney is performed by a combination of fluoroscopy (X ray), and sometimes ultrasound guidance. The urologist closely examines prior CT imaging to make sure that the kidney is accessed sa
