Percutaneous nephrolithotripsy

Diagram of PCNL

Percutaneous stone surgery is usually used for larger stones. A small hollow tube is placed directly through a patient’s back into the kidney through which larger instruments can then be used to fragment and extract the stone(s). Although this approach typically requires a hospital stay and is more invasive than ureteroscopy or extracorporeal shockwave lithotripsy, it is often the most effective method for treating  large stones quickly and completely. For more information on comparing the surgical options for kidney stones, see our comparison chart.

Percutaneous stone surgery may also be indicated in certain situations where the ureter below a  kidney is obstructed, such as in ureteropelvic junction obstructions, where a ureteroscope cannot be advanced from below.

    Just went through surgery last night for basic ureteroscopy and (I’ve begged a decade ago to remove the smaller stones, bUT they refused cuz they “may or may not pass”) now I find out after the surgery I have big stones that could not be blasted. I’m so over this stent burning everytime a pee! It’s like pissing lava or razors. Worst part I’d waking up and not falling back asleep due to the shock and pain the pee sends through your body. I can’t imagine a cath. I wish I was born without pain receptors just so I don’t feel pain.
