What is PCNL for kidney stones?

PCNL stands for percutaneous nephrolithotomy, a surgery that removes a stone directly from the kidney. For a large stone (10 mm to 20 mm or more), it can be faster and easier for you if the surgeon goes directly from your back into the kidney to take out the stone, avoiding the ureter. For very large stones (often called "staghorn stones") that fill the entire hollow part of the kidney, several PCNL procedures might be needed to remove all the pieces of the stone.
