Percutaneous nephrostolithotomy or pyelostolithotomy, with or without dilation, endoscopy, lithotripsy, stenting, or basket extraction; over 2 cm

AI EXPLANATION: Percutaneous nephrolithotomy (PCNL) is a minimally invasive surgical procedure used to remove large kidney stones, typically those larger than two centimeters. A surgeon makes a small incision in the patient's back to access the kidney with a miniature telescope and specialized instruments. The stones are then fragmented using targeted energy and removed through the incision, often followed by the temporary placement of a small drainage tube or internal stent to support healing.
