Percutaneous Nephrolithotripsy (PCNL)

Percutaneous nephrolithotripsy refers to a minimally invasive endoscopic treatment that is used for removing large kidney stones or multiple stones in the upper ureter. Percutaneous stone surgery may also be recommended in certain conditions where the ureter underneath one of the kidneys is obstructed.

In this process, a puncture is created in the skin through the kidney to the stone and a telescopic port is inserted. A nephroscope is passed through this port into the kidney to break up the stone into pieces and to remove the debris from the stone. PCNL is performed under general anesthesia and real-time x-ray control known as fluoroscopy.


The major benefits of PCNL are:

  1. It eliminates the need for large skin incisions.
  2. It removes the large incisions on the kidney or renal pelvis.
  3. Recovery and healing is faster when compared to other procedures.
  4. Shorter hospital stay
