What is PCNL?

Percutaneous Nephrolithotomy

PCNL is a technique used to remove certain stones in the kidney or upper ureter (the tube that drains urine from the kidney to the bladder) that are too large for other forms of stone treatment. Kidney stones are solid crystals formed from the salts in urine. They are sometimes called renal calculi. They can block the flow of urine and cause infection, kidney damage or even kidney failure.
