About PCNL (Percutaneous Nephrolithotomy)
Percutaneous Nephrolithotomy (PCNL) is the preferred treatment for large or complex kidney stones. Through a small puncture in the back, a scope is passed directly into the kidney to break and remove the stone.
It provides high stone clearance with much faster recovery than open stone surgery.
