PERCUTANEOUS NEPHROLITHOTRIPSY – PCNL
Percutaneous Nephrolithotripsy – PCNL
This surgical procedure is performed under local anesthesia and intravenous sedation. Percutaneous (through the skin) removal of kidney stones is accomplished through the most direct route to stones through the kidney. A needle and guidewire are used to access the stones. The surgeon then threads various catheters over the guidewire and into the kidney and manipulates surgical instruments through the catheters to fragment and remove kidney stones. This procedure achieves a better stone-free outcome in the treatment of medium and large stones than shock wave lithrotripsy. This procedure usually requires hospitalization, and most patients resume normal activity within 2 weeks.
