In this video, we explain in a clear and visual way what percutaneous nephrolithotomy (PCNL) is. This is a minimally invasive surgical procedure used to remove kidney stones and, in some cases, stones located in the ureter. PCNL is performed under general anesthesia and allows direct access to the kidney through a small incision in the skin. Using a needle, a dilator, and a nephroscope, the specialist can fragment the stones with a laser or remove them completely, ensuring an effective cleaning of the urinary system. In certain cases, catheters or a temporary stent are placed to guarantee proper urine drainage after surgery.
