Minimally Invasive Tract in Percutaneous Nephrolithotomy for Renal Stones

Abstract

Mini-PCNL is safe and effective for managing renal calculi in adult patients. Although smaller working sheath is associated with longer operative time, Mini-PCNL has significantly lower incidence of bleeding necessitating transfusion and higher stone-free rate for multiple caliceal stones in comparison with the standard PCNL.
