Introduction and background: Since advent, percutaneous nephrolithotomy (PCNL) remains one of the primary armamentarium of surgical management of stone disease. Tract dilatation in PCNL can be done either by serial dilatation or by ‘one-shot’ single step method. This study intends to find out the feasibility of ‘one-shot’ single step tract dilatation. Materials and method: Total 188 patients’s undergone PCNL meeting inclusion and exclusion criteria were randomized into two groups from January, 2017 to December, 2018. Group A (serial tract dilatation) and group B (one-shot single step dilatation) included 112 and 76 patients respectively. Length of time of dilatation of tract, X-Ray exposure time, total operative time and perioperative blood transfusion were noted. Any complications were kept into account in both groups. Result: Epidemiological profile of the patients and stone characteristics were equivalent between group A and group B. Mean operative time, mean access tract dilatation time, mean total fluoroscopy time and mean postoperative hospital stay were significantly less in group B. Stone free rate, requirement of blood transfusion, post operative pain score and complications rate were similar between both groups. Discussion and conclusion: Single step dilatation of PCNL tract is a safe, time saving and effective technique. Judicious application of this procedure in expert hand demonstrates high stone free rate following PCNL.
