COMPARISON BETWEEN SUPINE POSITION VERSUS PRONE POSITION IN PERCUTANEOUS NEPHROLITHOTOMY: A SINGLE CENTERED ANALYSIS OF 623 CASES

Background: The ideal urological method for treating complex, large renal calculi is Percutaneous nephrolithotomy (PCNL). Its instruments, surgical techniques, and positions have all been adjusted as a result of its ever-changing nature. In PCNL, the supine position is advantageous compared to the prone position due to its several advantages, including the absence of cardiopulmonary risks, fewer post operative complications and shorter operative time. This study was designed for comparison of PCNL in prone and supine positions. Methods: After receiving ethical and research committee approval, this retrospective cohort study (comparative study?) was conducted from 2015 to 2021. Out of 623 patients, PCNL in prone position was performed on 258 patients and 365 patients in modified supine position. The patients' demographics, stone size and location, number of tracts, operating time, hospital stay, stone clearance rate, and post-operative complications were all compared. Results: The gender and age of the patients, the size and number of tracts, and location of the stones were all comparable (p>0.05). Operative time for prone position was 82 min±2.49 SD VS 65 min±2.95 SD, for modified supine position, p
