Abstract

Retrospective analysis comparing the efficacy and surgical outcome between modified Supine PCNL and Prone PCNL in patients with renal calculi. Materials and Methods: Comparison of Efficacy between modified Supine PCNL vs Prone PCNL in terms of stone free rates (SFR) and comparison of surgical outcomes between modified supine PCNL vs Prone PCNL in terms of mortality, morbidity, radiation exposure, duration of hospital stay. The study involved 100 patients who underwent percutaneous nephrolithotomy (PCNL) at our facility between April 2019 and March 2020. The patients were randomly assigned to two groups of 50, with the first group undergoing PCNL in a modified supine position and the second group undergoing prone PCNL. A comparison between the radiation exposure, operative time, puncture attempts, duration of hospital stay ,stone free rates and complications were made. Results: There were no differences in number of punctures, stone free or complication rates between both the groups. However, the modified supine group had lesser operative time, lower mean radiation exposure and a brief hospital stay. Conclusion: Modified supine PCNL is just as safe as conventional prone PCNL, but it requires far less radiation and requires less time to complete the procedure
