Abstract

INTRODUCTION AND OBJECTIVES: It has been established that high intrapelvic pressures (IPP) may cause possible spread of infection through pyelo-venous backflow while lower pressures can hinder surgeon's visualization, decrease venous tamponade and result in increased bleeding. The purpose of this study is to characterize IPP during percutaneous nephrolithotomy. METHODS: A porcine model was utilized to test IPP during rigid and flexible nephroscopy. Pressures were compared in a variety of conditions including single versus two tract access, rigid versus flexible nephroscopy and presence versus absence of suction. Twenty trials were performed for each condition. An independent samples Mann- Whitney U test was used to compare parameters, with p
