Analysis of surgical and histopathological results of robot-assisted partial nephrectomy with use of three or four robotic arms: an early series results

ABSTRACT Objectives: The aim of this study was to evaluate whether criteria exist to guide election between the use the three- or four-arm technique in robotic partial nephrectomy (RPN) instead of just the surgeon’s preference. Material and Methods: We performed a retrospective review of 80 patients submitted to RPN from May 2016 to February 2020.
