Association of robotic partial nephrectomy for clinical T2a renal mass with improved trifecta outcome compared to open partial nephrectomy: A single surgeon comparative analysis.

653 Background: We compared surgical quality and functional outcomes of robotic partial nephrectomy (RPN) and open PN (OPN) for cT2a renal masses (cT2aRM). Methods: Retrospective analysis of 150 consecutive patients [RPN 59/OPN 91] from 6/2008 to 6/2016. Main outcome was achievement of Trifecta [negative surgical margin, no major urologic complications, and ≥90% preservation of estimated glomerular filtration rate (eGFR)]. Multivariable analysis...
