A Multi-Institutional Matched-Pair Analysis of Robotic Partial Nephrectomy for Single <i>vs</i> Multiple Ipsilateral Renal Masses

Abstract

Introduction: Nephron-sparing surgery is important in patients with multiple renal tumors, especially if associated with a solitary kidney or hereditary syndrome. Prior studies have shown partial nephrectomy (PN) of multiple ipsilateral renal masses to have good oncologic and renal function outcomes. We aim to compare renal function changes, complications, and warm ischemia time (WIT) of partial nephrectomy of a single renal mass (sPN) vs those of partial nephrectomy of multiple ipsilateral renal masses (mPN).
