Objective Does the simplified PADUA renal (SPARE) nephrometry system predict perioperative outcomes after partial nephrectomy (PN)? Methods This systematic review and meta-analysis were conducted in accordance with the PRISMA statement. A systematic search of the literature published before August 1, 2024, was conducted using PubMed, Embase, Cochrane, and Web of Science libraries. We included all articles patients with SPARE score for PN. Results A total of 1,831 patients from six studies meeting the criteria were included. Higher SPARE scores were significantly associated with several perioperative outcomes after partial nephrectomy and may serve as a practical tool for preoperative tumor complexity assessment and perioperative risk stratification, particularly in the context of robot-assisted partial nephrectomy given the composition of current evidence. Conclusions The SPARE score was significantly associated with several perioperative outcomes after partial nephrectomy and may serve as a practical tool for preoperative tumor complexity assessment and perioperative risk stratification.
