Several nephrometry score systems aimed to evaluate surgical and functional outcomes has been proposed and compared. Recently, the SPARE (The Simplified PADUA REnal) score has been proposed, with the aim of providing a simpler and more reproducible system. The aim of the current study was to prospectively validate this novel nephrometry score. METHODS: We prospectively enrolled 79 subjected to robot-assisted partial nephrectomy (RAPN) between 11/2019 and 12/2020 at our tertiary care referral center. We excluded those patients with multiple masses and those that underwent previous renal surgery on the same kidney. These patients were subjected to RAPN for clinically staged T1 and T2 kidney cancer. The renal masses were classified according to the SPARE, RENAL, and PADUA nephrometry score and correlations with intra and post-operative complications and optimal surgical outcomes defined according to the margin, ischemia, and complication (MIC) were assessed. RESULTS: Of 79 patients, 48 were male, median age was 58 (IQR: 50-65), and pre-operative tumor size was 30 mm (22.7-40.5). All RAPN were performed transperitoneally. Median warm ischemia time and estimated blood loss were 12 (9.2-17) and 60 (40-100) respectively. Clavien Dindo Complications >2 were 5 (6.3%). MIC was achieved in 63 of cases (79.7%). Patients were stratified according to the three nephrometry scores and the rates of MIC achievement was stratified accordingly as shown in table 1. In the ROC analysis, the AUC of the SPARE scoring system (0.77; CI 95% 0.65-0.89) was higher compared to those of the PADUA (0.70; 0.58-0.82) and RENAL (0.57; 0.42-0.71) scores. CONCLUSIONS: The SPARE score appears to be a promising and reliable score for the prediction of surgical outcomes of RAPN, showing higher accuracy relative to the traditional PADUA and RENAL scores. The main limitation of the study resides in the low number of patients included, which may have been limited the statistical power and will be overcome as more patients are progressively enrolled.
