However, these scoring systems only incorporate tumor factors and fail to capture patient-specific factors, such as body habitus and prior surgical history. We assessed if combining patient- and tumor-specific factors aids in predicting perioperative outcomes. METHODS: We identified 138 patients participating in an IRB approved perinephric fat study for a robotic-assisted PN between 08/2018 and 03/2020. Demographic data, R.E.N.A.L. and Mayo Adhesive Probability (MAP) scores, peri-operative and oncological outcomes were collected. The 1° outcome was to predict trifecta: warm ischemia time25 min, 1 positive margins, 9 had complications). Continuous R.E.N.A.L. (OR 1.13 (1.09–1.18), p<0.001) and MAP (OR 1.06 (1.02–1.11), p=0.008) scores, and male gender (OR 1.21 (1.02–1.45), p=0.034) were associated with failure to achieve trifecta in univariate analyses. Only R.E.N.A.L. and MAP score remained significant in the multinomial logistic regression. The sum of the R.E.N.A.L. and MAP scores showed an association with trifecta outcomes stronger than either score alone (OR 1.72 (1.41–2.15), p<0.001). CONCLUSIONS: Both tumor and patient's specific factors were independently predictive of perioperative outcomes. Combining R.E.N.A.L. and MAP scores, however, showed a stronger association with outcomes than either score alone. We believe that this combination score is a simple and effective way in assisting treatment selection for patients with renal tumors.
