698 EVALUATION OF NON-NEOPLASTIC RENAL PARENCHYMA IN PARTIAL NEPHRECTOMY SPECIMENS

disease using this model with an 87.8% accuracy. We hypothesize that in this era of incidentalomas, tumor size has lost its predictive ability to differentiate benign vs. malignant lesions. We believe that classification trees are easier to use in the clinical setting when compared with logistic regression models as they mimic the clinician’s thought process. This classification tree will be validated with an external dataset.
