RENAL, PADUA NEPHROMETRY SCORES APPLICABILITY FOR RENAL MASSES RESECTABILITY ASSESSMENT

Abstract

The concept of nephrometry scores was introduced in medicine in 2009, and currently there are about 28 scores available. A single evaluated criterion (e.g. C-index, ABC, MAP, etc.) or a combination of criteria (RENAL, PADUA, NePhRO, ROADS, etc.) can be distinguished in each of these systems. The criteria correlate with certain groups of intra- and postoperative complications risk and allow assigning renal masses to potentially resectable or non-resectable ones. The RENAL and PADUA scores have been included to the «staging» paragraph of the Russian clinical guidelines on renal parenchyma cancer since 2021. These scores are based on a set of anatomical characteristics of the masses expressed as points allowing to estimate the index of technical complexity of resection. The structured and standardized assessment employed when planning surgical treatment of renal parenchyma masses makes it possible to reduce greatly the biased estimates by different investigators regardless of a morphological diagnosis. At the preoperative stage, these systems can serve as tools to analyze a potential complexity of resection and to simplify the choice of the surgical intervention volume and technique. This article demonstrates the practical application of RENAL, PADUA nephrometry scores in computed tomography examination by the example of clinical cases.
