ABSTRACT

Introduction: The increase in imaging diagnosis has caused a remarkable rise in the detection of kidney tumors in their first stages. Nephrometry is an original scoring system based on the renal mass images that help select the surgical technique: radical or nephron-sparing surgery and the open or minimally invasive approach as well as the prediction of potential surgical complications. The nephrometric systems are currently the best tool to classify renal masses and they contribute to unify the language between radiologists and urologists. The aim of this article is to comment on the use of RENAL score in the assessment of renal masses, especially in surgical treatment through laparoscopic/robotic approach. Scientific articles related to the topic were consulted from three sources: Scielo, Ebsco and Pubmed.
Analysis of the information: There has been a recent concern to standardize decision-making in the treatment of renal tumors with nephrometric systems, which are structured and quantifiable methods for describing relevant anatomical findings of the tumor. RENAL score analyzes the morphologic characteristics of the tumor: size, depth penetration in the renal parenchyme, relation with the collector system and the hilar vessels, longitudinal and antero-posterior localization; establishes the characteristics of renal masses and guides the selection of the surgical technique and the prediction of postoperative complications, especially in partial or nephron-sparing nephrectomy.
Conclusions: RENAL score, one of the most used nephrometric systems, has its greatest use in predicting postoperative complications and thus in the selection of partial vs radical surgery. It has become an indispensable tool in the indication of partial nephrectomy, in renal tumors, through laparoscopic/robotic approach.
