The role of RENAL score in predicting complications after robotic partial nephrectomy.

BACKGROUND: The aim of this study is to evaluate the association between tumor complexity based on RENAL nephrometry score and complications. METHODS: We retrospectively identified 2555 patients who underwent RPN for renal cell carcinoma. Major complication was defined as clavien grade≥3. The relationship between baseline demographic, clinical characteristics, perioperative and postoperative outcomes, and tumor complexity were assessed using Chi-square test of independence, Fishers exact and Kruskal Wallis test. An unadjusted and adjusted logistic regression model was used to assess the relationship between major complication and demographic, clinical characteristics, and perioperative outcomes. RESULTS: There was a significant relationship between tumor complexity and WIT(p CONCLUSIONS: Tumor complexity is not associated with an increase in overall or major complication rate after RPN. Experience in high-volume centers is demonstrating a standardization of low complications rates after RPN independent of tumor complexity
