BACKGROUND: Outcome of @entity1625 ( @entity1625 ) depends on anatomic features of the @entity703 , which can be assessed by nephrometry scores. The aim was to externally validate and refine the Arterial Based Complexity (ABC) score and to compare it to established systems. METHODS: Tumors of 300 @entity1 undergoing @entity1625 were categorized according to the ABC, RENAL, and PADUA score. Size and @entity5 invasiveness were combined to form the @entity52808 score. Correlation analysis and multivariate logistic regression was performed to validate and compare the respective scores as predictors of surgical outcome. RESULTS: The ABC score shows significant correlation with @entity63 time (IT) (P   <   0.01), opening of the collecting system (CS) (P   <   0.01), and conversion to nephrectomy (P   =   0.01). In the multivariate analysis, the ABC score was predictive for on-clamp excision (P   <   0.01) and opening of the CS (P   <   0.01) only. The RENAL and @entity52808 scores were independent predictors for complications (P   =   0.02, P   =   0.05), IT (P   <   0.01, P   =   0.03), on clamp excision (P   <   0.01, P   <   0.01), and opening of the CS (P   <   0.01, P   <   0.01). CONCLUSIONS: The ABC score correlates well with surgical parameters. Expanding the score by @entity5 diameter gives the @entity52808 system. It has similar predictive effectiveness to the well-established RENAL score, but features simplicity by only assessing invasiveness and @entity5 size.

XXXX size and invasiveness matters for @entity1625 : External validation and modification of the arterial based complexity score.
