ABSTRACT
BACKGROUND/AIM:
This study investigated the impact of available preoperative imaging on the reliability and predictive accuracy of RENAL and PADUA nephrometry-scoring systems for renal tumors. PATIENTS ANDMETHODS:
Five urologists determined RENAL and PADUA scores using preoperative imaging data (computed tomography and magnetic resonance imaging) of 100 patients admitted for partial nephrectomy with the following combinations T0 transverse planes without excretory phase (EP), TC0 transverse and coronal planes without EP, TC1 transverse and coronal planes with EP. Reference standard was obtained by a uro-radiologist. Ischemia time was used as surrogate for surgical complexity.RESULTS:
Assignment of EP significantly reduced interobserver-variability among urologists (p<0.0001). Predictive accuracy for surgical complexity or correct assignment to nephrometry risk groups did not depend on image planes or EP.CONCLUSION:
Interobserver variability, but not predictive accuracy of nephrometric systems, is affected by additional usage of EP.Palavras-chave
