Abstract：Objective: To explore the clinical application value of R.E.N.A.L. nephrometry score based on CT for renal neoplasms in patients undergoing nephron sparing surgery(NSS). Methods: 126 cases with renal neoplasms undergoing NSS in our hospital from January 2009 to March 2012 were selected and their medical records were retrospectively analysed. All patients received plain and enhanced CT scan. The anatomical characteristics of the tumor were graded by R.E.N.A.L. score system. The general conditions, perioperative variables and complications, operation approach, postoperative complications as well as R.E.N.A.L. score were compared. Results: The R.E.N.A.L. score was significantly associated with the operation approach, ischemia time, intraoperative blood transfusion, postoperative complications and the pathological stage of the malignant tumor(P=0.002, P=0.016, P=0.003, P=0.002, P=0.000). Conclusions: The R.E.N.A.L. nephrometry score can help to make surgery strategies and predict perioperative complications.
