R.E.N.A.L. nephrometry score predicts postoperative recurrence of XXXX treated by radical nephrectomy.

@entity1 @entity1358 @entity5 @entity1349
BACKGROUND: We investigated the association between the R.E.N.A.L. nephrometry score (RNS) and the postoperative recurrence of @entity1358 ( @entity1358 ). METHODS: We retrospectively analyzed a database comprising 91 @entity1 with non-small localized @entity1358 (pT1b-T2b) treated by radical nephrectomy at our hospital from January 2002 to March 2010. RNS was scored based on imaging findings at diagnosis. The Cox proportional hazards model was used to predict @entity1349 ( @entity1349 ) and to calculate hazard ratio (HR). RESULTS: The median age at operation was 63  years (range, 30-85 years). Postoperative recurrence occurred in 19 @entity1 (21  %). Median RNS sum was 9 (range, 5-11). High RNS sum (10-12) was significantly associated with @entity1349 (P  =  0.0012). Multivariate analysis revealed that high RNS sum [HR, 9.05; 95  % confidence interval (CI), 2.11-63.9; P  =  0.0019] were significantly associated with @entity1349 . Regarding each component of RNS, only the L component, which referred to @entity5 location relative to the polar line, was associated with @entity1349 (HR, 15.0; 95  % CI, 2.68-396; P  =  0.0006). CONCLUSIONS: RNS was associated with @entity1349 in cases of non-small localized @entity1358 (pT1b-2b), thus supporting its utility as a prognostic factor.
