Predictive Factorsfor Final Pathologic Ureteral Sections
Predictive Factorsfor Final Pathologic Ureteral Sections
To identify preoperative predictive factors for final ureteral section invasion after radical
 cystotomie (RC) and to validate significant factors on an external independent cohort. The
 investigators retrospectively reviewed data of all consecutive RC performed for bladder
 cancer in 2 high-volume institutions. Clinical, pathological, and follow-up data were
 collected prospectively and reviewed retrospectively. Pathological evaluation was performed
 by 2 well-trained uropathologists in each center. Logistic regression analyses were performed
 to identify predictive factors for final ureteral sections involvement. Significant factors
 in cohort A were validated in cohort B. Receiver operating curve and area under curve were
 modeled to evaluate predictive accuracy of the markers
