Evaluation of Urine Cytology in Urothelial Carcinoma Patients: A Comparison of CellprepPlus® Liquid-Based Cytology and Conventional Smear.

Background: Urine cytology is an important test in the screening of urothlelial neoplasms. The conventional smear (CS) method of testing urine samples has a low sensitivity, approximately 50% result accuracy for detecting urothelial carcinomas, while liquid-based cytology (LBC) has much improved diagnostic accuracy, sensitivity, and specificity. The aim of this study was to compare the morphologic features and diagnostic efficacy of CellprepPlus® LBC with those of CS for urine cytology.
