Improved diagnostic precision of urine cytology by implementation of The Paris System and the use of cell blocks

Abstract

In support of the new TPS recommendations, the application of stringent "TPS-like" and TPS criteria improves the value of an AUC diagnosis for clinicians and patients by lowering the AUC rate and increasing the positive predictive value of AUC for high-grade urothelial carcinoma. CBs can be used to help resolve problematic cases for more definitive diagnostic categorization.
