As of 5/31/16 all urinary tract specimens will be reported using the Paris system nomenclature.  The Paris system represents the first standardized classification system for the reporting of urinary tract cytology specimens.  The primary goals of the Paris system are to establish reproducible findings, improve communication between pathologists and clinicians, and enhance patient management.  The most significant change involves the diagnostic category of "Negative for Malignancy" which was revised to be "Negative for High-Grade Urothelial Carcinoma".  The change in nomenclature reflects cytology's inherently low level of sensitivity for detecting Low Grade Urothelial Carcinoma, but high sensitivity for detecting High-Grade Urothelial Carcinoma.
