Paris system for reporting urinary cytology
Monday 30 May 2016
| PO |
Definition : The Paris System Working Group, organized at the 2013 International Congress of Cytology, conceived a standardized platform on which to base cytologic interpretation of urine samples.
For urologists, understanding the diagnostic criteria, their clinical implications, and the limitations of TPS is essential if they are to utilize urine cytology and noninvasive ancillary tests in a thoughtful and practical manner.
Categories
The recently proposed Paris System for Reporting Urinary Cytology advocates a classification to improve the sensitivity and specificity for the diagnosis of HGUC.
This system utilizes seven categories designated:
(1) inadequate/less than optimal adequacy;
(2) negative for high-grade urothelial carcinoma (NHGUC);
(3) atypical urothelial cells (AUCs);
(4) low-grade urothelial neoplasm (LGUN);
(5) suspicious for high-grade urothelial carcinoma (SHGUC);
(6) HGUC;
(7) other malignancies primary and metastatic.
Each of these categories is well defined by specific criteria and is associated with a known risk for malignancy. The Paris System for Reporting Urinary Cytology also suggested management options for each diagnostic category.
