Abstract :

Background: The Paris system (TPS) for reporting urinary cytology is an exercise by experts in the field of urinary system pathology to streamline reporting of urine cytology smears on the lines of cervical cytology reporting system. The primary aim of our study was to find out cases of high-grade urothelial carcinoma (HGUC) using TPS in a general population. Materials and methods: A retrospective study was done to classify as per TPS, all urine cytology smears prepared for various cases of suspected malignancy in the period between 01 Jan 2017 to 31 Mar 2019 at a tertiary care centre in India. All slide smears were reviewed by two experienced pathologists and reclassiﬁed into various categories as speciﬁed by TPS. Histopathology/biopsy reports, where available, were corroborated for correlation with final cytology reports. Results: A total of 661 Geimsa and PAP stained urine cytology smears from 121 patients (91 males and 30 females) were studied. A total of 11 cases were categorized as Category I, 88 as Category II, 03 as Category III, 09 as Category IV ,06 in category V and 04 as Category VI. There were no cases in category VII. Conclusion: Consolidating on previous data from our published study the authors further highlight that TPS is an effective and objective tool for reporting urine cytology specimens and is recommended for early detection of HGUC cases. The detection rate of low-grade urothelial carcinoma (LGUC) by this system is low, in keeping with ﬁndings of other studies on this subject.
