The Paris System aims to create consistent guidelines for reporting urinary tract cytology results. This study evaluated how well these guidelines work and compared them to the outcomes of follow-up biopsies. A total 70 patient were included in this study out of which 80% were male. Most common age of presentation of urinary bladder lesions was between 61–80 years (55.7%).Most common lesion by urinary cyto-diagnosis according to TPS was found to be HGUC 30 (42.9%) followed by NHGUC 15 (21.4%). The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of the Paris system for urine cytology in assessing urinary bladder neoplasm was 79%,70.9%,83.3%,65.4% ,74.3% respectively. TPS standardizes urine cytology criteria, boosting accuracy and reducing equivocal diagnoses (like atypical urothelial cells). This facilitates high-grade urothelial carcinoma (HGUC) detection.
