Urine cytology, with cystoscopic examination, remains the standard of practice in the initial evaluation of lower urinary tract lesions to rule out bladder cancer. However, cystoscopy is invasive and may miss some flat lesions, whereas cytology is not very useful in the detection of low-grade papillary neoplasms. Thus, The Paris System for Reporting Urinary Cytology has been developed by members of the American Society of Cytopathology and the International Academy of Cytology to standardize the reporting of urine cytology cases with the goal of improving the detection of high grade urothelial carcinoma. Morphologic criteria for the diagnosis of urothelial carcinoma and intermediate categories of atypia have been better defined. The criteria for each of the categories are based on the best available clinical outcomes evidence. The webinar will address the morphologic features of the different diagnostic categories using case based examples and will identify the potential pitfalls.
