Abstract

Following the amazing acceptance of The Paris System for Reporting Urinary Cytology (TPS), the second edition (TPS 2.0) was inevitable. Based on new studies since the publication of the first edition, diagnostic criteria are refined, and pitfalls discussed. In addition to reinforcing the mandate that the focus of diagnostic urinary cytology is the detection of high-grade urothelial carcinoma, other issues are addressed. Low-grade lesions are included in the category of negative for high-grade urothelial cancer. The rationale for that decision is strongly supported by evidence from the authors’ experiences as well as the recent literature. A new chapter on urine cytology of the upper tract, a rarely addressed topic, explores the challenges involved. Furthermore, the issue of cellular degeneration is discussed in the criteria of all diagnostic categories. Most importantly, data defining the risk of high-grade malignancy (ROHM) for each diagnostic category informs clinical management. The 65 authors are recognized authorities from 33 countries, attesting to the global impact of TPS 2.0.
