Course Description

The Paris System for Reporting Urinary Cytology (TPS) has been developed by members of the American Society of Cytopathology and the International Academy of Cytology to emphasize the goal of detecting High Grade Urothelial Carcinoma (HGUC) while minimizing the emphasis on Low Grade Urothelial Neoplasms(LGUN). Consequently, definition of the characteristics of the intermediate category of atypia aims at decreasing that category into a clinically meaningful one. Criteria for each category have been based on the best available clinical outcomes evidence. Rather than attempt to diagnose urothelial lesions in relationship to surgical pathology terms (WHO/ISUP Classification), TPS capitalizes on strength of cytomorphology for detecting HGUC because this diagnosis is both most meaningful for the patient and most realistic for the cytologist. The course will be constructed around the categories of TPS instructors will each address their particular category of interest: Adequacy, Olson; Negative for HGUC, Kurtycz; Atypical Urothelial Cells, VandenBussche; Suspicious for HGUC, Barkan; LGUN & HGUC, Wojcik. After this didactic presentation, there will be a question and answer period during which participants will be able to ask questions of the presenters. This course is designed for cytopathologists, pathologists, cytotechnologists, or urologists at any level from trainee to experienced practitioner who deals with urinary cytology samples.

Learning Objectives

Upon completion of this educational activity, the learner will be able to:

  • Elucidate the rationale for standardizing urinary cytology reporting
  • Assign samples into the various diagnostic categories
  • Recognize the morphologic characteristics to assign samples into the groups
  • Appreciate clinical management implications of the diagnostic categories
  • Relate the relative risk of HGUC according to the results of the Cytologic interpretation for each diagnostic group.


Continuing Medical Education and Maintenance of Certification

The United States and Canadian Academy of Pathology is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians.

The United States and Canadian Academy of Pathology designates this live activity for a maximum of 3 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

The USCAP is approved by the American Board of Pathology (ABP) to offer Self-Assessment credits (SAMs) for the purpose of meeting the ABP requirements for Maintenance of Certification (MOC). Physicians must take and pass the post-test in order to claim SAMs credit.

Physicians can earn a maximum of 3 SAM credit hours.
