Home | Paris System for Urinary Cytopathology | University of Wisconsin–Madison

Introduction: Urine cytology is an important screening tool of patients for urothelial carcinoma UC and follow-up of patients with treated disease. Ease of procurement, cost-effectiveness, and lower turnaround time are the major advantages. Materials and Methods: One-year retrospective study of 90 cases was undertaken wherein cases presenting with painless hematuria and clinically suspicious of UC were included. Urine cytology slides were reviewed and reported with TPS guidelines. These findings were correlated with histopathological diagnosis and urine culture as indicated.

Lambl in The Paris System for Reporting Urinary Cytology was created in response to perceived problems with diagnostic reproducibility and clinical utility in urinary cytopathology. The Bethesda System for Reporting Cervical Cytology and the Bethesda System for Reporting Thyroid Cytopathology, 4,5 which are predecessors to the Paris System, have shown the value of international bodies of experienced pathologists and clinicians coming together to agree on morphologic criteria, risk assessment, and reasonable clinical objectives. These systems have been maintained and updated through professional societies. The problem of older cytologic systems is that they tended to be individual efforts that existed in static forms within textbooks. As new information became known and new opinions were formed, practitioners tended to add their own interpretations to the information in the texts, and divergence in criteria would occur.

The Paris System for Reporting Urinary Cytology represents a significant improvement in classification of urinary specimens. The system acknowledges the difficulty in cytologically diagnosing low-grade urothelial carcinomas and has developed categories to deal with this issue. The system uses six categories: unsatisfactory, negative for high-grade urothelial carcinoma NHGUC , atypical urothelial cells, suspicious for high-grade urothelial carcinoma, high-grade urothelial carcinoma, other malignancies and a seventh subcategory low-grade urothelial neoplasm. Three hundred and fifty-seven urine specimens were independently reviewed by four cytopathologists unaware of the previous diagnoses. Each cytopathologist rendered a diagnosis according to the Paris System categories. Agreement was assessed using absolute agreement and weighted chance-corrected agreement kappa. Disagreements were classified as low impact and high impact based on the potential impact of a misclassification on clinical management.

INTRODUCTION

The new method is based on the collective experience of knowledgeable cytopathologists who have tested the terminology within their own laboratories for reproducibility and predictability of neoplasms of the urinary tract. Accompanying the written criteria for each diagnostic category are meticulously photographed exemplars of the cellular features, with cogently annotated descriptions of the photographs. Included in the targeted readership are experienced pathologists, cytotechnologists, and students of both professional groups. The new terminology also considers the clinical aspects of patient management. Written by experts in the field who convened at the 18th International Congress of Cytology in Paris, The Paris System for Reporting Urinary Cytology presents a global standard for reporting and a new philosophic approach that maximizes the strengths of detecting the potentially lethal high grade lesions by urinary cytology, and recognizes without apology the inability to reliably detect the low grade lesions in urinary cytology.

Accessed October 10th, Urine Cytology represents a significant portion on non-gynecologic cytology specimens in daily practice, primarily because of the simplicity and ease of specimen procurement and its significant impact on management However there was no consensus on the various categories and their cytomorphologic features used for reporting Paris System for reporting urinary cytology was an effort to standardize terminology with standardized cytomorphologic criteria for reporting urine cytology Paris System is based on the principle that the ultimate goal of urine cytology is detection of high grade urothelial carcinoma.
