Low-grade lesions are placed in the category negative for high-grade urothelial carcinoma. Each diagnostic category carries a risk of high-grade malignancy that guides management, and the edition adds a chapter on urine from the upper urinary tract.","asOf":"2026-11-04","links":[{"label":"Wojcik et al., The Paris System for Reporting Urinary Cytology 2022 (J Am Soc Cytopathol 2022)","url":"https://doi.org/10.1016/j.jasc.2021.12.003"}],"tags":[],"related":["vi-rads","who-cytopathology-reporting-systems"],"cancers":["urothelial"],"sections":[],"technologies":["urine-bladder-cancer-tests"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Pathology"},"route":"/terms/paris-system-urinary-cytology/","neighbours":{"term":[{"id":"bethesda-category","kind":"term","name":"Bethesda category (thyroid cytology)","route":"/terms/bethesda-category/"},{"id":"vi-rads","kind":"term","name":"VI-RADS (Vesical Imaging Reporting and Data System)","route":"/terms/vi-rads/"},{"id":"who-cytopathology-reporting-systems","kind":"term","name":"WHO Reporting Systems for cytopathology","route":"/terms/who-cytopathology-reporting-systems/"}],"cancer":[{"id":"urothelial","kind":"cancer","name":"Bladder & urothelial cancer","route":"/cancers/urothelial/"}],"technology":[{"id":"urine-bladder-cancer-tests","kind":"technology","name":"Urine tests for bladder cancer (cytology, FISH, RNA and methylation)","route":"/technologies/urine-bladder-cancer-tests/"}]}}
