Urine cytopathology aids in diagnosing urothelial neoplasia but has mimics. This review covers diagnostic challenges and ancillary tests for accurate interpretation.
Area of Science:
- Urology
- Cytopathology
- Oncology
Background:
- Urine cytopathology is a valuable, noninvasive method for diagnosing and monitoring urothelial neoplasia.
- It complements emerging molecular diagnostic techniques.
- Diagnostic interpretation can be challenging due to mimics and pitfalls.
Purpose of the Study:
- To review entities that mimic urothelial neoplasia in urine cytology.
- To discuss diagnostic challenges and pitfalls in urine cytopathology.
- To consider ancillary tests that aid in the diagnostic process.
Main Methods:
- Literature review of urine cytopathology and urothelial neoplasia.
- Analysis of diagnostic mimics and pitfalls.
- Evaluation of ancillary testing in cytopathology.
Main Results:
- Urine cytology is effective but requires careful interpretation.
- Numerous entities can mimic urothelial neoplasia.
- Ancillary tests can improve diagnostic accuracy.
Conclusions:
- Urine cytopathology is essential for urothelial neoplasia management.
- Awareness of mimics and pitfalls is crucial.
- Ancillary tests enhance diagnostic confidence and accuracy.
