Urine cytology is still considered the gold standard when it comes to detection of high grade urothelial carcinoma. While associated with a low sensitivity overall for urothelial abnormality, mostly due to a lack of definitive criteria for identifying low grade lesions, it exhibits excellent specificity with few false-positive cases. Not only does it provide the ability to detect upper tract occurrences, it has a long established use in monitoring those with bladder cancer who’s disease has become more aggressive. Urine cytology still remains a cost effective test for routine screening and detection of urothelial atypia and high grade urothelial carcinoma, and combined with the addition of FISH testing for specific genetic markers urine cytology remains an effective tool in the arsenal of bladder cancer detection and monitoring.
