It's specifically useful in diagnosing different urinary tract cancers or recurrences of such. Urine cytology is a test to screen a patient’s urine for cancer cells. Clipboard, Search History, and several other advanced features are temporarily unavailable. Kapur
Therefore, it seems that dividing the atypical category into 2 categories based on the level of cytologic suspicion for cancer does not add clinically significant information within the atypical category. The cytologic-histologic follow-up and correlations were classified as concordance (when the cytologic and histologic results were negative or positive) or as discordance (when one of the two results was positive and the other negative). The site, size, shape and histological grade of the tumours were documented, and they were classified by the TNM system. It's used with other tests and procedures to diagnose urinary tract cancers, most often bladder cancer.Your doctor might recommend a urine cytology test if you have blood in your urine (hematuria).For people who've been diagnosed with bladder cancer and have undergone treatment, a urine cytology test can help detect a recurrence. However, logistic regression analysis of the histologic outcome of tumor (low or high grade) demonstrated that in a multivariate model, neither an atypical, reactive nor an atypical, unclear diagnosis was significantly related to presence of urothelial neoplasm on follow-up biopsy.

If a test is run on a urine sample, first-catch testing (a sample collected from the initial urine stream) is more accurate than clean-catch testing (a urine sample collected midstream). Urine cytology Perform urine cytology at the same time as cystoscopy, although its routine use for screening is controversial. A new urine test could help diagnose aggressive prostate cancer and determine if men with the disease need treatment sooner rather than later.. The study included the data for 199 patients corresponding to 282 cytologic-histologic follow-ups and correlations (608 cytologic and 282 biopsy specimens) were included. Raab
Despite the efforts by cytopathologists in substratifying the atypical urothelial category, the clinicians and urologists at our institution often do not react differently to this subclassification, usually considering the atypical category equivalent to a negative result as long as the cystoscopy and upper tract imaging results are normal. A small percentage of cases had miscellaneous symptoms stated in the requisition (bladder tumor, 3; abdominal pain, 74; cystocele, 1; urine eosinophils evaluation, 1; kidney mass, 2; lymphoma, 1; renal transplantation, 39; ureteral tumor, 3; urethral stricture, 13; vesicoureteral stenosis, 1; abdominal mass, 1; and hereditary nonpolyposis colorectal cancer, 1).

In fact, a positive cytologic result in the presence of a negative biopsy result is not always indicative of a false-positive cytologic result. It is interesting that when the atypical urine cytologic result was considered negative, the sensitivity and specificity of cytology for high-grade lesions in the study by Raab et al2 were comparable to our results with slightly lower sensitivity rates in the present study, probably owing to the high number of low-grade lesions in our cohort of patients (sensitivity values for voided and instrumented specimens of 49.2% and 65%, respectively, in the study by Raab et al2 compared with 44.2% and 51% in our study, and specificity of 89% and 85.7% in the study by Raab et al2 compared to 82% and 90% in our study, respectively). diagnostic test accuracy and provides with an estimate of ROM in varios clinical scenarios or settings.
