Most physicians and their patients will assume that a positive urine test indicates the presence of a tumor, and will aggressively pursue a diagnosis. The histologic categories were those of the World Health Organization classification system17 and were coded as benign, urothelial papilloma, PUNLMP, LGUCA, HGUCA, and urothelial carcinoma in situ (CIS).
Urine cytology is a microscopic examination of cells found in the urine.
. ... Again the laboratory must be informed of the method of specimen collection for accurate interpretation. In fact, a positive cytologic result in the presence of a negative biopsy result is not always indicative of a false-positive cytologic result. Overall, urine cytology was positive in 135 (52%), suspicious in 28 (11%) and negative in 97 (38%) cases. Background: “Urine cytology, which is widely used to screen for bladder cancer, has high specificity but lacks sensitivity, especially for low-grade cancers,” said Xu. Other areas that can be brushed or scraped include the esophagus (swallowing tube), stomach, bronchi (breathing tubes that lead to the lungs), and mouth. Most of the time, the sample is collected as a clean catch urine sample in your doctor's office or at home.
Exfoliative urinary cytology was performed on 260 new cases of histologically proven urothelial cancer. Of note, when signing out cytologic specimens that are obtained at the same time that a biopsy is performed, the biopsy results are not known by the cytopathologist, mainly for 2 reasons: (1) the fast turnaround time of cytologic cases in comparison with surgical cases and (2) our practice in which cytologic results are provided regardless of the histologic findings (except on very rare occasions).

For the last 14 years at McGill University Health Center, Montreal, Canada, we have used diagnostic terminology for urine cytology that includes an atypical urothelial category, representing a gray zone between the benign category (including reactive and instrumentation changes) and the “suspicious” and malignant categories. Despite the fact that the maximum interval allowed between cytology and histology to calculate the correlation between the 2 was only 1 year in this study, this follow-up time was sufficient to demonstrate the lack of importance of the atypical categories examined. Because of the absence of staining in a wet preparation, these are better limited to examination for crystals and RBCs. RA
Number and date each collection on the containers. On the other hand, a cytologic cut point of greater than atypical, unclear (ie, presence of or suspicion for high-grade carcinoma cells) yields a point far from the line of nondiagnostic results. The site, size, shape and histological grade of the tumours were documented, and they were classified by the TNM system. Overall, urine cytology was positive in 135 (52%), suspicious in 28 (11%) and negative in 97 (38%) cases. The accuracy of urinary cytology for the diagnosis of

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). The “atypical urothelial cell” cytologic category is nonstandardized.
Sensitivity of urine cytology increases with the number of specimens examined. et al. Because of the different atypical categories in our data, we used 3 cytologic thresholds to consider a cytologic diagnosis as positive Table 1: (1) Any atypical diagnosis was considered negative, therefore limiting positive cytology to cases that were categorized as suspicious for or positive for urothelial carcinoma (threshold 1). In a patient with a bladder mass with worrisome imaging or cystoscopy features, the chance of having HGUC is already high (pre-test probability above 50%), even without the knowledge of urine cytology test result. One might correctly assume that the maximum 1-year interval between cytologic and biopsy results that was allowed in this study could have affected the reported cytologic sensitivity and specificity rates.

A small spatula and/or brush is used to remove cells from the cervix (the lower part of the uterus or womb) for a Pap test. Renshaw13 attempted subclassifying the atypical category by using several morphologic criteria that include cellular preservation, cellular clustering, degree of atypia, and extent of atypia. DK

Theoretically, cytology allows sampling of the entire urologic tract, including the upper urinary tract (renal pelvis and ureters), which is not appreciated at the time of cystoscopy. Thanks in advance for any help i can get.
Urine cytology is a highly accurate test for high-grade urothelial carcinoma (UC), with a sensitivity and specificity as high as 79% and 95%, respectively, [1][2][3][4] although this can vary widely. NIH
In our institution, the criteria used to render the majority of the atypical, unclear diagnoses are very similar to the criteria for cells termed by Renshaw13 as pseudodegenerated cells. 2 doctors agree. I did not hear that FISH tests are pretty accurae at detecting high grade. A cytology exam of urine is a test used to detect cancer and other diseases of the urinary tract. Many studies have evaluated the accuracy of urine cytology in the detection of bladder cancer. Urine cytology Perform urine cytology at the same time as cystoscopy, although its routine use for screening is controversial. [Urinary tumor marker for urothelial cancer]. O'Donoghue JM, Horgan PG, Corcoran M, Bredin H, McGuire M, Given HF. The same approach was used in previous studies1 and was thought to be clinically valid for the urologists in our institution. The criteria used to make an atypical, reactive diagnosis are based on some morphologic studies suggesting that cell clusters in voided specimens are associated with higher rates of cancer on histologic follow-up.11,12 However, we restrict this diagnosis to clusters displaying a high N/C ratio (>50%). The FISH Test The FDA approved FISH The diagnostic accuracy of pre-TPS and post-TPS remained similar for all but the AUC category. In contrast, in our study, we used the cytologic diagnoses that had been originally determined, reflecting a real-life situation. The plot demonstrates that cut points in cytologic diagnoses of greater than negative and greater than atypical, reactive yield sensitivities and specificities such that their points fall close to the line of nondiagnostic results. They would assess the morphology of these cells to make a diagnosis. It is a diagnostic test that may be ordered if a doctor suspects that a patient has a cancerous growth in the urinary tract or if a patient appears to have a urinary inflammation or infection.

In comparison, a malignant diagnosis (5.5% of cases) was more often rendered in instrumented specimens (10.3%) or in a surveillance setting (7.7%).
Materials and Methods: Totally, 100 cases including 50 cases each from study group and control group were subjected to post prostatic massage urine cytology and correlated with clinical and histological findings. An ultrasound of kidneys and bladder are negative. Bastacky
A relatively new type of diagnostic technology for bladder cancer are urine tests for substances called tumor markers. Urine cytology is a test for the detection of high-grade bladder cancer. HEMOSUCCUS PANCREATICUS- A SYSTEMATIC APPROACH. Jochims
0. Since the microscopic cellular changes in low grade lesions are minimal these can often be missed. Urine can be examined as a wet preparation or as a dried cytology smear. et al.
Among the 9 patients who had a false-positive result for HGUCA/CIS on cytology, only 4 had a repeated biopsy, and among the 4, 3 were diagnosed with a high-grade lesion within the following year. Urine tests for tumor markers: Newer tests look for certain substances in urine … Urine is formed in the kidneys and, through glomerular filtration, tubular reabsorption and tubular secretion, is how the body gets rid of its natural waste products (Marieb and Hoehn, 2010).
et al. Exfoliative urinary cytology was performed on 260 new cases of histologically proven urothelial cancer. Urine cytology often uses a random urine sample from normal urination to find out if the urine contains tumor cells. Fili
Distribution of Cytologic Diagnoses by Clinical Setting and Type of Specimen*, Cytologic-Histologic Correlation by Diagnostic Categories*, Logistic Regression Analysis of Categories of Urine Cytology vs Two Histologic Outcomes: The Presence of UCA (Low and High Grade) or High-Grade Carcinoma. This threshold appears to be the closest to the urologists’ current approach and daily practice. The main objective of our study was to evaluate the rate and significance of an atypical cytologic diagnosis. 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. Simpanen
Nevertheless, cytologic suspicion for or a diagnosis of high-grade carcinoma was strong related to histologic outcome (P = .005). DC
In clinical practice, the pathologist would manually scan the sample under the microscope to locate atypical and malignant cells. Urinalysis is easy to un… Although urine cytology has rather less sensitivity, its specificity is high. If Blastomyces dermatitidis organisms are subsequently identified by cytology or histopathology, the veterinary clinician is left in a challenging position. The five-year survival rate for individuals with the disease is 77% when compared to the population, however this jumps up to 96% if the tumour has not spread beyond the lining of the bladder wall.1 The prevalence of the disease alongside the importance of early detection mean it’s essential you speak to your Doctor and get tested as soon as possible if you’re experiencing …
A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes.A urinalysis involves checking the appearance, concentration and content of urine. It’s important to know that cytology tests are not always accurate, and other tests are needed to confirm whether cancer is present. Exclusively urine cytology, liquidbased cytology has been proved to get the better yield to diagnose urothelial carcinoma when compared to conventional methods. Urine testing or urinalysis is a valuable tool to screen an patient and diagnose their health status. But it would probably be akin to comparing a CBC vs. blood cytology. Therefore, the correlation between cytology and histology in this context is extremely biased by the clinical impression. 2014 Jan 15;7(2):774-8. eCollection 2014. JI
Because the atypical urothelial category is poorly defined in the literature, interpretation of the comparative data between studies is very difficult. Complete results are shown in Table 3. Pesonen

Low grade tumors are more likely to generate false negatives as with high grade tumors urine cytology is very sensitive and highly accurate. [Medline] . I'm sure if one searches hard enough on the web, one can find the exact techniques used. The test commonly checks … These findings are further illustrated in the receiver operating characteristic plot in Figure 1. D
The urinary tract lining is constantly renewing itself; as new cells grow, the dead ones are shed and carried out of the body in urine. "Cystoscopy, while more accurate than cytology, is an invasive procedure with added costs and potential complications for the patient," he added.
Indeed, whereas the reactive and HGUCA categories generally cause few interpretation difficulties, the “atypical” category remains a wastebasket that encompasses different processes (eg, cell clusters, poorly preserved cells, quantitatively low number of cytologically atypical cells) and is used variably by individual cytopathologists in different institutions.2 In an attempt to standardize the diagnostic categories for urine cytology, the Papanicolaou Society of Cytopathology recommended in 2004 a diagnostic scheme that included an “atypical urothelial cells” category. Changing the threshold to considering the atypical, unclear category among the positive results significantly increased the sensitivity of cytology for high-grade lesions (sensitivity, 70.3%; P = .0001), albeit with a smaller but still significant decrease in specificity (specificity, 66.6%; P = .015). Urine cytology. Raab
The cytologic classification included the following categories: benign (including reactive urothelial cells and instrumentation effects); atypical, favor reactive; atypical, unclear if reactive or neoplastic; suspicious for urothelial carcinoma; and urothelial carcinoma. Slagel
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). Bretton

An atypical diagnosis did not carry a significant increased risk of urothelial neoplasia compared with the benign category. urinalysis is anywhere near as accurate as cytology. EA
This test may also be performed with bladder washings from the cytoscopy.
How the Test is Performed Most of the time, the sample is collected as a clean catch urine sample in your doctor's office or at home.
Urine cytology is associated with a significant false-negative rate, especially for low-grade carcinoma (10-50% accuracy rate). 2001 Nov;28(12):1933-7.
These numbers, which are somewhat low compared with those reported in the literature, have to be interpreted after taking into account several factors. This is the way it was explained to my from Dr. Smith at Vanderbilt University.

One patient had a history of renal cell carcinoma, and 4 had unknown clinical histories. When more than one cytologic specimen existed in a cytohistologic follow-up and correlation, the worst was used as representative of the group for the cytologic-histologic correlation as long as it was rendered within 1 year of the follow-up biopsy Table 2. On the other hand, the specificity of cytology for low- and high-grade lesions was equal (85%). It involves viewing urine sample under the microscope for the presence of significant amount of different types of cells and in the case of pre-cancer or cancer cells, the test also looks at their characteristics. It's specifically useful in diagnosing different urinary tract cancers or recurrences of such. 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). Although an “atypical unclear” diagnosis carried a higher rate of detection of high-grade cancer on follow-up biopsy in comparison with “atypical reactive” or “negative” diagnoses (26/58 [45%] vs 15/52 [29%] and 16/103 [15.5%], respectively), this difference was not statistically significant.

We subclassify atypical cases to “atypical, favor a reactive process” or “atypical, unclear if reactive or neoplastic.” We evaluated the predictive significance of atypical cases by looking at their histologic follow-up. Fourth, the low sensitivity of urine cytology for low-grade lesions (range, 0%–50%)5,20 and the fact that these slow-growing and rarely invasive tumors, even if missed initially, would subsequently be detected by cystoscopy or biopsy without significant tumor progression make urine cytology mainly an important tool to detect high-grade lesions. Grzybicki
Different Thresholds Used to Consider a Cytologic Result as Positive.
The proportion of patients with an instrumented specimen, the number of urine specimens per patient, and the percentage of patients with consistently adequate specimens tended to be higher for patients with high grade malignant neoplasms detected by urinary cytology compared with patients who had high grade malignant neoplasms missed by urine cytology. This is a simple lab test to check for blood and other substances in a sample of urine. B
Indeed, many studies conducted on urine cytology allude to this fact by considering atypical cases as negative in their analyses.1,9. VR
Despite the fact that the usefulness of urine cytology was described more than 60 years ago by Papanicolaou and Marshall,7 a major limitation of urine cytology, in contrast with the Bethesda System for reporting cervicovaginal cytology, is the lack of consensus regarding the terminology and diagnostic criteria that should be used for urothelial atypia. Purpose: Tests to detect recurrent bladder neoplasms are limited and none is consistently accurate. de Voogt
Finally, several studies have shown that the number of samples increases the sensitivity of urine cytology, especially in the detection of high-grade lesions.3–6. We also separately measured the performance of cytology in the following: (1) surveillance of patients with a history of urothelial cancer in comparison with primary detection of cancer in patients with urologic symptoms and (2) voided specimens in comparison with instrumented specimens.

The vast majority of studies considered any atypical cytologic diagnosis as negative and reserved the term positive for cases that were positive for urothelial carcinoma or suspicious for urothelial carcinoma.

An atypical diagnosis was more commonly used in voided specimens (25.9%) or in a surveillance setting (26.5%) than in instrumented specimens (15.0%) or in the evaluation of patients for genitourinary symptoms (18.7%). Although nucleated cells may be seen, in most cases they cannot be identified and are better examined using a dried cytology smear. -, J Urol. 1984 Apr 1;53(7):1555-65 et al. Curling M, Broome G, Hendry WF. et al. 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. It has various indications that generally fall in 2 principal groups: in the evaluation of patients with genitourinary symptoms, especially hematuria, and as a surveillance tool for patients with a history of bladder cancer. It’s important to know that cytology tests are not always accurate, and other tests are needed to confirm whether cancer is present.
If a cancerous condition is detected, other tests and procedures are usually recommended to diagnose cancers, including bladder cancer, ureteral cancer and cancer of the urethra. Third, the relatively low specificity in our study comes from the fact that sensitivity and specificity were calculated based on the number of cytologic-histologic follow-ups and correlations (or biopsies) rather than the number of patients. H
Sensitivity of urine cytology increases with the number of specimens examined. DM
This test is designed to go along with other procedures and tests in order to screen and diagnose any possible urinary tract cancers. The objective was to assess the diagnostic test accuracy of high-risk human papillomavirus (hrHPV) testing of self-collected urine and cervicovaginal samples for the detection of cervical intraepithelial neoplasia grade 2 or higher (CIN2+). The longer the interval between cytology and histology, the more discrepancies between the 2 results one would expect to see because the initial cytologic result might not be reflective of the urothelial tract pathologic state at time of biopsy.
This is one of many tools used to diagnose cancers in the urinary tract, including bladder, kidney, prostate, ureter and urethra cancers. 3 It is possible for these tests to detect substances in the urine that may be linked to the presence of bladder cancer cells, but like urine cytology test, they are not perfectly reliable. T
The vast majority of cytologic-histologic follow-ups and correlations (263/282 [93.3%]) were found to be confined to a period that was less than 6 months between the worst cytologic diagnosis and the subsequent biopsy finding; in fact, the mean intervening time between cytologic and histologic diagnoses was 51 days.

All slides were stained with the Papanicolaou stain. et al. Many studies have evaluated the accuracy of urine cytology in the detection of bladder cancer.
The best-known cytology test that samples cells this way is the Pap test. While the majority of positive cases that were called atypical, unclear on cytology turned out to be high-grade lesions (HGUCA and CIS) on biopsy (57% [26/46] high and 43% [20/46] low grade), the majority of positive cases in the atypical, reactive category were low-grade lesions (ie, 63% [25/40] low-grade vs 38% [15/40] high-grade lesions) Table 4.

The atypia rate in the literature ranges from 1.9% to 20.1%.2,10,21 In comparison, the atypical category constituted 23.2% of all cases in our series. . The two most common urine-based tests are voided urine cytology and UroVysion™ (Vysis, Downers Grove, IL) fluorescence in situ hybridization (FISH) assay. As expected, low-grade lesions were often missed on urine cytology, in contrast with high-grade lesions (sensitivity values of 8.1% and 46.3%, respectively). potential for these urine-based markers to support or replace cytology or cystoscopy has yet to be determined. An accurate measurement of the significance of an atypical in comparison with a negative urine cytologic diagnosis would be possible in only 2 settings: having a histologic follow-up for all urine cytologic specimens, which is an unrealistic and scientifically unfounded approach, or having a long follow-up period without evidence of bladder cancer (ideally, >3 years) in the study population.

A similar approach has been used by others.1,2,5,10. In 10.4% of cases no clinical history was provided. Overall, the reported sensitivity ranges from 20% to 97.3%; specificity ranges from 74% to 99.5%.1,9,16,18,19 In comparison, the ranges of sensitivity and specificity in our study were 29.6% to 69.0% and 49.2% to 85.0%, respectively, depending on which threshold was used to consider a cytologic result positive. Urine cytology tests (the kind that "found" abnormal cells in your sample) are very useful, but must be interpreted with caution.
A cytology exam of urine is a test used to detect cancer and other diseases of the urinary tract. Cytology also struggles to detect early-stage bladder cancer because cancer cells don't show up in the urine in high quantities early on. "Therefore, an inexpensive, non-invasive test for the detection and monitoring of bladder cancer is an unmet clinical need."

URINE CYTOLOGY DEFINITION Urine cytology is a test that involves looking through your urine for abnormal tests. In a nutshell, the atypical, favor reactive category was meant to convey a low probability of malignancy for which only conservative follow-up was intended, whereas the atypical, unclear category was more conceptually akin to the “ASC, cannot rule out high-grade lesion (ASC-H)” and was meant to alert clinicians to take a more aggressive investigative stance. Based on the retrieved list of patients, we then searched for all the subsequent cytologic and surgical specimen reports available up to June 2008 to ensure a minimum of 2 years’ follow-up.

et al. In general, the specificity was lower for low- and high-grade lesions in voided specimens or in a follow-up setting, and this was true regardless of the considered threshold of a positive cytologic diagnosis. A urine cytology test alone can't diagnose cancer. 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.
Finally, in this type of cytohistologic correlative studies, the interval between cytology and subsequent biopsy has a major confounding role in determining the accuracy of cytology.
