Introduction: The nuclear matrix protein 22 (NMP22) assay hasbeen shown to have greater sensitivity for the diagnosis and detectionof recurrent urothelial carcinoma of the bladder (UCB) overthat of traditional urine cytology. We assessed the use of NMP22to predict which high-risk superficial UCB patients will have recurrence,progression or disease-related death; we compared theseresults to standard urine cytology.Methods: One hundred consecutive patients with high-risk superficialUCB were enrolled. During surveillance, urine was collectedfor cytology and NMP22 testing. Patients were followed f

Background. This paper presents our experience with cytologic examination of urine in diagnosing renal allograft dysfunction. Methods. The study group included 23 patients with renal allograft dysfunction, selected from 56 patients who underwent renal transplantation. Etiologic diagnosis was made according to the clinical picture, histological findings during allograft biopsy, and cytologic examination of urine. Urine sediment was obtained in cytocentrifuge and was air dried and stained with May Grunwald Giemsa. Results. Out of 23 patients with allograft dysfunction in 18 (78.3%) patient it wa

Urine evaluation is one of the oldest tests used in ancient medicine. Cytologic examination of urine is a simple, non-invasive, cost effective, and reliable method to uncover a wide variety of reactive and neoplastic processes in urothelium. Urinary tract lesions are often multifocal, may be inapparent on cystoscopic examination or inaccessible to directly biopsy. Thus, urine cytology remains one of the most common methods for the initial diagnosis of urothelial carcinoma that may be manageable with early detection. In this article we review indications for urine cytology, sampling techniques,

463 Background: Urine cytology has often been reported as a highly specific but poorly sensitive test. Cytology is reported as positive, negative, atypical, or suspicious. Atypical/suspicious cytologies account for roughly a quarter of the results and present a clinical dilemma. Physicians’ risk aversion means they are typically treated as positive and result in clinical action. We test the effects of this assumption on sensitivity and specificity.

The main purpose of urine cytology is to detect high-grade urothelial carcinoma (HGUC). With this principle in mind, The Paris System (TPS) Working Group, composed of cytopathologists, surgical pathologists, and urologists, has proposed and published a standardized reporting system that includes specific diagnostic categories and cytomorphologic criteria for the reliable diagnosis of HGUC. This paper outlines the essential elements of TPS and the process that led to the formation and rationale of the reporting system.

Abstract Introduction/Objective The major limitation of urine cytology is the lack of consensus regarding the terminology and diagnostic criteria that should be used for urothelial atypia. The main goal of the newly proposed Paris System for Reporting Urine Cytology is to concentrate primarily on the detection of high grade urothelial carcinoma while minimizing the detection of low grade lesions. This study aimed to apply the criteria and categories of the Paris system in retrospectively collected urine cytology specimens and assess histologic correlation and reproducibility.

The accuracy of multiple voided urine cytology justifies its continued use as a first line diagnostic and detection technique, particularly for high grade invasive cancers and clinically unsuspected case of carcinoma particularly carcinoma in-situ. In this study 57 cases were taken to see correlation of cytology, histology, stage, morphological pattern and sensitivity and specificity of urothelial cancers.

The follow-up of superficial bladder cancer, after TUR and endovesical administration of BCG or other drugs, involves many methods: we studied two groups of patients who underwent TUR for superficial bladder cancer. A group of 54 patients underwent cystoscopy, urine cytologic examination and cytometry; a second group of 30 patients underwent mapping too. The results of the three examinations were compared: high ploidy values were related both with recurrence and progression. The results of cytology plus cytometry were predictive of mapping results and bladder biopsies were useless in up to 50%

An unusual presentation of colorectal metastasis to the upper urinary tract is reported. The metastasis manifested as a filling defect seen during antegrade pyelography. Cytologic evaluation of aspirated material demonstrated metastatic colonic adenocarcinoma. A dilated collecting system may be caused by intraluminal material including tumor and blood clots. Whenever fixed filling defects are encountered, urine cytology should be sent even in the absence of renal parenchymal involvement by tumor. The cytological evaluation may allow for prompt diagnosis and treatment.

Introduction: Urine cytology has been a non-invasive method of choice for detecting urothelial carcinomas but it has several drawbacks including low sensitivity for low grade urothelial lesions, morphology being easily affected by infection, instrumentation, surgery, chemo or immune therapy. Additional screening tests with high sensitivity and specificity for urothelial tumours of all grades are indicated to help improve the diagnostic ability of urine cytology as well as to reduce the need for frequent cystoscopies, especially in those with low-risk disease. Objective: We studied the role of

e16024 Background: The early diagnosis of urothelial cancer allows for effective local treatment and optimizes the success of surgical therapy. Urine nuclear matrix protein 22 (NMP22) was introduced for the detection of transitional cell carcinoma. Add to old NMP22 (ELISA), new NMP22 (immunochromotography method : BladderChek) can be available from 2004. The objective of this study is to determine whether there are any correlation between urine NMP22 (two methods) and the grade or stage of urothelial cancer, and whether it can serve as a biochemical marker of urothelial cancer.

<strong>Background: </strong>Urine cytology is a standard diagnostic test to aid in diagnosis of bladder cancer. It detects the exfoliated cells from urinary tract and helps identify the presence of malignancy. The prognostic value of conventional cytology to monitor patients with superficial bladder carcinoma is well established. The study aims to correlate urine cytology with histopathology of the bladder transitional cell carcinoma and to study the role of urinary cytology in its diagnosis. <strong>Methods: </strong>70 Patients admitted in Department of Urology, SCB Medical C

Exfoliative urinary cytology was performed on 260 new cases of histologically proven urothelial cancer. 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. Malignant cells were found most often when the urothelial tumours were large, papillary and solid, moderately or poorly differentiated and invasive (T2–4). Most upper tract tumours and those situated in bladder diverticula had positive urinary cytology. This study conf

BACKGROUND Urine cytology when combined with cystoscopy remains a gold standard in screening and surveillance of urothelial carcinoma. Paris system for reporting urine cytology (PSRUC) gives seven well defined diagnostic criteria. We aimed to analyse utility of urine cytology in patients with urogenital symptoms, compare existing institutional system (EIS) with PSRUC and assess the performance of both reporting systems in predicting subsequent high-grade urothelial carcinoma on histopathology.

Urine cytology is used for screening of exfoliated bladder cells from voided urine but lacks sensitivity. This study aims to check the efficacy of 5-aminolevulinic acid (5- ALA) fluorescence cytology and establish a high sensitivity approach in detecting flat, in-situ and/or small lesions that are hardly visible under conventional cystoscopy. Intracellular PPIX allows red fluorescence detection. In this study, 5-ALA fluorescent cytology using urine was compared with conventional cytology in the diagnosis of bladder tumors. In this prospective study, we compared the sensitivity and specificity

Abstract Introduction: Urine cytology in bladder tumors is challenging due to the lack of definite cytomorphological criteria in categorizing atypical cases. The study aims to re-evaluate atypia in the light of three definitive cytological parameters (high N/C ratio, hyperchromasia, and irregular nuclear contours) and correlate with the follow-up histopathology and cytopathology with an attempt to redefine the morphological features that would aid in distinguishing reactive atypia from malignancy.
