These cells have an elongated glandular appearance. The cells have small dot-like nucleoli and abundant cytoplasm that is slightly frayed. Diagnostic classification of urothelial cells in urine cytology specimens using exclusively spectral information The results of the current study demonstrate that spectral information, in the complete absence of morphologic or spatial information, allows discrimination of benign and malignant urothelial cells in routine urine cytology specimens. When evaluating a urinary cytology specimen, one of the first aspects that need to be established is the means by which the specimen was collected: clean catch/voided vs. brushing/washing. In voided urines, transitional cells are shed singly; in washings/brushings, the cells tend to be aggregated in sheets and clusters (image A) & (image B); The urothelium is a unique, highly specialized epithelium lining the lower urinary tract.

It is the second most common type of kidney cancer, but accounts for only five to 10 percent of all primary renal malignant tumors. Transitional cell carcinomas arise from the transitional epithelium, a tissue lining Human Urothelial Cells (HUC) Catalog #4320 Cell Specification Urothelial cells, the cells lining the surface of the urinary bladder, are comprised of a unique cell type with high plasticity and a variety of cell functions. They are the first line of bladder defense and serve as an interface between pathogens. Depends: Urothelial cells are normal, blood is not. See urologist for evaluation. Silent Hematuria is a warning sign. Se hela listan på medical-dictionary.thefreedictionary.com 2014-01-02 · Cytoplasmic vacuolation of urothelial cells is regarded as a nonspecific lesion that may occur secondary to cell injury by a variety of bladder toxicants or carcinogens.

The urothelial cells are seen in two main clusters, one cluster of which is smaller than the second. Urothelial cells are a specialized type of cell that line the inner surface of the bladder, ureters, and urethra. These cells connect to form a barrier called an epithelium.

Tumour infiltrating B cells and CD38+ plasma cells have been correlated with survival in different malignancies but their role in urinary bladder cancer is unclear.

The term Urothelial is preferred over Transitional as is is more specific and includes neoplasms with non-transitional differentiation arising in urothelium
Urothelial cancer. Urothelial cancer, also termed transitional cell carcinoma or urinary bladder cancer, is a major cause of morbidity and mortality throughout the world. The highest frequency of cancer in the urinary bladder is found among urban Caucasians in Western Europe and in the United States of America. 2016-10-27
Urothelial cell carcinoma of the urethra (formerly transitional cell carcinoma) is rare and is almost always limited to the proximal urethra in men (membranous and prostatic).

It has a variable number of cell layers, but in the rodent urinary bladder it is usually three cell layers thick in the urinary bladder and more in the ureter. Transitional epithelium is a type of stratified epithelium. This tissue consists of multiple layers of epithelial cells which can contract and expand in order to adapt to the degree of distension needed. Transitional epithelium lines the organs of the urinary system and is known here as urothelium. The bladder for example has a need for great distension. It begins in urothelial cells, which line the inside of the bladder and other parts of the urinary tract.

(MNu) assay is promising for early detection of cancer, such as Shin et al. demonstrated that bladder urothelial basal cells, which are derived from endoderm, are the stem cells for the bladder epithelium. Even though ureteral Bladder cancer starts in the cells of the bladder. A cancerous (malignant) tumour is a group of cancer cells that can grow into nearby tissue and destroy it. Urothelium is a stratified transitional epithelium covering the luminal side of urinary bladder.
2005a). These urothelial cells have enlarged nuclei, with slightly higher N/C ratio and a small nucleolus (26, 27, 28). Some authors have suggested the presence of cells with a nucleolated globular body and variable slender cytoplasm as suggestive of low-grade papillary urothelial carcinoma (35, 36). Transitional cell carcinoma, also called urothelial carcinoma, is a type of cancer that typically occurs in the urinary system. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. It accounts for 95% of bladder cancer cases. It is the second most common type of kidney cancer, but accounts for only five to 10 percent of all primary renal malignant tumors.

The presence of urothelial tissue fragments (UTF) in voided urine (VU) is often considered an abnormal finding that may be associated with the presence of urothelial papillary neoplasms.
