Urine typically contains epithelial cells shed from the urinary tract, and urine cytology evaluates this urinary sediment for the presence of cancerous cells [2] [3] from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for urinary tract cancers.
Primary urethral cancer is rare and contributes to less than 1% of all cancers. It is three times more common in men than women and its incidence rises after the age of 75. [1] Around half of affected people have locally advanced disease when they first present. 54–65% of cases are of the urothelial carcinoma type. [1]
Bladder cancer is the abnormal growth of cells on the bladder. These cells, which originate in the urothelium, can grow to form a tumor, which eventually spreads, damaging the bladder and other organs. Most people with bladder cancer are diagnosed after noticing blood in their urine.
Facet cells (also known as umbrella cells, [1] capping cells, superficial urotheliocytes) are a type of cells located in the renal pelvis, the ureters, and the urethra. Umbrella cells form the outermost layer of the urothelium , which is a special type of epithelium found in the renal pelvis , the ureters , and the urethra .
Invasive urothelial carcinoma is a type of transitional cell carcinoma. It is a type of cancer that develops in the urinary system: the kidney , urinary bladder , and accessory organs. Transitional cell carcinoma is the most common type of bladder cancer and cancer of the ureter , urethra , renal pelvis , the ureters , the bladder , and parts ...
The tumor is made of a fibrovascular core covered by seemingly normal urothelium tissue. Under microscope, papillary (finger-like) fronds can be seen that feature occasional branching, but no fusion. Genetic Associations
Symptoms of urothelial carcinoma in the bladder include hematuria (blood in the urine). Diagnosis includes urine analysis and imaging of the urinary tract ( cystoscopy ). It accounts for 95% of bladder cancer cases and bladder cancer is in the top 10 most common malignancy disease in the world and is associated with approximately 200,000 deaths ...
