Urothelial cells are specialized cells that cover the inside surface of the bladder, ureters, and urethra. In these organs, they connect to form a barrier called the urothelium. These cells are also called transitional cells.
Is it normal for these cells to be found in urine?
Yes, it is normal for urothelial cells to be found in urine. This can be seen when a urine sample is examined under the microscope.
What does it mean if these cells are described as atypical?
Pathologists use the word atypical to describe cells that look abnormal when examined under the microscope. Cells can be described as atypical based on their shape, size, or colour. Atypical urothelial cells can be seen in cancer but can also be seen in other conditions such as infections of the bladder.
What types of cancers start from urothelial cells?
Types of cancer that start from urothelial cells include urothelial carcinoma, papillary urothelial carcinoma, and urothelial carcinoma in situ.
