Urothelium (or uroepithelium) is an example of transitional epithelium. It is the type of epithelium that lines much of the urinary tract including the renal pelvis, the ureters, the bladder, and parts of the urethra.
In contrast, the epithelial cells seen on the skin are squamous epithelial cells, that is, they are large and flat. Hence, the presence of columnar epithelial cells in the urine indicates the presence of a pathological condition associated with the kidneys or some other part of the urinary tract. However, if squamous cells are seen, then the urine is contaminated. This can occur in many cases.
