Normal Urothelial Cells—bladder washing: A fragment of basal urothelial cells is surrounded by single umbrella cells. Note the smaller nuclei of the basal cells when compared with the umbrella cells which also feature prominent nucleoli.
3. Benign Urothelial Cells—catheterized urine: A cluster of benign urothelial cells is admixed with a few squamous cells. The urothelial cells exhibit a moderately increased nuclear to cytoplasmic ratio although the nuclei are relatively uniform to slightly irregular in contour. The cells contain a variable chromatin pattern and the cytoplasm is homogeneous (absence of vacuoles). Clusters of benign urothelial cells in catheterized urine specimens should not be mistaken for low or high grade urothelial carcinoma.
Reactive Urothelial Cells—catheterized urine: These superﬁcial reactive urothelial cells show homogeneous cytoplasm and mildly hyperchromatic nuclei. Note the low nuclear to cytoplasmic ratio, acute inﬂammation and bacteria in the background. (600x) 40 2. 18. Reactive Urothelial Cells—bladder washing: Degenerated reactive urothelial cells are seen. These cells exhibit nuclear membrane irregularities and nuclear hyperchromasia.
