Clinical information
It is not necessary to look through more than readily available reports from previous urine cytologies.
Evaluation
Mainly look for:
Reactive urothelial changes, Pap stain, showing urothelial cells with enlarged nuclei but a nucleus-cytoplasm ratio of less than 0.5. There are bacteria, as well as an inflammatory response of neutrophils, providing a cause for the changes. Can be reported as "Benign urothelial cells, neutrophils and bacteria".
High-grade urothelial carcinoma. Cytologic diagnosis of high-grade urothelial carcinoma requires > 10 cells with high N/C ratio, irregular chromatin pattern and hyperchromatic nuclei (Pap stain).[1]
