title: Renal cytology.
abstract: FNA of renal tissue is a rapid and noninvasive diagnostic tool that can be optimized by a thorough understanding of renal diseases, anatomy, and the ultrasonographic appearance of lesions likely to exfoliate for cytology. Signalment, history, and ancillary laboratory tests can narrow the list of differential diagnoses and help to determine whether cytologic evaluation will be sufficient or whether tissue architecture is needed for a definitive diagnosis. Renal cytology is particularly useful for the diagnosis of inflammation and neoplasia, including abscesses, FIP, mycotic infections, lymphoma, carcinoma, and metastatic neoplasia.
