The complex<unk>  can be further evaluated with doppler ultrasonography, and for Bosniak classification and follow-up of complex<unk> s, either contrast-enhanced ultrasound (CEUS) or contrast CT is used. Histopathology of the lining of a simple<unk>  of the kidney, incidentally found on autopsy, with inconspicuous nuclei. They usually have a single layer of cuboidal, flattened or atrophic epithelium, but this case has a somewhat thicker fibrous layer. H&E stain.
