Overview

Urothelial carcinomas have 2 main growth patterns:

Papillary urothelial carcinomas: Have slim finger-like projections that grow from the lining of the renal pelvis or ureter into the cavity.
Flat urothelial carcinomas: Lay flat in the lining of the renal pelvis and ureter. They grow deeper into the layers of the wall of the renal pelvis or ureter rather than into its cavity
