Urothelial carcinoma can arise from any portion of the urothelial lining extending from the kidneys to the urethra, with morphologic subtypes including papillary, polypoid, infiltrative, and ulcerative growth patterns. Imaging plays a crucial role in detecting upper and lower urinary tract tumors and in differentiating them from other benign mimics. Computed tomographic urography (CTU) is the imaging modality of choice for the diagnosis of urothelial carcinoma as well as for noninvasive surveillance following treatment. CTU allows evaluation of recurrent primary tumor while evaluating for metastatic disease in a single study.
