Abstract

Renal cell carcinoma and upper tract urothelial cancer are increasing in incidence. Rates of local recurrence and complications vary with the treatment modality, but the imaging appearance of recurrence and complications is similar no matter the method of local treatment. The use of contrast-enhanced, multiphase imaging is recommended to best evaluate the treatment bed for recurrence and complications. In this article, we cover the most common current local treatments for these cancers along with the patterns of recurrence and complications.

Keywords: CT; MRI; Renal cell carcinoma; Urothelial cancer.
