Bladder cancer differential diagnosis

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Shanshan Cen, M.D. [2]

Overview

Bladder cancer must be differentiated from renal cancer, renal stones, prostate cancer, and cystitis.

Differential Diagnosis

The most common presentation of bladder cancer is hematuria; however in the advanced cases, the presentation can be bladder mass.

Bladder cancer must be differentiated from other causes of hematuria as in the below table:
