  1. Urinary bladder carcinoma
    1. Signs & symptoms
      1. Hematuria
        1. Hematuria Physiology
          1. Initial hematuria arises from Urethra ( secondary to inflammation)
            1. Total hematuria arises from: Bladder or upper UT
              1. Terminal hematuria arises from: Bladder neck or prostate urethra
              2. Definition
                1. Hematuria is defined as the presence of 5 or more red blood cells (RBCs) per high-power field in 3 of 3 consecutive centrifuged specimens obtained at least 1 week apart.
                2. Localization of hematuria
