Bladder Cancer Clinic

A characteristic clinical sign of bladder cancer, including in the initial stages, is intermittent hematuria, which can be total, terminal (with localization of the tumor in the neck of the bladder). Hematuria can be significant, leading to severe anemia and sometimes requiring emergency surgical care. Dysuria is caused by both the localization and growth of the tumor, and the addition of infection. Dysuric phenomena in the form of frequent painful urination, imperative urges in the absence of a concomitant inflammatory process are characteristic of cancer in situ. The pain is initially associated with the act of urination, as the tumor grows, the intensity of pain in the perineum and above the womb increases, compression of the ureters and the development of chronic renal failure, pyelonephritis are possible.
