[Late diagnosis of malignant renal tumors. Review and case reports (author's transl)].

In this paper the problem of early diagnosis in hypernephroid carcinoma of the kidney is explained. Hematuria remains inspite of other possible causes suspect for tumor as long as a tumor is certainly excluded. The different methods for diagnostic and characteristic signs for tumor in the X-ray (EVP) are discussed. Three cases of late diagnosis of hypernephroid carcinoma of the kidney, due to long time not explained symptoms, are described.
