[Echographic diagnosis of hypernephroid cancer].

A total of 28 hypernephroid tumours have been diagnosed within a period of 32 months. The data from echographic, intravenous urography, computer tomography and thin-needle aspiration biopsy and renovasography were compared in the patients studied. Two basic variants of echographic picture have been described. It has been concluded that the combination of abdominal ultrasound tomography with thin-needle aspiration biopsy is a valuable method for the diagnostics of hypernephroid cancer. Computer tomography proved to be appropriate in solving the problem of operability, renovasography--pre-operatively, and the rest of the methods--in suspected and undistinguished echographic evaluations.
