title: [Combined diagnosis of kidney tumors].
abstract: A total of 127 patients were examined to determine the efficacy of the use of sonography, angionephroscintigraphy and roentgenocontrast angiography in renal tumors and the importance of these methods in diagnostic studies with suspicion for a renal tumor. All the patients were given ultrasound and radionuclide examination, 86 roentgenocontrast angiography. The study has shown a high sensitivity of all three methods in the diagnosis of sizable renal lesions though each one has a different diagnostic tendency. In vascularized tumors the combined use of sonography and angionephroscintigraphy practically ensures 100% diagnosis in a patient even at the out-patient stage of examination. The main difficulties occur in the differential diagnosis of hypovascular sizable tumors when the comparison of the results of all three methods makes it possible to establish correct diagnosis. The advantage of sonography is the absence of traumatism, that of angiography a possibility to determine the functional activity of both involved and intact kidneys. Roentgenocontrast angiography plays the leading role in defining the involvement of the renal and cava inferior veins by a tumor thrombus.
