[Diagnosis of space-occupying processes of the kidney by sequence scintigraphy and renovasography]

Proof and classification of a space-demanding process of the kidney is most successfully done by means of renovasography. The nuclear-medical investigation methods give only unspecific references to the disease. Investigation results of radionephrography, sequence scintigraphy and renovasography of 130 kidneys with space-demanding processes were comparatively evaluated. Renovasographically the findings of 35 malignant tumours, 58 solitary cysts and 37 polycystic degenerations were correctly classified. The radionephrography is of no importance for the diagnostics of space-demanding processes. The results of the sequence scintigraphy were in demands of space localised defects of parenchyma, reductions of parenchyma and one a non-functioning kidney. These findings gave rise to angiographical clarification. In the polycystic degeneration the irregular distribution of the activity in the parenchyma, multiple parenchymal defects and the enlargement of the organ referred to the disease.
