[In vitro ultrasound pictures of kidney tumors].
In 5 patients with malignant renal tumours apart from in-vivo-sonogrammes ultrasound pictures of the operatively removed perfused preparations of renal tumours were additionally performed. The nephrosonogramme intracorporally showed the typical ultrasound picture of a tumour with coarsely disseminated echostructure in acoustically homogenous normal renal parenchyma. In the extracorporal sonogramme the tumour imposed as relatively echo-poor zone compared with the normal renal parenchyma with strong echos. The loss of the extracorporal turgor is discussed as cause of the reversion of the intensity of the echo pattern. In 3 other tumour-free renal preparations the acoustic reversion phenomenon of the normal renal parenchyma was confirmed in the extra-corporal renal preparation.
