title: [Flow volume-velocity relationship in the circulation of acutely failing kidney transplants (experimental study)].
abstract: The volume velocity-relation of renal blood flow was examined in transplanted dog kidneys during the oliguanuric phase of the acute renal failure (ARF). Under these circumstances it is possible to separate the ARF in consequence of ischemia or hypoxia of the transplant or in consequence of rejection. A significant relation between the total blood flow and the mean flow correlation exists in the acute functional failure of ischemically injured autotransplants as in the case of autochthonous kidneys. This velocity is also kept in the acute insufficiency of autotransplants induced by shock although there exists a stronger redistribution of cortex circulation than after the ischemic insultus. Extreme low or high circulatory velocities without a relation to the blood flow originate from the deficiency of extensive vascular regions and the formation of arteriovenous shunts in acutely failing rejected homotransplants.
