Abstract

In moderate mannitol diuresis in the dog the ratio RBF-86Rb uptake/RBF-electromagnetic flowmeter decreased during ureteral obstruction from 0.923-0.705. In the same animals the ratio RBF-133Xe wash-out/RBF-electromagnetic flowmeter increased from 0.932-1.365. With the rubidium technique a significant redistribution of intrarenal blood flow was observed. No similar flow changes were seen with the133Xe wash-out technique. The two methods do not measure during ureteral obstruction the true RBF. The change of86Rb uptake by the individual segments of renal tissue is not an unequivocal proof for the intrarenal redistribution of bloof flow, but this possibility cannot be definitely excluded.
