[Diuretic evaluation of bumetanide (author's transl)].

The intravenous administration of 2 mg bumetanide produces a sudden rise in diuresis in a state of hydropenia as well as in a state of previous aqueous diuresis. This rise, which is not accompanied by changes in the glomerular filtrate and renal plasma flow, seems to be due to a decrease in the reabsorption of chloride and sodium in the Henle's loop and probably to a decrease in the absorption of fluid in the proximal tubule, as is apparently indicated by the fractional excretion of water and sodium and the clearance of phosphorus and uric acid.
