Contrast and electrolyte dynamics of the intravenous pyelogram. I. Urinary pH and volume changes in the canine I. V. P.
Canine peripheral venous or suprarenal aortic injections of sodium or meglumine iothalamate produced a significant swing towards an alkaline urine only in individual dogs injected with meglumine salts. When mean values were compared for the sodium or meglumine groups as a whole, however, no significant differences could be established for pH change or induced diuresis. With both salts, ATPase inhibition could play a role in urinary electrolyte excretion. Carbonic anhydrase inhibition does not seem to play a significant role in urinary pH changes induced by contrast media.
