Proteinuria following nephroangiography. II. Influence of contrast medium and catheterization in dogs
Major increases of urinary albumin were common following nephroangiography in dogs using Urografin (diatrizoate) or Isopaque Cerebral (metrizoate) as contrast medium. Neither the catheterization procedure nor the injection of a supposed inert solution resulted in significant albuminuria but following injection of contrast medium albuminuria commenced within a few minutes; normalization occurred within 2 days. Higher doses of contrast medium induced massive albuminuria than lower ones.
