Urography Preparation and Anti‐diuretic Hormone

Abstract

A study was carried out on student volunteers in two centres to examine the effects of climate on the normal state of hydration (urinary osmolality). The response of urinary osmolality to fluid restriction, as practised prior to intravenous urography, and the additional response to anti‐diuretic hormone were also examined. The study failed to show a statistically significant difference between effects of the two climates. However, it was found that antidiuretic hormone significantly increased urinary osmolality when values were low prior to hormone administration.
