Abstract
OBJECTIVES:
To determine if a urine sodium concentration could be used to rule out hypoadrenocorticism in hyponatraemic dogs.
MATERIALS AND METHODS:
Medical records were reviewed for hyponatraemic dogs (serum sodium/L) that had recorded urine sodium concentrations. Twenty hyponatraemic dogs were included: 11 diagnosed with classical hypoadrenocorticism and nine with non-adrenal causes of hyponatraemia. A Wilcoxon rank-sum test was used to compare results between groups.
RESULTS:
No dog with hypoadrenocorticism had a urine sodium concentration less than 30 mmol/L. Urine sodium concentration in dogs with hypoadrenocorticism was significantly higher (median 103 mmol/L, range: 41 to 225) than in dogs with …
