Urine osmolality distinguishes DI from osmotic diuresis. To improve reliability and comparability we propose the following definition for postoperative DI polyuria (urine production 300ml/hour for 3h) accompanied by a urine specific gravity (USG) 1.005, and at least one of the following symptoms excessive thirst, serum osmolality 300mosmol/kg, or serum sodium 145mmol/L. To prevent unnecessary treatment with desmopressin, we present an algorithm for the diagnosis and treatment of postoperative DI. 145 mmol/L.
