WebKey points. Children with suspected or known diabetes insipidus (DI) must always have free access to water. Never restrict fluid intake. Urine output may not reflect hydration status. Close monitoring of electrolytes and fluid balance is required for inpatients with DI. This is particularly critical when children are too young or too unwell to ... WebThe typical patient with SIADH has a plasma osmolality of less than 270 mOsm/kg and a urine osmolality that is higher than the plasma. In contrast, a patient with diabetes insipidus has a plasma osmolality greater than 320 mOsm/kg and a urine osmolality less than 100 mOsm/kg. The ratio of urine to plasma osmolality is normally between 1.0 and 3.0.

WebLaboratory tests should include serum and urine osmolality and electrolytes. Euvolemic patients should also have thyroid and adrenal function tested. Hypo-osmolality in euvolemic patients should cause excretion of a large volume of dilute urine (eg, osmolality < 100 mOsm/kg [< 100 mmol/kg]) and specific gravity < 1.003). WebAug 18, 2024 · A urine osmolality greater than 100 mOsm/kg indicates impaired ability of the kidneys to dilute the urine. This usually is secondary to elevated vasopressin (antidiuretic hormone; ADH) levels, which can be physiologic or non-physiologic.
