Hyponatremia is the main complication of inappropriate antidiuretic hormone secretion (SIADH), sometimes fatal. Treatment strategy depends on the cause and the severity of the hyponatremia. Recent studies have shown the efficacy of urea in treating acute hyponatremia secondary to SIADH, by inducing an osmotic water drive. We describe an infant with chronic hyponatremia secondary to SIADH in which the long-term oral treatment with urea was successful and well tolerated. The aim of this paper is to highlight the potential benefits of urea treatment in case of chronic hyponatremia secondary to SIADH. CONCLUSIONS Chronic oral urea treatment in children with SIADH allows an easy and safe water and sodium control and may permit a decrease in fluid restriction in this situation.

UI	MeSH Term	Description	Entries
D007010	Hyponatremia	Deficiency of sodium in the blood; salt depletion. (Dorland, 27th ed)	Hyponatremias
D007177	Inappropriate ADH Syndrome	A condition of HYPONATREMIA and renal salt loss attributed to overexpansion of BODY FLUIDS resulting from sustained release of ANTIDIURETIC HORMONES which stimulates renal resorption of water. It is characterized by normal KIDNEY function, high urine OSMOLALITY, low serum osmolality, and neurological dysfunction. Etiologies include ADH-producing neoplasms, injuries or diseases involving the HYPOTHALAMUS, the PITUITARY GLAND, and the LUNG. This syndrome can also be drug-induced.
