Abstract
LOPEZ DEL VAL, T. et al. Acute water intoxication as a complication of intravenous urography . An. Med. Interna (Madrid) [online]. 2001, vol.18, n.5, pp.45-48. ISSN 0212-7199.
Physiologically, two complememtary mechanisms regulate plasma osmolality: antduretic hormone ADH) and thirst. ADH release s supressed, thirst s inhbted and renal water loss occurs when plasma osmolality belows a threshold level. Yhe rse in plasma osmolalty causes ADH release, stimulation of thirst and water intake. Acute water intoxication is exceptional in patients without a chronic psychiatric disease. Herein, we describe a case of acute water intoxication in a prevously healthy patient, after makng an intravenous urography. The excessive water intake and the impossibility of renal water loss because of streee-induced ADH release originated t. Only nine cases have been previously described; almost they all were women preparing for diagnostic procedures
