Syndrome polyuropolydipsique

Abstract

Polyuria is defined as a urine flow rate greater than 3 l per day. A water balance disorder (natremia disorder) appears when polyuria and fluid load are not adequately adapted. Major complications can thus occur. Diagnostic approach is essential in order to adapt treatment and consists of determining whether polydipsia is primary and responsible for polyuria or polyuria is primary (diabetes insipidus or solute diuresis) and responsible for polydipsia.
