Obstruction urinaire basse : Attention à la levée d'obstacle !

The syndrome of "post-obstructive diuresis" corresponds to a massive polyuria and natriuresis occurring after the drainage of an obstructive acute kidney injury. Such a complication needs to be readily detected and managed because of the significant risk for haemodynamic disorders. On the basis of a clinical observation, we describe the pathophysiology of post-obstructive diuresis, as well as its diagnostic and therapeutic management.
