Abstract

Le syndrome de levée d’obstacle est une polyurie massive faisant suite au traitement d’une insuffisance rénale obstructive. Les mécanismes physiopathologiques sont multiples : un état de surcharge hydrique qui dépend du caractère complet ou incomplet de l’obstacle, des anomalies tubulaires (atteinte de la capacité de dilutionet de concentration des urines, diminution de la réabsorption dusodium, fuites de potassium, troubles de l’acidification des urines, insensibilité des cellules tubulaires à l’hormone antidiurétique), ainsi que des facteurs biochimiques et immunologiques sont mis en jeu. La levée d’un obstacle nécessite une surveillance clinique et biologique stricte (diurèse horaire, état hémodynamique, état d’hydratation, créatininémie, urémie, ionogramme sanguin). Letraitement a pour but d’éviter les troubles hémodynamiques etmétaboliques graves, et repose sur le principe de la compensation des pertes hydroélectrolytiques.
