Sodium Diuresis after Relief of Obstructive Uropathy

Abstract

STRIKING urinary losses of water and sodium after relief of chronic urinary-tract obstruction were first recorded by Wilson, Riseman and Moyer.1 Further cases were reported by Parsons2 and by Bricker et al.3 Many of these patients appeared to lose sodium and water at such a rate that a clinical state of dehydration and shock resulted.
