Hepatorenal syndrome without avid sodium retention
Francis J. Dudley, Gary C. Kanel, Laurence J. Wood, Telfer B. Reynolds – 1 March 1986 – A urinary sodium concentration [U(Na)] of <10 mmoles per liter is considered important in differentiating hepatorenal syndrome from other causes of progressive renal impairment in patients with liver disease. However, occasionally, patients with hepatorenal syndrome have been recognized in whom the U(Na) is consistently >10 mmoles per liter. Eight such patients, in all of whom there was no clinical or laboratory evidence to implicate other causes of progressive renal impairment, were identified.
