    Abstract:
    Decreased free water excretion and the development of interstitial edema are recognized characteristics of preeclampsia. However, the pathophysiology of decreased urine excretion in preeclampsia is presently controversial: diminished glomerular filtration, renal arteriolar spasm, elevated plasma vasopressin levels, and plasma volume contraction have been suggested as etiologies. We studied seven pregnant patients with a diagnosis of mild preeclampsia to assess the role of vasopressin, serum protein, and glomerular function in the renal excretion of water. The ability to excrete a water load was significantly and directly correlated with serum albumin (P less than 0.05) and protein (P less than 0.02) concentrations. Neither plasma vasopressin nor creatinine clearance correlated with water excretion. The similarity of preeclampsia and the nephrotic syndrome with regard to the renal excretion of water is discussed.
