Renal and Absorptive Hypercalciuria: A Metabolic Disturbance With Varying and Interchanging Modes of Expression

Abstract

We suggest that AH and RH constitute a continuum. The change in characteristics observed during the second study suggests that any attempt to divide these patients into two physiologically distinct subtypes may be artificial. The main factor influencing urinary excretion of calcium in our patients seemed to be sodium intake.
