Abstract
The process by which hypercalcemia reduces renal concentrating ability was investigated by measuring the changes in basal and arginine vasopressin (AVP)-induced osmotic water (Pf) and urea (Purea) permeabilities in isolated perfused inner medullary collecting ducts (IMCDs). Results showed that selective changes in IMCD transport occur in hypercalcemia, allowing the body to excrete excess calcium without forming calcium-containing kidney stones.
