Sodium-losing nephropathy and nephrocalcinosis after transplantation.
Severe, prolonged sodium-wasting (up to 38% FENa) occurred in a man after he received a cadaveric-donor kidney. Posttransplantation supplementation with large amounts of saline and/or salt tablets was mandatory. Fludrocortisone had no clinically apparent effect. Plasma renin activity and plasma aldosterone concentration were markedly increased. As chronic rejection progressed, the syndrome ameliorated. Renal biopsy showed cellular rejection and nephrocalcinosis.
