Study Notes

Hypocalcemia

Hypocalcemia results from decreased 1-alpha-hydroxylation of vitamin D by proximal renal tubule cells and hyperphosphatemia.

Renal Osteodystrophy

Renal osteodystrophy is due to secondary hyperparathyroidism, osteomalacia, and osteoporosis.

Treatment

Treatment involves dialysis or renal transplant.
Cysts often develop in shrunken end-stage kidneys during dialysis, increasing the risk for renal cell carcinoma.
