Abstract
We sought to determine the importance of calcium phosphate deposition in the functional deterioration of damaged or diseased kidneys. Using the remnant-kidney model in rats, we found that dietary phosphate restriction prevented proteinuria, renal calcification, histologie changes, functional deterioration and death in uremia. Histologic examination of the remnant kidney in the nonrestricted animals showed calcium and phosphorus deposits in the cortical tubular cells, basement membranes and interstitium. A similar degree and pattern of calcification have been found in preliminary studies of human end-stage kidneys.
