In this review clinical abnormalities of renal calcium excretion will be examined against the
background of our present understanding of two interrelated areas:(1) the physiology of …

Publisher Summary This chapter discusses the renal handling of calcium. As no evidence
for secretion of calcium by the kidney exists, the renal handling of calcium must be controlled …

Ionized and complexed calcium are filtered at the glomerulus and more than 95% of the
filtered load is reabsorbed along the length of the nephron. In the proximal convoluted …

There have been several comprehensive recent reviews of renal calcium handling,
emphasising either clearance data, micropuncture data, or both (1–4). In this review we will …

METABOLISM of calcium and implications of its derangement in functional and structural
renal alterations offer an imposing challenge. Recent observations by the clinician …

Calcium is reabsorbed in most segments of the mammalian nephron in a pattern generally
similar to that of sodium reabsorption. Of the filtered load, 50%–60% is reabsorbed in the …

To elucidate the relationship between the renal regulation of sodium and calcium excretion
at extremes of sodium intake, we studied 6 normal men ingesting a fixed, 400 mg/day …

T LEAST 90 per cent of all human kidney A stones have calcium as a major crystal
constituent. The investigation of stone pathogenesis most frequently begins with determining …

the importance of calcium in numerous physiological processes, information regarding its
renal excretion and the control of its blood level has been fragmentary and inconclusive …
