Reference values for the urinary calcium/creatinine ratio (Ca/Cr ratio) in the first morning urine were established in 361 healthy children aged 5 to 15 years, on unrestricted diets. The urinary Ca/Cr ratio in the urine upon arising was independent of sex but dependent upon age. The measurement of the urinary Ca/Cr ratio in the urine upon arising while

The Lancet, 1975
Urinary calcium and magnesium excretion was measured in two groups of soldiers leaving the temperate climate of the united Kingdom for service in the Persian Gulf. In one group urinary calcium levels and magnesium/calcium ratios were similar, ten days after arrival in the Gulf during the "cold season", to those found in the U.K. The other group went to

Familial Idiopathic Hypercalciuria
New England Journal of Medicine, 1979The frequency of hypercalciuria was determined in the families of nine hypercalciuric patients with idiopathic hypercaliuria who formed recurrent calcium oxalate renal stones. Idiopathic hypercalciuria occurred in 26 of 73 relatives, in three consecutive generations of two families and in two successive generations of four other families.

Pathophysiology of hypercalciuria
American Journal of Physiology-Renal Physiology, 2007worcester et al. ([1][1]) are to be praised for their recent contribution to an understanding of the pathophysiology of hypercalciuria. However, we would like to call their attention to potential pitfalls in their interpretation of three of their data.

Hypercalciuria, defined as the urinary excretion of more than 0.1 mmol Ca/kg/d (4 mg/kg/24 h), is observed in approximately 50% of patients with calcium oxalate/apatite nephrolithiasis and is one of the risk factors for stone formation. Urinary Ca excretion rates among such patients are higher than normal, despite comparable ranges of glomerular ...

Pathophysiology of hypercalciuria
American Journal of Physiology-Renal Physiology, 1984The mechanisms responsible for hypercalciuria may involve intestinal calcium transport, renal tubule calcium reabsorption, and the regulation of bone mineral content. Both parathyroid hormone and 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) may alter urine calcium. For these reasons, understanding the pathogenesis of hypercalciuria in patients has proven to

Hypercalciuria is the most common metabolic abnormality that causes urolithiasis. The pathogenetic mechanisms responsible for hypercalciuria include enhanced gastrointestinal absorption of calcium, increased bone resorption and/or decreased renal reabsorption of calcium; the main dietary factors promoting hypercalciuria are high dietary sodium intake ...

La Revue du praticien, 1998
Hypercalciuria is a very frequent disorder that is defined by a daily calcium excretion rate in excess of 0.1 mmol/kg. Whatever its mechanism, it always expresses an increased input of calcium in extracellular fluid, from intestine and (or) bone. In few instances, hypercalciuria is secondary to an underlying disease that needs to be identified (primary

The frequency of hypercalciuria is increasing in western countries with an incidence of nephrolithiasis which can reach 13%. Hypercalciuria appears as an alteration of the calcium transport system (kidney, bowel, bone) which is regulated by calcitriol and parathormone.

Half of the men and 75 per cent of the women in whom calcium oxalate renal stones form excrete more than 4 mg of urinary calcium per kilogram of body weight daily1 because they have a familial2 normocalcemic form of hypercalciuria. Of the remainder, many others have less severe hypercalciuria that raises their risk of stones.3 High urinary excretion of
