Hypercalciuria.

Flocks (1939) first noted an association between renal stone disease and increased calcium excretion in the urine, but it was not until 1953 that Albright, Henneman, Benedict & Forbes coined the term ‘idiopathic hypercalciuria’ to describe the disorder, suggested that it might be tubular in origin, and drew attention to the hypophosphataemia which frequently accompanies it. A few years later Henneman, Benedict, Forbes & Dudley (1958) showed that idiopathic hypercalciuria was associated with a high absorption of calcium, and subsequently Jackson & Doncaster (1959) suggested that this hyperabsorption was an adaptation to the increased urinary loss of calcium. None of these authors was able to define hypercalciuria precisely. Several attempts were
