Summary The intestinal calcium absorption was measured in a group of stone formers using an external isotope counting technique. Hyperabsorption was found in 82% and was even more prevalent in the recurrent cases. Comparison of absorption with urinary calcium excretion showed greater correlation in a group of recurrent stone formers than in cases of apparently solitary stone formation. The finding of intestinal hyperabsorption of calcium in a high proportion of stone formers may be aetiologically significant in the parenchymal calcium deposition found in these cases.
