The pathophysiology of stone disorder in older adults, as compared to
their younger counterparts, has not been thoroughly investigated. This
article examines the differences in serum and urine chemistries betwe
en groups that are younger and older than 60 years of age. The princip
al finding is that stone formation occurs at lower urinary supersatura
tions in older patients, suggesting that other unexplored factors are
significant contributors. The authors then review the possible effect
of age on the morbidity of stone disease and the implications of stone
disease for the development and management of osteoporosis.
