title: Age-related changes of elements in human ureter.
abstract: To elucidate changes of the ureter with aging, the authors investigated age-related changes of element contents in human ureters. The subjects consisted of seven men and seven women, ranging in age from 61 to 97 yr. The contents of calcium, sulfur, and iron in the ureters increased progressively with aging, whereas the contents of phosphorus and magnesium did not increase with aging. Significant relationships were found both between calcium and sulfur contents and between calcium and iron contents in the ureters, but not between calcium and either phosphorus or magnesium contents. It was noteworthy that a significant relationship was also found between sulfur and iron contents in the ureters. It remains uncertain whether calcium forms a compound with sulfur or iron in aged human ureters or not.
