In the general opinion of radiologists and urologists and according to current expressions of opinion in textbooks, cystine calculi are difficult to visualize on roentgenologic examination. In a review of 37 cases of cystinuria reported in Sweden, the author found that the condition in 27 was complicated by the formation of calculi. In 18 of the 27 cases a roentgenologic study had been made prior to operation, and in 15 of these 18 cases available cystine calculi were examined roentgenographically with respect to structure and investigated photometrically for the purpose of studying their roentgen density.
In the 18 cases 13 patients were men and 5 were women. The first symptoms of lithiasis usually appeared between the ages of 20 and 25 years, although the age at onset varied from 1I/2 to 64 years. As a rule, the patient had stone symptoms for four or five years before a diagnosis of
