During the 13 years from July, 1971 to August, 1984, 1896 patients were diagnosed as urolithiasis at our University Hospital. These cases were retrospectively analyzed. The male to female ratio was 2.4 to 1. The peak age incidence of urinary calculi occurred in the third decade. The ratio of upper urinary tract stones to lower urinary tract stones was 18 to 1. As to the laterality of the upper urinary tract stones, the ratio of left to right was 1.3 to 1. Analysis of the stone components revealed that the frequency ob calcium oxalate mixed with calcium phosphate and pure calcium oxalate was 80 percent and struvite, uric acid & cystinine were 14.1%, 2.6%, 1.6% respectively.
