Abstract:
Two hundred thirteen urinary calculi were analyzed by X-ray diffraction method, which were obtained from the patients who were treated at the Department of Urology, Pusan National University Hospital from May 1989 to October 1993. The composition of our stone is classified to eleven. Pure stone was comprised 59.2 percents of all cases, and mixed stone was 40.8 percents of total. Calcium stone was 78.9 percents of all cases and non-calcium stone was 21.1 percents. Comparison with other clinics result using same study, the ratio of uric acid is significantly high. Calcium oxalate was the most common type in pure calculi( 83.3%) and mixed calcium oxalate and calcium phosphate calculi was the most common type in mixed calculi(52.9%) Calcium oxalate stone was the most common among the stones containing calcium, constituting 110(51.6%). Urate stone was the most common in non-calcium stone, constituting 24(11.3%) Ammonium acid urate containing stone was the largest in their size, uric acid stone was the smallest.
