X-선 회절법에 의한 요로결석 분석

Abstract

Accurate analysis of urinary calculi is fundamental for study of the etiology of stone formation and essential for medical treatment of urinary stone and its prevention of recurrence. Among the various method of stone analysis, we used x-ray diffraction method that is almost absolute identification of crystalline. The following results were obtained. In this study, 5 crystalline components of 30 urinary calculi were demonstrate: calcium oxalate monohydrate, calcium oxalate dihydrate, calcium oxalate trihydrate, uric acid and magnesium ammonium phosphate. Mixed calculus (56.6%) is slight more than single calculus (43.3%). Calcium oxalate monohydrate was the most common pure calculi, composing 9(69.2%) of all pure calculi and mixed calcium oxalate monohydrate+calcium oxalate dihydrate was the most common mixed calculi consisting 10 (58.8%) of all mixed calculi. The most common type of calculi is calcium oxalate monohydrate+calcium oxalate dihydrate (33.3%). Among the all urinary components analyzed in this studies, calcium oxalate monohydrate was the most common constituent, composing 86.6% of the total and calcium oxalate dihydrate was the second common constituent, composing 56.6%
