【摘要】 本实验证实含钙尿石形成的尿危险因素是24小时尿高pH、钙、尿酸、草酸和低镁、钠/肌酐、渗透压/肌酐。本组测定值不宜计算形成结石的相对概率,宜采用判别分析。判别值为—22.620,正常人符合率为100.00％,病人为80.56％,两者判别能力有极显著性意义。其中钙、尿酸和草酸对尿石形成的贡献率较高,因此,尿石防治的重点应控制这3个因素。此外还讨论了各危险因素的作用机制及用雷达图形象地表示尿石形成的危险因素。更多还原

【Abstract】 This study shows that an increase in the urinary pH, excretion of calcium, oxalate and uric acid, and a decrease in urinary excretion of magnesium, sodium/creatinine and osmolarity/creatinine are the risk factors of calcium stone formation.It is unsuitable to calculate the overall relative probability of forming stones(PSF), but it is suitable to use discriminant analysis. The. diiicriminant score is -22.620. the correct rate of discrimination for normal subjects and stone patients is 100.00 and 80.56% respectively. The discriminant analysis is highly significant. Since the contributive rates of calcium, oxalate and uric acid are higher in stone formation, the prevention of stone formation lies mainly in controling these factors. The radargraphs express imaginally the risk factors in oxalate, phosphate and urate stone patients. The mechanism of eacb risk factor was also discussed.更多还原
