本文报告了使用热重定量法分析了100例上尿路结石成分。结果:在100例上尿路结石中含纯草酸钙(包括水合度)7例,草酸钙加磷酸钙55例,草酸钙加尿酸15例,草酸钙加尿酸加磷酸钙、纯磷酸钙、磷酸镁铵加磷酸钙各3例,磷酸镁铵加尿酸加磷酸钙、纯无水尿酸、尿酸盐各2例。在难以定量的成份中,草酸钙加磷酸镁铵5例,其他复杂的混合成分3例。根据尿石在不同温度下发生脱水、脱一氧化碳、二氧化
This paper reports the analysis of 100 cases of upper urinary tract calculi using thermogravimetry. Results: In 100 cases of upper urinary tract calculi containing calcium oxalate (including the degree of hydration) in 7 cases, calcium oxalate and calcium in 55 cases, calcium oxalate and uric acid in 15 cases, calcium oxalate and uric acid plus calcium phosphate, pure calcium phosphate, Magnesium ammonium phosphate plus calcium in 3 cases, magnesium phosphate plus magnesium plus calcium phosphate, pure anhydrous uric acid, urate in 2 cases. In difficult to quantify the ingredients, calcium oxalate plus magnesium ammonium phosphate in 5 cases, other complex mixed ingredients in 3 cases. According to uroliths dehydration occurs at different temperatures, carbon monoxide, dioxide
