甘肃疏勒河流域泌尿系结石形成与健康饮食的关系研究

Relationship between constituents of urethral food and healthy calculi in Shule river basin in Gansu province

目的 探讨疏勒河流域泌尿系结石的形成与当地饮食、生活习惯及地理气候的关系,为临床防治提供帮助.方法 对104例泌尿系结石标本的成分进行分析,并结合临床资料与当地饮食、生活习惯及地理气候进行分析.结果 泌尿系结石男性发病多于女性,男女比为4.2∶1,20~50岁多为高危年龄,上尿路结石明显多于下尿路结石,上下尿路结石之比为8.45∶1,结石成分以单纯结石占多数,为94例（90.38%）,其中以草酸钙占75%,磷酸钙结石占7.69%,尿酸结石3.85%,混合结石占9.61%.结论 疏勒河流域结石的成分以草酸钙为主,尿酸结石次之,结石的形成与当地的饮食习惯、地理气候饮水有关,对预防和干预该流域泌尿系结石的形成和复发具有重要的指导意义.

Objective To evaluate the relationship between healthy food and drink and constituents of urethral calculi in Shule River basin, and to provide evidence for the prevention and treatment of urinary calculi. Methods The chemical constitutes of 104 urinary stone samples were detected. The clinical data were analyzed combined with the local dietary habits, geographical and climatic features. Results Urinary calculi were more often found in males than in females and the ratio was 4.2 .＂ 1. Stones occurred more often in the upper urinary system than in the lower urinary system, and the ratio was 6.43 -＂ 1. The most common component of urinary stones were pure stones （90.38%）, which were mainly composed of calcium oxalate （75%）, phosphate stones （7.69%） and uric acid stones （3.85 %）. Conclusions The most common component of urinary stones are pure stones in Shule River basin. The rate of uric acid stones is 3.85%. Healthy diet and geographical features of a place are relevant to the constituents of urethral calculi in Shule River basin. Chemical composition analysis may provide important information for the etiol- ogy and prevention of urethral calculi.
