摘要/Abstract

摘要： 目的　探讨UF-1000i全自动尿沉渣分析仪测定尿电导率同尿液冰点渗透压参数的相关关系。方法　（1）选取1 064名健康成人尿液标本测定电导率，得出健康人群电导率参考区间；（2）随机选取137例因泌尿系统疾病就诊患者的新鲜尿液标本分为正常和超出正常区间2组，使用UF-1000i全自动尿沉渣分析仪和先进公司3300型微渗透压仪分别测定其电导率和冰点渗透压值，并进行相关性分析。结果　（1）健康人群尿电导率参考区间为5.56～30.29 ms/cm；（2）正常参考区间内电导率与渗透压经相关性分析r＝0.942，回归方程为Y＝34.18X－42.29；超出正常区间的电导率与渗透压经相关性分析r＝0.979，回归方程为Y＝32.34X＋4.12。结论　在日常工作中应用UF-1000i全自动尿沉渣分析仪检测尿液电导率可以同尿液常规检查同时进行，比测定尿渗透压更加便捷，有利于早期发现肾脏浓缩稀释功能的变化。

Abstract: Objective　To investigate the correlation between urine conductivity and urine freezing-point osmotic pressure determined by UF-1000i urine analyzer. Methods　（1）The conductivity levels of urine samples of 1 064 healthy subjects were determined. The reference range of urine conductivity in healthy subjects was obtained.（2）A total of 137 random samples were determined for the urine conductivity by UF-1000i and classified into normal group and normal reference range exceeding group，and the urine freezing-point osmotic pressure was determined by Model 3300 Micro-Osmometer. The results of correlation were analyzed. Results　（1）The reference range of urine conductivity was 5.56-30.29 ms/cm.（2）The conductivity of normal reference range group was correlated to the osmotic pressure（r＝0.942）. The linear regression equation of osmotic pressure against conductivity was Y＝34.18X－42.29. The conductivity of normal reference range exceeding group was correlated to the osmotic pressure（r＝0.979）.The linear regression equation of osmotic pressure against conductivity was Y＝32.34X＋4.12. Conclusions　It is more convenient to determine the urine conductivity by UF-1000i together with routine urinary examination in daily work than testing the urine osmotic pressure，which is beneficial for estimating renal concentration and dilution function properly.
