UF-100全自动尿沉渣分析仪测定不同时段尿沉渣

目的　探讨同一患者不同时段尿沉渣分析变化及其临床意义。方法　用流式ＵＦ １００ 全自动尿沉渣分析仪测定８７ 例在本院住院的经尿干化学法测定尿红细胞、尿白细胞及尿蛋白阳性病人和２５ 例对照组健康人尿液三个时段，即晨尿、随意尿和餐后尿作尿沉渣定量分析。结果　尿红细胞、尿白细胞浓度依大小分别为晨尿＞ 餐后尿＞ 随意尿；尿白细胞各时段间比较均有显著差异（ Ｐ＜ ０ ．０１） 。尿红细胞：晨尿与随意尿、餐后尿与随意尿间均有显著差异（ Ｐ＜ ０ ．０１） 。晨尿和餐后尿尚未发现有显著区别（ Ｐ＞ ０ ．０５） 。结论　同一患者不同时段尿沉渣结果有差异，测定时应采用同一时段尿进行比较以保证结果准确性。

The Urine Sediments in Different Time Determinated by Flowcell UF-100 Automatic Urine Sediment Analyser

Objective To explore the changes of urine sediments analysed in different time in the same patient and their clinical significance.Method With Flowcell UF 100 automatic urine sediment analyzer,we determinated the urine sediments of 87 hospitalized patients in our hospital at morning,postprandial and any time,who were proved to be blood,leukocyte and protein positive patients by urine dry chemicals analysis,and 25 healthy volunteers.Results The concentration of RBC and WBC is the highest in morning urine,but the lowest in any time urine.The concentration of WBC has significant difference among the three kinds of urine( P <0.01),and that of RBC has similar defference between morning urine and any time urine as well as between postprandial urine and anytime urine( P <0.01).But all results show no remarkable difference between morning urine and postprandial urine( P >0.05).Conclusions The analytical results of urine sediments varied in different time in the same patient.Therefore,urine should be taken at the same time to ensure the precision of the results.
