清洁中段尿留取方法改进及其临床应用效果评价

To improve the collected method of middle clean urine and appraise the effect of its clinical application

目的改进清洁中段尿的留取方法，提高临床检验准确性。方法将我院门诊内科治疗室从2010年1月至2012年1月466例留取清洁中段尿的患者，随机分为对照组（n=233）和改良组（n=233）；对照组按照传统方法留取清洁中段尿；改良组在清洁中段尿留取方法改良前按照传统方法留取清洁中段尿，在清洁中段尿留取方法改良后应用自制长柄套及镂空式坐椅等辅助用具留取清洁中段尿；统计对照组及改良组清洁中段尿标本污染例数，比较2组的污染率。结果按照传统方法留取清洁中段尿，对比对照组和改良组清洁中段尿的污染率，对照组和改良组之间差异无统计学意义，P〉0．05；清洁中段尿留取方法改良后，对比对照组和改良组清洁中段尿的污染率，对照组和改良组之间差异有统计学意义，P〈0．05；改进清洁中段尿的留取方法后，改良组清洁中段尿的污染率明显低于对照组。结论改进清洁中段尿留取方法后，可以明显降低清洁中段尿的污染率。

Objective To improve the collected method of middle clean urine and enhance the accuracy of clinical inspection. Methods 466 cases who collected the middle clean urine in outpatient service medical treatment rooms of our hospital from January 2010 to Januery 2012 were randomly divided into two groups ： control group （ n = 233 ）, improved group （ n = 233 ） . Middle clean urine of the control group were collected the according to conventional methods. Middle clean urine were collected by the homemade long handle and hollow out type chair according to improved methods in the improved group. The rate of pollution of two groups was compared. Results Middle clean urine was collected according to conventional methods. Compared the rate of pollution of the control group and the improved group, there was no significant difference between two groups （ P〉O. 05）. Middle clean urine was collected according to the improved methods. There was significant difference between two groups in the rate of pollution （P〈0. 05） . Conclusion After the collected method of middle clean urine has been improved, the rate of pollution can significantly reduce.
