摘要
[摘要 ] 目的 观察尿液细菌培养与尿沉渣细菌定量计数筛查泌尿系统感染的准确率，分析尿沉渣细菌定量计数的临床价值。方法 选取 2017年 10月～ 2018年 10月期间我院门诊以及住院患者的尿液样本 174份作为研究对象。采用尿沉渣定量分析仪和尿液细菌培养对 174份尿液样本进行检测，比较两种方法的检测结果，分析尿沉渣细菌定量计数的临床检测价值。 结果 174例尿液样本尿液细菌培养检测结果显示，呈现阳性的有 20例，阳性率为 11.49%；呈现阴性的有 154例，阴性率为 88.51%。尿沉渣细菌定量计数筛查显示，呈现阳性的有 21例，阳性率为 12.07%；呈现阴性的有 153例，阴性率为 87.93%。两组阳性率和阴性率比较差异无统计学意义（ P>0.05）。尿沉渣细菌定量计数检测的阳性预测值为 50.0%，阴性预测值为 82.2%，两者比较差异具有统计学意义（ P<0.05）。结论 尿沉渣细菌定量检测可以作为泌尿系统感染的检测方法，阴性预见性较高，但不能完全取代尿液细菌培养。

[abstract] Objective To observe the accuracy of urinary bacterial culture and urinary sediment bacterial quantitative count in screening urinary tract infection, and to analyze the clinical value of urinary sediment bacterial quantitative count. Methods 174 urine samples from outpatients and inpatients in our hospital from October 2017 to October 2018 were selected as the study subjects. 174 urine samples were detected by urine sediment quantitative analyzer and urine bacterial culture. The results of the two methods were compared and the clinical value of urine sediment bacterial quantitative counting was analyzed. Results Among 174 urine samples, 20 were positive (11.49%) and 154 were negative (88.51%). Quantitative counting and screening of urinary sediment bacteria showed that 21 cases were positive, the positive rate was 12.07%, 153 cases were negative, the negative rate was 87.93%. There was no significant difference in the positive and negative rates between the two groups (P > 0.05). The positive predictive value and the negative predictive value of quantitative counting of urinary sediment bacteria were 50.0% and 82.2%, respectively. The difference was significant (P < 0.05). Conclusion Quantitative detection of urinary sediment bacteria can be used as a detection method for urinary tract infection. The negative predictability is high, but it can not completely replace urinary bacterial culture.
