目的:观察尿常规检测诊断在尿路感染中的价值和临床效果。方法:选取2013年8月至2016年7月东莞市虎门中医院收治的疑似尿路感染患者100例作为观察对象。对所有患者均进行尿亚硝酸盐和白细胞检测,观察其与尿细菌培养之间的关系,对比两种检测方式的敏感度、特异度以及准确性。结果:尿细菌培养中,阳性32例,阳性率为32.00%,其中白细胞阳性预测值为78.13%,阴性预测值为72.59%;敏感度为56.82%、特异度为87.50%、准确性为44.00%;亚硝酸盐阳性预测值为31.25%,阴性预测值为69.12%;敏感度、特异度以及准确性分别为32.26%、68.12%、31.00%,与尿细菌培养对比,白细胞检测效果更佳,差异具有统计学意义(P<0.05);结论:白细胞检测的敏感度、特异度以及准确性均较高,临床价值较显著。 Objective: To observe the value and clinical effect of urine routine test in urinary tract infection. Methods: From August 2013 to July 2016, Humen Hospital of Traditional Chinese Medicine, Dongguan City, 100 cases of suspected urinary tract infection were selected as the observation object. All patients were tested for urinary nitrite and leukocyte count. The relationship between urine nitrite and leukocyte count was observed. The sensitivity, specificity and accuracy of the two methods were compared. Results: In the urine culture, the positive rate was 32.00%. The positive predictive value of leucocyte was 78.13%, the negative predictive value was 72.59%, the sensitivity was 56.82%, the specificity was 87.50% and the accuracy was 44.00% ; The positive predictive value of nitrite was 31.25%, the negative predictive value was 69.12%; the sensitivity, specificity and accuracy were 32.26%, 68.12%, 31.00%, respectively. Compared with the culture of urine, the detection of leukocyte was better, (P <0.05). CONCLUSION: The sensitivity, specificity and accuracy of leukocyte detection are high and the clinical value is significant.
