摘要
目的研究尿沉渣白细胞计数和细菌计数对诊断男性淋菌性尿道炎的价值。方法采用UF-1000i全自动尿液分析仪对140例临床诊断男性尿道炎患者的尿液样本进行尿沉渣白细胞计数和细菌计数,同时将尿液样本浓缩涂片,行革兰染色镜检,查见革兰阴性双球菌为淋菌性尿道炎确诊病例。计算尿沉渣白细胞计数和细菌计数对诊断男性淋菌性尿道炎的敏感性、特异性等评估参数。结果尿白细胞计数≥300个/μL、细菌计数≤300个/μL时诊断淋菌性尿道炎的敏感性为92.0%,特异性为80.0%,阳性预测值为71.9%,阴性预测值为94.7%,受试者工作特征(ROC)曲线下面积为0.824。结论尿沉渣白细胞计数和细菌计数对诊断男性淋菌性尿道炎有一定价值。
Objective To investigate the diagnosis significance of urinary leukocyte count and bacterium count for male gonoeoeeal urethritis. Methods A total of 140 urine specimens for male patients with urethritis were determined for urinary leukocyte count and bacterium count by UF-1000i automatic urine analyzer, which the samples were then concentrated and smeared. The specimens of Gram-negative diplococcus were confirmed as the cases of gonococcal urethritis. The evaluation parameters such as sensitivity and specificity were counted statistically to diagnose male gonococcal urethritis. Results The sensitivity was 92.0%, the specificity was 80.0%, the positive predictive value was 71.9% , the negative predictive value was 94.7% , and the area under receiver operating characteristic （ROC） curve was 0. 824 for diagnosing gonococcal urethritis, when urinary leukocyte count was ≥ 300/μL, and bacterium count was ≤300/μL. Conclusions Urinary leukocyte count and bacterium count show significance in the diagnosis of male gonococcal urethritis.
