目的比较RNA与DNA检测技术对常见男性泌尿生殖道性传播疾病病原体检测效能。方法收集因孕前检查来同仁医院门诊就诊的男性患者精液样本,采用DNA检测技术进行沙眼衣原体(CT)、淋病奈瑟菌(NG)和解脲脲原体(UU)检测,同时使用RNA检测技术对尿液样本中的3种病原体进行检测,分析RNA检测试剂盒的诊断灵敏度及特异度,比较检测效能。结果在510例尿液样本中,RNA检测试剂盒对3种病原体总体诊断灵敏度为84.48%,特异度为85.71%,曲线下面积(AUC)为0.851(95%CI:0.818~0.884)。对CT的诊断灵敏度为73.33%,特异度为97.56%,AUC为0.854(95%CI:0.738~0.971)。对UU+UP的诊断灵敏度为83.95%,特异度为88.79%,AUC为0.864(95%CI:0.831~0.897)。精液UU阳性的162例患者中,其尿液样本中43例为UU阳性,97例为UP阳性,总阳性率为(140/162)86.42%。结论RNA技术检测尿液样本性传播相关病原体的诊断效能与DNA检测技术相似。
