本研究采用亚甲基蓝（美蓝）染色检查男性尿道炎患者尿道多形核白细胞数量并进行解脲脲原体（Ureaplasma urealyticum，Uu）培养，以评价非淋病奈瑟菌性尿道炎（NGU）的临床意义。2284例性病患者的尿道分泌物涂片，美兰染色镜检多形核白细胞和尿道分泌物的解脲脲原体体外培养。2284例性病患者中，645例患者（28.2%）Uu培养阳性。 在Uu阳性患者中，158例（24.5%）≥5个多形核白细胞,157例（24.3%）为1-4个多形核白细胞, 330例（51.2%）为0个多形核白细胞，其中218例阳性患者（33.8%）无症状，614例阳性患者（95.9%）无体征。 男性尿道炎患者尿道多形核白细胞数量在解脲脲原体感染中存在明显差异（P<0.001）,此结果表明临床诊断与实验室检查在证实男性非淋病奈瑟菌性尿道炎中具有重要意义。

In the current stady, the polymorphonuclear leukocyte(PMNL) count bymethyl blue stain and Ureaplasma urealyticum culture were used in male patients with urethral inflammation. The goal of this study was to determine a relationship between Ureaplasma urealyticum infectios and clinical characteristics of urethral inflammation. Two thousand two hundred and eighty –four men seeking treatment for suspected swxually transmitted diseases were enrolled to evaluate increased urethral PMNL count. Specimens were examined for presence of the Ureaplasma urealyticum through culture. Among 2,284 eligible men, 645(28.2%) had Ureaplasma urealyticum -infeced. Among Ureaplasma urealyticum-infeced men, PMNLS per oil-immersion field were ≥5 in 158(24.5%), 1 to 4 in 157(24.3%),and none in 330(51.2%)，218(33.8%) and 614(95.2 %) in men were asympomati or signs at that stage or their infection. Ureaplasma urealyticum infections showed significantly high levelss of urethral inflammation in male patients as measured by PMNLsand PMNLs (P<0.001). Tese results indicate that both clinical diagnosis and laboratory testing are important in confirming urethral inflammation male patients.
