女性泌尿系统病原学检测分析

目的 探讨女性泌尿系感染(UTI)病原菌的分布与特点,以提高临床诊治水平.方法 对129例以"尿道刺激症"为主诉的女性UTI患者的中段尿培养,阴道分泌物检测,并进行细菌学、支原体、衣原体、真菌、寄生虫鉴定.结果 129例女性UTI病原微生物为:革兰阴性菌(53.49%)、革兰阳性菌(19.38%),支原体(14.73%),真菌(9.30%)、衣原体(4.65%)、寄生虫(1.55%);其中分别又以大肠埃希菌、肺炎克雷伯菌、粪肠球菌、金黄色葡萄球菌感染多见;性传播疾病(27.91%)以非淋病性尿道炎多见;混合感染(17.38%)以解脲支原体合并其他感染为主,年龄多为青、中年.结论 女性UTI感染致病微生物以革兰阴性菌为主,性传播疾病、混合感染应引起临床医师重视,建议女性UTI患者常规进行病原学检测,以提高诊断治疗水平.

Etiological detective analysis in female urinary tract infection

Objective To discuss the disposition feature of pathogenic bacterium in female urinary tract infection(UTI) ,so as to elevate the level of clinical diagnosis and therapy. Methods To cultivate medistream urine,assess vaginal secretions in the aspects of bacteriology, mycoplasma, chlamydia, mycetes and parasite. All specimen collected from 129 female patients who chiefly complained irritation of urinary tract ,from January 2003 to December 2006. Results Pathogenic microorganisms that found in the 129 female patients with UTI are gram-negative bacteria( 53.49 % ), gram- positive bacteria ( 19.38 % ), mycoplasma ( 14.73 % ), mycetes (9.30 % ), chlamydia (4.65 % ),parasite(1.55% ). Among them, escherichia coli, klebsiella pneumoniae bacilli, enterococcus faecalis, staphylococcus aureus are common species. Sexually transmitted disease(27.91% ) include the infection of diplococcus gonorrhoeae,mycoplasma and ehoamydiae. Among them,non-gonococcal urethritis is common. Combined infection(17.38 % ). Infection combined with mycoplasma urealytium and other pathogen is the most, these patients are most young or middle aged. Conclusion Pathogen in female UTI is mostly gram-positive bacteria. STD and combined infection should be paid attention to by clinicians. We suggest female UTI patients take etiological test regularly,so as to elevate the level of clinical diagnosis and therapy.
