目的分析泌尿外科尿路感染患者细菌培养阳性检出率、致病菌构成和药敏试验结果。方法选取四川省射洪县中医院泌尿外科2013—2015年收治的尿路感染患者清洁中段尿473份,分析尿路感染患者细菌培养阳性检出率、致病菌构成和药敏试验结果。结果采集的473份尿标本中培养出致病菌株179株,以肠杆菌科致病菌居多,真菌次之,肠球菌第三。根据选药提示肠杆菌科敏感性最高的是美罗培南,丁胺卡那霉素次之,妥布霉素敏感性最高,泌尿道首选药诺氟沙星敏感性最高。对真菌敏感性最高的是氟胞嘧啶和两性霉素。对肠球菌敏感性最高的是万古霉素和利奈唑胺,环丙沙星敏感性最高。结论泌尿外科尿路感染的致病菌主要为肠杆菌科、真菌和肠球菌,治疗用抗生素应首选诺氟沙星和妥布霉素、环丙沙星和氟胞嘧啶、两性霉素。
Objective To analyze the positive rate of bacterial culture in urinary tract infections in urology patients, the constitution of pathogenic bacteria and the drug susceptibility test results. Methods 473 urinary tract infections in patients with urinary tract infection were collected from the Urology Department of Shehong Hospital of Traditional Chinese Medicine in Shehong County, Sichuan Province in 2013-2015. The positive rate of bacterial culture, pathogenic bacteria and drug susceptibility test results were analyzed. Results A total of 179 strains of pathogens were cultured in 473 urine samples collected, with the majority of Enterobacteriaceae pathogens, fungi second, and enterococci third. According to the selection of drugs prompted the highest sensitivity of Enterobacteriaceae Meropenem, followed by amikacin, tobramycin has the highest sensitivity, urinary tract preferred drug norfloxacin the highest sensitivity. The most susceptible fungi are flucytosine and amphotericin. Vancomycin and linezolid are the most sensitive to enterococci, and ciprofloxacin has the highest sensitivity. Conclusions Urinary tract infection urinary tract pathogens mainly Enterobacteriaceae, fungi and enterococci, norfloxacin and tobramycin, ciprofloxacin and flucytosine, amphotericin.
