对72例经清洁中段尿细菌培养阳性,细菌计数≥105/ml,确诊为UTI的DN病人的临床特点与细菌学进行分析。结果:72例DN并UTI病人中有症状者14例,占19.44%(14/72),有典型膀胱刺激征(尿急、尿频、尿痛)者仅5例,(6.94%),9例临床表现均不典型。其余58例无任何临床症状仅为无症状性菌尿(ASP),占80.55%,(58/72)。UTI的致病菌以革兰氏阴性杆菌为主,占81.33%,大肠埃希氏菌为优势菌株,占50.67%(38/75),其次为变形杆菌9.33%(7/75),枸橼酸杆菌5.34%(4/75),肺炎克雷白氏杆菌9.33%(7/75)。球菌占16.00%(12/75),其中肠球菌8.00%(6/75),表皮葡萄球菌4.00%(3/75)。白色念珠菌2.67%(2/75)。大肠埃希氏菌对氨苄青霉素、头孢唑林、环丙沙星、左氧氟沙星、庆大霉素等抗生素的耐药率较高。结论:DN并UTI者的临床症状不典型,以无症状性菌尿(ASP)为多见。以革兰氏阴性杆菌为主,耐药率高。
The clinical features and bacteriological characteristics of 72 DN patients diagnosed as UTI with positive urine bacterial culture in the middle of the diagnosis, bacterial count≥105 / ml were analyzed. Results: Of the 72 patients with DN and UTI, 14 were symptomatic (19.44%, 14/72). Only 5 patients (6.94%) had typical bladder irritation (urinary urgency, frequent urination, dysuria) and 9 Clinical manifestations are not typical. The remaining 58 cases without any clinical symptoms only asymptomatic bacteriuria (ASP), accounting for 80.55%, (58/72). The pathogens of UTI were mainly Gram-negative bacilli, accounting for 81.33%. Escherichia coli was the dominant strain accounting for 50.67% (38/75), followed by Proteus (9.33%, 7/75) Acidobacillus 5.34% (4/75), Klebsiella pneumoniae 9.33% (7/75). Cocci accounted for 16.00% (12/75), including Enterococcus 8.00% (6/75), Staphylococcus epidermidis 4.00% (3/75). Candida albicans 2.67% (2/75). Escherichia coli ampicillin, cefazolin, ciprofloxacin, levofloxacin, gentamicin and other antibiotics resistant rate is higher. Conclusion: The clinical symptoms of DN and UTI are not typical, with asymptomatic bacteriuria (ASP) is more common. Gram-negative bacilli-based, high resistance rate.
