Urinary tract infection contributes to the morbidity of pregnancy since 4-10 percent of antepartum patients have asymptomatic bacteriuria and 20-40 percent of these will result in pyelonephritis. A cost-effective outpatient assessment for asymptomatic bacteriuria in undelivered obstetric patients is described. In this study, 56 patients between 6-24 weeks gestation were assessed over a seven-month period by photometric urinary screening. This assessment was more accurate in identifying those patients with asymptomatic bacteriuria than prior history or symptoms. A 7 percent incidence of asymptomatic bacteriuria was noted with 75 percent being Escherichia coli and the remainder Klebsiella. Single-dose, oral antibiotic therapy was evaluated and resulted in no recurrences. Such screening for asymptomatic bacteriuria was felt to represent preventive and economic medical benefits.
尿路感染会导致妊娠并发症，因为4%至10%的产前患者有无症状菌尿，其中20%至40%会发展为肾盂肾炎。本文描述了一种针对未分娩产科患者无症状菌尿的经济有效的门诊评估方法。在本研究中，对56例妊娠6至24周的患者在七个月的时间里进行了尿液光度筛查评估。这种评估在识别无症状菌尿患者方面比既往病史或症状更准确。无症状菌尿的发生率为7%，其中75%为大肠杆菌，其余为克雷伯菌。对单剂量口服抗生素治疗进行了评估，结果无复发。这种对无症状菌尿的筛查被认为具有预防和经济方面的医疗益处。
