尿路感染（UTI）是婴儿期发热的一种相对常见的原因，通常由肾盂肾炎组成，并可能导致永久性肾损伤。本研究评估了（1）具有不同人口统计学和临床特征的发热婴儿（体温≥ 38.3 ℃）中UTI的患病率和（2）尿分析在诊断UTI中的有用性。我们在945名发热婴儿中发现50名（5.3%）在通过导管插入术获得的尿液标本中发现大于或等于10，000个菌落形成单位的单一病原体/毫升，诊断为UTI。患病率在以下婴儿中相似：（1）小于或等于2个月的婴儿接受败血症检查（4.6%），（2）年龄>2个月的婴儿怀疑UTI，通常是因为没有明显的发热源（5.9%），和（3）没有怀疑UTI的婴儿，其中大多数有其他疾病（5.1%）。女性和白色婴儿的UTI明显多于男性和黑人婴儿。总的来说，体温高于或等于39 ℃的白色女婴中有17%患有UTI，显著高于（p
Urinary tract infection (UTI), a relatively common cause of fever in infancy, usually consists of pyelonephritis and may cause permanent renal damage. This study assessed (1) the prevalence of UTI in febrile infants (temperature greater-than-or-equal-to 38.3-degrees-C) with differing demographic and clinical characteristics and (2) the usefulness of urinalysis in diagnosing UTI. We diagnosed UTI in 50 (5.3%) of 945 febrile infants it we found greater-than-or-equal-to 10,000 colony-forming units of a single pathogen per milliliter in a urine specimen obtained by catheterization. Prevalences were similar in (1) infants aged less-than-or-equal-to 2 months undergoing examination for sepsis (4.6%), (2) infants aged >2 months in whom UTI was suspected, usually because no source of fever was apparent (5.9%), and (3) infants with no suspected UTI, most of whom had other illnesses (5.1%). Female and white infants had significantly more UTIs, respectively, than male and black infants. In all, 17% of white female infants with temperature greater-than-or-equal-to 39-degrees-C had UTI, significantly more (p
