摘要目的 总结婴幼儿尿路感染的的临床资料,探讨和分析婴幼儿尿路感染的起病方式、临床特点.方法 对2004年9月至2008年5月确诊的104例婴幼儿尿路感染的临床资料作回顾性分析.结果 在所有确诊的尿路感染婴幼儿中,以<1岁的小婴儿为主,占61%;发热是最突出的起病方式,占75%;在选择性所做的86例肾静态显像(DMSA)检查中确诊急性肾盂肾炎(APN)42例(49%),其中3例已出现肾疤痕,进一步做排泄性膀胱造影(MCU)证实存在不同程度的膀胱输尿管返流(VUR)3例;在APN组,无论是<1岁小婴儿所占的比例,还是高热的发病数以及外周血白细胞计数和C反应蛋白(CRP)水平增高的比例都明显高于非APN组.结论 发热是婴幼儿尿感最重要的临床特点;婴幼儿尿感中APN的发病率不容忽视;小婴儿、高热和外周血白细胞计数和CRP水平的增高可能是APN发生的高危因素.

abstractsObjective To investigate the onset,clinical features of urinary tract infection in infants.Methods Retrospective analysis was performed on clinical data of 104 cases of urinary tract infection in infants from September 2004 to May 2008.Results Among those with confirmed urinary tract infection,61% were found with age less than one year old.Fever was the most common form of onset.accounting for 75%.42 cases (49%)of the 86 cases of selectively performed DMSA imaging were diagnosed as acute pyelonephritis(APN),3cases had scars formation.The proportion of young infants under one year of age,the number of high fever,and the proportion of increased peripheral white blood cells count and C-reactive protein(CRP)level were significantly higher than those without APN.Conclusion Fever is the most prominent clinical feature of urinary tract infection in infants and young children;the incidence of APN in urinary tract infection in infants and young children cannot be neglected;young infants,high fever,increased peripheral white blood cells count and level of CRP may be the risk factors of APN.
