The strong association between kidney and urinary tract anomalies and childhood urinary tract infection (UTI) often leads to imaging tests being performed. -Objective: To describe the epidemiology, characteristics, and imaging findings in Thai children with UTI and compare results between boys and girls.
We retrospectively reviewed the medical records of children with UTI aged < 15 years. Demographic characteristics and findings of investigations are presented.
One hundred seventy-eight boys and 170 girls with 432 UTI episodes were identified. The median (interquartile range) age at presentation was 1.4 (0.6-3.4) years, 1.0 for boys and 2.1 for girls (p < 0.001). Renal ultrasound, voiding cystourethrogram and 99mTc dimercaptosuccinic acid (DMSA) renal scans were performed in 273, 223 and 113 children, respectively. Overall, 283 children (81.3%) had at least one imaging study done and anomalies of the kidney and urinary tract were detected in 158 (45.4%). Primary vesicoureteral reflux was detected in 73 (32.7%) children. The remaining abnormalities were hydronephrosis (n = 54). DMSA scans detected 54 children with dysplastic or scarred kidneys.
First UTI in a group of Thai children occurred in approximately equal proportion in boys and girls but boys were younger at diagnosis. Kidney and urinary tract anomalies were detected in half of the children.
肾脏和尿路异常与儿童尿路感染（UTI）之间的密切关联常常导致进行影像学检查。目的：描述泰国UTI患儿的流行病学、特征及影像学表现，并比较男孩和女孩的结果。
我们回顾性分析了年龄＜15岁的UTI患儿的病历。呈现了人口统计学特征及检查结果。
共确定了178名男孩和170名女孩，发生了432次UTI发作。就诊时的中位（四分位间距）年龄为1.4（0.6 - 3.4）岁，男孩为1.0岁，女孩为2.1岁（p＜0.001）。分别对273名、223名和113名儿童进行了肾脏超声、排尿性膀胱尿道造影和99mTc二巯基丁二酸（DMSA）肾扫描。总体而言，283名儿童（81.3%）至少进行了一项影像学检查，其中158名（45.4%）检测到肾脏和尿路异常。73名（32.7%）儿童检测到原发性膀胱输尿管反流。其余异常为肾积水（n = 54）。DMSA扫描检测到54名患有发育异常或瘢痕肾的儿童。
在一组泰国儿童中，首次UTI在男孩和女孩中的发生率大致相等，但男孩诊断时年龄更小。一半的儿童检测到肾脏和尿路异常。
