Abstract

Aim: This study aimed to investigate the occurrence of urinary tract abnormalities detected in the ultrasound screening of children after a urinary tract infection episode, regardless of their age.

Methods: This cohort study included children aged 0-16 years who underwent urinary tract ultrasound screening after a urinary tract infection between January 1, 2004, and December 31, 2015 in a paediatric university hospital in Finland. We excluded children with previously diagnosed pathologies of the urinary tract.

Results: A total of 2050 children were included in this study. Among these, 116 (5.7%, 95% confidence interval 4.7%-6.7%) children had an abnormal ultrasound. In children with pyelonephritis, 70% of the abnormal ultrasounds were found in children younger than 2 years old. Age younger than 2 years was not associated with an increased risk of abnormality (odds ratio: 0.99, 95% confidence interval 0.65-1.52). Boys and children with non-Escherichia coli urinary tract infection or recurrent urinary tract infection were associated with a higher risk of having a urinary tract abnormality.

Conclusion: Limiting ultrasound screening after pyelonephritis to children under 2 years of age, as recommended in many current treatment guidelines, may miss a significant proportion (30%) of children with urinary tract abnormalities.

儿童尿路感染后超声异常表现。

目的：本研究旨在探讨尿路感染后超声筛查发现的儿童尿路异常的发生情况，而不考虑其年龄。方法：本队列研究纳入了2004年1月1日至2015年12月31日在芬兰一家儿科大学医院接受尿路感染后尿路超声筛查的0-16岁儿童。我们排除了先前诊断出泌尿道病变的儿童。结果：本研究共纳入儿童2050例。其中超声异常116例（5.7%，95%可信区间4.7% ~ 6.7%）。在肾盂肾炎患儿中，70%的超声异常发生在2岁以下的儿童。年龄小于2岁与异常风险增加无关（优势比：0.99,95%可信区间为0.65-1.52）。非大肠杆菌尿路感染或复发性尿路感染的男孩和儿童发生尿路异常的风险较高。结论：根据目前许多治疗指南的建议，肾盂肾炎后的超声筛查仅限于2岁以下的儿童，可能会错过很大比例（30%）的尿路异常儿童。
