We performed both kidney ultrasonography (KUS) and intravenous urography (IVU) in 56 children with urinary tract infections (UTI) to compare the effectiveness of these procedures in detecting urinary tract malformations (UTMs). In 7 patients where KUS findings were interpreted as normal, IVU detected the following UTMs: hydronephrosis (3), stenosis of the pelvi-ureteric junction (2), pelvi-ureteric duplication (1) and kidney dislocation (1). In 2 other patients, mild hydronephrosis diagnosed by KUS was not confirmed by IVU. With respect to IVU, KUS revealed a sensitivity of 77.4% and a specificity of 92%. In our experience, IVU is still irreplaceable in the diagnostic protocol of UTMs in children; KUS should be regarded as a useful complementary procedure.
我们对56例患有泌尿道感染（UTI）的儿童进行了肾脏超声检查（KUS）和静脉肾盂造影（IVU），以比较这些检查在检测泌尿道畸形（UTM）方面的有效性。在7例KUS检查结果被判定为正常的患儿中，IVU检测出了以下泌尿道畸形：肾积水（3例）、肾盂输尿管连接处狭窄（2例）、肾盂输尿管重复畸形（1例）和肾脏异位（1例）。在另外2例患儿中，KUS诊断的轻度肾积水未得到IVU的证实。就IVU而言，KUS的敏感性为77.4%，特异性为92%。根据我们的经验，IVU在儿童泌尿道畸形的诊断方案中仍然不可替代；KUS应被视为一种有用的辅助检查。
