Fifty-nine pediatric patients with urinary tract infection (UTI) underwent renal ultrasonography, excretory urography, and voiding cystourethrography. The imaging procedures were analyzed retrospectively to determine their relative effectiveness in detecting abnormalities that might predispose the patient to UTI. Voiding cystourethrography provided valuable information, particularly the presence or absence of vesicoureteral reflux, that could not be obtained from the other procedures. Excretory urography was less specific than ultrasonography in the majority of patients, with the exception of those who had renal scarring. The authors recommended ultrasonography as the initial imaging procedure in the evaluation of children with UTI. When the sonogram is normal, excretory urography is not considered necessary, but voiding cystourethrography is thought to be essential. If sonography is abnormal, excretory urography and/or other follow-up studies are indicated.
59例患有泌尿道感染（UTI）的儿科患者接受了肾脏超声检查、排泄性尿路造影和排尿性膀胱尿道造影。对这些影像学检查进行回顾性分析，以确定它们在检测可能使患者易患UTI的异常情况方面的相对有效性。排尿性膀胱尿道造影提供了有价值的信息，特别是有无膀胱输尿管反流，这是其他检查无法获得的。除了有肾瘢痕的患者外，在大多数患者中，排泄性尿路造影的特异性低于超声检查。作者建议将超声检查作为评估UTI患儿的初始影像学检查。当超声检查正常时，不认为有必要进行排泄性尿路造影，但排尿性膀胱尿道造影被认为是必不可少的。如果超声检查异常，则需要进行排泄性尿路造影和/或其他后续检查。
