Fifty-one children with a bacteriologically proven urinary tract infection had both an intravenous urogram (IVU) and a micturating cystogram. The IVU was normal in 35. Only 6 of these children showed reflux in the cystogram, affecting 7 of the 70 ureters at risk. Since reflux on its own does not cause renal damage, which occurs only with super-added infection, detection of reflux is not important providing the urine is kept sterile. We suggest that cystography be deferred providing the IVU is normal until recurrent infections occur while under hospital care, and, with this policy this unpleasant and sometimes hazardous investigation could be avoided in many children with a single urinary tract infection.
51名经细菌学证实患有泌尿道感染的儿童接受了静脉肾盂造影（IVU）和排尿性膀胱造影。35名儿童的IVU结果正常。这些儿童中只有6名在膀胱造影中显示有反流，70条有风险的输尿管中有7条受到影响。由于反流本身不会导致肾损伤，肾损伤仅在叠加感染时发生，所以只要尿液保持无菌，检测反流就不重要。我们建议，如果IVU正常，在医院护理期间直到反复感染发生之前，可推迟膀胱造影，采用这一策略可避免许多单次泌尿道感染儿童接受这种不愉快且有时有风险的检查。
