There was little difference between the proportion of lesions found by excretion urography in patients with recurrent urinary tract infections referred by general practitioners or hospital staff, or between Horton General Hospital which is a district general hospital, and the United Oxford Hospitals, which is a teaching group. Many patients with urinary tract infections may be saved an unnecessary visit to the hospital consultant if this is first investigated by the general practitioner.About one fifth of all patients had significant lesions shown by excretory urography which suggests that the investigation is worthwhile in patients with recurrent urinary tract infections.
由全科医生或医院工作人员转诊的复发性尿路感染患者中，排泄性尿路造影发现病变的比例之间差异不大，地区综合医院霍顿综合医院与教学医院集团牛津联合医院之间也是如此。如果全科医生首先进行调查，许多尿路感染患者可能无需不必要地去看医院的专科医生。所有患者中约五分之一通过排泄性尿路造影显示有明显病变，这表明对复发性尿路感染患者进行该项检查是值得的。
