A review of 22,971 pregnancies from 1969-74 reveals that the reasons for requesting excretory urography were renal colic of pregnancy 11, pyelonephritis 8, renal contusion 2, threatened abortion 1, and suspected degeneration of fibroid 1. The final diagnoses were similar except that two patients with torsion of ovarian cysts and a renal calculus were discovered. The only intravenous pyelographic examination that was decisive for diagnosis was in a patient with a ureteric calculus. Careful clinical correlation should reduce excretory urography during pregnancy.
对1969年至1974年期间的22971例妊娠进行的一项回顾显示，要求进行排泄性尿路造影的原因包括：妊娠肾绞痛11例、肾盂肾炎8例、肾挫伤2例、先兆流产1例、疑似子宫肌瘤变性1例。最终诊断结果相似，只是发现了两名患有卵巢囊肿扭转和肾结石的患者。唯一对诊断起决定性作用的静脉肾盂造影检查是在一名患有输尿管结石的患者身上进行的。仔细的临床关联应可减少孕期的排泄性尿路造影检查。
