Mean pulmonary function was significantly decreased in 57 patients during excretory urography. Patients with a history of allergy had significantly greater mean decreases in flow rates than those without. Twelve did not have significant decreases in pulmonary function after needle puncture and intravenous injection of 5% dextrose in water. Eight healthy subjects did not have significant mean decreases after intravenous injection of 5% saline. Most patients undergoing excretory urography have bronchospasm that is greater in magnitude in those with a history of allergy.
57例患者在排泄性尿路造影期间肺功能均值显著下降。有过敏史的患者流速平均下降幅度显著大于无过敏史者。12例患者在穿刺及静脉注射5%葡萄糖水溶液后肺功能无显著下降。8名健康受试者静脉注射5%盐水后平均下降幅度不显著。大多数接受排泄性尿路造影的患者存在支气管痉挛，有过敏史者的支气管痉挛程度更严重。
