Twenty-two patients with intermittent loin pain thought to be typical of primary pelvic hydronephrosis but with normal appearances at standard excretion urography were subjected to diuretic urography using Frusemide-induced diuresis. If this was normal, acute urography was performed when the patient had pain. Abnormal appearances were shown in only 15 patients. In 4, only the erect films revealed the hydronephrosis. Dilatation occurred in response to a diuretic load in 9 and the abnormality was shown at the time of an attack of pain in 4. The hydronephrosis was shown only during the attack of pain in 2, a diuretic urogram having been normal. In 2 patients the nephrographic signs of acute obstruction were shown to be due to occlusion of the pelvi-ureteric junction at the time of an attack of pain. The importance of sequential examination, the value of erect films and acute urography are stressed.
22例间歇性腰痛患者，其症状被认为是典型的原发性肾盂积水，但标准排泄性尿路造影显示正常，对这些患者采用速尿诱导利尿进行利尿性尿路造影。如果结果正常，则在患者疼痛时进行急性尿路造影。仅15例患者出现异常表现。4例患者仅立位片显示肾盂积水。9例患者对利尿负荷有反应出现扩张，4例患者在疼痛发作时显示异常。2例患者仅在疼痛发作时显示肾盂积水，利尿性尿路造影正常。2例患者急性梗阻的肾造影征象显示是由于疼痛发作时肾盂输尿管连接处阻塞所致。强调了序贯检查、立位片和急性尿路造影的价值。
