A trial of the value of diuresis renography in equivocal upper urinary tract obstruction is presented. Fifty-two patients were examined by standard renography and renography under a diuretic provocation. The results indicate that the technique is of considerable value in making the vital distinction between dilatation on the excretion urogram due to atonicity and that caused by a genuine obstruction. A quantitative index of the response to diuresis reflecting the degree of impedance to flow is described--the Diuresis Excretion Index. Diuresis renography is recommended in the evaluation of the patient with equivocal urinary tract obstruction.
本文介绍了利尿肾图在诊断不明确的上尿路梗阻中的价值试验。52例患者接受了标准肾图检查以及利尿激发试验下的肾图检查。结果表明，该技术对于鉴别排泄性尿路造影上因张力缺乏导致的扩张与真正梗阻导致的扩张具有重要价值。文中描述了一种反映流量阻抗程度的利尿反应定量指标——利尿排泄指数。对于尿路梗阻诊断不明确的患者，推荐采用利尿肾图进行评估。
