Diuretic renography has been recommended as a useful test to distinguish obstructed from dilated, but not obstructed, urinary systems. Twenty-four diuretic renograms were performed in 20 children, and a good correlation was found with other indicators of obstruction. The sensitivity for identifying obstruction was 83%, with a specificity of 94%. Severe hydroureteronephrosis may blunt or even mask the effect of diuresis on causing emptying of the tracer from the renal pelvis. Some kidneys did not drain well with the patient in a supine position but did empty with a change of position; these kidneys should be regarded as nonobstructed.
利尿肾图已被推荐作为一种有用的检查方法，用于区分梗阻性与扩张但无梗阻的泌尿系统。对20名儿童进行了24次利尿肾图检查，发现其与其他梗阻指标具有良好的相关性。识别梗阻的敏感性为83%，特异性为94%。严重的输尿管肾盂积水可能会减弱甚至掩盖利尿对示踪剂从肾盂排出的影响。有些肾脏在患者仰卧位时引流不畅，但改变体位后却能排空；这些肾脏应被视为无梗阻。
