In 50 patients with obstructive uropathy, nuclear imaging supplementary to excretory urography did not improve the detection of obstruction or the determination of the site or etiology of the lesion. However, rapid sequential radionuclide images showed decreased renal perfusion in 64%, more frequently than did an obstructive nephrogram (40%); this finding appeared to occur with more severe degrees of obstruction. Functional impairment of the obstructed kidney was demonstrated more often with 131I Hippuran (o-iodohippurate sodium) (91%) than with 99mTc glucoheptonate (68%) or excretory urography (66%). Neither nuclear nor urographic studies could predict the degree of functional recovery of the kidney until the increased intrapelvic pressures was relieved.
在50例梗阻性尿路病患者中，排泄性尿路造影辅以核素成像并未改善梗阻的检测或病变部位及病因的判定。然而，快速序列放射性核素影像显示64%的患者肾灌注减少，比梗阻性肾图（40%）更常见；这一发现似乎在梗阻程度更严重时出现。与99m锝葡庚糖酸盐（68%）或排泄性尿路造影（66%）相比，131碘马尿酸（邻碘马尿酸钠）更常显示梗阻肾脏的功能损害（91%）。在肾盂内压力升高缓解之前，核素检查和尿路造影检查均无法预测肾脏功能恢复的程度。
