The kidneys are nearly always visible on a routine radionuclide bone scan. To assess the reliability of the bone scan in detecting ureteral obstruction, 220 bone scans and excretory urograms were compared in 53 patients followed serially for prostatic cancer. There were 15 kidneys obstructed on excretory urograms. Only nine were diagnosed as obstructed on the bone scans. Seven of the nine cases of unilaterally obstructed kidneys were detected, whereas only two of the six kidneys in three patients with bilateral obstruction were correctly diagnosed. The results indicate that unilateral obstruction is more likely to be detected, whereas bilateral obstruction is more likely to be missed, on bone scans. Therefore, the routine radionuclide bone scan is an unreliable test for ureteral obstruction.
在常规放射性核素骨扫描中，肾脏几乎总是可见的。为评估骨扫描检测输尿管梗阻的可靠性，对53例前列腺癌患者进行了连续随访，比较了220次骨扫描和排泄性尿路造影的结果。排泄性尿路造影显示有15个肾脏存在梗阻。骨扫描仅诊断出9个肾脏梗阻。9例单侧梗阻肾脏中，7例被检测到，而3例双侧梗阻患者的6个肾脏中，仅2例被正确诊断。结果表明，在骨扫描中，单侧梗阻更易被检测到，而双侧梗阻更易被漏诊。因此，常规放射性核素骨扫描对于输尿管梗阻是一项不可靠的检查。
