Three patients had carcinoma of the stomach, rectum, and lung, respectively, metastatic to the ureter in the absence of other known metastasis. Two of the three patients had abdominal pain, while the other patient had no upper urinary tract symptoms. All patients had excretory urograms that showed delayed or no excretion of contrast medium on the side of obstruction. Obstruction was confirmed with retrograde pyelography in each case. Two of three patients were treated with nephrectomy. Metastatic carcinoma of the ureter should be considered in patients with malignant disease with initial symptoms consistent with ureteral obstruction. The diagnosis may be suggested by pyelographic demonstration of an obstructed ureter. Symptomatic patients may require nephrectomy.
三名患者分别患有胃癌、直肠癌和肺癌，均在无其他已知转移灶的情况下转移至输尿管。三名患者中有两名出现腹痛，另一名患者无上尿路症状。所有患者的排泄性尿路造影均显示梗阻侧造影剂排泄延迟或无排泄。每例均经逆行肾盂造影证实梗阻。三名患者中有两名接受了肾切除术。对于患有恶性疾病且初始症状与输尿管梗阻相符的患者，应考虑输尿管转移性癌。肾盂造影显示输尿管梗阻可能提示该诊断。有症状的患者可能需要进行肾切除术。
