CT findings in three cases of ureteral metastases are reported. Metastases to the ureter is an uncommon cause of the upper urinary tract obstruction. The most common primary sites include breast, stomach and neoplasms from pelvic organs. Radiographic studies revealed an ureteral stenosis in all the presenting cases. CT scans demonstrated a thickened regular ureteral wall at the level of the narrowing and no other abnormalities of the retroperitoneum. Such CT features suggest the possibility of ureteral metastases in a patient with the appropriate clinical setting. Histological studies, whenever possible, must confirm these radiographic findings. Early recognition of ureteral metastases and appropriate treatment for relief of urinary tract obstruction may prolong survival time.
报告了3例输尿管转移瘤的CT表现。输尿管转移是上尿路梗阻的罕见原因。最常见的原发部位包括乳腺、胃和盆腔器官的肿瘤。影像学检查显示所有病例均有输尿管狭窄。CT扫描显示狭窄部位输尿管壁规则增厚，腹膜后无其他异常。这些CT特征提示在有适当临床背景的患者中存在输尿管转移的可能性。只要有可能，组织学研究必须证实这些影像学表现。早期识别输尿管转移并采取适当治疗以缓解尿路梗阻可能会延长生存时间。
