Aorto-iliac aneurysms may entrap the ureters in perianeurysmal fibrosis, causing medical ureteral deviation and/or obstruction. The latter has been described only in male patients; a further 5 cases due to iliac and 3 to aortic aneurysm are reported. The radiologic picture resembles retroperitoneal fibrosis; the correct diagnosis may be suggested when ureteral tethering or narrowing lies near arterial calcification. Sonography is usually the most appropriate investigation to confirm the diagnosis. When sonography shows an aortic aneurysm, the kidneys should be scanned to rule out hydronephrosis. Similarly, films of the kidneys should be obtained when an abdominal aneurysm is demonstrated by aortography.
腹主动脉-髂动脉瘤可能会因动脉瘤周围纤维化而压迫输尿管，导致医源性输尿管移位和/或梗阻。后者仅在男性患者中有所描述；本文报告了另外5例因髂动脉瘤和3例因腹主动脉瘤导致的病例。影像学表现类似于腹膜后纤维化；当输尿管束带或狭窄靠近动脉钙化时，可能提示正确诊断。超声检查通常是确诊的最合适检查方法。当超声显示腹主动脉瘤时，应扫描肾脏以排除肾积水。同样，当主动脉造影显示腹主动脉瘤时，应拍摄肾脏X光片。
