Aorto-iliac aneurysms produce ureteric obstrucation by different mechanisms: deviation, compression and, above all, encirclement by peri-aneurysmal fibrosis. Whilst it is rare to find this as the cause for apparently primary ureteric obstruction, individuals with aorto-iliac aneumrysms quite often show evidence of ureteral abnormalities. The two cases presented illustrate these two possibilities. Routine pre-operative urography, or seven better a urographic phase of arteriography, is therefore suggested.
腹主动脉-髂动脉瘤通过不同机制导致输尿管梗阻：移位、压迫，尤其是被动脉瘤周围纤维化包绕。虽然将其作为明显原发性输尿管梗阻的病因较为罕见，但腹主动脉-髂动脉瘤患者常常有输尿管异常的表现。所呈现的两例病例说明了这两种可能性。因此，建议常规进行术前尿路造影，或者更好的是进行动脉造影的尿路造影期检查。
