Although several cases of ureteral obstruction after vascular bypass surgery for aortoiliac disease have been reported, the incidence of this potentially critical complication has not been established. In this study, 57 selected patients who had undergone vascular bypass surgery were examined with ultrasound for evidence of ureteral obstruction. Hydronephrosis was discovered in 1 of 57 patients (1.75 per cent) over-all (symptomatic and asymptomatic); no evidence of obstruction was found in the asymptomatic patients. These results fail to corroborate the impression of several investigators that undetected ureteral obstruction may be present in a significant number of patients after vascular bypass surgery.
虽然已有关于主髂动脉疾病血管搭桥手术后输尿管梗阻的几例病例报告，但这种潜在严重并发症的发生率尚未确定。在本研究中，对57例接受血管搭桥手术的选定患者进行了超声检查，以寻找输尿管梗阻的证据。总体而言（有症状和无症状的患者），57例患者中有1例（1.75%）发现肾积水；无症状患者未发现梗阻迹象。这些结果未能证实一些研究者的观点，即血管搭桥手术后相当多患者可能存在未被发现的输尿管梗阻。
