摘要
OBJECTIVE: To evaluate magnetic resonance urography (MRU) in the diagnosis of urinary tract obstruction after renal transplantation. METHODS: A total of 31 patients with suspected urinary tract obstruction after renal transplantation were examined, and the results were compared with those from surgery and B-ultrasound examination. RESULTS: The urinary tract after renal transplantation was clearly shown using MRU, and all patients were clearly diagnosed by MRU. Imaging results were consistent with those from surgery. CONCLUSIONS: MRU is suitable for detecting urinary tract obstruction after renal transplantation. It is a alternative method for IVP and CT in patients with renal function impairment and uremia.
目的评价磁共振水成像(MRU)在肾移植术后尿路梗阻中的诊断价值.方法对31例肾移植术后怀疑尿路梗阻的患者,使用重T2加权FSE序列,脂肪抑制技术和兴趣向量技术进行检查,附手术和B超做对照.结果 MRU可充分显示肾移植后患者尿路的影像.依据MRU影像,确诊率为100%.影像与手术所见基本一致.结论 MRU适用于肾移植术后尿路梗阻的检查(尿瘘、吻合口狭窄、肿瘤等).在肾功能受损、尿毒症的患者中,它可能是取代IVP和CT的良好的检查方法.
