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
评估磁共振尿路造影（MRU）在肾移植术后尿路梗阻诊断中的应用价值。
方法
对31例疑似肾移植术后尿路梗阻的患者进行检查，并将结果与手术及B超检查结果进行比较。
结果
MRU能清晰显示肾移植术后的尿路情况，所有患者均经MRU明确诊断。影像学结果与手术结果一致。
结论
MRU适用于检测肾移植术后的尿路梗阻。对于肾功能损害和尿毒症患者，它是替代静脉肾盂造影（IVP）和CT的一种检查方法。
