磁共振尿路水成像对诊断上尿路梗阻病变的价值

The value of magnetic resonance urography in the diognosis of upper urinary tract obstruction

目的 :探讨磁共振尿路水成像 (MRU)对诊断上尿路梗阻病变的价值。方法 :回顾分析了 5 2例上尿路梗阻患者的MRU的临床资料。结果 :5 2例患者经过MRU检查均能显示梗阻的部位 ,5 0例与手术后诊断或治疗后明确的诊断相符合 ,2例误诊。结论 :MRU能准确地显示尿路梗阻病变的部位和大小 ,具有无创伤、无痛苦、无辐射、不需造影剂及多平面成像能力等特点 ,比临床上常用的B超、静脉肾盂造影、逆行肾盂造影等检查具有一定的优越性。

Objective:To evaluate the diagnostic efficacy of magnetic resonance urography(MRU) in patients with upper urinary tract obstruction.Method:Fifty-two patients with upper urinary tract obstruction were subjected to MRU.Result:The sites of urinary tract obstruction were distinctly shown in 52 of 52. Two patients were misdiagnosed by MRU before operation.Conclusion:MRU is noninvasive and is free from ionzing radiation or iodinated contrast medium. It had more supper diagnostic efficacy than ultrasound B, IVU and retrography.
