摘要
目的:评价静脉尿路造影技术(IVU)与低场强磁共振泌尿系水成像技术(MRU)在泌尿系统疾病检查 中的应用价值。方法:对20例(正常5例,输尿管结石8例,输尿管移行细胞癌1例,输尿管中下段狭窄、扭曲2例, 肾囊肿2例,肾透明细胞癌2例)泌尿系统疾病患者,均行IVU与MRU检查,并进行对比分析。结果:IVU和 MRU检查均能清晰显示输尿管的梗阻部位,定位正确率100%,而定性正确率MRU高于IVU,且对输尿管梗阻的 病变显示较佳,但MRU不能直接观察肾脏的分泌功能。结论:泌尿系统疾病患者应首选IVU检查,以观察其功能 和形态,而对输尿管有梗阻或肾脏有占位性病变的患者应选用MRU,对儿童及不能耐受IVU检查的患者MRU也 可作为首选。
Objective: To evaluate the technique value of MR urography (MRU) and intravenous urography (IVU). Methods: Twenty patients were examined using IVU and MRU. They were: normal(5), ureteral calculus(8), ureter transitional cell carcinoma(1), renal carcinoma(2), ureteral stricture(2) Results: MRU and IVU provided high resolution image of the urinary tract capable of determining the presence of 100%. MRU could be used to show ureteral obstruction, but not the struction of kidney. Conclusion: IVU was an efficient method for detecting urinary tract obstructive disorders, while MRU was more efficient for children and other patients who could not suffer from the examination of IVU.
