摘要
目的:探讨磁共振泌尿系造影(MRU)在尿路梗阻中的诊断价值。材料与方法:对53例尿路梗阻者的MRU检查表现与手术和病理结果对照分析。结果:53例尿路梗阻患者中,先天性输尿管狭窄29例,输尿管结石8例,输尿管良性狭窄7例,输尿管癌5例,膀胱癌侵及输尿管4例,所有病例MRU均能确定梗阻水平并且清晰显示梗阻端形态和特征。结论:MRU是尿路梗阻无创、安全的检查方法,具有可靠的诊断价值,尤其对造影剂过敏或不显影、重度肾积水患者更为适用。
Purpose: To evaluate the diagnostic value of magnetic resonance urography (MRU). Materials and Methods: 53 patients with urinary obstruction were perfomed MRU. Their image findings were analyzed and correlated with the surgical and pathological findings. Results; In 53 cases with urinary tract obstructive, there were: congenital ureteral stricture (29) , calculus (8) , benign stricture (7) , ureteral carcinoma (5), bladder disorder (4). MRU of all the patients documented the siteN shape and features of urinary obstruction. Conclusion: MRU is a noninvasive, safe and effective method in the diagnosis of urinary obstruction, particularly for the patients with allergic to iodine or non - visualisation or severe hydronephrosis on intravenous urogram.
