磁共振尿路造影在临床泌尿道梗阻中的诊断价值

目的：评估磁共振尿路造影在临床泌尿道梗阻中的诊断价值。方法：回顾性对61例例泌尿系统梗阻患者的的MRU检查所见与手术和病理结果对照分析。结果：61例泌尿系梗阻患者，输尿管癌7例，输尿管结石8例，下腔静脉后输尿管1例，输尿管良性狭窄11例，先天性输尿管狭窄27例，膀胱癌侵及输尿管4例，泌尿系改道手术后再次发生良性梗阻患者3例，所有病例MRU均确定梗阻水平并且清晰显示梗阻端形态和特征。结论：NMR是一种安全、可靠、无创的检查方法，尤对IVU不显影或仅显示扩张的肾盏、肾孟影的重度肾积水病例或对比剂过敏的患者更有诊断价值。

Diagnostic value of MR urography in urinary tract obstruction

Objective:To assess the diagnostic value of MR urography (MRU) in urinary obstruction.Methods:Sixty-one patients with urinary obstruction were performed MRU.Their image findings were retrospectively analyzed and correlated with the surgical and pathological findings.Results:61 cases of urinary obstruction included ureteral carcinoma in 7,ureteral calculus in 8,retrocaval ureter in 1,benign ureteral stricture in 11,congenital ureteral stricture in 27,invasion of ureter from bladder carcinoma in 4,recurrent benign ureteral obstructure after operation of urinary diversion in 3.MRU of all the patients documented the site,shape and features of urinary obstruction.Conclusion:MRU is a safe,noninvasive and effective method in the diagnosis of urinary obstruction,particularly for the patients with non-visualisation or severe hydronephrosis on intravenous urogram or patients allergic to iodine.
