摘　　要：目的:探讨电视透视下局部加压法静脉尿路造影在尿路梗阻性病变诊断中的应用价值。方法:76例临床和病理诊断尿路梗阻性病变患者(泌尿系结石42例,肾盂旁囊肿15例,输尿管癌及肾盂癌5例,先天或后天性输尿管狭窄14例),电视透视下行常规静脉尿路造影和局部加压静脉尿路造影。两位高年主治医师对常规造影图像与局部加压法图像评判图像质量并分为3级:0级,不能进行定性、定位诊断;Ⅰ级,可定位分析,不能定性分析;Ⅱ级,能进行定位、定性分析。结果:电视透视下常规静脉尿路造影梗阻部位定位诊断符合率71.1%,定性诊断符合率19.7%;局部加压法静脉尿路造影梗阻部位定位诊断符合率93.4%,定性诊断符合率64.5%,局部加压法静脉尿路造影中图像质量优于常规尿路造影(P<0.01)。结论:电视透视下静脉尿路造影结合梗阻区局部加压,局部放大摄影有助于更好显示梗阻部位及定性诊断,其诊断价值明显优于常规静脉尿路造影。Objective：To discuss the value of pressure magification IVU （intravenous urography） under x--ray fluoros copy in the diagnosis of urinary obstructions. Methods：76 patients with urinary obstruction confirmed by clinic and pathology （42 urinary calculi, 15 parapelvic cysts, 5 primary ureteral ceircmoma and renal pelvic carcinoma, 14 congential or acquired ureter stenosis） underwent the general IVU and the pressure magification IVU under X ray fluoroscopy. The diag nostic values of them were classified into 3 grades by two physicians：Grade 0, no diagnostic value;Grade 1, localization of the lesion was possible;Grade 2, both localization and characterization was possible. Results：The accuracy of the location diagnosis examed by the general IVU was 71.1 % and diagnostic rate of the obstructive etiology was 19.7%. The accuracy of the location diagnosis examed by the pressure magification IVU was 93.4 % and diagnostic rate of the obstructive etiology was 64.5%. The pressure magification IVP was superior to the general IVU in both localization and qualitative diagnosis for urinary obstructions （P〈0.01）. Conclusion：The pressure magification IVU under X ray fluoroscopy is easier to detecte the obstructed sites and qualitative diagnosis,and it is superior to the general IVU.
