【摘要】 目的 提高下腔静脉后输尿管病的诊治水平。 方法 回顾性分析7例经手术证实的下腔静脉后输尿管,诊断主要依据静脉尿路造影 (IVU)、逆行尿路造影(RP)、B超及CT检查。结果 经IVU、RP、B超及CT检查,所有病例在术前均获得明确诊断;IVU显示5例上段输尿管扩张呈典型的反“J”状, 2例呈“锥形”改变;RP显示输尿管导管呈“S”形;CT扫描显示下腔静脉与腹主动脉间圆点状输尿管充盈影。结论 泌尿系造影检查是诊断下腔静脉后输尿管的可靠方法。

    【Abstract】 Objective To evaluate the diagnostic value and limitation of urography in retrocaval ureter.Methods 7 cases with retrocaval ureter confirmed by operation were retrospectively reviewed. Intravenous urography(IVU) and retrograde yelography (RP) were performed in all cases. Results All cases were definitely diagnosed by urography、ultrosonography and computed tomography before operation. On IVU, the dilation of the right pelvicalyceal system and upper ureter formed a characteristic reversed J-shape in 10 cases and tapering in 2 cases.On RP, the catheter presented S-shaped appearance. CT scan revealed opacification of ureter posterior to inferior vena cava, and scan at lower level revealed the ureter medial to vena cava and just anterior to vertebral body. Conclusion Urography is a reliable method for the diagnosis of retrocaval ureter. ......
