目的提高下腔静脉后输尿管病的诊治水平。方法报告２０例下腔静脉后输尿管。平均年龄３３．４岁。诊断主要依据静脉尿路造影及逆行输尿管肾盂造影。治疗以手术为主。除１例Ⅱ型（高襻型）未手术外，其余１９例Ⅰ型（低襻型）均行输尿管复位矫形术。切除下腔静脉后有病变的输尿管３～４ｃｍ，在无张力下进行输尿管吻合术，使输尿管恢复近于正常解剖部位的连续性。术后行Ｂ超和静脉尿路造影随访检查。结果肾积水都有不同程度改善，吻合口无狭窄。结论下腔静脉后输尿管复位矫形手术可获较好疗效。
Objective To improve the diagnosis and treatment of ureteral diseases after inferior vena cava. Methods 20 cases of inferior vena cava ureter were reported. The average age is 33.4 years old. Diagnosis is mainly based on intravenous urography and retrograde ureteroscopy. The main treatment is surgery. In addition to a case of type Ⅱ (high 襻 type) without surgery, the remaining 19 cases of type Ⅰ (low 襻 type) underwent ureteral reset orthosis. Removal of the inferior vena cava after the lesions of the ureter 3 ~ 4cm, ureter anastomosis without tension, the ureter to restore the continuity of the normal anatomic site. Postoperative B ultrasound and intravenous urography follow-up examination. Results Hydronephrosis has improved to varying degrees, anastomotic stenosis. Conclusion The retroperitoneal ureteral reposition orthopedic surgery can be a good effect.
