目的 提高下腔静脉后输尿管的诊治水平。方法 采用离断输尿管 ,在下腔静脉前外侧复位矫正方法 ,恢复输尿管正常通道。结果 1 0例术前均明确诊断 ,均经手术矫正复位。术后 6~ 1 2月复查 ,肾及输尿管上段扩张均明显减轻 ,肾功能良好 ,输尿管通畅 ,吻合口无狭窄。结论 下腔静脉后输尿管是先天性下腔静脉胚胎发育异常所致 ,术前需联合应用多种影像学检查明确诊断 ,输尿管离断复位矫正术是治疗下腔静脉后输尿管的主要方式
Objective To improve the diagnosis and treatment of ureter after inferior vena cava. Methods The ureter was cut off, and the anterolateral approach was used to correct the inferior vena cava to recover the normal ureter. Results 10 cases were diagnosed before surgery, were corrected by surgery. After 6 ~ 12 months review, renal and ureteral dilatation were significantly reduced, good renal function, ureteral patency, anastomotic stenosis. Conclusions The ureter of inferior vena cava is caused by the congenital inferior vena cava embryo dysplasia. It should be combined with various imaging examinations before operation to confirm the diagnosis. The ureteral reattachment and repositioning is the main way to treat the ureter after inferior vena cava
