下腔静脉后输尿管21例临床分析

Clinical analysis of 21 cases of retrocaval ureter

目的 :提高下腔静脉后输尿管的诊治水平。方法 :联合运用相关影像学检查明确诊断。治疗上采用离断输尿管 ,于下腔静脉前外侧复位矫正 ,恢复输尿管正常通道。结果 :2 1例术前均明确诊断并予以分型 ,均经手术矫正复位。术后 6～ 12个月复查 ,肾及输尿管上段积水扩张均明显减轻 ,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 ,需联合应用各种影像学检查明确诊断。

Purpose:To evaluate the diagnosis and treatment of retrocaval ureter.Methods:The combination of several image methods was used to make the diagnoses. Operation is the the treatment of choice for retrocaval ureter, we dismembered the ureter and anastomosed it anterolaterally which will rehabilitate the ureter in front of the inferior vena cava.Results:Diagnosis was confirmed in all 21 cases before the operation. All cases underwent successful operation. The patients have been followed up for 6~12 months without stenosis. Hydronephrosis was relieved with good renal function.Conclusions:Retrocaval ureter is caused by the abnormal development of inferior vena cava in the embryonic phase. Diagnosis depends on the combination of several image methods. Dismembered Ureteroplasty is the main operative procedure for the treatment of retrocaval ureter.
