【目的】总结下腔静脉后输尿管的诊治经验。【方法】对 6例下腔静脉后输尿管患者的症状 ,影像学检查和治疗进行回顾性分析。【结果】6例均有右腰胀痛 ,2例有发作性血尿 ,1例继发输尿管结石且伴肾绞痛发作。诊断主要依据IVU及逆行输尿管造影 ,表现为肾及输尿管上段积水 ,呈“S”形扩张。 6例均行狭窄段切除 ,输尿管复位成形术。随访 8个月至 12年 ,所有患者症状消失 ,肾积水明显减轻。【结论】对不明原因的右肾及右输尿管上段积水者应考虑到本病可能 ,IVU及逆行输尿管造影是主要诊断方法 ,狭窄段切除 ,输尿管复位成形术效果良好。
【Objective】 To summarize the diagnosis and treatment of ureter after inferior vena cava. 【Methods】 Six cases of inferior vena cava ureter patients with symptoms, imaging examination and treatment were retrospectively analyzed. 【Results】 All the patients had right lower quadrant pain, 2 had episodes of hematuria, 1 had secondary ureteral calculi with onset of renal colic. The diagnosis is mainly based on IVU and retrograde ureterography, showed as the upper kidney and ureter water, was “S” -shaped expansion. Six cases underwent stenosis resection, ureteral reduction and angioplasty. Follow-up 8 months to 12 years, all patients disappeared, hydronephrosis significantly reduced. 【Conclusion】 For the unexplained right kidney and upper right hydronephrosis of the right ureter should consider the possibility of this disease, IVU and retrograde ureterography is the main diagnostic method, stenosis resection, ureteral re-implantation is good.
