A double J stent (DJS) is the main therapy for ureteral obstruction when conservative treatment fails. Antegrade migration in the bladder - or retrograde migration in the ureter - are well-known complications. We present a case with intravascular migration of a DJS into the inferior vena cava. Inferior venocavagraphy confirmed the position of the stent, and thrombus formation was excluded at its tip. The stent was retracted endoscopically. After the procedure, limited contrast leakage was seen at the perforation site on venography. The current available literature is reviewed. Based on this, a management algorithm is drawn up.
双J管（DJS）是保守治疗失败后输尿管梗阻的主要治疗方法。膀胱内顺行迁移或输尿管内逆行迁移是众所周知的并发症。我们报告一例双J管血管内迁移至下腔静脉的病例。下腔静脉造影证实了支架的位置，并排除了其尖端血栓形成。通过内镜将支架取出。术后，静脉造影显示穿孔部位有少量造影剂渗漏。本文回顾了现有的文献，并据此制定了处理流程。
