Endovascular removal of a misplaced ureteral stent in the vena cava: a complication of ultrasound-guided percutaneous nephrolithotomy.

Intravascular migration of a double J stent into the inferior vena cava is an uncommon complication. Active prevention, timely diagnosis, and early intervention are crucial for this complication. Intravascular interventional therapy is relatively easy, less traumatic, and has a high success rate. It can be used to select patients for intravascular ectopic DJS treatment.
