Intravascular migration of a double J stent into the inferior vena cava is an uncommon complication. The management of such complication is less reported in the literature. This study aimed to reveal the diagnosis and treatment process of migration of a double J stent into the inferior vena cava. A 53-year-old male patients was transferred to our hospital because of migration of a double J stent into the inferior vena cava after left-side pyelolithotomy. In accordance with manifestations on computed tomography urography, the patient was diagnosed with migration of a double J stent into the inferior vena cava. Percutaneous nephroscope under C-arm guidance was performed to remove the migrated stent. After the operation, the patient was treated with continued anticoagulants and antibiotics. The migrated stent was removed successfully without any complications, and a new double J stent was placed and its location was confirmed under C-arm. The patient was discharged in good condition and the follow-up was uneventful. Intravascular migration of a double J stent into the inferior vena cava is an uncommon complication. Radiologic imaging after placement of ureteral stent is critical for prevention of this complication. Percutaneous nephroscope under C-arm guidance is a safe and effective approach to remove the migrated DJS in the IVC.
