Successful endovascular treatment using a covered stent for artery–ureteral fistula after surgery for abdominal aortic aneurysm

摘要

Artery–ureteral fistula (AUF) is a rare condition but there is an increase in the number of reported cases. It is frequently difficult to treat. A 63-year-old male who had undergone a Dacron Y-graft placement for an infrarenal aortic aneurysm 3 years earlier, presented with hematuria. Contrast-enhanced computed tomography revealed a fistula located between the right common iliac artery and the right ureter at graft anastomosis. Endovascular treatment using a covered stent was performed successfully.Keywords: Artery–ureteral fistula, covered stent, endovascular treatment, ureteral obstruction
