1 Evolution from open surgical to endovascular treatment of ureteral-iliac artery fistula 
Rafael D. Malgor, MD, Gustavo S. Oderich, MD, James C. Andrews, MD, Michael McKusick, MD, Manju Kalra, MBBS, Sanjay Misra, MD, Peter Gloviczki, MD, Thomas C. Bower, MD  Journal of Vascular Surgery  Volume 55, Issue 4, Pages (April 2012) DOI: /j.jvs Copyright © Terms and Conditions

2 Fig 1 Technique of endovascular treatment of ureteral-iliac artery fistula (UIAF). Right iliac angiography reveals no obvious extravasation of contrast in the crossing point of the ureteral stent (A, black arrow), but selective catheterization of the fistulous communication demonstrates contrast extravasation into the right ureter and ureteral stent (B, black arrow). The patient was treated with covered balloon-expandable stent (C), which was deployed in the external iliac artery (D, black arrow) preserving flow into the internal iliac artery.

3 Fig 2 Patient with complex ureteral-iliac artery fistula (UIAF) with erosion into the rectum presented with massive hematuria and exsanguinating hemorrhage 3 months after endovascular treatment by self-expandable stent graft at other institution. Left iliac angiography (A) demonstrates disruption of the left iliac artery and stent graft with extravasation of contrast into the retroperitoneum. A catheter was used to traverse the disrupted stent (A, black arrow). The patient was treated by placement of a self-expandable stent graft (B) as a bridge to definitive repair. Contrast enema (C) also confirmed communication of the rectum with the complex abscess in the retroperitoneum space. The patient subsequently underwent staged right-to-left femoral crossover bypass, followed by abdominal exploration, resection of the left external iliac artery, ureteral conduit, colectomy, and colostomy.
