Digital subtraction iliac angiography displaying a short outpouch of contrast from the medial aspect of the proximal portion of the right external iliac artery. The close relationship to the ureter is displayed by the masked image of the stent. Then shown is selective engagement of the fistula orifice at the external iliac artery with ready passage of contrast across a short, irregular fistula to an otherwise normal appearing distal third of right ureter. Arterial stenting demonstrated in final image.
