Ureteroarterial fistula embolization by transradial approach: A case report

Ureteroarterial fistula is a rare condition wherein a communication develops between a ureter and the common, internal, or external iliac artery. Localizing the fistula can be difficult, as cystoscopy, CT angiography, and conventional angiography have low sensitivity in identifying the fistula. Provocative maneuvers within the ureter, however, can aid in the visualization of fistulae on angiography. Prior reports of endovascular repair have utilized transfemoral access, which makes performing concurrent provocative maneuvers in the ureter challenging. We present a case of successful endovascular ureteroarterial fistula localization and embolization in an 80-year-old woman with recurrent gross hematuria by the transradial approach, aided by concurrent provocative maneuvers performed via cystoscopy. The transradial endovascular approach facilitated a multi-disciplinary joint procedure that resulted in effective treatment of the patient.
