Abstract
BACKGROUND: Ureteral arterial fistula is a rare and challenging clinical entity. The diagnosis and management of ureteral arterial fistula present a unique disease process that requires a dual specialty approach, involving both vascular and urologic surgeons. There are different options for repair, including both open and endovascular techniques. METHODS AND RESULTS: A 78-year-old male presented to the emergency department (ED) in septic shock secondary to a urinary tract infection and was admitted to the intensive care unit (ICU) for further management and resuscitation. The patient had previously undergone radical cystoprostatectomy with ileal conduit creation in 2011 for recurrent bladder cancer. Following creation of his ileal conduit, he required long-term indwelling ureteral stents bilaterally due to recurrent stricturing at the ureteroneocystostomy with stent exchanges performed 2-3 times per year due to frequent urinary tract infections. During his hospitalization for sepsis, the urology service performed an exchange of his left indwelling ureteral stent. However, pulsatile bleeding was observed from the junction of the ileal conduit and left ureter. The stent was replaced at the bedside, and the bleeding ceased. Vascular surgery consultation and a computed tomography angiogram (CTA) gave support to the diagnosis of a ureteral arterial fistula. A plan was developed to exchange the stent in the operating room with vascular surgery assistance. It was determined that a definitive open repair with excision of the fistula would be the most appropriate course. CONCLUSIONS: In the setting of hemodynamically significant bleeding, we recommend an endovascular approach to obtain hemostasis. However, an open approach provides both reconstruction and infectious resistance in an already soiled field. Open repair may provide a more definitive reconstruction. Published by Elsevier Inc.
