“…Previous studies have reported that the immediate success rate of EVT using stent-graft or metallic stents was 85%-100% (Fox et al 2011;Okada et al 2013). However, the hematuria recurrence-free rates at 1 and 2 years were 76.2% and 40.6%, respectively (Okada et al 2013). The mechanism of this high recurrence rate appears to be the ongoing process of inflammation and advancement of malignancy.…”

Background: Ureteroarterial fistula is a rare life-threatening complication of indwelling ureteral stents. The mechanism has not yet been fully evaluated using intravascular imaging. Case presentation: An-84-year-old female was referred to our unit because of large volume pulsatile bleeding from the left ureter during routine stent exchange in the urology department. The hematuria was initially managed by rapidly exchanging for a new stent; however, the patient went into hypovolemic shock due to acute blood loss. The patient underwent implantation of the bilateral ureteral stents due to urinary retention caused by retroperitoneal fibrosis 2 years ago. To prevent ureteral infection, occlusion of the stents and stone formation, the stents were exchanged every 6 months. Computed tomography revealed contact between the left ureter and the common iliac artery. Therefore, ureteroarterial fistula was suspected and endovascular therapy was performed. Although angiography did not show definite blood flow into the ureter, a soft guidewire was advanced from the subintima of the external iliac artery to the left ureter. The diagnosis of ureteroarterial fistula was confirmed. Intravascular ultrasound identified the stent in the ureter and its connection to the subintima of the external iliac artery. The ureter did not contact directly to the inner lumen of the iliac arteries according to the ultrasound findings; therefore, we considered that the risk of stent-graft infection might not be high. After coil embolization of the ipsilateral internal iliac artery, a covered stent was implanted in the external iliac artery to seal the subintimal entry. The patient had no further episodes of any gross hematuria on dual anti-platelet therapy, when the ureteral stent was exchanged three time during 1 year after the endovascular therapy. Conclusions: We demonstrated a case of ureteroarterial fistula, in which intravascular ultrasound allowed to visualize the communication between the ureter and the subintimal lumen in the external iliac artery.

“…Instead, endovascular stent engraftment is a safe and effective method for managing acute events; however, the rate of hematuria recurrence remains high with this technique, and additional procedures or reconstructive surgery may be needed. 11 The two patients in our cohort who had received a stent graft finally underwent bypass surgery 6 to 8 months after receiving this engraftment.…”

“…Although endovascular treatment using a covered stent has some disadvantages, such as not dealing with fistula formation, severe complications such as stent occlusion or stent graft infection are very rare. [ 4 5 ] Additional cases and longer follow-ups are likely to demonstrate the further utility of endovascular procedures with covered stents.…”

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

2015

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.

Long-term Results of Endovascular Stent Graft Placement of Ureteroarterial Fistula

Abstract: Endovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.
