Transurethral coil embolization for the management of ureteroarterial fistula: a case report

A 71-year-old woman who had undergone a total abdominal hysterectomy and pelvic irradiation for cervical cancer and fecal diversion for adhesive ileus was referred to us for a "left" ureteral stone and intermittent gross hematuria. Bilateral ureteral stents had been indwelled because of lower ureteral strictures for a long time. Hematuria continued after the removal of the ureteral stone, and she once went into hypovolemic shock at the time of exchange of the right ureteral catheter. Selective arteriography revealed a "right" ueteroarterial fistula. Endovascular management alone failed to resolve the fistula, but a subsequent transurethral metal coil embolization was effective, and the hematuria was relieved. She is still free from disease at 7-month followup. As far as we know, there has been no previous report of a transurethrally managed ureteroarterial fistula.
