Ureter-arterial fistula (UAF) is an uncommon condition. The presentation is usually a life-threatening intermittent massive gross hematuria and the diagnosis is still a challenge for urologist. Idiopathic Retroperitoneal fibrosis (IRF) is a condition of unknown etiology characterized by a highly fibrotic retroperitoneal mass that frequently causes ureteral obstruction. To our knowledge we report the first case describing the UAF in a patient suffering from IRF. We hypothesize that inflammation and fibrosis resulted in fixation of the ureter to the adjacent artery causing a fistulous path. UAF was managed by deploying a 10 x 59 mm endo-graft at the intersection of common iliac artery bifurcation with the right ureter. Post treatment course was uneventful.
输尿管-动脉瘘（UAF）是一种不常见的疾病。其表现通常为危及生命的间歇性大量肉眼血尿，诊断仍然是泌尿科医生面临的挑战。特发性腹膜后纤维化（IRF）是一种病因不明的疾病，其特征为高度纤维化的腹膜后肿块，常导致输尿管梗阻。据我们所知，我们报告了首例患有 IRF 的患者出现 UAF 的病例。我们假设炎症和纤维化导致输尿管固定在相邻动脉上，从而形成瘘管。UAF 通过在髂总动脉分叉处与右侧输尿管交汇处放置 10 x 59 mm 的内移植物来治疗。治疗后过程顺利。
