Ureteroarterial fistula (UAF) is an uncommon condition with only approximately 150 cases reported in the literature. Patients typically present with hematuria in the setting of prolonged ureteral stenting, prior pelvic surgery, malignancy, or radiation. Presentation can vary from intermittent hematuria to life-threatening hemorrhagic shock.
Recognizing this condition in a prototypical patient is essential for accurate diagnosis and management. Angiography yields the highest diagnostic benefit, and arterial stent-graft placement is the treatment of choice.
输尿管-动脉瘘（UAF）是一种罕见的病症，文献中仅有约 150 例报告。患者通常在长时间留置输尿管支架、先前的盆腔手术、恶性肿瘤或放疗后出现血尿。表现形式从间歇性血尿到危及生命的出血性休克不等。
在典型患者中识别这种情况对于准确诊断和治疗至关重要。血管造影可提供最高的诊断收益，动脉支架置入是首选的治疗方法。
