Congenital arteriovenous malformations of the genitourinary tract are rare. We report the first case of an arteriovenous malformation of the ureter. The patient presented with recurrent hematuria and left flank pain. Evaluation included an intravenous urogram, cystoscopy, and retrograde pyelography. A pedunculated lesion thought to be a fibroepithelial polyp was seen at the time of ureteroscopy, and the lesion treated by excisional biopsy and fulguration. Pathologic examination demonstrated an arteriovenous malformation. After thirty-month follow-up, the patient remains asymptomatic and free of recurrence.
先天性泌尿生殖道动静脉畸形较为罕见。我们报告首例输尿管动静脉畸形病例。该患者表现为反复血尿和左侧腰痛。评估包括静脉肾盂造影、膀胱镜检查和逆行肾盂造影。输尿管镜检查时发现一个带蒂病变，考虑为纤维上皮息肉，该病变通过切除活检和电灼治疗。病理检查显示为动静脉畸形。经过30个月的随访，患者仍无症状且未复发。
