A case of long ureteral polyp with ureteropelvic junction obstruction in a 29-year-old man is reported. He had complained of occasional left flank pain since several years earlier. Excretory urography showed left giant hydronephrosis and no urolithiasis. Retrograde pyelography revealed a mass lesion of the left upper ureter. At exploration, the left ureteropelvic junction was found to be obstructed by an aberrant lower pole renal vessel. At just distal of the junction, a finger-like ureteral polyp, 5 cm in maximal length, was present and accompanied with several little polyps. Partial ureterectomy and pyeloplasty improved the left hydronephrosis. The patient remains symptomless for one year after the operation.
报告了一例29岁男性长输尿管息肉伴肾盂输尿管连接处梗阻的病例。他自几年前起就偶尔抱怨左腰部疼痛。排泄性尿路造影显示左肾巨大积水且无尿路结石。逆行肾盂造影显示左输尿管上段有一肿块病变。手术探查时发现肾盂输尿管连接处被一根异常的下极肾血管阻塞。在连接处稍远的部位，有一个指状输尿管息肉，最长达5厘米，并伴有几个小息肉。部分输尿管切除术和肾盂成形术改善了左肾积水。患者术后一年无症状。
