Standard treatment for upper urinary tract urothelial carcinoma (UUTUC) implies the radical removal of all urothelium-lined tissue, which requires nephroureterectomy with bladder cuff removal. We report on a patient with a rare coincidence of UUTUC and horseshoe kidney in whom a preoperative angiography helped to identify and subsequently embolize an abberant isthmic feeding artery, which was located in between both collecting systems. Ischemic discoloration of the isthmus area facilitated resection and no major blood loss occurred. Preoperative superselective embolization of the isthmus as the renal split area can be an effective tool to facilitate nephroureterectomy in the case of a horseshoe kidney.
上尿路尿路上皮癌（UUTUC）的标准治疗方法包括根治性切除所有尿路上皮组织，这需要进行肾输尿管切除术和膀胱袖套切除。我们报告了一例 UUTUC 合并马蹄肾的罕见病例，术前血管造影有助于识别并随后栓塞异常的峡部供血动脉，该动脉位于两个集合系统之间。峡部区域的缺血性变色有助于切除，且没有发生大量失血。对于马蹄肾，术前峡部（即肾脏分裂区域）的超选择性栓塞可以作为辅助肾输尿管切除术的有效工具。
