Introduction Pelvic arteriovenous malformation is often a source of intraoperative bleeding. Here, we report our experience with a case of ureteral cancer with pelvic arteriovenous malformation treated using laparoscopic nephroureterectomy with temporary intraoperative occlusion of the internal iliac artery. Case presentation A 75‐year‐old man presented to our hospital with asymptomatic macro‐hematuria. Contrast‐enhanced computed tomography revealed right ureteral tumor with no apparent metastases, and right pelvic arteriovenous malformation. Three months later, multiple bladder cancers were identified and the patient underwent trans‐urethral resection of bladder tumor. The pathological diagnosis was urothelial carcinoma, pTa. We performed right laparoscopic nephroureterectomy with temporary intraoperative occlusion of the internal iliac artery. There was little intraoperative bleeding, and the surgery was safely completed. The pathological diagnosis was urothelial carcinoma, pT2 + Tis. Conclusion A patient showing ureteral cancer with pelvic arteriovenous malformation was safely treated using laparoscopic nephroureterectomy with temporary occlusion of the internal iliac artery.
