N2 - We report two cases where gastrointestinal cancer gave rise to a metastatic ureteral tumor. Case one was a 64-year-old man who was operated on for descending colon cancer in September, 2007. In 2014, he was referred to our hospital because computed tomography (CT) scan showed a tumor of the right ureter. Ureteroscopic biopsy showed a metastatic ureteral tumor arising from descending colon cancer. The patient underwent open tumor resection. Transurethral resection of a bladder tumor (TUR- BT) was required three times for treatment of tumor recurrence from the ureteral stump in an effort to control gross hematuria Case two was a 62-year-old man who underwent pylorus-preserving gastrectomy for gastric cancer in December, 2014. Follow-up CT showed right hydronephrosis and thickening of the right ureteral wall in 2017. Selective urine cytology of the right ureter revealed urothelial carcinoma, class V. Ureteroscopic biopsy of the right ureter revealed invasive urothelial carcinoma. The patient underwent retroperitoneal laparoscopic nephroureterectomy. Histological examination revealed the right ureteral tumor to be metastasis of gastric cancer.
