 A 63-year-old man was referred to our hospital with the complaint of asymptomatic macroscopic hematuria. He had undergone right simple nephrectomy for renal stone and hydronephrosis caused by ureteral stone. Computed tomography(CT)and retrograde pyelography demonstrated a ureteral stump tumor and resection of the residual ureter was performed. The histological examination revealed grade 2 urothelial carcinoma without muscle invasion(pT1)and adjuvant chemotherapy was not performed. No remarkable recurrence or metastasis has been detected for 3 years after the operation. Ureteral stump tumor occurring after simple nephrectomy for benign kidney disease is relatively rare,however the morbidity rate is higher than common ureteral tumors. Owing post-operative observation after simple nephrectomy especially for infection or stone disease,long-term followup of ureteral stump should be considered.
