A Case Report on Urothelial Carcinoma in the Ureteral Stump of a Nefrectomized Patient by Kidney Exclusion

Upper urinary tract urothelial carcinoma is a rare and possibly fatal disease. It sometimes affects the ureter, and it's even unusual in the ureteral stump of a patient who has had a nephrectomy for benign disease.The example of a male patient who underwent total left nephrectomy due to renal exclusion is described here. He was diagnosed with a urethral tumour of the ureteral stump after three years due to an episode of hematuria, and he had ureterectomy and bladder cuff excision. The ureteral stump being involved by a urothelial tumour is an incredibly rare occurrence that is usually linked with a poor prognosis due to the delay in detection caused by atypical presentation. Hematuria is the most prevalent symptom. Because there is no renal unit and hence no hydronephrosis, pain is uncommon.Although rare, primary tumours in the ureteral stump should be remembered, and a high level of diagnostic suspicion should be maintained to avoid diagnosis in the advanced stages. Our objective with this paper was to report a rare presentation of a urothelial carcinoma and to alert physicians.
