Abstract
PUC is common in the urinary tract. It may occur in the urinary bladder and the collecting system of the upper urinary tract, such as the renal pelvis and ureter. However, PUC of ureteral stump after a nephrectomy is rare, and it’s even rarer in patients undergoing a radical nephrectomy for RCC. We describe a female patient with painless gross hematuria that was secondary to PUC of ureteral stump after a radical nephrectomy for RCC diagnosed 6 years ago. We discuss the etiology, diagnosis and treatment for PUC of ureteral stump following radical nephrectomy for RCC.
Highlights
A PUC of ureteral stump can be defined as a urothelial carcinoma occurring in the closed ureteral stump after a nephrectomy for either benign or malignant disease other than a urothelial carcinoma

Summary
A PUC of ureteral stump can be defined as a urothelial carcinoma occurring in the closed ureteral stump after a nephrectomy for either benign or malignant disease other than a urothelial carcinoma. The ipsilateral ureteral stump is usually left as short as possible due to the requirement of radical nephrectomy. The occurrence of malignant tumor of the ureteral stump following nephrectomy is extremely rare. The remaining ureteral stump does not receive routine examination during follow-up. K. et al [1] reported a male patient presented with microscopic hematuria during a routine checkup after undergoing a radical nephrectomy for RCC. The histologic diagnosis of the patient was transitional carcinoma of the ureteral stump.
