Abstract

A malignant tumor developing from a residual ureteric stump after a nephrectomy for benign disease is extremely rare. We report a 78-year-old woman with a high-grade invasive ureteral carcinoma that arose in the ureteral stump 25 years after an ipsilateral nephrectomy for benign pathology. Urologists should keep this pathology in mind in the differential diagnosis of hematuria.
