Villous Adenoma of Ureteral Stump: An Unusual Presentation of Ureteral Stump Syndrome

Abstract

Ureteral stump syndrome (USS) is a rare condition occurring after nephrectomy due to residual ureteral pathology, including reflux, infection, calculi, empyema, or malignancy. A long ureteral stump may predispose patients to USS by promoting urine stasis. Ureterocutaneous fistula, a rare complication, requires accurate diagnosis to avoid unnecessary treatment. Management involves identification of cause and corrective measures including surgical excision. Malignant transformation, though rare, underscores the need for thorough pre-treatment assessment. A multidisciplinary approach integrating clinical, radiological, and microbiological evidence is essential for effective diagnosis. We hereby present a first case of villous adenoma of ureteral stump.
