Primary ureteral stump carcinoma: a rare entity following nephrectomy for non-malignant indications

Abstract

Primary ureteral stump carcinoma is an uncommon entity, developing after nephrectomy for non-malignant indications, and can pose a diagnostic challenge. We report a case of a 67-year-old male who presented with painless gross haematuria and burning micturition. The patient also had a history of right-sided nephrectomy, done ten years prior for chronic pyelonephritis. A contrast-enhanced computed tomography (CECT) scan showed an infiltrative soft tissue lesion at the proximal end of the residual ureteric stump, growing along its length. Ureteroscopy-guided biopsy confirmed the diagnosis of urothelial carcinoma. Due to the advanced stage of the disease, the patient was managed with neoadjuvant chemotherapy.
