Abstract:
A 70-year-old man with previous history of TUR-BT presented positive urinary cytology at one year follow-up. Cystoscopy with bladder mapping was negative, and IVP revealed multiple outpouchings of the right upper ureter without hydronephrosis. Ureteroscopy failed because of an underlying stricture. Surgical excision of the strictured segment and of 2.5 cm of cranial ureter was performed. Histopathology demonstrated focal hyperplasia of the urothelium with outpouchings involving only the mucosa, compatible with the diagnosis of pseudodiverticula.
