AB  - Acquired hydronephrosis following cystectomy and 
ileal conduit urinary diversion for bladder cancer is 
most commonly caused by stricture of the ureter or the 
ureteroenteric anastomosis. Nevertheless, malignant 
obstruction due to ureteral tumor recurrence must be ruled out. Neuroendocrine tumors of the ureter are 
extremely rare and an unlikely cause of hydronephrosis 
in this setting. We present the first reported case of a 
patient with a history of bladder cancer and an ileal 
conduit presenting with hydronephrosis secondary to an 
obstructing carcinoid tumor of the ureter.
