Late ureteral conduit urinary leak as a presentation of urothelial carcinoma of the ureter.

Urinary leakage at the ureteroenteric anastomosis in patients with urinary diversion is a rare complication that usually occurs in the early postoperative period, regardless of the indication for surgery. To our knowledge, ureteroenteric urinary leaks that occur late in the postoperative period have not been described. We present a unique case of a late ureteroenteric anastomotic leak within an ileal conduit that occurred as a result of recurrent urothelial carcinoma of the ureter at the site of anastomosis.
