Small Bowel Adenocarcinoma of Ileal Ureter 40 Years After Ureteral Reconstructive Surgery.

Malignant neoplasm arising from ileal ureter used for ureteral reconstructive surgery is an exceedingly rare event. Ureteroileoplasty was being performed since the beginning of the last century, but it was described more extensively in literature during the 1950s.1,2 Recurrent urinary infections, chronic renal failure, urolithiasis, anastomotic stricture, metabolic acidosis, and chronic dilation of the graft had been described as late complications of ureteroileoplasty.3,4 Herein, we describe history, imaging and pathologic findings of a small bowel adenocarcinoma arising from ileal ureter in a woman of 78-year-old, subjected to ureteroileoplasty about 40 years earlier.
