BLADDER-CANCER FOLLOWING ILEAL URETER

We report a case of squamous cell carcinoma of the ileovesical junctio n 12 years following total replacement of the ureter with ileum. The u roenteric junctions, which are not exposed to the fecal stream, may be associated with cancer as in ureterosigmoidostomy. The urine infected with fecal bacterial flora combined with a healing uroenteric suture line may be responsible for the tumorigenesis. Urine cytology should b e performed at least yearly beginning 10 years after ileal ureter. If any abnormality was suspected cystoscopy must be performed.
