[Metastasizing adenocarcinoma of the colon in a patient with ceco-cystoplasty].

Augmentation and substitution erocystoplastias are currently widely accepted techniques for the treatment of several benign and malignant diseases. Appearance of neoplasia on the various gut segments used after a latency period ranging from 5 to 25 years following initial surgery has been described. The paper presents one case of metastatic colon adenocarcinoma initially located in the region of ureteral reimplantation, in a patient with augmentation cecocystoplastia performed as a result of vesical retraction secondary to genitourinary tuberculosis. Appearance of this type of neoplasia in an increasing population, quite often young, compels the urologist to keep a tight watch. Endoscopic monitoring of the new bladder is the most effective diagnostic procedure. A once-a-year endoscopy after an interval as yet not definitely established, but which could be around 10 years after initial enterocystoplastia, seems advisable at least in cases at higher risk.
