[Morphological changes of Kock pouch investigated by autopsy two years nine months postoperatively].
A 62-year-old male patient consulted us because of gross hematuria and was diagnosed as having a bladder tumor. Total cystectomy was performed and a Koch pouch was utilized. Two years and nine months later, he died as a result of recurrence of bladder tumor and pathological autopsy was performed. A microscopic section of the reservoir mucosa showed a reduction in the number of crypts and an increase in the number of goblet cells. These morphological changes seemed to be caused by chronic exposure to urine, but have a favorable effect upon metabolic alterations following the utilization of the Kock pouch.
