A 58-year-old man was admitted to our hospital because of melena. He had undergone total cystectomy and ureterosigmoidostomy for bladder tumor 11 years before. We surmised the presence of a malignant tumor because of barium enema and colonofiberscopic findings, that showed a fungous tumor around the ureterosigmoidostomy. We, therefore, performed a sigmoidectomy and ureterostomy. Histological findings showed the tumor was a hyperplastic polyp without malignant cells. We report a rare case of hyperplastic polyp at the ureterosigmoid anastomosis occuring 11 years after total cystectomy and review the literature including our case.

Key words
total cystectomy, hyperplastic polyp after ureterosigmoidostomy
