A 49-year-old female was admitted with chief complaint of fecaluria on March 4th 1993. A radiation therapy had been performed for uterocervical cancer 18 years ago. The small intestine and bladder was detected by DIP- and cystogram simultaneously. It was diagnosed as an ileovesical fistula. A segmental resection of the ileum with partial cystectomy was performed on March 23rd. Histopathologically, the ileum showed a radiation enteritis. Eventually, we diagnosed that this ileovesical fistula was caused by radiation. After operation, an incompletion of suture occurred. So we made an ileostomy secondarily and performed hyperbaric oxygen therapy. The patient was getting well temporarily but died of gastric hemorrhage on May 1st.
