A case of ileosigmoidovesical fistula due to sigmoid colon diverticulitis

Abstract

The patient was a 65–year–old man who had had recurrent bouts of polyuria, turbid urine and dysuria, despite treatments with medication under the diagnosis of acute prostatitis at the department of urology in our hospital for these several years. In March 2007 he visited the urological department because of the same symptoms. Urine culture yielded Escherichia coli, and the patient was diagnosed as having vesicosigmoidal fistula due to sigmoid colon diverticulitis by colonoscopy and abdominal CT scan, and then he was referred to our department of surgery. Contrast enema study revealed ileosigmoidovesical fistula. Resection of the sigmoid colon, part of the ileum and the rectum were perfomed along with colostomy in May of the year. Ileosigmoidovesical fistula due to sigmoid colon diverticulitis is very rare.
