Abstract

Sigmoidovesical fistula is a rare disease. Most of these patients have symptoms of chronic and recurrent urinary tract infection, pneumaturia and fecaluria. Furthermore, colorectal cancer with enterovesical fistula is very rare in the population. We have recently experienced a patient who had adenocarcinoma that originated colon along with sigmoidovesical fistula, and this was misdiagnosed as bladder cancer with urinary tract infection. We present here a case report of a 66-year-old woman who exhibited these diseases.
