title: [Ileovesical fistula caused by bladder cancer with bladder stone].
abstract: Enterovesical fistula is a very rare complication of primary urological malignancies. A case of ileovesical fistula caused by a bladder carcinoma is presented. A 66-year-old male was referred with complaints of urinary pain. On admission, fecaluria and urinary tract infection with bladder stone were detected. Cystography revealed the passage of contrast medium into the small bowel. Under the diagnosis ofileovesical fistula due to suspected inflammatory disease, sigmoidectomy and segmental small bowel resection with partial cystectomy were performed. Histological evaluation revealed a poorly differentiated urothelial carcinoma. Without further treatment, the patient died from cancer five months after operation. However, it is hard to assess the effect of fistulas on prognosis. Since it has been reported that about 40% of the patients with T4 bladder tumors could be potentially cured with radical resection, we recommend a thorough examination to confirm the diagnosis of primary disease to obtain the best results.
