[Ileovesical fistula caused by long-term indwelling of urethral catheter: a case report].

A case of an ileovesical fistula is reported. The patient was a 32-year-old female who suffered from spina bifida. She had had a urethral catheter indwelt at 13 years old for continuous incontinence caused by atrophic bladder. The patient noted lower abdominal discomfort and fecal urine at age 31 in January, 1989 and urination from anal appeared in March, 1990. In November, 1990, the patient was introduced to our hospital and diagnosed with ileovesical fistula. We performed partial cystectomy, ileal wedge resection and cystostomy on this patient. The pathological findings showed chronic inflammatory change. The ileovesical fistula may have been caused by a long-term indwelling of urethral catheter. We discussed the ileovesical fistula and the treatment of neurogenic bladder in a patient of spina bifida.
