vesicovaginal fistula
Pronunciation: VES-ih-ko-VAJ-ih-nal FIS-tu-lah
An abnormal connection between the bladder and vagina that allows urine to leak into the vaginal canal.
Full Definition
A vesicovaginal fistula is an abnormal epithelialized tract that connects the bladder to the vagina, resulting in continuous urinary leakage through the vaginal canal. This condition most commonly occurs as a complication of gynecologic surgery, particularly hysterectomy, but can also result from radiation therapy, malignancy, or obstetric trauma. Patients typically present with continuous urinary incontinence and may develop recurrent urinary tract infections. Diagnosis is confirmed through cystoscopy, intravenous pyelography, or specialized dye tests. Treatment usually requires surgical repair, which may be approached transvaginally or transabdominally depending on the size and location of the fistula.
Usage
Usage note: Often abbreviated as VVF in clinical notes; distinguish from other types of genitourinary fistulas.
