Imaging of vesicovaginal fistula using volume rendering technique by 16-Slice multidetector CT

Vesicovaginal fistula (VVF) is a communication between the posterior wall of urinary bladder and the vagina. VVF occurs most frequently, post hysterectomy, during obstructed labour and post radiation mainly for carcinoma cervix. Computed tomographic (CT) cystography has the distinct advantage of precisely demonstrating the communication between urinary bladder and the genital tract. For a successful repair and prevention of recurrence accurate diagnostic evaluation and timely repair with interposition flaps is mandatory
