Abstract:

Vesicovaginal fistula (VVF), commonly caused by prolonged obstructed labor, is one of the worst complications of childbirth and poor obstetric care in the developing world. We investigated the clinical efficacy and outcome of technical modifications of the current transperitoneal supravesical technique for supratrigonal and complex vesicovaginal fistula. We studied a total of 20 patients with iatrogenic supratrigonal and complex vesicovaginal fistula following obstetric trauma and hysterectomy. All patients underwent a modified transabdominal technique: the modifications consisted of passing a Foley catheter through the fistulous opening, inflating the balloon, and applying traction on the catheter to provide effective anchorage and to minimize the oozing from the cystotomy edges. The cystotomy was directed in the parasagittal line, and medial side of the bladder was rotated as a flap into the bladder defect; the urethral de Pezzare catheter was used for urinary drainage. We used hemostatic matrix sealant (FloSeal, Baxter BioSurgery, Westlake Village, California) to promote healing and hemostasis. The vesicovaginal fistula was successfully corrected in all patients after the first attempt, and no significant bladder dysfunction or decrease in bladder capacity was seen after repair. Interposition flaps were used in all patients, and six patients (30%) required ancillary procedures for other associated anomalies at the time of fistula repair. At a mean follow-up of two years, fourteen women were sexually active, and 5 (35%) from this group of patients complained of mild-to-moderate dyspareunia. In our study, supratrigonal VVFs were repaired with a transabdominal, transperitoneal, transvesical approach. Tailoring the cystotomy in a parasagittal line permitted closure of fistula by rotation of bladder flap into the defect. This excellent method should be a viable option when repairing complex VVF.
