CPT® Code 57320

A vesicovaginal fistula (VVF) is a pathological condition characterized by an abnormal connection between the bladder and the vagina, resulting in the involuntary discharge of urine into the vaginal canal. The closure of this type of fistula is performed using a vaginal approach, as indicated by CPT® Code 57320. This surgical procedure aims to restore normal anatomy and function by effectively sealing the fistula, thereby preventing urine leakage. The procedure involves making a deep incision in the vaginal and perineal area to access the fistula tract. Once exposed, the fistula is catheterized to facilitate traction, allowing the surgeon to manipulate the fistula into the surgical field for better visibility and access. The surgical technique requires careful dissection and resection of the fistula tract, followed by the sequential closure of any defects in the bladder wall, fascia, and vaginal wall. This meticulous approach is essential to ensure a successful outcome and to minimize the risk of complications associated with the repair of vesicovaginal fistulas.
