CPT® Code 57310

A urethrovaginal fistula is a pathological connection between the urethra and the vagina, often resulting from surgical trauma during procedures such as anterior vaginal repair or from obstetrical trauma during vaginal delivery. The closure of this type of fistula, as described by CPT® Code 57310, involves a surgical procedure where the fistula is carefully exposed. The process begins with an incision of the vaginal mucosa, extending from the urethral meatus to the site of the fistula. This allows for the development and mobilization of fascial flaps on either side of the urethra, which are essential for the closure of the fistula. The surgical technique includes suturing the urethral mucosa to effectively close the fistula. Following this, the fascial flap on one side is sutured to the base of the flap on the opposite side, creating a secure closure. The procedure concludes with the closure of the vaginal mucosa, ensuring that the anatomical integrity is restored. This surgical intervention is critical for patients suffering from the complications associated with urethrovaginal fistulas, as it aims to restore normal function and alleviate symptoms associated with this condition.
