Official Description

Closure of urethrovaginal fistula; with bulbocavernosus transplant

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A urethrovaginal fistula is a pathological connection between the urethra and the vagina, which can lead to significant complications such as urinary incontinence and recurrent urinary tract infections. This condition often arises as a result of surgical trauma during procedures like anterior vaginal repair or can occur due to obstetrical trauma during vaginal delivery. The closure of a urethrovaginal fistula, specifically with the use of a bulbocavernosus transplant, is a surgical procedure aimed at repairing this abnormal connection. The procedure involves not only the closure of the fistula but also the incorporation of a muscle flap from the bulbocavernosus muscle to enhance blood supply to the affected area, which may have suffered damage from prior surgical interventions or radiation therapy. This dual approach helps to ensure a more robust healing process and reduces the risk of recurrence of the fistula. The surgical technique requires careful dissection and mobilization of tissues to achieve a successful repair while minimizing complications and promoting optimal recovery for the patient.

1. Indications

The closure of a urethrovaginal fistula with a bulbocavernosus transplant is indicated in the following situations:

  • Urethrovaginal Fistula A pathological connection between the urethra and vagina, often resulting from surgical trauma or obstetrical complications.
  • Previous Surgical Trauma Patients who have undergone anterior vaginal repair or other pelvic surgeries that may have led to the development of a fistula.
  • Obstetrical Trauma Women who have experienced trauma during vaginal delivery that has resulted in a fistula.
  • Compromised Tissue Vascularization Cases where the surrounding tissues have been damaged by prior surgical procedures or radiation, necessitating the use of a muscle flap for improved blood supply during repair.

2. Procedure

The procedure for closing a urethrovaginal fistula with a bulbocavernosus transplant involves several detailed steps:

  • Step 1: Exposure of the Fistula The surgeon begins by exposing the urethrovaginal fistula. This is typically done by incising the vaginal mucosa from the urethral meatus to the site of the fistula. This incision allows for direct access to the fistula for repair.
  • Step 2: Development of Fascial Flaps Once the fistula is exposed, fascial flaps are developed and mobilized on each side of the urethra. These flaps are essential for providing the necessary tissue to close the fistula effectively.
  • Step 3: Closure of the Fistula The fistula is then closed by suturing the urethral mucosa. The fascial flap on one side is sutured to the base of the flap on the opposite side, creating a secure closure of the fistula.
  • Step 4: Double-Breasted Closure The flap on the opposite side is closed over the first flap in a double-breasted fashion, ensuring that the closure is robust and minimizes the risk of recurrence.
  • Step 5: Mobilization of Bulbocavernosus Muscle The labia majora is incised to allow for the mobilization of the bulbocavernosus muscle and fat pad. This muscle is critical for providing vascularization to the repaired area.
  • Step 6: Tunneling of the Muscle The bulbocavernosus muscle is transected and tunneled under the vaginal mucosa, labia minora, and labia majora. This step is crucial for positioning the muscle flap over the repaired fistula.
  • Step 7: Suturing the Muscle Flap The muscle flap is then sutured over the repaired fistula, providing additional support and vascularization to the area.
  • Step 8: Closure of the Fascia The fascia is closed over the muscle flap in a double-breasted fashion, further securing the repair.
  • Step 9: Repair of Labia and Vaginal Mucosa Finally, the labia majora and vaginal mucosa are repaired to complete the procedure.
  • Step 10: Placement of Suprapubic Catheter A suprapubic catheter is placed to allow the urethra to heal properly, ensuring that urine is diverted away from the surgical site during the recovery period.

3. Post-Procedure

After the procedure, patients can expect a recovery period that may involve monitoring for any signs of complications such as infection or recurrence of the fistula. The placement of a suprapubic catheter allows for the urethra to heal without direct pressure or irritation from urine flow. Patients will be advised on care for the surgical site, including hygiene practices and activity restrictions to promote healing. Follow-up appointments will be necessary to assess the success of the repair and to remove the catheter once healing is confirmed.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
