Official Description

Closure of rectourethral fistula;

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A rectourethral fistula is defined as an abnormal connection or passage that forms between the rectum and the urethra. This condition can arise due to various factors, including postoperative complications, chronic infections, inflammation of the bowel, malignant tumors, or trauma. The presence of such a fistula can lead to significant clinical issues, including incontinence and recurrent urinary tract infections. The closure of a rectourethral fistula is a surgical procedure aimed at repairing this abnormal communication, thereby restoring normal function and preventing further complications. There are multiple surgical approaches to address this condition, including abdominal, perineal, and para sacrococcygeal (trans-sphincteric) techniques. Prior to the surgical intervention, a suprapubic cystostomy may be performed to divert urine temporarily from the urethra, or a catheter may be placed in the urethra to facilitate the procedure. The surgical technique involves careful dissection and closure of the fistula, ensuring that both the rectal and urethral openings are properly addressed to promote healing and restore anatomical integrity.

1. Indications

The closure of a rectourethral fistula is indicated in the following situations:

  • Postoperative Complications - The procedure is often necessary when a fistula develops as a complication following surgical interventions in the pelvic region.
  • Chronic Infection - Patients suffering from chronic infections that lead to the formation of a fistula between the rectum and urethra may require this surgical closure.
  • Inflammation of Bowel - Inflammatory conditions affecting the bowel can result in the development of a rectourethral fistula, necessitating surgical intervention.
  • Malignant Neoplasm - The presence of tumors in the pelvic area can contribute to the formation of fistulas, which may require closure to alleviate symptoms and prevent further complications.
  • Trauma - Traumatic injuries to the pelvic region can also lead to the creation of a rectourethral fistula, making surgical closure essential for recovery.

2. Procedure

The procedure for the closure of a rectourethral fistula involves several critical steps, which may vary depending on the surgical approach chosen by the physician.

  • Step 1: Preparation - Prior to the surgical procedure, a suprapubic cystostomy may be performed to divert urine from the urethra temporarily. Alternatively, a catheter may be placed in the urethra to facilitate the procedure.
  • Step 2: Incision - Using a trans-sphincteric approach, a curvilinear incision is made between the coccyx and the posterior margin of the anus. This incision allows access to the internal sphincter mechanism and posterior rectal wall.
  • Step 3: Exposure of the Fistula - The internal sphincter mechanism and posterior rectal wall are divided to expose the fistula. An incision is made around the fistula, which is then extended to the opening in the urethra.
  • Step 4: Mobilization - The rectal wall is undermined and mobilized to facilitate closure. The opening in the urethra is then closed to restore normal anatomy.
  • Step 5: Creation of Rectal Wall Flaps - Rectal wall flaps are created and sutured over the opening in the rectum to ensure proper closure and healing.
  • Step 6: Closure of Incision - The incision in the posterior rectal wall is closed, and the internal sphincter is reapproximated to restore function.
  • Step 7: Colostomy (if necessary) - If the closure of the rectourethral fistula is performed using an approach other than abdominal, a colostomy may be created to divert stool from the rectum. This involves mobilizing a segment of the colon and bringing it to the abdominal wall, where a stoma is created.
  • Step 8: Stoma Creation - If a loop colostomy is performed, the loop is brought out of the abdominal wall at the stoma site, incised longitudinally, and the edges are folded back to expose the mucosa, which is sutured to the abdomen, creating two stomas: one for stool elimination and another, known as a mucous fistula, for mucus elimination.

3. Post-Procedure

Post-procedure care following the closure of a rectourethral fistula typically involves monitoring for complications such as infection or leakage from the surgical site. Patients may require a temporary colostomy to divert stool while the rectal wall heals. Recovery time can vary based on the surgical approach used and the patient's overall health. Follow-up appointments are essential to assess healing and ensure that the fistula has been successfully closed. Patients should be educated on signs of complications and the importance of adhering to postoperative care instructions to promote optimal recovery.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
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).
