Treatment of a Recurrent Rectourethral Fistula by Using Transanal Rectal Flap Advancement and Fibrin Glue: A Case Report

ABSTRACT

Rectourethral fistulas (RUFs) in adults are rare and could result from complicated trauma, and prostatic or rectal surgery. RUFs have been treated initially by using primary repair and omental interposition with or without a colostomy during surgery. Recurrent RUFs require complex surgery, such as a low rectal resection and coloanal anastomosis, an interposition flap of the datos muscle or gracilis muscle, and others. Recently, transanal rectal flap advancement and fibrin glue injection have provided an effective occlusion of RUFs. However, no reports about this technique exist for cases of recurrent RUFs. We report a case of a recurrent RUF successfully repaired by using transanal rectal flap advancement combined with fibrin glue injection into the fistula tract. The postoperative course was uneventful without complications. At the 1-year follow-up, no complications such as urethral stricture or recurrence existed, and voiding was normal without anal incontinence.
