Purpose:
To report the author's experience on a mini-invasive technique using bioprosthetic plug and a rectal wall flap advancement in the treatment of recurrent recto-urethral fistula.
Materials And Methods:
Between 2013 and 2015, seven patients with recurrent recto-urethral fistula were referred to the Pederzoli Hospital, Peschiera del Garda, Verona, Italy. Intraoperatively all patients were found to have a rectal wall lesion and were treated with urinary and fecal diversion. For the persistence of the fistula, all the patients underwent a mini-invasive treatment consisting on placement of a bioprosthetic plug in the fistula covered by an endorectal advancement flap through a trans-anal and trans-urethral combined technique.
Results:
Median operative time was 48 min with a median blood loss of 30 ml. Median hospital stay was 3 days (IQR 1-3). No case of fistula recurrence or plug migration was described. None of the patients experienced fecal or urinary incontinence. All patients obtained complete fistula healing.
Conclusions:
Recurrent recto-urethral fistula is a challenging postsurgical complication for surgeons and urologists, and its best treatment is still unknown. Our method seems to be feasible and effective for the treatment of complex recto-urethral fistula.
