Rectourethral fistula stenting: a technique for better fistula visualization and efficient repair.

In this study, the authors present a technical tip for better and easier visualization of rectourethral fistula both during dissection and fistula closure. In this technique, a small-caliber ureteral catheter is used for catheterization of the fistulous tract under direct urethroscopic guidance. Five cases were treated using this technique. All cases had either brachytherapy as a monotherapy or combined brachytherapy and external beam radiotherapy. All cases had the fistula completely healed except for one failed case that had a 2-cm fistula.
