Our randomized controlled trial did not show a significant decrease in the incidence of or a significant slowing of the progression of postoperative fistulas after TIP urethroplasty by the use of additional tunica vaginalis coverage. A tunica vaginalis flap is not routinely recommended but could have a selective role in proximal-type TIP urethroplasty with deficient dartos and subcutaneous tissue to cover the neourethra.
