Fig. 2: Gross findings.

a Macroscopical appearances 7 months after surgery, showing the inside of three vaginal canals with uterine outlets in the top of the pictures. The dotted lines mark the edges of the graft zones with scar tissue rims. Scale = 1 cm. b Vaginoscopy images taken three months after surgery to assess luminal morphology around the graft zones, showing air bubbles, various degrees of scar tissue, but no strictures. Green arrows point at anatomical variations, the top arrow marks the vagina with an angulation, and the bottom arrow points at a septum between the two uterine outlets. c Three-month side view X-rays of contrast-filled vaginal cavities without signs of functional strictures in any of the subjects. The asterisks mark two vaginas with anatomical variations. As a reference, a circular scale was placed around the right knee joint, depicting 1 cm in diameter.
