Can a graft be placed over a flap in complex hypospadias surgery? An experimental study in rabbits

Abstract: Purpose:To develop a rabbit experimental study to test the hypothesis that surgical repair of hypospadias with severe ventral curvatures might be completed in one stage, if a graft, such as buccal mucosa, could be placed over the tunica vaginalis flap used in corporoplasty for ventral lengthening, with the addition of an onlay preputial island flap to complete the urethroplasty.Materials and methods:The experimental procedure with rabbits included a tunica vaginalis flap for reconstruction of the corpora after… Show more

“…Hence, TIPU has fallen out of favour for STAGED repair in proximal hypospadias. Concerns about a higher risk of urethroplasty failure when combined with a corporal grafting procedure in a single-stage repair have led to this paradigm shift [11][12][13]. In our study, TIPU was performed in carefully selected cases of proximal penile hypospadias with a Glans score of 1 or 2 and a Shaft score of 2 or 3 (mild to moderate chordee).…”
