Combined flaps and grafts urethroplasty in severe hypospadias repair

Abstract

Severe hypospadias repair can be performed by applying different principles, either in one or in two stages. The main problem is that this form of hypospadias is usually associated with a marked chordee and short urethral plate. In these cases, the urethral plate should be divided, leading to penile lengthening and straightening. The choice of urethroplasty remains the great challenge. Different fasciocutaneous flaps (prepuce, penile skin, tunica vaginalis) and grafts (oral mucosa, bladder mucosa, skin), or combination of flaps and grafts could be used for urethral lengthening. Insufficient genital tissue in both severe and failed hypospadias causes a potential problem for urethral reconstruction. Using additional extragenital tissue offers easier correction in one-stage primary repair or staged urethroplasty in failed hypospadias. © 2014 by Nova Science Publishers, Inc. All rights reserved.
