Management of severe hypospadias with a 2-stage repair
Insights
A two-stage surgical repair for severe hypospadias in children offers better cosmetic outcomes and fewer complications. This method is ideal for complex cases involving chordee and small phallus, improving functional results.
Area of Science:
- Pediatric Urology
- Reconstructive Surgery
Background:
- Hypospadias is a congenital condition affecting the urethral opening.
- Severe cases present challenges, including chordee and a small phallus.
Purpose of the Study:
- To evaluate the efficacy of a two-stage surgical repair for severe hypospadias.
- To compare this approach with single-stage repairs using grafts.
Main Methods:
- A retrospective review of 58 children with severe hypospadias treated between 1986-1993.
- Two-stage repair involving chordee correction, flap advancement, and subsequent glanular/urethral reconstruction.
- Use of penile nerve block and biomembrane dressing for early mobilization.
Main Results:
- Excellent functional and cosmetic results were achieved in the treated cohort.
- The two-stage approach demonstrated a lower complication rate compared to single-stage repairs with grafts.
- This method is particularly beneficial for patients with severe proximal hypospadias, chordee, and a small phallus.
Conclusions:
- A two-stage surgical repair is a highly effective treatment for a specific subset of children with severe hypospadias.
- This technique provides superior cosmetic and functional outcomes with reduced complications.
Abstract:
From 1986 to 1993 we treated 1,437 children with hypospadias of whom 58 had scrotal or perineal hypospadias with severe chordee and a small phallus. These patients underwent a 2-stage surgical repair. The first stage of the procedure included correction of the chordee and advancement of preputial flaps ventrally and distally to the superior aspect of the glans. After 6 to 12 months the second stage of the procedure was performed using the previously transferred preputial skin to reconstruct the glans and urethra. A second layer of subcutaneous tissue or tunica vaginalis was used in several instances. A penile nerve block and a transparent biomembrane dressing (Tegaderm) allowed for early postoperative mobilization. Excellent functional and cosmetic results were achieved. There is a subset of patients with severe proximal hypospadias, chordee and a small phallus who may benefit best from a 2-stage procedure. In these children a 2-stage repair allows for a better cosmetic appearance and a lower complication rate than a 1-stage repair with a free or vascularized graft.
