The subcoronal meatus.

M D Gibbons, E T Gonzales

    The Journal of Urology
    |October 1, 1983

    Summary
    This summary is machine-generated.

    Meatal advancement and glanuloplasty is effective for most subcoronal hypospadias repairs. A vascularized flap offers an alternative for complex meatal variants not suitable for standard procedures.

    Area of Science:

    • Pediatric Urology
    • Surgical Innovation
    • Genitourinary Reconstruction

    Background:

    • Subcoronal hypospadias repair often utilizes meatal advancement and glanuloplasty (MAGPI) due to its success.
    • MAGPI offers excellent cosmetic outcomes, low complication rates, and short hospital stays.
    • However, certain subcoronal meatal variants (patulous, fibrotic, hypoplastic) are not amenable to MAGPI.

    Purpose of the Study:

    • To present a systematic approach for assessing subcoronal hypospadias.
    • To describe an alternative surgical technique for hypospadias repair when MAGPI is not feasible.
    • To address challenging cases of subcoronal hypospadias with specific meatal variations.

    Main Methods:

    • Review of cases with subcoronal hypospadias and associated meatal variants.

    Related Experiment Videos

  • Development of a logical assessment strategy for the subcoronal meatus.
  • Description of a vascularized meatal-based flap technique for hypospadias reconstruction.

    • Main Results:

    • Meatal advancement and glanuloplasty is highly reliable for typical subcoronal hypospadias without chordee.
    • Three distinct variants of the subcoronal meatus were identified as unsuitable for MAGPI.
    • A vascularized meatal-based flap provides a viable reconstructive option for these challenging variants.

    Conclusions:

    • A structured assessment is crucial for determining the optimal hypospadias repair strategy.
    • The vascularized meatal-based flap is an effective alternative for subcoronal hypospadias with specific meatal anomalies.
    • This approach expands the surgical armamentarium for pediatric genitourinary reconstruction.
