Hypospadias in Children

A concise evidence-based overview of hypospadias assessment, surgical goals, complications, long-term follow-up, and what remains uncertain.

Educational overview. This page does not provide medical advice for an individual child.

Clinical overview

Hypospadias is a congenital condition in which the urethral opening (meatus) is located on the ventral surface of the penis proximal to its usual glanular position. It may be associated with ventral penile curvature and a dorsally hooded foreskin.

Hypospadias is not defined by meatal location alone. Severity and surgical complexity depend on the whole penile anatomy, including curvature, the quality of the urethral plate and glans, penile size, and the tissue available for repair. This is the point of the Academy episode “Hypospadias Is Not a Meatal Diagnosis”.

Treatment is surgical. Its timing and technique are individualized, and no single technique is best for every child.

What clinicians assess

Meatal location
Where the meatus lies. This describes one feature of the anatomy and does not by itself determine severity or complexity.
Ventral curvature
Whether the penis curves ventrally and whether the curvature needs to be corrected. Curvature is assessed separately from meatal location.
Urethral plate
The quality and appearance of the plate of tissue leading to the meatus.
Glans
The size and configuration of the glans, which bears on glans closure.
Penile size
Penile size and proportions, which are considered in operative planning.
Foreskin and available tissue
The availability and quality of foreskin and other local tissues that may be used for reconstruction.
Prior surgery
Whether a repair has already been done, and the condition of the tissue afterward.

Meatal location, curvature, penile anatomy, and tissue quality

These features are considered together. The meatus is the most visible finding, but curvature, plate quality, glans size, penile size, and tissue quality each affect the repair.

For this reason a distal meatus does not by itself define a simple repair, while proximal hypospadias more often raises additional reconstructive decisions, including whether repair is performed in one stage or stages. Both are discussed in the Academy (“Distal Hypospadias: The Myth of the Simple Repair” and “Proximal Hypospadias: One Stage or Two?”).

Primary and reoperative hypospadias

Primary repair is the first operation. Reoperative (redo) repair follows an earlier repair, often in scarred tissue and altered anatomy, so the available tissue and the anatomy differ from the primary setting. Redo cases are assessed individually, and this page makes no general statement about expected results.

Surgical goals

The goals of repair include correction of significant curvature, creation of an adequate-calibre neourethra with a glandular meatus in a functionally appropriate position, a urinary stream without clinically important obstruction or spraying, and an acceptable appearance.

Appearance is one goal and not the only one. Function matters, including urinary stream and, later in life, sexual and reproductive considerations. Whether the right outcomes are being measured is discussed in the Academy (“Cosmetic versus Functional Success”).

Complications and long-term follow-up

Problems monitored after repair include urethrocutaneous fistula, meatal stenosis or urethral stricture, glans or wound dehiscence, residual or recurrent curvature, and voiding dysfunction. This page does not quote complication rates.

Follow-up may need to extend through puberty and transition to adult care because urethral narrowing, voiding dysfunction, recurrent curvature and concerns about appearance or sexual and ejaculatory function can become apparent years after repair (Academy: “Long-Term Adult Outcomes After Childhood Hypospadias Repair”).

What remains uncertain

  • how to define and measure success beyond appearance
  • long-term urinary, sexual, and reproductive outcomes into adulthood
  • one-stage versus staged repair in proximal hypospadias
  • the best timing of surgery for an individual child
  • which repairs are at risk of failure, and why
  • how best to protect the repair against fistula
  • how to approach redo surgery when tissue quality is poor
  • which patients, if any, derive meaningful benefit from preoperative hormonal treatment

Pediatric Urology Academy

The Pediatric Urology Academy includes a dedicated season on hypospadias (Season 4, 15 episodes). Topics include:

  • hypospadias is not a meatal diagnosis
  • urethral plate assessment
  • glans size and glans closure
  • distal hypospadias and the myth of the simple repair
  • ventral curvature and straightening before urethroplasty
  • testosterone before hypospadias repair
  • proximal hypospadias: one stage or two
  • STAG versus STAC in proximal hypospadias
  • timing of hypospadias surgery
  • TIP repair after three decades
  • grafting: preputial skin and buccal mucosa
  • preventing fistula: dartos, tunica vaginalis, coverage layers, and pressure
  • redo hypospadias
  • cosmetic versus functional success
  • long-term adult outcomes after childhood hypospadias repair
