Hypospadias, a common congenital penile defect, results from urethral groove fusion failure during development. Surgical repair between 6-12 months aims to correct functional and aesthetic issues, though complications like fistulae can occur.

Area of Science:

  • Pediatric Urology
  • Congenital Malformations
  • Surgical Reconstruction

Background:

  • Hypospadias is a congenital penile anomaly characterized by ventral urethral hypoplasia and an ectopic meatus.
  • It arises from a fusion defect of the urethral groove between the 11th and 18th developmental weeks, with earlier arrest leading to more severe proximal forms.
  • Affecting 1 in 250 male births, its etiology is multifactorial, including genetic, endocrine, placental, and environmental factors.

Purpose of the Study:

  • To provide a comprehensive overview of hypospadias, encompassing its embryology, classification, diagnostic workup, and surgical management.
  • To highlight the critical timing and techniques for surgical intervention to minimize functional and aesthetic sequelae.
  • To discuss common postoperative complications and the necessity of long-term psychological support.

Main Methods:

  • Review of existing literature on hypospadias etiology, classification, and treatment modalities.
  • Description of the embryological basis of hypospadias and its impact on classification.
  • Outline of surgical principles including penile straightening, urethroplasty, and ventral reconstruction, utilizing sutures, flaps, or grafts.

Main Results:

  • Hypospadias presents in proximal, middle, and distal forms, with distal being most common.
  • Preoperative investigations (endocrine, genetic, morphological) are crucial for severe cases to guide pubertal prognosis.
  • Surgical outcomes show complication rates between 6-30%, primarily fistulae and stenoses, necessitating experienced surgical teams.

Conclusions:

  • Timely surgical intervention (6-12 months) is essential for optimal functional and aesthetic results in hypospadias.
  • A multidisciplinary approach, including psychological follow-up into adulthood, is vital for comprehensive patient care.
  • Hypospadias surgery demands specialized expertise due to its complexity and potential for complications.
