Penile length in adulthood after exstrophy reconstruction

Summary

Penile length in adulthood after bladder exstrophy reconstruction is often short due to a congenital deficiency in the corpora cavernosa size. Surgical correction may improve appearance but cannot fully restore normal penile length.

Area of Science:

  • Urology
  • Pediatric Surgery
  • Anatomy

Background:

  • Bladder exstrophy reconstruction is a complex surgical procedure.
  • Adult penile length after reconstruction is a significant concern for patients.

Purpose of the Study:

  • To investigate if adult penile shortness after exstrophy reconstruction is linked to congenital defects in corpora cavernosa size.
  • To compare penile and pelvic anatomy in men with a history of exstrophy reconstruction to controls.

Main Methods:

  • Pelvic MRI was used to assess penile and pelvic anatomy.
  • 10 men post-exstrophy reconstruction were compared with 10 age- and race-matched controls.

Main Results:

  • Men post-exstrophy reconstruction had shorter corpora cavernosa compared to controls.

  • The anterior segment of the corpora cavernosa was short, while the posterior segment was normal in length but increased in diameter.
  • Pubic symphysis diastasis increased distances between structures but did not alter the angle between the corpora cavernosa.

    • Conclusions:

    • Adult penile shortness after exstrophy reconstruction is partly due to congenital corporeal tissue deficiency.
    • Surgical interventions like pubic symphysis approximation and chordee correction may enhance penile visibility and cosmesis.
    • However, inherent shortness of the corpora cavernosa means adult penile length will likely remain below normal after exstrophy reconstruction.
