High-resolution prostatic ultrasonography confirmed the presence of prostate glands and seminal vesicles in patients with bladder exstrophy-epispadias complex. However, most showed abnormal size, position, or appearance, suggesting developmental or surgical influences.

Area of Science:

  • Pediatric Urology
  • Embryology
  • Medical Imaging

Background:

  • The bladder exstrophy-epispadias complex is a rare congenital condition affecting the genitourinary system.
  • Understanding the development of the prostate and seminal vesicles in these patients is crucial for clinical management.

Purpose of the Study:

  • To evaluate the presence, appearance, and characteristics of the prostate gland and seminal vesicles in patients with bladder exstrophy-epispadias complex using high-resolution prostatic ultrasonography.

Main Methods:

  • High-resolution prostatic ultrasonography was performed on seven patients diagnosed with bladder exstrophy-epispadias complex.
  • Detailed analysis of the size, position, echogenicity, and morphology of the prostate gland and seminal vesicles was conducted.

Main Results:

  • Prostate glands were present in all evaluated patients, with variations in size (normal, small, or unidentifiable) and unusual positions or echogenicity observed in most.
  • Seminal vesicles were frequently enlarged, cystic, or abnormally positioned, extending beyond the prostate gland in five patients.
  • These findings suggest potential embryologic abnormalities or postsurgical changes impacting these structures.

Conclusions:

  • The prostate gland and seminal vesicles are consistently present in patients with bladder exstrophy-epispadias complex.
  • Abnormalities in size, position, and echogenicity of these structures are common, likely stemming from faulty embryologic development or surgical interventions.
  • Enlarged seminal vesicles may indicate impaired drainage, possibly related to initial bladder closure or subsequent reconstructive surgeries.
