Anterior urethral valves are a rare obstructive anomaly in males. Early diagnosis via prenatal ultrasound and initial vesicostomy can prevent complications from endoscopic procedures in neonates.

Area of Science:

  • Pediatric Urology
  • Medical Diagnostics
  • Surgical Therapeutics

Background:

  • Anterior urethral valves (AUVs) represent a rare congenital obstructive anomaly of the male urinary system.
  • Infravesical obstruction in male fetuses can indicate potential AUVs, necessitating thorough postnatal evaluation.

Observation:

  • Prenatal ultrasound identified signs of urinary tract obstruction in two male fetuses.
  • Postnatal evaluation confirmed the diagnosis of anterior urethral valves in both cases.

Findings:

  • Both patients initially underwent vesicostomy, followed by endoscopic fulguration of the valves.
  • Both patients maintained normal renal function during the follow-up period.

Implications:

Related Experiment Videos

  • AUVs must be considered in male neonates with prenatal findings of infravesical obstruction.
  • Initial vesicostomy may be a safer approach than immediate transurethral fulguration in neonates due to urethral size.
  • Prompt diagnosis and appropriate management are crucial for preserving renal function in infants with AUVs.
