Congenital Anterior Urethral Diverticulum: Antenatal Diagnosis With Subsequent Neonatal Endoscopic Management.

Congenital anterior urethral diverticulum is a rare cause of urethral obstruction in boys. We report on the antenatal diagnosis of this rare phenomenon, making this the sixth prenatally diagnosed case in the English literature (to the best of our knowledge). Our initial prenatal assessment, postnatal endoscopic management, along with the eventual clinical course is outlined. The embryologic theories, differential diagnosis, literature review, imaging, and treatment modalities of this entity are discussed. [ABSTRACT FROM AUTHOR]
