AT BIRTH, a newborn female had a mass protruding from between the labia majora (Figure 1). The mass measured 3 cm in diameter and varied in size with respiration. It was soft to palpation and decompressed into the introitus with pressure. No evidence of bleeding was noted. The remainder of the physical examination of the newborn was unremarkable. A voiding cystourethrogram was performed (Figure 2).

Denouement and Discussion  Ectopic Ureterocele Prolapsing Through the UrethraA ureterocele is a cystic dilation of the submucosal portion of the terminal intravesicular ureter.
