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. The incidence of this abnormality is approximately 1 in 5000 to 12000 births, and the femalemale ratio is 5:1.1,2 The condition is more common in whites. The Section on Urology of the American Academy of Pediatrics classifies a ureterocele as intravesicular when it is entirely within the bladder or ectopic when some portion is situated permanently at the bladder neck
