An ectopic ureterocele presented as a prolapsed vaginal mass in a 1-month-old girl / 대한산부인과학회지

An ectopic ureterocele is a rare condition in the neonate, especially one that protrudes from the outside of vagina as a site of termination of an ectopic ureter. In such a case, the differential diagnosis with inspection between an ectopic ureterocele and other vaginal mass is difficult. As well, recurrent episodes of urinary tract infection and sepsis are common. Recently, incision of an ectopic ureterocele has led to a decrease in compression due to obstruction of the urinary tract and fewer complications arising from surgery of the urinary system in infant. The authors present an example of a interlabial mass that appeared suddenly in a 1 month old neonate in which marsupialization of the prolapsed ectopic ureterocele was carried out.
