Abstract

Interlabial mass in infant is not common. Because of similarity of symptoms and signs of those mass and less experience of gynecologist due to those rarity, differential diagnosis is not easy. In infant, there are five common interlabial masses which are prolapsed ectopic ureterocele, urethral prolapse, paraurethral cyst, hydrocolpos and rhabdomyosarcoma. Ureterocele with duplex ureter might be diagnosed, however prolapsed ureterocele through urethra is extremely rare. We found 18 months old girl with interlabial mass and diagnosed as prolapsed ectopic ureterocele by ultrasonography, magnetic resonance imaging and voiding cystourethrography. We managed by endoscopic incision of ureterocele successfully. So we report this case with a brief review of associated literatures.
