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.

Figure

• 

  Fig. 1 An oval cystic mass protruding through the urethral meatus.

• 

  Fig. 2 Abdominal ultrasonography revealed dilatation of the upper pole collecting system of the right kidney, draining ureter, and an ureterocele in the bladder.

• 

  Fig. 3 Magnetic resonance imaging showed a markedly dilated upper pole collecting system of right kidney in association with a large ureterocele.

• 

  Fig. 4 In voiding cystourethrography, there was an ovoid and well defined fi lling defect distal to the widened urethra. Vesicoureteral reflux was not observed.
