A rare case of symptomatic hydrometrocolpos in a 5y old female.

Late presentation of symptomatic hydrometrocolpos is uncommon. We present a 5 years old continent girl with prenatally diagnosed multicystic dysplastic left kidney and late-onset of lower abdominal pain. Investigations revealed a nonfunctioning left kidney with an ectopic ureter draining into the left hemivagina, and a vaginal duplication with an obstructed and urine-filled left hemivagina.
