Single ectopic ureter ureter is very rare and it accompanies renal anomaly commonly. We experienced a case of single ectopic ureter of which orifice opened into the uterine cervix in 18 year girl. She had suffered from urine leakage through the vagina in spite of normal voiding since childhood. Nephroureterectomy was performed and surgical specimen revealed hypoplastic kidney and marked hydroureter. We report this case with review of literatures.
