Introduction: When a patient with an obstructed hemivagina presents in childhood, either hormonal suppression or a staged procedure is proposed for management of the obstruction.
Case Report: This case report is a 12-year-old patient presenting for evaluation of hematocolpos with a complete septate uterus, duplicate cervices, bilateral kidneys, and obstructed left hemivagina who was surgically managed with a complete vaginal septum resection and hysteroscopic metroplasty in one procedure shortly after diagnosis.
Conclusion: This anomaly is not only rare, and the first presented in the literature, but it also importantly demonstrates that if desired by the family after a consideration of benefits and risks, resection of both vaginal and uterine septa can be safely performed in a young post-menarchal patient without the need for a staged procedure later in life.
