An Unusual Presentation of Uterine Didelphys and Obstructed Hemivagina

Background: Congenital disorders of the genitourinary system can be unpredictable. There are both medical and surgical interventions that can help manage symptoms. Case: A 10-year-old girl was evaluated 6 months post-menarche with dysuria and pelvic pain. Her symptoms were not relieved with menstrual suppression. Evaluation revealed a probable ectopic ureter versus ureterocele and uterine didelphys with suspicion for obstructed hemivagina and hematocolpos. Surgical exploration revealed an obstructed hemivagina with a high vaginal septum. When resection failed, she ultimately underwent a robot-assisted hemihysterectomy, with resolution of her symptoms. Summary and Conclusions: In this case presentation, a surgical approach was necessary to adequately make a diagnosis. When vaginal septum resection failed, robot-assisted laparoscopic hemi-hysterectomy and resection of a vaginal pouch led to symptom resolution in this pediatric patient with a complex anomaly.
