Resectoscopic treatment of uterus didelphys with unilateral imperforate vagina complicated by hematocolpos and hematometra: case report.

Objective: To describe a technique for treating hematocolpos and hematometra in patients with uterus didelphys and unilateral imperforate vagina involving the use of resectoscopy under ultrasonographic control.
Design: Case report.
Setting: University hospital.
Patient(s): A 13-year-old girl with uterus didelphys with unilateral hematometra, hematocolpos, and ipsilateral renal agenesis. The girl complained of severe abdominal pain, which appeared with each of her menses.
Intervention(s): The intervention was performed by a vaginoscopic approach to preserve the integrity of the hymen. The first incision on the vaginal wall was performed in correspondence with the hematocolpos under continuous ultrasonographic guidance with the use of a straight resectoscopic loop. Resection of the vaginal septum was continued with the use of an angled resectoscopic loop until almost complete excision of the septum was achieved.
Main Outcome Measure(s): Clinical, echographic, and vaginoscopic findings before the operation and 2 and 6 months after the operation.
Result(s): The surgical procedure was easy to perform. Almost complete excision of the septum was achieved with just a few passages of the resectoscope. Complete drainage of both the hematocolpos and the hematometra was confirmed by ultrasonography. The postoperative period was completely uneventful. Clinical and vaginoscopic evaluations 6 months after the operation confirmed the integrity of the hymen, the complete resolution of clinical symptoms, and the persistence of a large communication between the two vaginas.
Conclusion(s): Resectoscopic excision under ultrasonographic guidance of the vaginal septum in a girl with uterus didelphys with unilateral hematometra and hematocolpos was effective and easy to perform, and it fully respected the integrity of the reproductive system.
