Abstract

OBJECTIVES. Obstructive uterovaginal duplication is rare and frequently misdiagnosed. The aims of this study were to review all the patients managed for this malformation in our institution, evaluate their long-term outcomes, and discuss the embryologic origin of this malformation. METHODS. From 1984 to 2007, we treated 32 patients for obstructive uterovaginal duplication in our institution. We separated them in 2 groups (prepubertal [n = 8] and pubertal [n = 24]) and analyzed their clinical and radiologic presentations and their treatments. Patients >18 years of age (n = 22) were recontacted. RESULTS. For the prepubertal group, the median age at diagnosis was 6 months. Postnatal ultrasound showed an absent ipsilateral kidney in 6 case subjects, although 4 patients had a prenatal diagnosis of ipsilateral multicystic dysplastic kidney. This renal anomaly was associated with a pelvic sonolucent mass in 3 case subjects, allowing us to prenatally suspect the diagnosis. All of the patients were cured by vaginal approach. For the pubertal group, the median delay of diagnosis after menarche was 9 months. Among patients managed in an emergency setting (n = 11), there were 9 misdiagnoses with inappropriate abdominal surgeries, including 3 hysterectomies of the obstructed hemiuterus. Concerning long-term results, 5 patients were attempting to have children, with successful pregnancies for 4 of them. One patient suffered from infertility attributable to contralateral isthmic stenosis after a hysterectomy of the obstructed hemiuterus. CONCLUSIONS. Obstructive uterovaginal duplication is a benign pathology when properly managed. Therefore, management of abdominal pain in peripubertal girls should include systematic abdominal and gynecologic examinations completed by radiologic pelvic and renal evaluation. Surgical treatment should be performed by vaginal approach to avoid infertility. Concerning the origin of the malformation, the high association of prenatal dysplastic kidneys and postnatal absent kidneys suggests anomalies of both wolffian and müllerian duct development, contrasting with the classic definition of this malformation.
