Obstructive Müllerian anomalies: case report, diagnosis, and management

Didelphic uterus and obstructed hemivagina with renal agenesis: case report and review of the literature

Congenital disorders of development are more common than previously reported and the correct diagnosis is frequently missed leading to suboptimal treatment. Eight cases of uterus didelphys with obstructed hemivagina referred to the Gynecology service at Baylor College of Medicine over a 2-year period were reviewed. Initial presenting symptoms and signs were followed by an incorrect diagnosis by the referring physician 100% of the time. MRI, the most sensitive imaging modality for congenital anomalies (Kublik, RA: Female pelvis. Eur Radiol 1999; 9:1715), was utilized in only 50% of the cases. In this group of patients, hematocolpos and pyocolpos were discovered in equal numbers upon exploration. Ipsilateral renal anomalies were present 100% of the time, while coexisting contralateral anomalies were present 50% of the time. Resection of the vaginal septum was required for abatement of symptoms in all cases presented here. Laparoscopy provided additional information beyond radiologic tests regarding pelvic and urological anatomy. In two cases, resection of the ipsilateral uterine horn was required. These cases demonstrate the difficulty in diagnosis, heterogeneity in presentation, and need for expertise not only in this rare congenital anomaly but also all the other disorders of development of the female genital tract.

Presenting and long-term clinical implications and fecundity in females with obstructing vaginal malformations

OBJECTIVE

To evaluate presenting and long-term clinical consequences in females with obstructing vaginal anomalies.

DESIGN

A retrospective study.

SETTING

A university hospital in southern Finland.

PARTICIPANTS

Twenty-six females with obstructing vaginal malformations. The conditions were classified into transverse vaginal obstruction (transverse septum or imperforate hymen) and longitudinal vaginal obstruction (longitudinal vaginal septum). INTERVENTIOS: 13 out of 16 women with transverse vaginal obstruction underwent incision of the imperforate hymen and three underwent excision of a complete transverse vaginal septum. Ten patients with obstructing hemivagina had incision of the longitudinal vaginal septum.

MAIN OUTCOME MEASURES

Presenting symptoms and delay in diagnosis, outcome of primary surgical treatment, possible late complaints associated with obstruction, fecundity, perinatal outcome, and presence of other anomalies were studied. The mean followup period in the transverse and longitudinal obstruction group respectively was 13 years (range 1-29) and 16 years (range 1-44).

RESULTS

Transverse vaginal obstructions were diagnosed within less than a month from the primary symptoms, while the diagnosis of longitudinal obstruction was delayed for an average of 27 months. Two out of three females with transverse vaginal septum underwent re-operation for vaginal constriction and three out of 10 with longitudinal vaginal septum had re-excision of the septum. All females with longitudinal obstruction had uterine and renal malformations as opposed to those with transverse vaginal obstruction. In the transverse vaginal obstruction group, two out of the six females who had their renal status assessed had double ureters. Dysfunctional uterine bleeding (19% in the transverse and 40% in the longitudinal obstruction group), dyspareunia (30% and 0%) and dysmenorrhea (19% and 20%) were the most common complaints during the followup. No endometriosis was found in the group that underwent a subsequent laparotomy or laparoscopy (18/26). Female infertility was not found in those 14 females who were attempting to conceive. Twenty-five (89%) out of 28 pregnancies ended in delivery, the live birth rate being 82% in the longitudinal and 94% in the transverse obstruction group.

CONCLUSION

Accurate diagnosis together with adequate treatment may reduce the need for re-operations in cases with obstructing vaginal malformations. No specific gynecologic long-term clinical symptoms were identified in obstructing vaginal anomalies.
