Obstetric Outcomes of Singleton Birth After Hysteroscopic Septoplasty of Complete Uterine Septum

Objective: The aim of this research was to determine the obstetric outcomes in patients who had singleton live birth after hysteroscopic septoplasty of complete uterine septum (CUS) that reached the internal or the external cervical os. Materials and Methods: This retrospective study included 112 patients, each with a history of reproductive failure between 2002 and 2019. Of these patients, 29 each had a singleton live birth after hysteroscopic septoplasty for CUS (group 1) and 83 each had a singleton live birth after hysteroscopy revealed a normal uterine cavity (group 2). In group 1 the septum reached the internal or the external cervical os in 16 and 13 patients, respectively. Subgroup analysis was performed of 24 patients: 8, in whom the septum reached the external cervical os (group 1a); and 16, in whom the septum reached the internal cervical os (group 1b). Results: There was no significant difference in incidence of premature birth (12.5% versus 12.2%) or other pregnancy complications, gestational age, or newborn birth weight between group 1 and group 2, respectively. Obstetric outcomes between the 2 subgroups were also similar. Conclusions: The study data suggest favorable obstetric outcomes for singleton gestation after hysteroscopic septoplasty of CUS reaching the internal or external cervical os. Division of cervical septum was not associated with cervical insufficiency.
