Reproductive performance and obstetric outcomes after hysteroscopic septum resection

PurposeThe aim of this retrospective cohort study was to investigate the effects of hysteroscopic uterine septum resection on the clinical pregnancy rate (CPR), live birth rate (LBR) and miscarriage rate.Materials and Method(s)Hospital records of consecutive patients who underwent hysteroscopic uterine septum resection between February 2021 and December 2022 were reviewed. They were telephoned and interviewed about their reproductive performance after surgery, and pregnancy outcomes, if achieved.Results and ConclusionsSixty-nine eligible patients were enrolled. Forty-one (59.4%) of these patients were referred to our clinic for otherwise unexplained infertility of at least 1 year and 28 (40.6%) for pregnancy loss. During the follow-up period, 32 patients conceived. The overall CPR was 46.4%, the LBR per woman was 36.2%, the LBR per pregnancy was 78.1% and the miscarriage rate was 12.5%. The LBRs per pregnancy were 83.3% and 71.4% in the infertility and miscarriage subgroups, respectively. The miscarriage rates per pregnancy were 0% and 28.6% in the infertility and miscarriage subgroups, respectively. Three of 6 patients whose uterine septum was incomplete but prominent became pregnant (CPR: 50.0%), and all pregnancies resulted in live birth (LBR per pregnancy:100%, LBR per woman:50%). Two patients with complete uterine septum didn't achieve pregnancy. Hysteroscopic uterine septum resection may improve the CPR, LBR and miscarriage rates in subfertile population with and without previous pregnancy loss.
