Hysteroscopic Metroplasty: Ultrasound Parameters to Optimize Fertility Benefits?

ABSTRACT

INTRODUCTION: Metroplasty is a procedure used by some teams to correct certain uterine anomalies to improve fertility outcomes. Our goal was to evaluate hysteroscopic metroplasty in the management of nulliparous and infertile patients with a uterine anomalies. MATERIAL AND METHODS: We conducted a single-center, retrospective, observational study of women who underwent hysteroscopic metroplasty for infertility between January 1, 2015 and December 31, 2019. The primary endpoint was the occurrence of a live birth at 18 months post-surgery. The secondary endpoint was to identify predictive factors for the success of the procedure, in particular ultrasound criteria, and live-birth rate during total follow up. RESULTS: We included 43 nulliparous patients with an average of 5.2±-2.4 years of primary infertility, including 84.2% patients who had at least one IVF cycle prior to the surgery. The mean age was 37±5 years. The post-surgery live-birth rate was 27.9% at 18 months and 53.5% during the total postoperative follow-up (mean follow-up 4.5±1 years). Pregnancies were obtained spontaneously after surgery for 8/28 (28.6%) patients who were undergoing assisted reproduction technology before surgery. No intra- or postoperative complications were recorded. We did not identify any predictive ultrasound factors, pre- or postoperatively, for a live birth at 18 months post-surgery. DISCUSSION: Hysteroscopic metroplasty appears to improve the chances of a live birth in a population of nulliparous and infertile patients with at least one uterine pathology. Spontaneous pregnancy can occur after hysteroscopic metroplasty. The Congenital-Ultrasound-Malformation-by-Expert ultrasound criteria do not appear to be predictive of post-surgery outcomes.
