Hysteroscopic Corrections for Complete Septate and T-Shaped Uteri Have Similar Surgical and Reproductive Outcome

Aim: To compare the surgical results and reproductive performances of patients with ESHRE/ESGE (European Society for Human Reproduction and Embryology/European Society for Gynaecologic Endoscopy) class U1a and U2b uterine anomalies after hysteroscopic correction. Methods: A retrospective cohort study was conducted at a university hospital infertility clinic. Ninety-six patients with class U2b (complete septate uterus) and 78 patients with class U1a (T-shaped uterus) uterine anomalies who underwent hysteroscopic correction between January 2009 and December 2015 were recruited. Results: The operation time was significantly longer in class U2b anomalies (26.5 +/- 5.3 minutes) than class U1a anomalies (22.8 +/- 5.8 minutes; mean difference [95% confidence interval [CI]: 3.6 +/- 0.9 [1.8-5.3]; P < .001). Six out of all complete septate patients and 3 of T-shaped patients were reoperated due to postoperative synechia or to further enlarge the cavity. There were no differences between the groups regarding intraoperative (blood loss and uterine rupture) and postoperative (bleeding and infection) complications. After surgical correction, the term delivery rates increased from 3% to 71% (P < .001) in class U2b and from 4% to 62.1% (P < .001) in class U1a. The chance of live birth significantly increased after hysteroscopic correction both in class U2b (odds ratio [OR] 106.1; 95% CI, 29.1-387.1; P < .001) and class U1a (OR 35.7; 95% CI, 11.6-109.9; P < .001). The postoperative reproductive performances of both anomalies were similar. Conclusion: Both types of anomalies seem to have similar severity and prognosis. Patients with both types of anomalies have excellent reproductive outcome after hysteroscopic correction.
