Methods: In this prospective, comparative, and cohort study, participants who were candidates for septum resection were recruited during 2015-2018. The uterine septum was removed using hysteroscopic scissors or a resectoscope. The second-look hysteroscopy was performed in the follicular phase after two months. In the second-look hysteroscopy, surgery outcomes were evaluated, and the residual septa or adhesions were removed in case of incidence. The study followed participants for up to five years to observe pregnancy outcomes. This involved recording the duration from hysteroscopy to pregnancy and determining if these pregnancies led to live births.

Results: A total of 119 female patients with a mean age of 30.20 ± 6.14 years were enrolled in this study, out of who 62 cases (52.1%) were in the hysteroscopic scissors group, and 57 cases (47.9%) were in the resectoscope group. The 63 (52.9%) cases had primary infertility, and the prevalence of abortion was 46 (38.7%). During the second look, hysteroscopy adhesion was diagnosed in 18 cases (15.1%), and septum residue was seen in 49 cases (67.1%). The adhesion rate in the hysteroscopic scissors group was higher than that in the resectoscope group, but it was insignificant (P = 0.223). At the second follow-up stage, only 85 patients out of 119 ones were available. The successful pregnancy rate was 46 out of 85 (54.1%). The mean age of the patients in the successful pregnancy group was significantly lower than that in the unsuccessful pregnancy group (P < 0.001).

Conclusion: There were no differences among resectoscope and hysteroscopic scissor methods’ outcomes in term of metroplasty associated with septate uterus (SU).
