Objective To systematically evaluate the effect of hysteroscopic uterine septum resection on the pregnancy live birth rate in patients with septate uterus.Methods The randomized controlled studies and cohort studies on the impact of hysteroscopic uterine septum resection on the pregnancy live birth rate in the patients with septate uterus were retrieved from PubMed,Web of Science,CNCN.cn,and Wanfang databases.The retrieval time was from the establishment of the database to March 2024.The NOS scale was used to con-duct the literature quality evaluation.The Statal0.0 statistical software was used for conducting the meta a-nalysis,and the main evaluation index was the pregnancy live birth rate.Results A total of 9 articles on the treatment of septate uterine were included,involving 821 subjects,including 528 septate uterine patients with hysteroscopic uterine septum resection and 293 septate uterine patients with conservative treatment.The meta analysis showed that the live birth rate in the patients with septate uterine undergoing hysteroscopic uterine septum resection was higher than that in the patients with septate uterine undergoing the conservative treat-ment(I2=38.0％,OR=1.60,95％CI:1.05-2.44,P=0.028).Conclusion Hysteroscopic uterine septum resection could improve the pregnancy outcome and increase the live birth rate.It is a minimally invasive sur-gery with good effect and high safety,which has good clinical application prospects and is worth popularizing.
