To explore the influence of hysteroscopic endometrial polypectomy (TCRP) for treating women on their pregnancy outcomes by in vitro fertilizationembryo transfer (IVF-ET) after operation. Methods: The clinical data of 82 infertile patients with endometrial polyps who had received IVF-ET were analyzed retrospectively. There women were divided into control group and study group (41 cases in each group) according to different treatment methods. The women in the study group were treated with TCRP and the women in the control group were treated with hysteroscopic curettage. The classification and parameters of endometrial blood flow signal of the women in the two groups were observed. And the pregnancy outcomes of the women were compared between the two groups. Results: The rate of type a of endometrial blood flow signal on the embryo transfer day of the women in both groups in IVF-ET was significantly higher than that before operation, and which of the women in the study group was significantly higher than that of the women in the control group. The values of resistance index (RI) and pulsation index (PI) of the women in both groups were significantly lower than those before operation, and which of the women in the study group were significantly lower than those of the women in the control group. The clinical pregnancy rate of the women (58.5%) in the study group was significantly higher than that (34.2%) of the women in the control group (all P<0.05). There was no significant difference in the biochemical pregnancy rate (2.4% vs. 7.3%) of the women between the two groups (P>0.05). Conclusion: TCRP can improve endometrial receptivity of the patients with endometrial polyps, and which is beneficial to improve the pregnancy outcomes of patients with endometrial polyps in IVF-ET.
