Effect of high intensity focused ultrasound (HIFU) uterine fibroid ablation on the endometrial receptivity and sex hormone level in uterine fibroid patients and the influencing factors for treatment rate were investigated. A retrospective analysis of 266 uterine fibroid patients admitted to the Department of Gynaecology in the Jining Maternity and Child Care Hospital from October 2013 to October 2016 was performed. Among them, observation group was treated with HIFU ablation (n=143), control group with myomectomy (n=123). The pulsatility index (PI) and the resistance index (RI) of the uterine arterial blood flow were measured during the luteal phase of menstruation by transvaginal ultrasonography. The serum luteinizing hormone (LH), follicle stimulating hormone (FSH) and estradiol (E 2 ) were detected by chemical immunofluorescence. The relationship between HIFU treatment rate and clinical pathology of uterine fibroid patients was analyzed, and univariate/multivariate regression analysis was used to analyze the influencing factors for HIFU treatment rate. There was no significant difference in preoperative and postoperative PI and RI between the two groups (P&gt;0.05); no significant difference between preoperative and postoperative PI/RI in the same group (P&gt;0.05). There was no significant difference in preoperative and postoperative LH, FSH and E 2 between the two groups (P&gt;0.05); no significant difference between preoperative LH and postoperative LH in the same group (P&gt;0.05), neither FSH or E 2 (P&gt;0.05). Results of multivariate analysis showed that fibroid location and ultrasound contrast intensity were independent influencing factors for HIFU treatment rate (P&lt;0.05). Treatment of uterine fibroid with HIFU has no effect on the patient's endometrial receptivity and sex hormone level. Fibroid location and ultrasound contrast intensity are independent risk factors for HIFU treatment rate. This study provides guidance for the clinical optimization of treatment methods and is more conducive to the promotion of HIFU ablation therapy.
