Objective: To demonstrate the applicability and adaptability of UFS-QoL in evaluating treatment effectiveness in Chinese populations. Design: Secondary analysis of a prospective cohort study. Setting: 20 Chinese hospitals Population or sample: 2411 Chinese women with symptomatic fibroids. Methods: Patients completed UFS-QoL and short form-36 (SF-36) at pre-surgery, 6 months, and 12 months after surgery. Evaluating the extent to which items comprising UFS-QOL the same concept in Health-related Quality of Life (HRQL) is obtained by calculating the Cronbach’s α coefficient. Relationships between items and domains were established using principal axis factor analysis with orthogonal rotation. Correlation between UFS-QoL and SF-36 was estimated by Spearman’s correlation. The ability to detect change was evaluated by comparing pre- and post-treatments and 6- and 12-month scores using mixed effect models. Main outcome measures: Internal reliability, convergent validity, criterion validity, and responsiveness. Results: Exploratory factor analysis yielded six factors with eigenvalues >1. A 63.61% total variance was explained by the test items. Ceiling effects of self-consciousness and sexual functioning were >15%. UFS-QoL showed a positive and moderate correlation with SF-36, with good consistency reliability (Cronbach α>0.7 in all subscales) and ability to detect change after treatment, except for self-consciousness (Cronbach α =0.56), which showed both lowest effect size (0.38) and SRM (0.38) in 6 and 12 months after treatment Conclusions: Symptom severity, activity, and mood domains were valid and reliable in the Chinese UFS-QoL. However, self-consciousness domain needs further investigation on cultural adjustment, for example, cognitive debriefing for how Chinese interpret those questions.

Objective To assess the safety and clinical efficacy of high-intensity focused ultrasound (HIFU) combined with gonadotropin-releasing hormone agonists (GnRH-a), hysteroscopic surgery (hysteroscopic resection of adenomyosis and endometrial ablation) and levonorgestrel intrauterine system (LNG-IUS) for the treatment of adenomyosis patients with an unsatisfactory HIFU ablation. Design A retrospective analysis. Setting A specialized hospital in China. Population In all, 25 adenomyosis patients with HIFU ablation, the the non-perfused volume (NPV) ratio＜50%, without fertility requirement. Methods All patients underwent HIFU ablation combined with GnRH-a, hysteroscopic surgery and LNG-IUS treatment (HGHL), with a follow-up period of at least 12 months. Main outcome measures The changes in dysmenorrhea and menstrual volume before, and at 3, 6 and 12 months following HGHL treatment. Results All 25 patients enrolled in the study were successfully treated with the HGHL combination with a median follow-up length of 15 months (range, 12–30 months). Mean value of the NPV ratio calculated immediately after the HIFU treatment was (32.8±10.4)%. Mean operation time, median intraoperative blood loss and median length of hospital stay of hysteroscopic surgery were 42.9±12.8 min, 10 (5,15) ml, and 3 (3,3) days, respectively. No significant complications were observed during HGHL treatment. Compared with the symptom scores before the HIFU treatment, the score of dysmenorrhea and menstrual volume decreased significantly at 3, 6 and 12 months after HGHL treatment ( p< 0.05), and no significant difference was observed between 3, 6 and 12 months after HGHL treatment ( p> 0.05). No recurrence was observed during the follow-up. Conclusions HGHL is a novel and effective combination therapy for adenomyosis with unsatisfactory HIFU ablation with the goal of preserving as much of the uterus as possible.
