Zhu weili.?. Clinical application of Navosure impedance to control endometrial ablation system in treating abnormal uterine bleeding[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2014, 44(5): 376-.
Abstract：Objective: To assess the feasibility, safety and effectiveness of Novasure impedance to control endometrial ablation system in the treatment of abnormal uterine bleeding. Methods: From June 2011 to June 2013, 50 women with abnormal uterine bleeding who received Novasure system for treatment were retrospectively analyzed. The clinical effect and complications were followed up in months 1, 3, 6, 12, 24. Results: The procedures were completed successfully in all patients. The work time of the radio frequency was (80.57±4.38) s (ranged from 57~128 s). The average duration of the operation including anesthesia was (15±4.6) min. The blood lost was less than 10 mL during the operation. The average hospitalization time after operation was (40±7.2) h. All the patients were followed-up for 24 months. The effective rates in 1, 3, 6, 12 and 24 months were 100% (50/50), 90% (45/50), 86% (43/50), 92% (46/50) and 96% (48/50) respectively. The rate of amenorrhea was 46% (23/50), 50% (25/50), 48% (24/50), 54% (27/50) and 76% (38/50) respectively. The degrees of satisfaction were 100% (50/50), 90% (45/50), 90% (45/50), 92% (46/50) and 96% (48/50). No severe perioperative or postoperative complications occurred. Conclusion: Novasure impedance controlling endometrial ablation system which is worth promoting in clinical is safety and effective in the treatment of abnormal uterine bleeding.
