NovaSure impedance controlled system for endometrial ablation: the experience of the first UK reference centre.

In this study we assessed the effectiveness of the NovaSure Impedance Controlled Endometrial Ablation System for the treatment of menorrhagia in pre-menopausal women. A total of 125 pre-menopausal women with menorrhagia, which was secondary to dysfunctional uterine bleeding and unresponsive to medical therapy, had endometrial ablation using the NovaSure system between June 2004 and October 2005. A postal questionnaire was sent to all patients and the response rate was 80% (110 patients). The clinical data were analysed in 105 case notes (84%). The mean age was 43.91 +/- 5.45 SD, and mean parity was 2.09 +/- 0.65. The median treatment time was 71.00 s, ranging between 45.00 and 105.00 s. Results from a period of 18 months demonstrated that the NovaSure system was effective in reducing excessive uterine blood loss in 90.5% of patients and there were no intraoperative adverse events reported. Some 87% of patients were satisfied with the procedure and 90% of patients would be happy to recommend the treatment. We conclude that the NovaSure system is effective and safe in the treatment of symptomatic menorrhagia.
