AbstractPurpose To assess the safety and efficacy of ultrasonography (US)-guided suprapubic transvaginal (ST) radiofrequency ablation (RFA) in the treatment of symptomatic uterine leiomyomas at 1-year follow-up. Materials and Methods The institutional review board approved this prospective study, and all patients provided informed consent. ST RFA was performed as an outpatient procedure 3 days after menstruation in 51 women (age range, 32-52 years; mean age, 42.2 years) with 62 leiomyomas. The leiomyomas were assessed with conventional and contrast material-enhanced US before and after ST RFA for leiomyoma size, location, and blood flow. All patients were evaluated for postoperative complications, including abdominal pain, injury to surrounding tissues and organs, vaginal bleeding, increased vaginal discharge, fever, dyspnea, and menorrhagia, after ST RFA and at follow-up visits. The leiomyoma volumes, improvement in leiomyoma-related symptoms, effect on quality of life (QOL), and patient satisfaction were assessed and compared before and after ST RFA and at follow-up visits by using statistical analyses. Results Sixty-two leiomyomas were successfully treated with ST RFA until 90% of the leiomyoma was echogenic. At 1-month follow-up, 46 (74%) leiomyomas had no contrast enhancement, five (8%) had peripheral enhancement, eight (13%) had focal enhancement, and three (5%) had scattered enhancement at contrast-enhanced US. At 6-month follow-up, the number of leiomyomas that had no enhancement, peripheral enhancement, focal enhancement, or scattered enhancement was 43 (69%), seven (11%), nine (15%), and three (5%), respectively. The leiomyoma volumes were significantly (P < .05) reduced at 1-, 3-, 6-, and 12-month follow-up (from 33.0 cm(3) ± 25.1 [standard deviation] before treatment to 6.8 cm(3) ± 7.7 at 12-month follow-up). The mean percentage volume reduction at 1-, 3-, 6-, and 12-month follow-up was 28%, 57%, 63%, and 78%, respectively. The scores for symptoms and QOL were all significantly improved (P < .05) at follow-up, going from 45 ± 14 and 65 ± 41, respectively, before treatment to 0 and 100, respectively, at 12-month follow-up. No complications were reported during the periprocedural period or throughout follow-up. Most patients (41 of 45) were satisfied. Conclusion ST RFA may be an effective and safe alternative in the treatment of uterine leiomyomas. (©) RSNA, 2015 Online supplemental material is available for this article.
