This is the first facility-level comparative study conducted for TFA.Patients and Methods: The study enrolled 88 patients from 4 centers equally divided among the two cohorts. The TFA arm consisted of 44 women who had enrolled in the SONATA Pivotal IDE trial, whereas the myomectomy arm included 44 patients who were identified through retrospective case-matching to the enrolled SONATA patients at the same 4 centers.Results: TFA had a significantly lower mean operating room duration (90 minutes) and length of stay (5.2 hours) than myomectomy (143 minutes and 45.8 hours, respectively). The average total mean facility costs for TFA procedure ($7,563) were significantly lower than those associated with myomectomy ($11,425; p=0.002). TFA mean facility costs were also compared with other stratifications of myomectomy (inpatient or outpatient and surgical route). TFA facility costs were significantly lower than that associated with inpatient, abdominal, or laparoscopic myomectomy (all p< 0.001).Conclusion: TFA using the Sonata system has a significantly shorter operating room time and length of stay than myomectomy for the treatment of symptomatic uterine fibroids. All procedure, anesthesia, laboratory, pathology, and pharmacy costs were significantly higher for myomectomy as compared to TFA. TFA was also associated with significantly lower facility procedure-related costs compared to myomectomy, including inpatient, abdominal, or laparoscopic myomectomy.Keywords: uterine fibroids, Sonata, transcervical ablation, uterine preserving, cost, radiofrequency ablation
