To evaluate the clinical efficacy of the novel Heat-Balance Technique (HB type) in Ultrasound-Guided Percutaneous Microwave Ablation for Uterine Fibroids (PMWA). According to the inclusion and exclusion criteria, 40 patients who underwent PMWA between June 2022 and June 2024 were selected. These patients were divided into two groups based on the specific surgical technique: one using the conventional technique and the other using a novel PMWA (HB-type). Relevant clinical data of the patients were retrospectively analyzed, and all patients were followed up postoperatively to assess the clinical efficacy of the two groups. All cases achieved effective ablation. Among them, 15 cases (93.75 %) in the HB-type group and 14 cases (87.5 %) in the conventional ablation group achieved marked efficacy, with no significant statistical difference between the two groups. Both modalities significantly improved patients' clinical symptoms (p < 0.001). The HB-type group showed significantly shorter surgical duration (8 [6-12] min vs. 25 [20-30] min; p < 0.001) and fewer antenna placements (1 [1,2] vs. 5 [3,5]; p < 0.001) than the conventional group. The HB-type technique in PMWA achieves comparable ablation effects and clinical efficacy to conventional ablation methods for uterine fibroids, while offering distinct advantages: shortened surgical duration, reduced number of antenna placements, and lowered the complication rates.
