目的探讨聚焦超声治疗宫颈上皮内低度瘤样病变(CINⅠ)的临床疗效。方法对经细胞学、阴道镜定位活检,病理检查明确诊断为CINⅠ级的30例患者行高强度聚焦超声治疗,于治疗后3、6、12个月行液基细胞学及阴道镜检查。结果术后3、6、12个月治愈率分别为90%、93.3%、100%,所有病例宫颈恢复正常形态。结论聚焦超声能有效地治疗宫颈上皮内低度瘤样病变,并发症少。 Objective To investigate the clinical effect of focused ultrasound in the treatment of cervical intraepithelial neoplasia (CINⅠ). Methods Thirty patients with clinically diagnosed as CIN Ⅰ by cytology and colposcopy were examined by high intensity focused ultrasound and liquid-based cytology and colposcopy at 3, 6 and 12 months after treatment. Results The cure rates at 3, 6 and 12 months after operation were 90%, 93.3% and 100%, respectively. All cases returned to normal form. Conclusions Focused ultrasound can effectively treat low-grade cervical intraepithelial neoplasia with few complications.
