目的探讨单次聚焦超声治疗慢性宫颈炎的效果及其影响因素。方法采用 CZF 型聚焦超声治疗仪,对313例慢性宫颈炎患者,行聚焦超声单次治疗,对其中有完整记录的300例患者(轻度53例、中度126例、重度121例)的治疗效果及影响疗效的因素进行分析。结果聚焦超声单次治疗轻、中、重度宫颈糜烂的有效率分别为100.0%(53/53)、95.2%(120/126)、91.7%(111/121),总有效率为94.7%(284/300)。在其他参数不变的情况下,糜烂面直径与辐照时间呈指数关系。结论聚焦超声单次治疗慢性宫颈炎临床效果显著;根据糜烂面积和不同组织声能量沉积的差异决定辐照时间,可提高治疗过程的可控性及单次治疗的成功率。 Objective To investigate the effect of single-focus ultrasound on chronic cervicitis and its influencing factors. Methods A total of 313 patients with chronic cervicitis were treated with focused ultrasound and CZF focused ultrasound was used to treat 300 cases of patients with chronic cervicitis (mild 53, moderate 126, severe 121) Effects and factors that affect the efficacy analysis. Results The effective rate of focused ultrasound in treatment of mild, moderate and severe cervical erosion was 100.0% (53/53), 95.2% (120/126) and 91.7% (111/121), respectively. The total effective rate was 94.7% (284) / 300). In the case of other parameters unchanged, the erosion surface diameter and the irradiation time is exponential. Conclusions Focused ultrasound treatment of chronic cervicitis has obvious clinical effect. According to the difference of erosion area and different tissue acoustic energy deposition, the irradiation time can be improved, the controllability of the treatment process and the success rate of single treatment can be improved.
