  • Title: [Therapeutic effects of focused ultrasound on chronic cervicitis and the influencing factors].
    Author: Xiao YB, Sun LJ.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 2007 Jan; 42(1):14-7. PubMed ID: 17331414.
    Abstract:
    OBJECTIVE: To explore the therapeutic effect of focused ultrasound (FU) on chronic cervicitis unitarily and its influential factors. METHODS: Three hundred and thirteen patients of chronic cervicitis were treated with the device of CZF model focused ultrasound. The therapeutic effects in 300 cases with complete records, as well as the relationship between the diameter of cervical erosion and the exposure time to FU were analyzed. RESULTS: The effective rates of FU in treatment of chronic cervicitis unitarily were 100.0% (53/53), 95.2% (120/126) and 91.7% (111/121), respectively, for mild, moderate and severe cases. The overall effective rate was 94.7% (284/300). With other parameters of FU unchanged, the exposure time to FU showed an exponential relationship with the diameter of erosion, and the regression equation was D = 31.71e(0.4808t) (R(2) = 0.9966). CONCLUSIONS: The controllability and achievement ratio of FU to treat cervical erosion could be enhanced when exposure time and manners were fully considered based on the diameter and type of cervical erosion. A satisfactory therapeutic efficacy could be achieved with FU to treat cervical erosion unitarily.
