Abstract

OBJECTIVE
To compare the clinical effectiveness of transvaginal radiofrequency myolysis of the patients with leiomyomas and the patients with adenomyosis which have similar clinical symptoms.
METHODS
From May 2005 to May 2006 at Eulji university hospital, 108 women who were diagnosed of leiomyoma and adenomyosis had undergone transvaginal radiofrequency myolysis. Before and after the procedure size, number of uterine myomas, location and the volume of the leiomyomas and adenomyosis were measured by ultrasound. And on every visit after the procedure improvement of the symptom was checked by questionnaire of the symptom and life quality. Using Wilcoxon signed ranked test, the statistical significance was proved and the P value lower than 0.05 was judged to be significant.
RESULTS
76 women with leiomyoma who had undergone transvaginal radiofrequency myolysis, were followed up 1 month, 3 months, 6 months and 9 months after the procedure. The average maximal diameter of the myoma was decreased by 14.6%, 23.3%, 30.6%, 33.6% respectively, and the average volume was decreased by 35.7%, 53.3%, 67.3%, 72.2% respectively. 32 women with adenomyosis who had undergone transvaginal radiofrequency myolysis were followed up, at the same period after the procedure. The average maximal diameter of the adenomyosis was decreased by 8.9%, 13.6%, 14.6%, 11.9% respectively, and the average volume was decreased by 22.6%, 30.0%, 32.3%, 28.4% respectively. Before and after the procedure the symptom score was 62.3, 52.2, 40.6, 32.6, 28.6 respectively, and the quality of life score was 68.9, 78.1, 82.9, 85.7, 87.3 respectively in the leiomyoma group. In the adenomyosis group, before and after the procedure the symptom score was 77.7, 37.6, 30.6, 54.4, 67.5 respectively, and the quality of life score was 48.1, 76.5, 85.5, 66.5, 55.1 respectively.
CONCLUSION
Transvaginal radiofrequent myolysis had benefits in conserving the uterus, and was less invasive, and had great effect on the reducing the size of the leiomyoma and improving the symptoms, and also returning to normal life pattern was earlier. But in women with adenomyosis the symptoms were worsened after approximately 6 to 9 months after the procedure. Therefore additional research and follow-up is required and a strict criterion is needed.
