RESUMO
OBJECTIVE: To evaluate the clinical efficacy of radiofrequency myolysis which is new developed uterine preserving management of myoma. METHODS: 17 patinets (27 myomas) who done radiofrequency myolysis between Oct. 2004-Dec. 2004 were participated this study. Preoperatively, Hemoglobin and subjective symptoms were checked and size of myoma was checked using ultrasonogram or computed tomogram (CT). Radiofrequency was applied to myoma for 10 to 40 minutes per one. Follow up sonogram or CT were done 7 days, 1 month, 2 month and 3 month after myolysis. RESULTS: Average age of patients was 42.7+/-8.6 (yr) and average size of myoma was 4.9+/-2.3 cm. We followed 27 nodules. After 3 months, reduction of volume was observed 65%, from 30% to 94%. 3 nodule, which was followed only 2 months, reduced by 46%. About subjective symptoms, 80% reduction was reported after 3 months (50-100%). Menorrhagia reduced 91% in average and pressure symptoms reduced 71% in average. No severe complication like bowel injury, bladder injury, infection and pulomonary embolism was not observed. Serious vaginal bleeding was reported for 3 patients, and their hemoglobin decreased from 10.8 mg/dL preoperatively to 8.7 mg/dL postopertively. CONCLUSION: Radiofrequency myolysis decreased myoma 65% in average. No serious complication were reported.
