ABSTRACT

OBJECTIVE: To evaluate the clinical results of radiofrequency (RF) myolysis on uterine myomas for 1 year after the procedure. METHODS: 56 women with symptomatic uterine myomas underwent RF myolysis at Chosun University hospital between January 2006 and December 2006. The study group designed by 22 women who were followed up for 1 year after the procedure. Preoperatively, by using ultrasonography, size, numbers, location and volume of uterine myomas were checked and hemoglobin and subjective symptoms were checked. 3 months, 6 months, 9months and 12months after the procedure, the size and volume of uterine myomas were measured by same examiner. And also the symptoms caused by uterine myomas were observed. RESULTS: The average age of the patients was 43.0 years. The average maximal diameter of uterine myoma was 5.7+/-1.9 cm, the average volume was 83.2+/-67.6 cm3, and the average hemoglobin was 11.5+/-2.0 mg/dL. 3 months, 6 months, 9 months and 12 months after the procedure, the average maximal diameters of the uterine myomas were decresed by 4.7+/-1.8 cm, 4.4+/-1.6 cm, 4.3+/-1.7 cm, 3.9+/-1.6 cm and the average volume was decreased by 49.5+/-46.5 cm3, 41.1+/-43.2 cm3, 40.5+/-43.7 cm3, 30.8+/-34.6 cm3 respectively, and the average hemoglobin was 11.8+/-1.8 mg/dL, 11.9+/-1.8 mg/dL, 12.1+/-1.7 mg/dL, 12.1+/-1.5 mg/dL. After the procedure, 81.3%, 84.8%, 87.0%, 86.4% of the group had improvement of the symptoms (dysmenorrhea, hypermenorrhea, pelvic pain) respectively. CONCLUSION: RF myolysis had effects on reduction of the size of uterine myomas and improvement of the symptoms. RF myolysis would be a useful alternative treatment of uterine myomas with preserving the uterus.
