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.
