Laparoscopic coagulation of uterine myomas with the use of a unipolar electrode.

The aim of this study was to evaluate the effectiveness of a laparoscopic myolysis with the use of a unipolar electrode. Forty-six patients, 25 to 52 years old with symptomatic myomas (menometrorrhagia or/and pelvic pain) were included in the study. A transvaginal ultrasound showed 1 or 2 intramural or/and subserosal leiomyomata of 1 to 4.5 cm in diameter. Patients were selected to undergo a laparoscopic coagulation of myomas. Subsequently, they were followed-up 6 months after the treatment. Symptoms reduction and myoma size reduction were evaluated. In addition, all the patients underwent transvaginal Doppler ultrasounds to assess the blood flow in the uterine arteries. In the study group, the disappearance of myomas was observed in 52.2% of patients 6 months after the therapy. In other patients, the mean myoma shrinkage amounted to 76%. The myoma-volume reduction was correlated with an increase in the resistance index (P=0.02) and the pulsatility index (P=0.11) of the right and left uterine arteries.
