Fibromyomas and uterine activity

Intra-uterine pressure was recorded with a triple-channelled microtransducer catheter in women with fibromyomas prior to hysterectomy or myomectomy and in women due to undergo hysterectomy because of other gynecological disorders. In most of the patients with myomas the uterine activity differed from that in the women without myomas and from findings in previous studies on uterine activity in healthy subjects. Thus, small and irregular contractions were frequently seen in the pressure recordings from the receptors placed in the vicinity of myomas. In women with dysmenorrhea secondary to the development of myomas, increased uterine activity was registered. It is concluded that myomas may have a clinically significant effect on uterine activity.
