Objective To study the effects of pretreatment with triptorelin on ute
rine fibroid before abdominal hysterectomy . Methods Fifteen premenopa
usal Chinese women with symptomatic uterine fibroids requiring hystere
ctomy were recruited in the study. All patients received monthly intra
muscular injections of 3.75 mg triptorelin for three months prior to a
bdominal hysterectomy . Results There was significant reduction in the
serum levels of oestradiol (68.6%), progesterone (95.6%) and luteiniz
ing hormone (73.9%) and in uterine (45.0%) and fibroid (68.0%) volumes
. The serum level of follicle-stimulating hormone and haemoglobin conc
entration were not significantly different. Conclusions Shrinkage of u
terine fibroids can be achieved in women who are rendered hypoestrogen
ic with monthly injections of triptorelin for three months. This treat
ment modality may be of value prior to hysterectomy or myomectomy espe
cially when the fibroid is large.
