title: [Clinical application of GnRHa before uterine myomectomy: report of 20 cases].
abstract: OBJECTIVE
  To study the clinical application of GnRHa prior to uterine myomectomy and its effect on the clinical outcome of pregnancy.
  
  
  METHODS
  A retrospective review of the medical records in 20 cases of uterine myomectomy over a period of 6 years was performed. The changes of uterus and myoma volumes in response to preoperative GnRHa was observed, and the rate of relapse in the follow-up, time of impregnation, spontaneous abortion after the impregnation, time of delivery after the operation and the aura threatening uterine rupture, and uterine rupture during the delivery were assessed.
  
  
  RESULTS
  Application of GnRHa produced significant improvement in the clinical symptoms and resulted in obviously reduced volumes of the uterus and myoma. The myoma volume reduction was close to 50% in these cases, and relapse occurred in only 1 case. No spontaneous abortion was found after GnRHa application. The average time of pregnancy was 34+/-3.5 weeks, and aura for uterine rupture was found in 1 case at 33 weeks of pregnancy after GnRHa application.
  
  
  CONCLUSIONS
  Application of GnRHa can correct anemia, decrease the relapse rate of myoma, reduce uterus and myoma volumes, to make possible smaller incision for uterine myomectomy that leaves smaller scar in the uterus and decrease intraoperative bleeding, also relieving endometrial injuries to promote the conditions for impregnation and minimize the risks of uterine rupture and total hysterectomy for the benefit of normal delivery.
