In the management of menorrhagia, endometrial ablation techniques or intra-uterine progesterone-containing devices are employed when medical therapy fails. We postulated that the insertion of a Mirena IUS at the time of a TCRE would improve upon the success rates found when either is user individually. In a small pilot study, we identified patients who had both a TCRE and Mirena over a 26 month period. Those younger than 45, with a follow-up period of one year formed the final study group of 18. There were high rates of patient satisfaction, with a significant reduction in menstrual bleeding in the majority of patients. An amenorrhoea rate of 67% was achieved, which is significantly higher than the rates found with either TCRE or Mirena alone.
