Menstrual blood loss was measured by intravenous injection of radioactive iron (59Fe) and whole-body counting in 19 women complaining of menorrhagia due to dysfunctional bleeding. Fifteen patients were then treated by radiofrequency endometrial ablation, after which blood loss was re-measured. The majority of the patients were bleeding excessively before treatment (mean 281 (SD 156) ml per cycle averaged over two cycles, range 49-665 ml, n = 19). In the 15 treated patients, average blood loss was reduced to 52 (SD 39) ml per cycle and the mean reduction in blood loss was highly significant (P < 0.001). These quantitative data correlate well with the patients' subjective reports.
通过静脉注射放射性铁（59Fe）并进行全身计数，对19名因功能失调性出血而月经过多的女性进行了月经量测量。然后对其中15名患者进行了射频子宫内膜切除术，术后再次测量了失血量。大多数患者在治疗前出血过多（两个周期平均每个周期281（标准差156）毫升，范围49 - 665毫升，n = 19）。在接受治疗的15名患者中，平均失血量降至每个周期52（标准差39）毫升，失血量的平均减少具有高度显著性（P < 0.001）。这些定量数据与患者的主观报告相关性良好。
