OBJECTIVE To compare the effectiveness of two second-generation ablation techniques, bipolar radio-frequency impedance-controlled endometrial ablation (NovaSure) and balloon ablation (ThermaChoice), in the treatment of menorrhagia. DESIGN Double-blind, randomised, controlled trial. SETTING A large teaching hospital with 500 beds in The Netherlands. (More)
OBJECTIVE We have previously reported that NovaSure was more effective than balloon ablation at 12 months follow up in the treatment of menorrhagia. In this paper, we report the 5-year outcome of this study. The objective was to evaluate amenorrhoea rates, hysterectomy rate, and quality of life associated with the bipolar impedance-controlled endometrial(More)
OBJECTIVE To compare maternal and perinatal complications in triplet and twin pregnancies. STUDY DESIGN Case-controlled study in the setting of a University Hospital. Each pregnancy of a consecutive series of 40 triplet pregnancies of 20 weeks or more was matched for parity and maternal age with two sets of twins delivered in the same year. Primary end(More)
OBJECTIVE To assess the accuracy of our recently developed prediction model in a prospective validation study to predict the outcome of intrauterine insemination (IUI). DESIGN Descriptive prospective validation study. SETTING Seven fertility centers in the Netherlands. PATIENT(S) Couples treated with IUI of whom the female partner had a regular cycle.(More)
The Chlamydia antibody titre (CAT) is a test used to identify subfertile couples at increased risk for tubal pathology. The usefulness of the routine performance of CAT was evaluated in a multicentre prospective cohort study, in women without regular ovulation. Consecutive couples presenting with subfertility due to an irregular menstrual cycle or(More)
Objective: A bipolar radio-frequency impedance-controlled endometrial ablation system is more effective than balloon ablation in the treatment of dysfunctional uterine bleeding. The aim of the present study was to compare the costs of both treatments, and to perform a cost-effectiveness analysis. Study design: An economic evaluation was set up alongside a(More)
BACKGROUND Pregnancy rates among infertile women have been reported to increase after hysterosalpingography, but it is unclear whether the type of contrast medium used (oil-based or water-soluble contrast) influences this potential therapeutic effect. METHODS We performed a multicenter, randomized trial in 27 hospitals in the Netherlands in which(More)
OBJECTIVE To evaluate the capacity of the postcoital test (PCT) to predict spontaneous pregnancy in a large cohort study of subfertile couples. DESIGN Prospective study. SETTING Department of reproductive medicine of 38 hospitals in the Netherlands. PATIENT(S) Between January 2002 and February 2004, we prospectively included consecutive subfertile(More)
OBJECTIVE To investigate patient preferences for endometrial ablation and a levonorgestrel-releasing intrauterine device (IUD) as alternatives to hysterectomy in the treatment of dysfunctional uterine bleeding. DESIGN Comparative study based on structured interviews. SETTING A large teaching hospital with 500 beds in the Netherlands. PATIENT(S)(More)
