Objectives:
To study parameters of the micturition pattern in postmenopausal women and the effect of an oral continuously combined HRT-regimen.
Methods:
Hormone therapy consisted of 2 mg 17 beta-oestradiol in combination with either 2.5, 5, 10 or 15 mg dydrogesterone, orally once a day. The baseline assessment was done just before starting hormone replacement therapy, the second assessment took place after 6 months of hormone therapy. Data were collected using a standardized questionnaire and focused on diurnal urinary frequency, nocturnal urinary frequency and urinary incontinence as parameters of the micturition pattern. Furthermore, bacteriuria was assessed.
Results:
One hundred and two women entered the study and 95 women completed 6 months of hormone replacement therapy. Urinary incontinence was reported by 44.1% of the women, in 19.6% of the women it occurred more than twice a week. Both diurnal frequency and nocturnal frequency was reported by 28.4% of the women. For women with frequency or nocturia, the number of voids significantly decreased after 6 months hormone replacement therapy. Nocturia disappeared in 65.4% of the women after treatment and 23.3% reported to be cured of their urinary incontinence. Bacteriuria was present in the same seven women before and after hormone treatment. Dydrogesterone dose did not influence treatment outcomes.
Conclusions:
Postmenopausal women report improvement on urinary incontinence and nocturia after 6 months of a continuously combined hormone replacement therapy regimen. The improvement was most outspoken with regard to nocturia. Bacteriuria was not influenced. Different doses of dydrogesterone did not effect these findings.
