Effects of protracted administration of estriol on the lower genito urinary tract in postmenopausal women

We investigated 80 postmenopausal women, 48 of whom (60%) agreed to undergo long-term treatment with estriol suppositories. All had symptoms of vaginal atrophy and urinary incontinence. Endometrial samples were taken after 8-10 years of therapy. Estriol had induced slight proliferative changes in the endometrium in 7 of 48 patients studied by endometrial sampling. 75% of the women reported significant subjective improvement of stress incontinence. Estriol supplementation did not produce any significant change in urethral pressure, functional length, or cystometric parameters. However, a significant increase in pressure transmission ratio to the proximal urethra was noted after vaginal medication with estriol. Replacement therapy in post-menopausal women must take into account the patients perception of risks and benefits. The risk of estriol treatment is insignificant.
