A systematic review of estrogens for recurrent urinary tract infections: third report of the hormones and urogenital therapy (HUT) committee.

Our objective was to apply a meta-analysis to the available data to evaluate the effect of estrogen supplementation in the prevention of recurrent urinary tract infections in postmenopausal women. The literature review incorporated articles based on a search of Excerpta Medica, Medline, Science Citation Index and a manual search of commonly read journals in the fields of urology, gynecology, gerontology and primary healthcare, from January 1969 to December 1998. The search was not limited to English-language publications. Inclusion criteria were peer-reviewed articles containing original data with a primary outcome of symptomatic urinary tract infections and an estrogen-treated group. Articles were categorized into randomized controlled trials, case-control studies and self-controlled series. Of the articles reviewed, five were randomized controlled trials, two were case-control studies and three were self-control series. Meta-analysis of data from 334 subjects revealed a significant benefit from estrogen over placebo (odds ratio = 2.51, 95% confidence interval = 1.48 4.25). The most convincing results were obtained using the vaginal route of administration. A variety of different estrogen preparations have been employed in the few published reports, making comparison of the data difficult. However, vaginal administration seems to be effective in the prevention of recurrent urinary tract infections in postmenopausal women.[1]
