Estrogen therapy in older patients with recurrent urinary tract infections: A review

Although urogenital complaints, such as recurrent lower urinary tract infections (UTI), and dysuria, are commonly encountered in elderly women, few women have participated in randomized studies of estrogen therapy for this condition. This is a paradox in view of the often cited beneficial effect of estrogen in reducing the incidence of UTI. Present evidence documents that in postmenopausal women, hormone replacement therapy using topical estrogen normalizes the vaginal flora and greatly reduces the risk of vaginal atrophy. Similarly, vaginal estrogen administration seems to be effective for preventing recurrent urinary tract infections (UTI).
