Objective-To evaluate lower urinary tract symptoms in pre- and perimenopausal women. Method-Four hundred seventy-one women between 40 and 59 years of age with perimenopausal complaints attending our menopause clinic were evaluated for lower urinary tract symptoms by using the International Prostate Symptom Score questionnaire. The women were categorized by subgroups as being in premenopause, early menopause (1-<5 years' duration) and late menopause ( greater than or equal to5 years' duration), and by decade. Statistical evaluations were done by impaired t test, one-way ANOVA, and simple and multiple regression analyses. Results-The premenopausal women in their forties had more severe lower urinary tract symptoms when compared with early and late menopausal women. In comparisons the nocturia score tended to rise with age. Conclusion-Lower urinary tract symptoms appear to be affected by both age and the duration of menopause in women in their forties and fifties, and this observation might be taken into consideration while evaluating this age group for lower urinary tract symptoms.
