Prevalence of urinary incontinence in middle-aged women

An anonymous questionnaire was used to interview 946 premenopausal women (age 29-52 years), previously either hysterectomized or laparoscopically sterilized, concerning disorders of the urinary tract. Of the 750 (79.3%) women that responded, 307 (40.9%) admitted to some degree of urinary disorder. The prevalence of urinary disorders was 170/415 (40.9%) for the women with a previous supravaginal or total hysterectomy and 137/335 (40.8%) for the women in the sterilization group. Of the responding women 85 (11.3%) experienced a urinary loss sufficient to necessitate the wearing of a sanitary napkin or change of underclothing several times a day.
