"Quality of life" assessment of urination in elderly Japanese men and women with some medical problems using International Prostate Symptom Score and King's Health Questionnaire.

Abstract

To investigate the relationships among lower urinary tract symptoms (LUTS), satisfaction at urination, and quality of life (QoL) in elderly Japanese men and women, who attended physicians for their medical problems. A total of 437 Japanese men and 196 women, aged 50 or older, responded to a questionnaire, which included seven questions regarding urination, one question about bothersomeness (QoL index) from the International Prostate Symptom Score (IPSS), two questions about frequency of urinary incontinence and 16 questions from the King's Health Questionnaire (KHQ). Of 401 patients who completed the IPSS and KHQ questionnaires, 235 (72.3%) men and 85 (64.7%) women had moderate to severe LUTS. In both genders, LUTS severity was significantly correlated with satisfaction status and KHQ-QoL domain scores. Satisfaction status also correlated with KHQ-QoL scores. Thirty-eight (13.5%) men and 27 (22.7%) women had frequent incontinence episodes. When excluding the patients with frequent incontinence episodes, KHQ-QoL scores of severe LUTS decreased in the domains of role, physical and social limitations, personal relationships and sleep/energy in women alone. Urination problems and related QoL status could be easily assessed by IPSS and QoL index in the elderly. Urinary incontinence appeared to be more associated with QoL in elderly women. The KHQ may be useful to assess the detailed urination-related QoL status of elderly men and women with LUTS or urinary incontinence.
