Impact on quality of life of different lower urinary tract symptoms in men measured by means of the SF 36 questionnaire

Abstract

To describe how different lower urinary tract symptoms (LUTS) affect the quality of life (QOL) in men. The study included 1008 men aged 40-80 years living in the community of Surahammar, Sweden who had answered a questionnaire concerning stress incontinence, urgency and post-micturition dribbling 12 months earlier. The occurrence and severity/frequency of 12 specific LUTS were assessed using the Danish Prostatic Symptom Score questionnaire. QOL was evaluated using the Short Form 36 (SF-36) questionnaire. Post-micturition dribbling was the most frequently reported symptom (71%) and stress incontinence the least common (11%). Men who experienced urge, stress or "other incontinence" had lower mean scores for all of the eight dimensions measured by the SF-36 than men without such symptoms. Furthermore, men who experienced a moderate/severe degree of weak stream or nocturia reported a poorer QOL for all dimensions compared to men with a mild level of the same symptoms. QOL was found to decrease with increasing age. Men aged 66-80 years with "other incontinence" reported lower mean SF-36 scores for physical functioning, role physical, role emotional, social functioning and body pain than 40-65-year-old men. LUTS in men affect QOL dimensions differently. Storage symptoms appear to reduce QOL more than voiding and post-micturition symptoms. Urinary incontinence affected all eight of the dimensions evaluated. Elderly men with LUTS reported a lower QOL than younger men.
