- Lower urinary tract symptoms are highly prevalent in older men, have been shown to affect men's quality of life, and may be associated with more serious outcomes. To determine the prevalence of LUTS among men aged 50 years or older registered at family practice centers in Israel and to assess the effect of these complaints on different aspects of their life. In a random sample cohort of men aged 50 years and older, fluent in Hebrew, drawn from those registered in four family clinics in Israel, patients identified with LUTS were interviewed by phone using a structured questionnaire. The prevalence of LUTS in our study was 21%. Less than a third of these patients had low severity LUTS (28%), 59% were rated moderate, and 13% had severe symptoms. Age had a positive correlation with the severity of LUTS, and increasing severity of symptoms had a negative effect on the daily function and quality of life of patients. Our community-based study shows that LUTS is a common finding among men above the age of 50 (21%) and has a significant negative effect on their quality of life and daily function. Knowledge of these data should make primary care physicians more aware of this common problem and thus improve the treatment and quality of life of these patients by better identification and prompt treatment.
