(Purpose) We invastigated the prevalence of lower urinary tract symptoms and the effect of subjective urinary symptoms on quality of life (QOL) in elderly males examined prostate cancer screening in total health check from April 1996 to March 1997.
(Patients and methods) A total of 922 eligible examineers 50 to 70 years old completed a questionaire with questions worded similarly to those of the international prostate symptom score (I-PSS) and AUA Impact index score and so on.
(Results) The prevalence of moderate to severe symptoms was 19.6%, which increased with age. I-PSS was well correlated aging but not prostate size. The most prevalent symptoms were nocturia (61.1%), frequency (50.0%) and weak stream (47.7%). There was good correlation between symptom severity and QOL and AUA Impact index scores. While QOL was correlated with obstructive and irritative symptom scores, wish for treatment was associated mainly with irritative symptoms by multiple regrresion analyses. However, some examineers (15.5%, 28/181), who had moderate to severe symptoms, did not feel a decrease of QOL in daily life.
(Conclusions) A large percentage of elderly men 50 years old or older experienced symptoms. However, subjective urinary symptoms did not always correlate with QOL in some individuals. We should independently consider not only symptom severity but also QOL and AUA Impact index score in clinical dicision making.
