Objectives: Our aim was to conduct a survey about urinary symptoms and to find out if questioning patients about symptoms is helpful for the GP to make medical decisions concerning prostate problems among middle-aged men.
Methods: Twelve hundred randomly chosen men aged 55--65 years from the general population in north-west Stockholm, Sweden were sent a questionnaire consisting of symptom questions focusing on prostate problems based on the International Prostate Symptom Score (I-PSS). A subset of 120 respondents were asked to answer the same questions again and to participate in a urological examination including urodynamics and ultrasonography. The main outcome measures were the prevalence of urinary symptoms and the relationship between the symptom score and objective measures.
Results: A response rate of 86% was obtained in the questionnaire study. Twenty-one per cent of the respondents stated that they had general problems related to urination. Among individual symptoms, post-void dribbling and a weak stream were most common. Among the men examined at the Urological Department, the average prostatic volume was found to be 40 cm(3). Three out of four were assessed to have infravesical obstruction. No correlation between subjective symptoms and objective measurements of either a statistical or clinical significance was found.
Conclusions: Urinary symptoms are common among middle-aged men. Further, an enlarged prostate and/or infravesical obstruction is often found in the ageing man. Information obtained by asking prostate-specific symptom questions cannot, however, serve as the foundation for the GP to find those men whose problems would be solved by actions directed at the prostate.
