Impact of previously unrecognized benign prostatic hyperplasia on the daily activities of middle-aged and elderly men.

Abstract

To assess the importance of benign prostatic hyperplasia on activities of daily living, a cross-sectional survey of 1627 men aged 40-79 years (representing a 65% response rate) registered with two health centres in central Scotland was carried out, using a urinary symptom questionnaire and uroflowmetry to identify men more likely to have benign prostatic hyperplasia. The condition was defined as a prostate gland of more than 20 g in the presence of symptoms of urinary dysfunction and/or a peak flow rate of less than 15 ml s-1, without evidence of malignancy. Transrectal ultrasonography was used to measure the volume (and by inference weight) of prostate glands. A total of 410 men satisfied the criteria for benign prostatic hyperplasia. Overall, 51% of men with benign prostatic hyperplasia reported interference with at least one of a number of selected activities of daily living as a result of urinary dysfunction, compared with 28% of men who did not have this condition. In 17% of men of working age (40-64 years) with benign prostatic hyperplasia, this interference occurred most or all of the time for at least one activity of daily living compared with only 3% of men in the same age group who did not have this condition. If the criteria of unmet need for treatment of benign prostatic hyperplasia constitutes interference by urinary dysfunction most or all of the time in at least one activity of daily living, then the findings of this survey suggest that a substantial number of middle aged and elderly men living in the United Kingdom may be in need of assessment and treatment for this condition.
