title: [Uroflowmetry of males over 50 years old--analysis of the mass examination of the prostate].
abstract: The uroflowmetry of a total of 533 males over 50 years old, who had undergone a mass examination of the prostate in Tanno Town, Hokkaido Prefecture in 1982, and 1985, was studied. These subjects were divided into 4 groups, i.e., those 50 to 69 years old and those over 70 years old and those with and without prostatic hypertrophy by rectal palpation, the relationship between voided volume and flow rate was examined. Subjects without prostatic hypertrophy by rectal palpation in the older group showed markedly lower flow rate rate than the younger group and subjects with prostatic hypertrophy in the younger group had a lower flow rate than the older group. Thus, urinary disturbance in elderly men was supposed to occur due to aging changes such as benign prostatic hypertrophy and bladder neck contracture.
