PURPOSE:
To establish age-stratified normal values for prostate volume, serum total prostate-specific antigen (PSA) concentration, maximum urinary flow rate (Q (max)), micturition and postvoid residual urine volumes, IPSS, and quality of life. These community-derived values of healthy older men are necessary to correctly judge patients with lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH).
METHODS:
Analysis of LUTS/BPH-related determinants in community-dwelling men in the city of Herne, Germany after exclusion of subgroups with co-morbidities or co-medications with possible influence on the key items.
RESULTS:
The analysis is based on 1,763 participants. In these men aged 50-80 years, mean total prostate volume continuously increased from 24 to 38 cc and mean PSA concentration from 1.1 to 2.5 ng/ml. PSA concentration in men with a prostate volume
