Epidemiology of urologic diseases in the aging population.

Abstract

Japan is an aging society. In general, an elderly population has urological diseases. Therefore, to understand the epidemiology of urological diseases is clinically very important. In a 15-year-longitudinal community-based study of Japanese men, prostate volume in- creased and lower urinary tract symptoms deteriorated. Many elderly Japanese females have pollakisuria. The 2015 cancer statistics suggest that the most common cancer in Japanese males is prostate cancer. Urothelial carcinoma develops in a relatively elderly population. The erectile function of aging Japanese men demonstrated an age-related decline in the community-based study, with erectile rigidity declining over a 15-year period.
