To investigate the impact of global aging on the trends in the age of hospitalized patients with a urological cancer diagnosis. We retrospectively evaluated a cumulative total of 10 652 cases of referred patients (n=6637) with a urological disease who were hospitalized in our institution between January 2005 and December 2021. We compared age and the proportion of patients aged ≥80 years among patients who were hospitalized in the urological ward between the period of 2005-2013 and that of 2014-2021. We identified 8168 hospitalized patients with urological cancer. The median age was significantly increased in patients with urological cancer between the periods of 2005-2013 and 2014-2021. The proportion of hospitalized patients with urological cancer aged ≥80 years was significantly increased between the periods of 2005-2013 (9.3%) and 2014-2021 (13.8%). The median ages of the patients with urothelial cancer (UC) and renal cell carcinoma (RCC), but not the median age of those with prostate cancer (PC), were significantly increased between the study periods. The proportion of hospitalized patients with UC, but not the proportions of those with PC and RCC, aged ≥80 years was significantly increased between the study periods. The age of patients with urological cancer who were hospitalized in the urological ward and the proportion of patients with UC aged ≥80 years significantly increased over the entire study period.
