Bladder cancer (BC) survival has shown no significant improvement. This study investigated the trends in the common causes of death among patients with BC to improve the management and survival of BC. The Surveillance, Epidemiology, and End Results (SEER) (1992–2018) database was utilized to get the data of BC patients. We presented the proportion of six common causes of death in BC patients. We calculated the annual incidence of death due to the six most common causes and analyzed temporal trends in mortality rates using joinpoint regression. The competitive risk model was utilized to analyze the risk factors for death of BC and other causes. 198037 BC patients were enrolled. BC was the most common cause of death (30.62%), followed by other cancers (22.22%), circulatory diseases (20.28%), non-disease causes (11.58%), other non-cancer diseases (8.29%), and respiratory diseases (7.01%). However, the proportion of cases dying from BC gradually decreased from 44.87% in 1992–1996 to 26.74% in 2012–2018. The proportion of deaths due to BC decreased gradually with survival time from diagnosis. Age-standardized temporal trends present an initial increase in BC-specific and other-cause mortality rates. Advanced stage and older age were the most influential risk factors for BC-specific and other-cause death, respectively. Although BC was still the leading cause of death, other causes, especially other cancers and circulatory diseases, gradually became more critical. The management of other comorbid conditions will be a crucial part of the treatment for BC patients, especially for those with prolonged survival and NMIBC tumors.
