To trend the impact of lower urinary tract symptoms attributed to benign prostatic hyperplasia (LUTS/BPH) on a global scale. LUTS/BPH is a globally prevalent chronic disease causing significant morbidity and quality of life impairment.
Current understanding of trends in LUTS/BPH is limited to studies predominantly focused on North America and Europe. Using the Global Burden of Disease (GBD) database, we sought to trend this impact from a more global viewpoint.
Using the GBD database, worldwide data aggregated from registries and health systems from 1990-2017 were filtered for LUTS/BPH diagnoses. Calculation of years lived with disease (YLD) were compared with other urological disease. YLD were calculated by a standardized method using assigned disability weights. GBD-defined socio-demographic index was used to assess impact of LUTS/BPH by global SDI quintile.
GBD data over the 1990-2017 study period are summarized and global numbers and trends noted with other urologic disease for comparison. 2,427,334 YLDs were attributed to BPH in 2017 alone, almost 3 times greater than the next highest urologic disease, prostate cancer (843,227 YLDs). When stratified by SDI quintiles, a much lower impact of BPH was found in the bottom three quintiles, despite this subset representing 66.9% of 2017 world population.
LUTS/BPH exerts a rapidly rising human burden far exceeding other urologic disease. As the population ages and lower SDI men enjoy increased life expectancy and decreased competing mortalities, a continually accelerating wave of LUTS/BPH can be forecast. These epidemiologic trends have serious implications for the future allocation of resources and the global urologic workforce.
