Abstract
BACKGROUND: Current epidemiological patterns of adverse events of clinical BPH remain unclear. We investigated trends in acute urinary retention (AUR) associated with BPH in a large, population-based cohort. METHODS: We utilized the California Office of Statewide Health Planning and Development Database to examine 3 724 016 emergency room (ER) visits in California among men aged 50 years from 2007 to 2010. Outcomes included AUR for which BPH was the primary diagnosis, AUR for which BPH was a secondary diagnosis and urethral catheterization for AUR. We generated adjusted odds ratios (ORadj) using multivariate logistic regression to determine longitudinal trends. RESULTS: A total of 17 023 men presented with a diagnosis of BPH-associated AUR, the unadjusted incidence of which increased from 4.00 per 1000 ER visits in 2007 to 5.23 per 1000 ER visits in 2010 (P<0.001). In adjusted analyses, primary AUR (ORadj=1.25; 95% confidence interval (CI), 1.19-1.32; P<0.001) and secondary AUR (ORadj=1.80; 95% CI, 1.62-2.00; P<0.001) increased 25% and 80%, respectively. Urethral catheterization for primary (ORadj=1.30; 95% CI, 1.22-1.39; P<0.001) and secondary (ORadj=1.82; 95% CI, 1.57-2.11; P<0.001) AUR increased 30% and 82%, respectively. Asian race (P<0.001), Hispanic race (P<0.001) and commercial insurance (P<0.001) were associated with significantly increased risks of AUR and urethral catheterization. CONCLUSIONS: Between 2007 and 2010, the observed incidence of BPH-associated AUR increased substantially in a large and ethnically diverse male population of the United States.
