ABSTRACT
Multiple factors have resulted in an increase in the median age of the world’s population. A decrease in fertility rate as well as an increase in the average lifespan, in part due to advances in public health interventions, will result in an increase in both the number and the proportion of older adults in the years to come.1 The US population is also aging, and by the year 2030 it is estimated that those aged 65 years or older will make up almost 20% of the nation’s population. In the year 2000, there were 13.1 million men over the age of 65 and 1.2 million men over the age of 85 in the US. It is estimated that by the year 2050, there will be 29 million men over the age of 65 and 7 million men over the age of 85 in the US (Fig. 25.1).2 As the population ages, we will witness a concomitant increase in the prevalence of chronic diseases and comorbidities. Urologic problems seen with increased frequency in aging men are benign prostatic hyperplasia (BPH), bladder outlet obstruction (BOO), and overactive bladder (OAB). The focus of this chapter is discussion of the prevalence and impact of OAB in men, potential etiologies of OAB and lower urinary tract symptoms (LUTS) in men, and treatment options for refractory OAB. The evaluation and treatment of BPH is beyond the scope of this chapter.
