european studies have revealed that the overall prevalence of lower urinary tract symptoms (LUTS) suggestive of the incidence of BPH is 10.3% in men older than 45, which increases to 24% at age 80 (1)
prevalence of BPH rises markedly with age
autopsy studies have estimated that evidence of BPH is present in
40% of men in their 50s
70% in their 60s
88% in their 80s (1)
there is evidence that the incidence of acute urinary retention secondary to BPH is increasing (2)
according to the result fromone Chinese national cross-sectional survey, the adjusted odds ratio (OR) for the prevalence of LUTS/BPH is (3):
1.50 (95% confidenceintervals (CI) 1.20 to 1.87) in men aged 60 to 69 years
2.09 (95% CI 1.58 to 2.78) in men aged more than 70 years comparedto men aged less than 60 years
