Enlarged prostate: a landmark national survey of its prevalence and impact on US men and their partners.

This questionnaire-based survey evaluated the frequency and severity of lower urinary tract symptoms (LUTS) and the prevalence of enlarged prostate (EP) diagnosis and its impact on quality of life and spousal relationships among >1000 American men aged >50 years. A quarter of men suffered moderate to severe LUTS and 55% of those consulting a doctor had EP. EP negatively affected patient quality of life and caused relationship strain with spouses. These findings confirm that LUTS and EP are prevalent in the US population, affecting both patient and spouse, and may help in developing management strategies for EP.
