Lower urinary tract symptoms (LUTS) and urinary incontinence (UI) are common in the Canadian population, researchers report.

 

A team led by Sender Herschorn, MD, of the Sunnybrook Health Science Centre in Toronto, analyzed data gathered from 1,000 adults (518 women with a mean age of 45 years and 482 men with a mean age of 44 years) who responded to a telephone survey.

Subjects were questioned about urinary symptoms and daytime and nighttime voids.

Of these respondents, 57% of women and 43% of men reported one or more LUTS, with nocturia the most common symptom (reported by 36% of respondents). Overactive bladder symptoms (urgency, with or without urgency UI, usually with frequency and nocturia) were reported by 14.7% of women and 13.1% of men, according to a report in BJU International (2007; published online ahead of print). UI was reported by 28.8% of women, of whom 68% had stress UI (SUI), 21% had mixed UI (MUI), and 11% had urgency UI (UUI).

 

Of the 5.4% of men with UI, 27% had SUI, 15% had MUI, and 58% had UUI. Overall the prevalence of LUTS rose with age.

 

The authors noted that the prevalence of LUTS and UI in Canada is similar to that observed in other countries.
