    Article - En anglais


    We determined the occurrence of and risk factors for acute urinary retention in the community setting.

    Materials and Methods 

    A cohort of 2,115 men 40 to 79 years old was randomly selected from an enumeration of the Olmsted County, Minnesota population (55% response rate).

    Participants completed a previously validated baseline questionnaire that assessed symptom severity, and voided into a portable urometer to measure peak urinary flow rates.

    A 25% random subsample underwent transrectal sonographic imaging of the prostate to determine prostate volume.

    Followup was performed through a retrospective review of community medical records to determine the occurrence of acute urinary retention in the subsequent 4 years.


    During the 8,344 person-years of followup 57 men had a first episode of acute urinary retention (incidence 6.8/1,000 person-years, 95% confidence interval [CI] 5.2,8.9).

    Among men with no to mild symptoms (American Urological Association symptom index score 7 or less) the incidence of acute urinary retention increased from 2.6/1,000 person-years among men 40 to 49 years old to 9.3/1,000 person-years among men 70 to 79 years old.

    By contrast, rates increased from 3.0/1,000 person-years for men 40 to 49 years old to 34.7/1,000 person-years among men 70 to 79 years old among men with moderate to severe symptoms (American Urological Association symptom index score greater than 7). (...)
