CLINICIAN’S CORNER Management of Urinary Incontinence in Women Scientific Review Context Urinary incontinence is a common health problem among women that nega-
tively impacts quality of life. Therefore, it is important that primary care physicians have
an understanding of how to manage urinary incontinence effectively. Objective To review the most recent, high-quality evidence regarding the etiology
and management of urinary incontinence in women.
tary leakage of urine,1 is acommon health problem
Data Sources and Study Selection Searches of MEDLINE, EMBASE, The Coch- rane Library, and the ACP Journal Club were performed to identify English-language
articles published between 1998-2003 that focused on the etiology or treatment of uri-
nary incontinence in adult women. The references of each retrieved article were re-
viewed and an expert in the field was contacted to identify additional relevant articles. Data Extraction Using a combination of more than 80 search terms, we included
articles of etiology that were cohort studies, case-control studies, cross-sectional stud-
ies, or systematic reviews of cohort, case-control, and/or cross-sectional studies. Stud-
ies of treatment had to be randomized controlled trials or systematic reviews of ran-
domized controlled trials. The quality of each article was assessed independently by
each author and inclusion (n=66) was determined by consensus. Data Synthesis Multiple factors have been found to be associated with urinary in-
continence, some of which are amenable to modification. Factors associated with in-
continence include age, white race, higher educational attainment, pregnancy-
and overflow incontinence. Stress in-
related factors, gynecological factors, urological and gastrointestinal tract factors,
continence is involuntary leakage from
comorbid diseases, higher body mass index, medications, smoking, caffeine, and func-
tional impairment. There are several effective nonpharmacological treatments includ-
ing pelvic floor muscle training, electrical stimulation, bladder training, and promptedvoiding. Anticholinergic drugs are effective in the treatment of urge urinary inconti-
nence. Several surgical interventions are effective in the management of stress incon-
