Objectives: To compare the impact of the type of urinary incontinence on women's quality of life. Methods: A retrospective evaluation was conducted on the medical records of 77 incontinent women who underwent physical therapy treatment between February 2005 and October 2006. Based on the urodynamic test data, the women were classified into three groups: stress urinary incontinence (SUI), overactive bladder (OB) and mixed urinary incontinence (MUI). The subjects' history was taken, the women provided demographic data and they answered the King's Health Questionnaire, which is a specific questionnaire for assessing the quality of life among individuals with urinary incontinence. Results: Most of the patients (44%) had MUI. The patients affected by OB were significantly older than the patients in the other groups. The negative impact of incontinence on quality of life (General Health Perception domain) and lifestyle was significantly greater among the women affected by MUI than among the patients in the other groups. Conclusion: This study indicated that the negative impact of incontinence on quality of life was greater among patients with MUI.Key words: urinary incontinence; quality of life; women's health.
