Risk Factors for Overactive Bladder and Urinary Incontinence
|RISK FACTORS FOR OVERACTIVE BLADDER AND URINARY INCONTINENCE|
|Age||The prevalence of symptoms increases
significantly. In one study, incidence
rose from 3.4% of men between the
ages of 40 and 44, to 41.9% of men
75 years and older.
|Prevalence also increases with age. In
the same study, incidence increased
from 8.7% of women between the ages
of 40 and 44, to 31.3% of those
75 years and older.
|Multiple sclerosis, spinal cord injury, diabetes, Parkinson's disease, stroke, dementia, and impaired mobility may cause bladder symptoms.||Same for women.|
|Medications||Diuretics, antidepressants, alpha-agonists, beta-antagonists, sedatives, anti-cholinergics, and analgesics can all cause urinary tract symptoms.||Same for women.|
|N/A||Menopause has been associated with a decrease in urethralmucosa vascularity and thickness, as a result of diminished estrogen production.|
|Pelvic surgery||Incontinence has been seen in men following surgical treatment for prostate cancer.||Hysterectomy may increase a woman's risk of incontinence.|
|N/A||Pregnancy and vaginal childbirth increase the risk of incontinence.
Post-childbirth incontinence has been associated with the use of forceps, vacuum extraction, episiotomy, and pudendal anesthesia.
|BPH, and prostatic obstruction secondary to BPH. Prostate cancer may also cause symptoms.||N/A|
|Race||No studies have been done in men comparing race and incidence of OAB.||White women appear to be at higher risk for incontinence. Compared with black women, they may have a shorter urethra, weaker pelvic floor muscles, and a lower bladder neck.|
