Epidemiology of Stress Urinary Incontinence in Women

Abstract

Stress urinary incontinence is common and affects many women globally. About 50% of women with urinary incontinence report symptoms of stress incontinence, but estimates of the prevalence and incidence are limited by inconsistent methods of measurement between epidemiologic studies in different populations. Estimates also are affected by underlying differences in the age and ethnicity of study populations. Longitudinal studies assessing the incidence and natural history of stress incontinence estimate an annual incidence of 4% to 10%. While remission does occur, data on this remains sparse. Multiple risk factors have been associated with stress incontinence and may to contribute to the development of the condition. Recent epidemiologic studies have focused on defining additional lower urinary tract symptoms besides mixed or urge incontinence that may be associated with stress incontinence, but the significance of this is not yet known.

Intrasphincteric autologous myoblast injections with electrical stimulation for stress urinary incontinence

“…Thirty-eight women participated in the trial (median age at baseline, 52 years; median parity, 2 [range, [1][2][3][4]; mean ± SD body mass index [calculated as weight in kilograms divided by the square of height in meters], 26.6 ± 4.4; and mean maximal urethral closure pressure, 57 ± 24 mm Hg). One participant did not present to the follow-up visit at 6 weeks because of other obligations but her available data were included in the analysis.…”

“…Stress urinary incontinence (SUI) is a highly prevalent condition in women [1]. The integrity of the urethral sphincter complex is necessary to maintain continence, especially that of the external rhabdosphincter, an omega-shaped muscle which compresses the urethra voluntarily [2].…”

Diagnostic delay in secondary care for lower urinary tract and pelvic organ prolapse symptoms in women

“…In one study of over 3 years' follow-up in women with diagnosed prolapse, the maximal vaginal descent increased by at least 2 cm in 11.0% of the women and decreased by at least 2 cm in 2.7%. Increasing body mass index and grand multiparity increased the risk for vaginal descent progression [14].…”

Evaluation and Management of Mid-Urethral Sling Complications

“…Female stress urinary incontinence (SUI) is estimated to affect half of all adult women, though this number varies widely in the literature [1]. The true prevalence may actually be much higher as many women are hesitant to discuss incontinence with their healthcare providers [2].…”
