The effect of midurethral slings on denovo urgency and urgency urinary incontinence.
Urinary incontinence (UI) is a relatively common condition in middle-aged and older women. Traditional measures of symptoms do not adequately capture the impact that UI has on individuals' lives. Further, severe morbidity and mortality are not associated with this condition. Rather, Ul's impact is primarily on the health status and health-related quality of life (HRQOL) of women. Generic measures of HRQOL inadequately address the impact of the condition on the day-to-day lives of women with UI. The current paper presents data on two new condition-specific instruments designed to assess the HRQOL of UI in women: the Urogenital Distress Inventory (UDI) and the Incontinence Impact Questionaire (IIQ). Used in conjunction with one another, these two measures provide detailed information on how UI affects the lives of women. The measures provide data on the more traditional view of HRQOL by assessing the impact of UI on various activities, roles and emotional states (IIQ), as well as data on the less traditional but critical issue of the degree to which symptoms associated with UI are troubling to women (UDI). Data on the reliability, validity and sensitivity to change of these measures demonstrate that they are psychometrically strong. Further, they have been developed for simple, self-administration.
To examine the impact of each type of urinary incontinence (stress, urge, and mixed) on health-related quality of life (HRQL).
The USA National Overactive Bladder Evaluation (NOBLE) programme of prevalence was used to identify respondents with incontinence based upon telephone survey responses. A nested case-control study was then conducted on respondents with symptoms of an overactive bladder (OAB), and on age and gender-matched controls; this consisted of the respondents completing a series of questionnaires, including the OAB-q (an HRQL scale for OAB), the Medical Outcomes Study (MOS) Short-Form-36 (SF-36), the MOS Sleep Scale, and the Center for Epidemiological Studies - Depression (CES-D) scale. Respondents were categorized into subgroups according to the primary cause of urine loss, i.e. sudden/uncomfortable urge to urinate (urge, UI), physical pressure (stress, SI), or both (mixed, MI). Descriptive analyses, t-tests and analysis of variance with post hoc comparisons were used.
Of the 919 participants in the nested case-control study, 171 reported incontinence, i.e. UI (69), SI (62) and MI (40). Among this cohort, 82.5% were female, 85.4% were Caucasian and the population had a mean age of 55.9 years. All OAB-q subscale scores were significantly (P < 0.01) worse among those with MI than with SI. Respondents with UI reported significantly higher levels of symptom bother and lower sleep scores (both P < 0.001) than those with SI. There were no differences in HRQL between the MI and UI groups. Voiding frequency and nocturia episodes did not differ among the groups but compared with the SI group, both UI and MI groups reported significantly higher ratings of urinary urge intensity (P < 0.001) and rated their need for medical care significantly higher (P < 0.01). The MI group reported more incontinence episodes (P = 0.02) than the SI group.
Compared with SI, respondents with UI and MI reported not only significantly greater ratings of urinary urge intensity and more incontinence episodes, but also significantly worse HRQL. These results are consistent with previous findings which indicated a greater impact on HRQL for the urge component of MI than for the stress component.
To systematically review the literature and to quantitatively compare outcomes and complications following retropubic vs transobturator approach to midurethral slings. We searched PUBMED, OVID, EMBASE, CINAHL, POPLINE, Web of Science, Cochrane Collaboration resources, TRIP, Global Health databases, and abstracts from relevant meetings from 1990 to 2006. We included all studies that compared retropubic and transobturator approaches to midurethral slings and that defined outcomes. We used random-effects models to estimate pooled odds ratios and 95% confidence intervals for objective and subjective failure, complications, and de novo irritative voiding symptoms. Six randomized trials and 11 cohort studies compared transobturator and retropubic approaches to midurethral slings. There was insufficient evidence to support if one approach leads to better objective outcomes. We found no difference in subjective failure between the 2 approaches after pooling data from randomized trials (pooled odds ratio OR 0.85, confidence interval 95% CI 0.38-1.92). The transobturator approach was associated with a decreased risk of complications (pooled OR 0.40, 95% CI 0.19-0.83]). The transobturator approach to midurethral slings is associated with a lower risk of complications; however, it is still unclear if one approach results in superior objective or subjective outcomes.
