Assessment of urinary incontinence in older adults, part 1

Author/s: 
Gibson, W., Molnar, F., Frank, C.

Clinical question
How should I assess my older patient who has urinary incontinence (UI)?

Bottom line
Urinary incontinence, the involuntary loss of any urine, is a common problem among people older than 65 or those living with frailty but should not be considered part of “normal” aging. The cornerstones of assessment are comprehensive history, basic physical examination, and focused investigations. Urinary incontinence is a multifactorial geriatric syndrome, not necessarily a disorder of the lower urinary tract itself. A detailed review of this topic was published in 2015 in the Canadian Geriatrics Society Journal of CME.

Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women

Author/s: 
Dumoulin, Chantale E., Hay-Smith, Jean C., Mac Habee-Seguin, Gabrielle

Background

Pelvic floor muscle training (PFMT) is the most commonly used physical therapy treatment for women with stress urinary incontinence (SUI). It is sometimes also recommended for mixed urinary incontinence (MUI) and, less commonly, urgency urinary incontinence (UUI).

This is an update of a Cochrane Review first published in 2001 and last updated in 2014.

Objectives

To assess the effects of PFMT for women with urinary incontinence (UI) in comparison to no treatment, placebo or sham treatments, or other inactive control treatments; and summarise the findings of relevant economic evaluations.

Search methods

We searched the Cochrane Incontinence Specialised Register (searched 12 February 2018), which contains trials identified from CENTRAL, MEDLINE, MEDLINE In‐Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP, handsearching of journals and conference proceedings, and the reference lists of relevant articles.

Selection criteria

Randomised or quasi‐randomised controlled trials in women with SUI, UUI or MUI (based on symptoms, signs or urodynamics). One arm of the trial included PFMT. Another arm was a no treatment, placebo, sham or other inactive control treatment arm.

Data collection and analysis

At least two review authors independently assessed trials for eligibility and risk of bias. We extracted and cross‐checked data. A third review author resolved disagreements. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions. We subgrouped trials by diagnosis of UI. We undertook formal meta‐analysis when appropriate.

Main results

The review included 31 trials (10 of which were new for this update) involving 1817 women from 14 countries. Overall, trials were of small‐to‐moderate size, with follow‐ups generally less than 12 months and many were at moderate risk of bias. There was considerable variation in the intervention's content and duration, study populations and outcome measures. There was only one study of women with MUI and only one study with UUI alone, with no data on cure, cure or improvement, or number of episodes of UI for these subgroups.

Symptomatic cure of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were eight times more likely to report cure (56% versus 6%; risk ratio (RR) 8.38, 95% confidence interval (CI) 3.68 to 19.07; 4 trials, 165 women; high‐quality evidence). For women with any type of UI, PFMT groups were five times more likely to report cure (35% versus 6%; RR 5.34, 95% CI 2.78 to 10.26; 3 trials, 290 women; moderate‐quality evidence).

Symptomatic cure or improvement of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were six times more likely to report cure or improvement (74% versus 11%; RR 6.33, 95% CI 3.88 to 10.33; 3 trials, 242 women; moderate‐quality evidence). For women with any type of UI, PFMT groups were two times more likely to report cure or improvement than women in the control groups (67% versus 29%; RR 2.39, 95% CI 1.64 to 3.47; 2 trials, 166 women; moderate‐quality evidence).

UI‐specific symptoms and quality of life (QoL) at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT group were more likely to report significant improvement in UI symptoms (7 trials, 376 women; moderate‐quality evidence), and to report significant improvement in UI QoL (6 trials, 348 women; low‐quality evidence). For any type of UI, women in the PFMT group were more likely to report significant improvement in UI symptoms (1 trial, 121 women; moderate‐quality evidence) and to report significant improvement in UI QoL (4 trials, 258 women; moderate‐quality evidence). Finally, for women with mixed UI treated with PFMT, there was one small trial (12 women) reporting better QoL.

Leakage episodes in 24 hours at the end of treatment: PFMT reduced leakage episodes by one in women with SUI (mean difference (MD) 1.23 lower, 95% CI 1.78 lower to 0.68 lower; 7 trials, 432 women; moderate‐quality evidence) and in women with all types of UI (MD 1.00 lower, 95% CI 1.37 lower to 0.64 lower; 4 trials, 349 women; moderate‐quality evidence).

Leakage on short clinic‐based pad tests at the end of treatment: women with SUI in the PFMT groups lost significantly less urine in short (up to one hour) pad tests. The comparison showed considerable heterogeneity but the findings still favoured PFMT when using a random‐effects model (MD 9.71 g lower, 95% CI 18.92 lower to 0.50 lower; 4 trials, 185 women; moderate‐quality evidence). For women with all types of UI, PFMT groups also reported less urine loss on short pad tests than controls (MD 3.72 g lower, 95% CI 5.46 lower to 1.98 lower; 2 trials, 146 women; moderate‐quality evidence).

Women in the PFMT group were also more satisfied with treatment and their sexual outcomes were better. Adverse events were rare and, in the two trials that did report any, they were minor. The findings of the review were largely supported by the 'Summary of findings' tables, but most of the evidence was downgraded to moderate on methodological grounds. The exception was 'participant‐perceived cure' in women with SUI, which was rated as high quality.

Authors' conclusions

Based on the data available, we can be confident that PFMT can cure or improve symptoms of SUI and all other types of UI. It may reduce the number of leakage episodes, the quantity of leakage on the short pad tests in the clinic and symptoms on UI‐specific symptom questionnaires. The authors of the one economic evaluation identified for the Brief Economic Commentary reported that the cost‐effectiveness of PFMT looks promising. The findings of the review suggest that PFMT could be included in first‐line conservative management programmes for women with UI. The long‐term effectiveness and cost‐effectiveness of PFMT needs to be further researched.

Nonsurgical Treatments for Urinary Incontinence in Women: A Systematic Review Update

Author/s: 
Balk, Ethan, Adam, Gaelen P., Kimmel, Hannah, Rofeberg, Valerie, Saeed, Iman, Jeppson, Peter, Trikalinos, Thomas

Introduction. About 17 percent of adult women have had urinary incontinence (UI), classified as stress, urgency, or mixed. Stress UI is associated with an inability to retain urine with activities that increase intraabdominal pressure. Urgency UI is associated with the sudden, compelling urge to void. Mixed UI occurs when both are present.

Methods. We updated the Agency for Healthcare Research and Quality's 2012 systematic review with new literature searches in MEDLINE®, the Cochrane Central Trials Registry, the Cochrane Database of Systematic Reviews, and Embase® from 2011 through December 4, 2017. We included UI outcomes (cure, improvement, satisfaction), quality of life, and adverse events. For UI outcomes, we conducted network meta-analyses, combining direct and indirect comparisons across studies. Quality of life and adverse event outcomes are narratively described.

Results. We identified 233 eligible studies, of which 140 reported on UI outcomes, 96 on quality of life, and 127 on adverse events. Studies evaluated 16 categories of interventions with 53 specific interventions. Fourteen intervention categories have been evaluated for UI outcomes; all except hormones and periurethral bulking agents were more effective to achieve at least one favorable UI outcome than no treatment (variable strength of evidence [SoE]). Among 1st or 2nd line interventions for stress UI, behavioral therapy (BT, alone and in combination with hormones) was more effective than either alpha agonists or hormones to achieve cure or improvement (moderate SoE); alpha agonists were more effective than hormones to achieve improvement (moderate SoE). Among treatments used as 1st or 2nd line interventions for urgency UI, BT was significantly more effective than anticholinergics to achieve cure or improvement (high SoE). Among 3rd line interventions for stress UI, intravesical pressure release, but not periurethral bulking agents, was more effective than no treatment (variable SoE). Neuromodulation, which is commonly used for treatment of urgency UI, is more effective than no treatment of stress UI for cure, improvement, and satisfaction (high SoE). Among studies of women with only stress UI, indirect evidence suggests that intravesical pressure release is more effective to achieve improvement than combination BT and neuromodulation, and triple combination neuromodulation, hormones, and BT may be more effective than either periurethral bulking or combination neuromodulation and BT (all low SoE). Among treatments used as 3rd line interventions for urgency UI, both neuromodulation and onabotulinum toxin A (BTX) are more effective than no treatment (high SoE), and BTX may be more effective than neuromodulation to achieve cure (low SoE). BT, neuromodulation, and anticholinergics resulted in better quality of life than no treatment (low SoE). Urinary tract infections (UTIs) were reported in 11 percent of women receiving transcutaneous electrical nerve stimulation and erosion in 1.6 percent of women with the periurethral bulking agent macroplastique (low SoE). Dry mouth was the most commonly reported adverse event for the anticholinergic oxybutynin (36%) and the alpha agonist duloxetine (13%) (high SoE). BTX was associated with UTIs (36%) and urinary retention (10% to 20%) (moderate SoE). Constitutional adverse events (e.g., nausea, insomnia, fatigue) were common with duloxetine (moderate SoE).

Conclusions. Network meta-analyses demonstrated that most nonpharmacological and pharmacological interventions are more likely than no treatment to improve UI outcomes and quality of life. BT, alone or in combination with other interventions, is generally more effective than 2nd line (pharmacological) therapies alone for both stress and urgency UI. Common adverse events with pharmacological treatments include dry mouth, nausea, and fatigue. BTX is associated with urinary infections and retention. Periurethral bulking agents are associated with erosion and need for surgical removal. Large gaps remain in the literature regarding head-to-head comparisons of individual interventions.
