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

Incontinence improves in older women after intensive pelvic floor muscle training: an assessor-blinded randomized controlled trial

AIMS

To test the hypotheses that high intensity pelvic floor muscle training (PFMT) is effective in relief of stress urinary incontinence in community dwelling older women, and that intense PFMT improves stress urinary incontinence more than bladder training (BT) in this population.

METHODS

A two-center, assessor-blinded randomized controlled trial of 20 weeks duration with two active intervention arms: PFMT and BT. Assessments and interventions were undertaken at two metropolitan tertiary hospitals. Participants were community dwelling women over 65 years of age with urodynamic stress incontinence. Primary outcome measure was urinary leakage during a cough stress test. Secondary outcome measures included symptoms and bother (ICIQ-UI SF), participant global perception of change, leakage episodes (7-day accident diary), degree of "bother" (VAS) and health related quality of life (AQoL).

RESULTS

Eighty-three Caucasian women, 71.8 (SD 5.3) years participated in the study. Both groups improved over the intervention period; however, the PFMT group reported significantly lower amounts of leakage on the stress test [PFMT median 0.0 g, 95% CI: 0.2-0.9; BT median 0.3 g, 95% CI: 0.2-1.7, P=0.006], improved symptoms and bother [PFMT mean 5.9, 95% CI: 4.8-7.1; BT group mean 8.5, 95% CI: 7.1-9.9 and greater perception of change [PFMT 28 (73.6%); BT 12 (36.4%) (P=0.002)] after 5 months than the BT group.

CONCLUSIONS

High intensity PFMT is effective in managing stress urinary incontinence and is more effective than BT in healthy older women.

Predicting improvement in urinary and bowel incontinence for home health patients using electronic health record data

PURPOSE

The purpose of the study was to discover which patient and support system characteristics and interventions documented by home health clinicians were associated with improvement in urinary and bowel incontinence contrasting logistic regression and data mining approaches.

SUBJECTS AND SETTING

Seventeen hundred ninety-three patients in this study experienced 2072 episodes of care. The study sample comprised all nonmaternity patients aged 18 years or older receiving skilled home health services in 2004. Subjects were drawn from a convenience sample of 15 home health agencies .

DESIGN

We completed a secondary analysis of data from 15 home health agencies' electronic health records. Data for this study were documented by home care clinicians using the Outcome and Assessment Information Set (OASIS) structured assessment form and the Omaha System interventions, which is a standardized terminology.

RESULTS

There were 684 patients with urinary incontinence and 187 with bowel incontinence. By discharge 38% improved in urinary incontinence and 45% improved their bowel incontinence. Using logistic regression, no patient or support system characteristics were identified that associated with improvement in either urinary or bowel incontinence, only a limited number of interventions were significant. A data mining decision tree was producible only for bowel incontinence, demonstrating a combination of patient and support system factors as well as selected interventions were important in determining whether patients would improve in bowel incontinence.

CONCLUSIONS

Home health patients have complex comorbid conditions requiring home care nurses to have broad, generalized knowledge. Future research is needed to determine if the inclusion of a certified WOC nurse would improve outcomes.

Adherence to behavioral interventions for urge incontinence when combined with drug therapy: adherence rates, barriers, and predictors

BACKGROUND

Behavioral intervention outcomes for urinary incontinence (UI) depend on active patient participation.

OBJECTIVE

The purpose of this study was to describe adherence to behavioral interventions (pelvic-floor muscle [PFM] exercises, UI prevention strategies, and delayed voiding), patient-perceived exercise barriers, and predictors of exercise adherence in women with urge-predominant UI.

DESIGN

This was a prospectively planned secondary data analysis from a 2-stage, multicenter, randomized clinical trial.

PATIENTS AND INTERVENTION

Three hundred seven women with urge-predominant UI were randomly assigned to receive either 10 weeks of drug therapy only or 10 weeks of drug therapy combined with a behavioral intervention for UI. One hundred fifty-four participants who received the combined intervention were included in this analysis.

MEASUREMENTS

Pelvic-floor muscle exercise adherence and exercise barriers were assessed during the intervention phase and 1 year afterward. Adherence to UI prevention strategies and delayed voiding were assessed during the intervention only.

RESULTS

During intervention, 81% of women exercised at least 5 to 6 days per week, and 87% performed at least 30 PFM contractions per day. Ninety-two percent of the women used the urge suppression strategy successfully. At the 12-month follow-up, only 32% of the women exercised at least 5 to 6 days per week, and 56% performed 15 or more PFM contractions on the days they exercised. The most persistent PFM exercise barriers were difficulty remembering to exercise and finding time to exercise. Similarly, difficulty finding time to exercise persisted as a predictor of PFM exercise adherence over time.

LIMITATIONS

Co-administration of medication for UI may have influenced adherence.

CONCLUSIONS

Most women adhered to exercise during supervised intervention; however, adherence declined over the long term. Interventions to help women remember to exercise and to integrate PFM exercises and UI prevention strategies into daily life may be useful to promote long-term adherence.

The overactive bladder

Urinary urgency and the associated symptoms which comprise overactive bladder are prevalent amongst the general population and adversely affect quality of life. Disease management consists of a sequential series of options starting with behavioural and lifestyle techniques, pharmacological management (antimuscarinics) and, in severe cases, surgical treatment (urinary diversion, neuromodulation, augmentation cystoplasty and detrusor myectomy). There is increasing recognition of pathophysiological mechanisms in the urothelium, interstitial cells and afferent neurons allowing the importance of peripheral integrative interaction to be identified. The hierarchy of the central nervous system control adds additional complexity to understanding the oflower urinary tract function. Some newer methods of treatment include Botulinum toxin A intramural injections, oral beta-3 adrenergic agonists and rho-kinase inhibitors. The lack of a disease generating hypothesis, the lack of animal models for disease and the subjective nature of the central symptom (urgency) still pose considerable theoretical and scientific hurdles that need to be overcome in the treatment of this condition.

Urinary incontinence in women: part 1 of a series of articles on incontinence

BACKGROUND

Urinary incontinence can arise in a woman of any age. Its prevalence is between 10% and 40%. The main clinical problems in urogynecology are stress urinary incontinence (involuntary leakage of urine on exertion, sneezing, or coughing) and the overactive bladder syndrome (nycturia, pollakisuria, and urinary urgency with or without incontinence).

METHOD

Selective literature search, with special attention to large-scale studies and to the guidelines of the German Society of Obstetrics and Gynecology (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, DGGG) and its Task Force on Urogynecology and Pelvic Floor Reconstruction (Arbeitsgemeinschaft Urogynäkologie und Beckenbodenrekonstruktion).

RESULTS

There are many diagnostic and therapeutic options, whose use should be based on the degree of the patient's suffering and on her motivation to be treated. Anticholinergic drugs are of established value in the treatment of overactive bladder. They are used in combination with possible lifestyle changes and bladder training. In some circum-stances, botulinum toxin injections can be considered as well. Stress incontinence should be treated conservatively (with pelvic floor training) before any surgical treatment is provided. The new tension-free vaginal tapes are just as effective as classic treatments, such as colposuspension, while being less invasive and enabling a more rapid recovery.

CONCLUSION

All women with urinary incontinence should undergo appropriate, specialized diagnostic evaluation and well-founded counseling in order to benefit from individualized treatment.

Medical management of overactive bladder

Overactive bladder (OAB), as defined by the International Continence Society, is characterized by a symptom complex including urinary urgency with or without urge incontinence, usually associated with frequency and nocturia. OAB syndrome has an incidence reported from six European countries ranging between 12-17%, while in the United States; a study conducted by the National Overactive Bladder Evaluation program found the incidence at 17%. In Asia, the prevalence of OAB is reported at 53.1%. In about 75%, OAB symptoms are due to idiopathic detrusor activity; neurological disease, bladder outflow obstruction (BOO) intrinsic bladder pathology and other chronic pelvic floor disorders are implicated in the others. OAB can be diagnosed easily and managed effectively with both non-pharmacological and pharmacological therapies. The first-line treatments are lifestyle interventions, bladder training, pelvic floor muscle exercises and anticholinergic drugs. Antimuscarinics are the drug class of choice for OAB symptoms; with proven efficacy, and adverse event profiles that differ somewhat.

Prevalence of major levator abnormalities in symptomatic patients with an underactive pelvic floor contraction

Introduction and hypothesis

Major levator ani abnormalities (LAA) may lead to abnormal pelvic floor muscle contraction (pfmC) and secondarily to stress urinary incontinence (SUI), prolapse, or fecal incontinence (FI).

Methods

A retrospective observational study included 352 symptomatic patients to determine prevalence of LAA in underactive pfmC and the relationship with symptoms. On 2D/3D transperineal ultrasound, PfmC was subjectively assessed as underactive (UpfmC) or normal (NpfmC) and quantified. LAA, defined as a complete avulsion of the pubic bone, was analyzed using tomographic ultrasound imaging.

Results

LAA were found in 53.8% of women with UpfmC versus 16.1% in NpfmC (P < 0.001). Patients with UpfmC were less likely to reduce hiatal area on pfmC (mean 7% reduction vs 25% in NpfmC (P < 0.001)). An UpfmC was associated with FI (P = 0.002), not with SUI or prolapse of the anterior and central compartment.

Conclusion

An underactive pfmC is associated with increased prevalence of LAA and FI.

A randomized clinical trial comparing pelvic floor muscle training to a Pilates exercise program for improving pelvic muscle strength

INTRODUCTION AND HYPOTHESIS

The purpose of this study is to determine whether a Pilates exercise program and a pelvic floor muscle-training (PFMT) program could provide similar improvements in pelvic muscle strength.

METHODS

Sixty-two women with little or no pelvic floor dysfunction were randomized to Pilates or PFMT. Each group had 24 biweekly 1-h sessions with either a physical therapist or Pilates instructor. Strength was measured via perineometry (cmH(2)O). Two questionnaires--pelvic floor distress inventory (PFDI-20) and pelvic floor impact questionnaire (PFIQ-7)--were also collected.

RESULTS

At baseline, the Pilates and PFMT groups measured 14.9 +/- 12.5 and 12.5 +/- 10.4 cmH(2)O, respectively (p = 0.41). Both the Pilates and PFMT groups got stronger (6.2 +/- 7.5 cmH(2)O, p = 0.0002 and 6.6 +/- 7.4 cmH(2)O, p = 0.0002, respectively), with no difference between groups p = 0.85. PFIQ and PFDI scores improved from baseline but not between groups.

CONCLUSIONS

Further study is required to determine if Pilates can actually treat pelvic floor dysfunction.

Vaginal weight cone versus assisted pelvic floor muscle training in the treatment of female urinary incontinence. A prospective, single-blind, randomized trial

INTRODUCTION AND HYPOTHESIS

Vaginal weight cone (VWC) versus assisted pelvic floor muscle training (APFMT) in the treatment of urinary incontinence (UI) in women.

METHODS

One hundred three incontinent women were randomly distributed into two groups: group G1 (n = 51) treated with VWC and G2 (n = 52), APFMT. The following parameters were performed initially and after treatment: (1) clinical questionnaire, (2) visual analogue scale (VAS), (3) 60-min pad test, and (4) subjective and objective assessment of pelvic floor muscle (PFM).

RESULTS

There was a significant decrease in nocturia and urine loss after treatment in both groups (p < 0.05). In VAS, there was a significant improvement of all parameters in both groups (p < 0.05). The pad test showed significant decrease in both groups (p < 0.05). There was a significant increase of PFM strength in both groups (p < 0.05).

CONCLUSION

There was no difference between groups treated with VWC and APFMT.

Evidence for benefit of transversus abdominis training alone or in combination with pelvic floor muscle training to treat female urinary incontinence: A systematic review

AIMS

Pelvic floor muscle training (PFMT) has Level A evidence to treat female urinary incontinence (UI). Recently, indirect training of the pelvic floor muscles (PFM) via the transversus abdominis muscle (TrA) has been suggested as a new method to treat UI. The aim of this article is to discuss whether there is evidence for a synergistic co-contraction between TrA and PFM in women with UI, whether TrA contraction is as effective, or more effective than PFMT in treating UI and whether there is evidence to recommend TrA training as an intervention strategy.

METHODS

A computerized search on PubMed, and hand searching in proceedings from the meetings of the World Confederation of Physical Therapy (1993-2007), International Continence Society and International Urogynecology Association (1990-2007) were performed.

RESULTS

While a co-contraction of the TrA normally occurs with PFM contraction, there is evidence that a co-contraction of the PFM with TrA contraction can be lost or altered in women with UI. No randomized controlled trials (RCTs) were found comparing TrA training with untreated controls or sham. Two RCTs have shown no additional effect of adding TrA training to PFMT in the treatment of UI.

CONCLUSIONS

To date there is insufficient evidence for the use of TrA training instead of or in addition to PFMT for women with UI. Neurourol. Urodyn. 28:368-373, 2009. (c) 2009 Wiley-Liss, Inc.

Group treatments for sensitive health care problems: a randomised controlled trial of group versus individual physiotherapy sessions for female urinary incontinence

Background

The aim was to compare effectiveness of group versus individual sessions of physiotherapy in terms of symptoms, quality of life, and costs, and to investigate the effect of patient preference on uptake and outcome of treatment.

Methods

A pragmatic, multi-centre randomised controlled trial in five British National Health Service physiotherapy departments. 174 women with stress and/or urge incontinence were randomised to receive treatment from a physiotherapist delivered in a group or individual setting over three weekly sessions. Outcome were measured as Symptom Severity Index; Incontinence-related Quality of Life questionnaire; National Health Service costs, and out of pocket expenses.

Results

The majority of women expressed no preference (55%) or preference for individual treatment (36%). Treatment attendance was good, with similar attendance with both service delivery models. Overall, there were no statistically significant differences in symptom severity or quality of life outcomes between the models. Over 85% of women reported a subjective benefit of treatment, with a slightly higher rating in the individual compared with the group setting. When all health care costs were considered, average cost per patient was lower for group sessions (Mean cost difference £52.91 95%, confidence interval (£25.82 - £80.00)).

Conclusion

Indications are that whilst some women may have an initial preference for individual treatment, there are no substantial differences in the symptom, quality of life outcomes or non-attendance. Because of the significant difference in mean cost, group treatment is recommended.

Clinical and instrumental parameters in patients with constipation and incontinence: their potential implications in the functional aspects of these disorders

PURPOSE

The aims of this study were to evaluate several clinical and instrumental parameters in a large number of patients with constipation and incontinence as well as in healthy controls and discuss their potential implications in the functional aspects of these disorders.

METHODS

Eighty-four constipated and 38 incontinent patients and 45 healthy controls were submitted to a protocol based on proctologic examination, clinico-physiatric assessment, and instrumental evaluation.

RESULTS

Constipated and incontinent patients had significantly worse lumbar lordosis as well as lower rate in the presence of perineal defense reflex than controls. Constipated but not incontinent patients had a lower rate of puborectalis relaxation than controls. Furthermore, worse pubococcygeal tests and a higher rate of muscle synergies presence, either agonist or antagonist, were observed in both constipated and incontinent patients compared to controls.

CONCLUSIONS

This study has demonstrated strong correlations between physiatric disorders and the symptoms of constipation and incontinence. Further studies designed to demonstrate a causal relationship between these parameters and the success of a specific treatment of the physiatric disorders on the proctology symptoms are warranted.

Challenges in designing a pragmatic clinical trial: the mixed incontinence -- medical or surgical approach (MIMOSA) trial experience

BACKGROUND

Mixed urinary incontinence (MUI) is a common, bothersome condition in women. In MUI, the two subtypes of urinary incontinence that coexist are treated differently; stress urinary incontinence (SUI) is primarily treated surgically while urge urinary incontinence (UUI) is primarily treated medically. There is no evidence to guide the treatment for women with significant bother from both incontinence subtypes. Therefore, investigators of the Urinary Incontinence Treatment Network (UITN) designed and initiated a randomized clinical trial comparing outcomes for two distinct initial treatment approaches for women with mixed urinary incontinence (MUI): therapy initiated with surgery versus therapy initiated with nonsurgical treatment.

PURPOSE

The aim of this manuscript is to describe the challenges in planning and implementing this randomized clinical trial.

METHODS

The mixed incontinence: medical or surgical approach (MIMOSA) trial was designed as a practical or pragmatic clinical trial to establish the relative efficacy of two specific treatment approaches. The design presented many challenging decisions including: (1) selection of practical paradigm; (2) refining inclusion/ exclusion criteria to offer equipoise; (3) selection of feasibility sample size; (4) recruitment challenges for two divergent treatment approaches (medical vs. surgical), and (5) resolution of ethical and methodological issues.

RESULTS

MIMOSA recruitment was planned in two phases, starting with a 5-month pilot and feasibility phase followed by a full trial contingent on the outcome of the first phase. The feasibility portion of the MIMOSA trial started in November 2008. 1198 subjects were screened and approached for study enrollment, but only 27 consented to randomization. The feasibility study was halted due to lack of enrollment in March 2009.

LIMITATIONS

The challenges of this trial included a lack of information from subjects who did not enroll, increasing the difficulty of interpreting the feasibility phase.

CONCLUSIONS

Successful recruitment to a randomized trial that compares significantly different treatment approaches poses a challenge.

The development of an Incontinence Treatment Motivation Questionnaire for patients undergoing pelvic floor physiotherapy in the treatment of stress incontinence

INTRODUCTION AND HYPOTHESIS

The aim of this paper is to develop a motivation questionnaire regarding perseverance in pelvic floor muscle training (PFMT) supervised by physiotherapists for stress urinary incontinence.

METHODS

Sixteen semi-structured interviews were conducted in women with stress urinary incontinence that revealed 15 common themes; 117 items were constructed and reviewed by continence advisors. Surviving items (n = 73) were administered to 210 women. Data were analysed for item properties, factor analysis was used to examine the questionnaire structure and tests of convergence/divergence used to check for sensitivity.

RESULTS

The Incontinence Treatment Motivation Questionnaire (ITMQ) comprises 18-items in five scales, assessing attitudes towards treatment (72.62% of explained variance; alpha = 0.87), reasons for not doing PFMT (55.73%; alpha = 0.74), living with incontinence (62.70% variance; alpha = 0.70), desire for treatment (65.37% variance; alpha = 0.74) and the effect of incontinence severity on PFMT (51.62% variance, alpha = 0.68). Scales were generally sensitive to known group differences.

CONCLUSIONS

This study represents the first effort to develop a motivation scale for PFMT. This validated Motivation Questionnaire is an instrument to test the impact of motivation upon cure, in PFMT.

Clarification and confirmation of the Knack maneuver: the effect of volitional pelvic floor muscle contraction to preempt expected stress incontinence

The aim of the study was to determine the immediate effect of timing a pelvic muscle contraction with the moment of expected leakage (the Knack maneuver) to preempt cough-related stress incontinence. Women performed a standing stress test using three hard coughs without and then with the Knack maneuver. Volume of urine loss under both conditions was quantified with paper-towel test. Two groups of women were tested: nonpregnant women (n = 64) and pregnant women (n = 29). In nonpregnant women, wetted area decreased from a median (range) of 43.2 (0.2-183.7) cm2 without the Knack maneuver to 6.9 (range of 0 to 183.7 cm2) with it (p < 0.0001); while in pregnant women it decreased from 14.8 (0-169.7) cm2 to 0 (0-96.5) cm2, respectively (p = 0.001). This study confirms the effect from the Knack maneuver as immediate and provides a partial explanation for early response to widely applied pelvic muscle training regimens in women with stress incontinence.

Urinary incontinence and pelvic organ prolapse: diagnosis and treatment for the primary care physician

This article outlines a simplified approach to diagnosis and treatment of women with urinary incontinence or pelvic organ prolapse that can be used by primary care physicians to identify patients with these conditions and initiate treatment for basic problems.

Menopause and the menopausal transition

Menopause and the menopausal transition present unique preventive health and quality-of-life challenges for women. The number of patients in the menopausal age group is increasing and represents a significant portion of the population. Care of the menopausal patient can be challenging for the caregiver. This chapter reviews the major health care challenges as well as evaluation and treatment of common quality-of-life issues for menopausal patients.

Electrical stimulation for faecal incontinence in adults

BACKGROUND

Faecal incontinence is a particularly embarrassing and distressing condition with significant medical, social and economic implications. Electrical stimulation has been used with apparent success in the treatment of faecal incontinence. However, standards of treatment are still lacking and the magnitude of alleged benefits has yet to be established.

OBJECTIVES

To determine the effects of electrical stimulation for the treatment of faecal incontinence in adults.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Trials Register (searched 13 March 2007) and reference lists of potentially eligible articles.

SELECTION CRITERIA

All randomised or quasi-randomised trials evaluating electrical stimulation in adults with faecal incontinence.

DATA COLLECTION AND ANALYSIS

Two reviewers assessed the methodological quality of potentially eligible trials and independently extracted data from the included trials. A wide range of outcome measures were considered.

MAIN RESULTS

Four eligible trials with 260 participants were identified. Findings from one trial suggest that electrical stimulation with anal biofeedback and exercises provides more short-term benefits than vaginal biofeedback and exercises for women with obstetric-related faecal incontinence. Another study found contradictory results, with no added benefit from electrical stimulation over biofeedback and exercises alone. Although all trials report that patient's symptoms are generally improved, it is not clear that this is the effect of electrical stimulation. No further conclusions could be drawn from the data available.

AUTHORS' CONCLUSIONS

At present, there are insufficient data to allow reliable conclusions to be drawn on the effects of electrical stimulation in the management of faecal incontinence. There is a suggestion that electrical stimulation may have a therapeutic effect, but this is not certain. Larger, more generalisable trials are needed.

Changes in levator ani anatomical configuration following physiotherapy in women with stress urinary incontinence

PURPOSE

We quantified the effect of pelvic floor muscle training on the anatomical configuration of the levator ani using magnetic resonance imaging.

MATERIALS AND METHODS

Five female participants with stress urinary incontinence underwent magnetic resonance imaging before and after participating in a pelvic floor muscle physiotherapy program. Axial T1-weighted images of the levator ani were taken with the participant in a supine position. Source images were then manually segmented and surface modeling was applied to build a 3-dimensional model of the levator ani. Models were then measured to determine the levator ani surface area as well as the encircled volume at rest and during voluntary contraction. The percentage of levator ani retraction and symphysis pubis movement during voluntary contraction before and after physiotherapy were also measured.

RESULTS

After physiotherapy the levator ani surface area at rest was significantly smaller than before physiotherapy, decreasing from 677.11 +/- 45.00 to 620.48 +/- 36.14 mm(2) (p = 0.04). The relative reduction in volume encircled by the levator ani during contraction increased significantly from -11.66 +/- 7.42 to -26.02 +/- 13.52 mm(3) (p = 0.04). Levator ani surface retraction during a voluntary contraction increased significantly from 65.61% +/- 17.07% to 81.70% +/- 16.30% (p = 0.02). Symphysis pubis movement during pelvic floor muscle contraction decreased from 1.45 +/- 1.32 to 0.44 +/- 0.61 mm (p = 0.05).

CONCLUSIONS

Findings from this preliminary study indicate that pelvic floor muscle training results in anatomical changes in the levator ani and reduction of pubic movement. These results provide insight into the possible anatomical mechanisms through which physiotherapy enables the pelvic floor muscle to minimize urine leakage.

Absorbent products for light urinary incontinence in women

BACKGROUND

Incontinence is a common and embarrassing problem which has a profound effect on social and psychological well-being. Many people wear absorbent products to contain urine leakage and protect their clothes. It can be difficult to define light urinary incontinence because urine volumes, flow and frequency rates may vary substantially whilst still being considered 'light'. Light incontinence may encompass occasional (monthly) leaks of very small amounts (e.g. 1 g to 2 g) up to frequent leaks (several times per day) of larger amounts (e.g. 20 g to 50 g). A practical definition is urine loss that can be contained within a small absorbent pad (typically 50 g to 500 g; ISO 1996).

OBJECTIVES

To assess the effectiveness of different types of absorbent product designs for women with light urinary incontinence.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Trials Register (3 May 2006) and the reference lists of relevant articles were perused.

SELECTION CRITERIA

TYPES OF STUDIES: All randomised or quasi-randomised trials of absorbent products for women with light urinary incontinence.

TYPES OF PARTICIPANTS

Women with light urinary incontinence. TYPES OF INTERVENTION: Absorbent products (disposable insert pads, menstrual pads, washable pants with integral pad, washable insert pads) suitable for light incontinence.

DATA COLLECTION AND ANALYSIS

Two review authors assessed the methodological quality of potentially eligible studies and independently extracted data from the included trial.

MAIN RESULTS

One study with 85 participants met the selection criteria. This trial studied all the absorbent product designs included in this review. Data were presented on all included outcomes. For preventing leakage, for preference and for overall acceptability disposable insert pads are better than disposable menstrual pads which are better than washable pants with integral pad which are better than washable insert pads. There is no strong evidence that either disposables or washables are better for skin health. The disposable insert is the most expensive design and there is no dominant design for cost-effectiveness. There is evidence that some women will prefer alternative designs which are all cheaper than disposable inserts.

AUTHORS' CONCLUSIONS

Although data were available from only one eligible trial the data were sufficiently robust to make recommendations for practice. Disposable insert pads are typically more effective than the other designs considered. However, because they are the most expensive, providing choice of designs (or combinations of designs for different circumstances) is likely to be cost-effective.

Conservative management of voiding dysfunction

This review article discusses the efficacy of various conservative therapies in the management of voiding dysfunction with special reference to urinary incontinence. The article emphasizes the fact that conservative therapies have limited side effects and they do not jeopardize future treatment options. Behaviour therapy, pelvic floor therapy and biofeedback; electrical and magnetic stimulation are discussed here individually. Though there is unanimous agreement that these therapies improve quality of life, complete cure is rare. All therapies work better in conjunction with each other rather than in isolation. The review also highlights the need for randomized controlled trials of better methodology.

Adherence to a behavioral program to prevent incontinence

This exploratory study assesses factors predicting adherence to a behavioral intervention to prevent urinary incontinence. Community-dwelling, post-menopausal women (N = 164) were taught pelvic floor muscle training (PFMT) and bladder training (BT) and followed with surveys for 1 year. Content analysis of open-ended responses coded descriptions of approaches participants used to incorporate PFMT into daily life. Exploratory bivariate and logistic regression analyses determined predictors of approach used and adherence. Results indicate women incorporated PFMT into their lives using either a routine or ad hoc approach. Those using a routine approach at 3 months were 12 times more likely to adhere (odds ratio [OR] = 12.4, confidence interval [CI] = 4.0-38.8, p < .001) at a high level at 3 months and significantly more likely to maintain that level 12 months post-intervention (OR = 2.7, CI = 1.2-6.0, p < .014). Practicing BT was related to high adherence.

Conservative management of pelvic organ prolapse in women

BACKGROUND

Pelvic organ prolapse is common, and some degree of prolapse is seen in 50% of parous women. Women with prolapse can experience a variety of pelvic floor symptoms. Treatments include surgery, mechanical devices and conservative management. Conservative management approaches, such as giving lifestyle advice and delivering pelvic floor muscle training, are often used in cases of mild to moderate prolapse.

OBJECTIVES

To determine the effects of conservative management (physical interventions and lifestyle interventions) for women with pelvic organ prolapse in comparison with no treatment or other treatment options (such as mechanical devices or surgery).

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Trials Register (searched on 19 September 2005), MEDLINE (January 1966 to August 2005), MEDLINE In Process & Other Citations (15 September 2005), EMBASE (January 1996 to Week 43 2005), CINAHL (January 1982 to October 2005), PEDro (September 2005), the UK National Research Register (Issue 3, 2005), the US National Institute of Health clinical trial register (5 October 2005), Current Controlled Trials register (5 October 2005), Controlled Clinical Trials (September 2005) and ZETOC (September 2005). We searched the reference lists of relevant articles.

SELECTION CRITERIA

Randomised and quasi-randomised trials in women with pelvic organ prolapse that included a physical or lifestyle intervention in at least one arm of the trial.

DATA COLLECTION AND ANALYSIS

Two reviewers assessed all trials for inclusion/exclusion and methodological quality. Data were extracted by the lead reviewer onto a standard form and cross checked by another. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

Three trials of relevance to this review were identified. The largest of these, of pelvic floor muscle training in preventing anterior prolapse from worsening, had significant limitations which affect the generalisability and rigor of the findings. A small feasibility study (which is to be followed up with a larger trial) randomised 47 women to pelvic floor muscle training or control and found suggestions of better outcomes (better self-reported improvement, decreased severity) in the intervention group. The third trial evaluated peri-operative physiotherapy for women undergoing surgery for prolapse and/or incontinence. The authors report that urinary symptoms, pelvic floor muscle function and quality of life were improved more in the treatment group than the control group, but data were not provided to allow this to be assessed. The trial was small and no prolapse-specific outcome measures were used. It was not possible to combine data from the three trials.

AUTHORS' CONCLUSIONS

Despite there now being reports of three eligible trials in this update, the evidence available is not significant to guide practice. There is some encouragement from a feasibility study that pelvic floor muscle training, delivered by a physiotherapist to symptomatic women in an outpatient setting, may reduce severity of prolapse. Further evidence from larger, better quality randomised control trials is however still necessary.

The impact of detrusor overactivity on the management of stress urinary incontinence in women

The presence of overactive bladder symptoms, urodynamic detrusor overactivity, and urge incontinence can complicate the diagnosis and management of stress urinary incontinence in women. The exact pathophysiology of mixed incontinence is not well characterized; in some patients, the stress and urge etiology may be pathologically linked. The role of urodynamics in evaluating patients with mixed incontinence remains controversial. Conservative therapies, such as bladder training, pelvic floor exercise, biofeedback, and electrical stimulation, offer moderate success in women with mixed incontinence. Surgery (colposuspension, bladder neck pubovaginal slings, and midurethral slings) offers excellent subjective and objective cure rates in patients with mixed incontinence. Preoperative detrusor overactivity is cured consistently 50%of the time with colposuspension and slings. Overall, the presence of preoperative detrusor overactivity does not appear to significantly worsen the outcome of conservative and surgical treatments for stress urinary incontinence in women.

Timed voiding for the management of urinary incontinence in adults

BACKGROUND

Timed voiding is a fixed time interval toileting assistance program that has been promoted for the management of people with urinary incontinence who cannot participate in independent toileting. For this reason, it is commonly assumed to represent current practice in residential aged care settings.

OBJECTIVES

To assess the effects of timed voiding for the management of urinary incontinence in adults who cannot participate in independent toileting.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group specialised register (9 May 2002), MEDLINE (January 1966 to December 2002), EMBASE (January 1980 to Week 18 2002), CINAHL (January 1982 to February 2001), PsycINFO (January 1972 to current), Biological Abstracts (January 1980 to December 2000), Current Contents (January 1993 to December 2001) and the reference lists of relevant articles. We also contacted experts in the field, searched relevant websites and handsearched journals and conference proceedings.

SELECTION CRITERIA

We selected all randomised and quasi-randomised trials that addressed timed voiding in an adult population and that had an alteration in continence status as a primary outcome. We included those trials that had assessed timed voiding delivered either alone or in combination with another intervention and compared it with either usual care, or no timed voiding, or another intervention.

DATA COLLECTION AND ANALYSIS

Data extraction and quality assessment were undertaken by at least two people working independently of each other. Any differences were resolved by discussion until agreement was reached. The relative risk for dichotomous data were calculated with 95% confidence intervals. Where data were insufficient to support a quantitative analysis, a narrative overview was undertaken.

MAIN RESULTS

Two trials with a total of 298 participants met the inclusion criteria. Both compared timed voiding plus additional intervention with usual care. In one of these timed voiding was combined with continence products, placement of a bedside commode for each participant, education to staff on transfer techniques, feedback and encouragement to staff, praise to participants for "successful responses" and administration of oxybutynin in small doses. The mean percentage who were incontinent when checked daily was 20% in the intervention group compared with 80% in the control group. No further between group analysis was possible from the data reported. The other trial combined timed voiding with a medical assessment and individualised medical management that was based on clinical data. Reduction in the number of participants with daytime and night-time incontinence was greater in the intervention group but this difference was statistically significant only for night-time wetting. There was no difference in the volume of urine lost as determined by pad weighing. The methodological quality of these trials was not high based on the quality appraisal criteria of the Cochrane Incontinence Group. In particular, there was a lack of clarity regarding levels of blinding. It was not possible to combine data from trials. In both trials, the fixed schedule of toileting was combined with other interventions. The extent to which the results reflect the contribution of timed voiding is unknown because the trials' design did not allow assessment of the effects of the fixed schedule of toileting separately from other components of the interventions.

REVIEWER'S CONCLUSIONS

The data were too few and of insufficient quality to provide empirical support for or against the intervention of timed voiding.

Habit retraining for the management of urinary incontinence in adults

BACKGROUND

Habit retraining is toileting assistance given by a caregiver to adults with urinary incontinence. It involves the identification of an incontinent person's natural voiding pattern and the development of an individualised toileting schedule which pre-empts involuntary bladder emptying.

OBJECTIVES

To assess the effects of habit retraining for the management of urinary incontinence in adults.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group specialised register (9 May 2002), MEDLINE (January 1966 to December 2002), EMBASE (January 1980 to Week 18 2002), CINAHL (January 1982 to February 2001), PsycINFO (January 1972 to current), Biological Abstracts (January 1980 to December 2000), Current Contents (January 1993 to December 2001) and the reference lists of relevant articles. We also contacted experts in the field, searched relevant websites and hand searched journals and conference proceedings.

SELECTION CRITERIA

All randomised or quasi-randomised controlled trials comparing habit retraining delivered either alone or in conjunction with another intervention for urinary incontinence in adults.

DATA COLLECTION AND ANALYSIS

Data extraction and quality assessment were undertaken by at least two people working independently of each other. Any differences were resolved by discussion. The relative risks for dichotomous data were calculated with 95% confidence intervals. Where data were insufficient for a quantitative analysis, a narrative overview was undertaken.

MAIN RESULTS

Three trials with a total of 337 participants met the inclusion criteria, describing habit retraining combined with other approaches compared with usual care. Participants were primarily care-dependent elderly women with concurrent cognitive and/or physical impairment, residing in either a residential aged-care facility or in their own home. Outcomes included incidence and/or severity of urinary incontinence, the prevalences of urinary tract infection, skin rash and skin breakdown, cost and caregiver preparedness, role strain and burden. Caregivers found it difficult to maintain voiding records and to implement the toileting program. A 61% compliance rate was reported in one trial. There were no statistically significant differences in the incidence and in the volume of incontinence between groups. Within group analyses did however show improvements on these measures. Reductions were also reported for the intervention group in one study for skin rash, skin breakdown and in caregivers' perceptions of their level of stress. Descriptive data on the intervention suggests that habit retraining is a labour-intense activity. Electronic loggers, used as an adjunct to caregiver-delivered wet/dry checks, were reported as providing more accurate data than that from caregiver conducted wet/dry checks. To date, no analysis of the time and resources associated with these comparisons is available.

REVIEWERS' CONCLUSIONS

Data on habit retraining are few and of insufficient quality to provide a firm basis for practice.

Anterior vaginal repair for urinary incontinence in women

BACKGROUND

Anterior vaginal repair (anterior colporrhaphy) is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience urinary incontinence.

OBJECTIVES

To determine the effects of anterior vaginal repair (anterior colporrhaphy) on stress or mixed urinary incontinence in comparison with other management options.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group's trials register, and the reference lists of relevant articles. Date of most recent search: September 2000.

SELECTION CRITERIA

Randomised or quasi-randomised trials that included anterior vaginal repair for the treatment of urinary incontinence.

DATA COLLECTION AND ANALYSIS

Both reviewers independently extracted data and assessed trial quality. Two trial investigators were contacted for additional information.

MAIN RESULTS

Nine trials were identified which included 333 women having an anterior vaginal repair and 599 who received comparison interventions. A single small trial provided insufficient evidence to assess anterior vaginal repair in comparison with physical therapy. The performance of anterior repair in comparison with needle suspension appeared similar but clinically important differences could not be confidently ruled out. No trials compared anterior repair with suburethral sling operations or laparoscopic retropubic suspensions, or compared alternative vaginal operations. Anterior vaginal repair was less effective than open abdominal retropubic suspension based on patient-reported cure rates in eight trials both in the short-term (failure rate within first year after anterior repair 82/279, 29% vs 50/346, 14%; RR 1.89, 95% CI 1.39 to 2.59) and long-term (after first year, 132/322, 41% vs 68/395, 17%; RR 2.50, 95% CI 1.92 to 3.26). There was evidence from three of these trials that this was reflected in more repeat operations for incontinence (25/107, 23% vs 4/164, 2%; RR 8.87, 95% CI 3.28 to 23.94). These findings held irrespective of the co-existence of prolapse (pelvic relaxation). Later prolapse operation appeared to be equally common after vaginal (3%) or abdominal (4%) operation. In respect of the type of open abdominal retropubic suspension, most data related to comparisons of anterior vaginal repair with Burch colposuspension. The few data describing comparison of anterior repair with the Marshall-Marchetti-Krantz procedure were consistent with those for Burch colposuspension.

REVIEWER'S CONCLUSIONS

There were not enough data to allow comparison of anterior vaginal repair with physical therapy or needle suspension for primary urinary stress incontinence in women. Open abdominal retropubic suspension appeared to be better than anterior vaginal repair judged on subjective cure rates in six trials, even in women who had prolapse in addition to stress incontinence (four trials). The need for repeat incontinence surgery was also less after the abdominal operation. However, there was not enough information about post-operative complications and morbidity.
