Outcome measures for research of lower urinary tract dysfunction in frail older people

Effect of different electrostimulation currents on female urinary incontinence: A protocol of a randomized controlled trial

INTRODUCTION

Urgency urinary incontinence (UUI) is characterized by involuntary urine leakage immediately after reporting of sudden, compelling desire to void. Electrostimulation and non-invasive neuromodulation have been considered as the first and third line of UUI treatment but there is a lack of consensus on which parameters are more efficient. Thus, this study aims to compare the effect of low versus medium frequency currents on urinary incontinence severity and quality of life in women with UUI complains.

METHODS

It will be a randomized controlled trial with 5 arms, double-blinded (outcome assessor and statistician). The study was approved by the Research Ethics Committee (CAAE: 11479119.9.0000.5406) and has been prospectively registered on the Brazilian Registry of Clinical Trials (RBR-8bkkp6). Concerning, double-blind process, the blinded assessor will be responsible for evaluate primary and secondary outcomes at baseline and follow-up without information about allocation and the statistician will perform analyses without information about group codification. One hundred and five participants will be randomized to receive: (1) Transcutaneous tibial nerve stimulation-low frequency, (2) Transcutaneous tibial nerve stimulation-high frequency, (3) Aussie median frequency, (4) Interferencial median frequency or (5) High voltage stimulation. The application will be performed during 20 sessions of 45-minutes, twice a week for 10 weeks, in groups of maximum 5 participants. The participants will be evaluated before treatment (baseline- 0 week), during the treatment (5 weeks) and after the last treatment session (10 weeks). The primary outcomes measures will be UI severity and quality of life, and the secondary outcome will be pelvic floor strength. Statistical analysis will be performed using SPSS software version 24.0 for Windows (IBM Corp., Armonk, N.Y., USA). The variables will be described by the mean and 95% confidence interval. The distribution of normality will be analyzed by the Shapiro-Wilk test. ANOVA for repeated measures will be performed. Mauchly's test the hypothesis of sphericity and when if this violated the hypotheses, the analyses will be based on the Greenhouse-Geisser test. Peer-to-peer comparisons will be performed using the Bonferroni Post-Hoc test. The significant level adopted will be 5% (p ≤ 0.05).

CONCLUSION

This study will enhance knowledge about effect of different neuromodulation currents in the improvement of UUI.

Does improved functional performance help to reduce urinary incontinence in institutionalized older women? A multicenter randomized clinical trial

Background

Urinary incontinence (UI) is a major problem in older women. Management is usually restricted to dealing with the consequences instead of treating underlying causes such as bladder dysfunction or reduced mobility.

The aim of this multicenter randomized controlled trial was to compare a group-based behavioral exercise program to prevent or reduce UI, with usual care. The exercise program aimed to improve functional performance of pelvic floor muscle (PFM), bladder and physical performance of women living in homes for the elderly.

Methods

Twenty participating Dutch homes were matched and randomized into intervention or control homes using a random number generator. Homes recruited 6–10 older women, with or without UI, with sufficient cognitive and physical function to participate in the program comprising behavioral aspects of continence and physical exercises to improve PFM, bladder and physical performance. The program consisted of a weekly group training session and homework exercises and ran for 6 months during which time the control group participants received care as usual. Primary outcome measures after 6 months were presence or absence of UI, frequency of episodes (measured by participants and caregivers (not blinded) using a 3-day bladder diary) and the Physical Performance Test (blinded). Linear and logistic regression analysis based on the Intention to Treat (ITT) principle using an imputed data set and per protocol analysis including all participants who completed the study and intervention (minimal attendance of 14 sessions).

Results

102 participants were allocated to the program and 90 to care as usual. ITT analysis (n = 85 intervention, n = 70 control) showed improvement of physical performance (intervention +8%; control −7%) and no differences on other primary and secondary outcome measures. Per protocol analysis (n = 51 intervention, n = 60 control) showed a reduction of participants with UI (intervention −40%; control −28%) and in frequency of episodes (intervention −51%; control −42%) in both groups; improvement of physical performance (intervention + 13%; control −4%) was related to participation in the exercise program.

Conclusions

This study shows that improving physical performance is feasible in institutionalized older women by exercise. Observed reductions in UI were not related to the intervention. [Current Controlled Trials ISRCTN63368283]

Surgery for pelvic organ prolapse: current status and future perspectives

PURPOSE OF REVIEW

The aim of this article is to highlight the latest developments and future perspectives of the surgical treatment of pelvic organ prolapse.

RECENT FINDINGS

The review of the relevant literature was performed through a complex search strategy including both free text and medical subject heading (MeSH) protocols. The search was limited to records written in English, concerning humans, and published in 2004. In addition, the Cochrane Database of Systematic Reviews was browsed for records regarding surgical treatment of pelvic organ prolapse. The selected papers were ranked according to the grade of evidence provided. Eight hundred and fifteen records were selected from a Medline search. We reviewed the abstracts of the records and selected 61 papers concerning the topic of the review. There was only one meta-analysis and four randomized clinical trials. All the other chosen studies were retrospective. The quality of the evidence found was poor. The evidence supported the use of mesh in anterior vaginal wall prolapse surgery and the indications both for abdominal sacrocolpopexy in case of vaginal vault prolapse and posterior colporrhaphy in case of rectocele. However, the data regarding lower urinary tract, bowel, sexual functions, generic quality of life issues, and long-term outcome were insufficient.

SUMMARY

Well designed, adequately powered, multicenter prospective randomized studies should be planned, including appropriate standardizations of methodology of pelvic organ prolapse staging (such as POP-Q system) and indications for treatment. Moreover, validated questionnaires should be used to assess the impact of surgery on functional and quality of life issues at adequate follow-up.

9 myths of incontinence in older adults: both clinicians and the over-65 set need to know more

Despite progress made in the research into and treatment of urinary incontinence, its incidence is rising among older adults. Many reasons for this disturbing finding have been posed: clinicians' insufficient knowledge of urinary incontinence, the reluctance of patients to discuss it, and inadequately individualized care. Common misconceptions of bladder health in older adults are explored to address these concerns and help prepare nurses in all settings to provide care that prevents and treats incontinence.

Clinical efficacy of tolterodine with or without a simplified pelvic floor exercise regimen

OBJECTIVES

To investigate whether the combination of tolterodine plus (Tp) a simple pelvic floor muscle exercise (PFME) program would provide improved treatment benefits compared with tolterodine alone (Ta) in patients with symptoms of overactive bladder (OAB).

METHODS

After a 1-2 week run-in period, 480 patients with symptoms of urinary frequency (> or =8 micturitions/24 hr), urgency, and urge incontinence (> or =1 episode/24 hr), were randomized to receive tolterodine 2 mg bid with or without a simple PFME program for 24 weeks in this multinational study. Treatment efficacy was assessed by comparing the change from baseline in 3-day micturition diary recordings.

RESULTS

After 24 weeks' treatment, in the Ta group the urgency episodes reduced from mean of 4.1 to 1.5 (83% reduction) while in the Tp group the urgency episodes reduced from 4.2 to 2.1 (78.7% reduction). Mean incontinence episodes per day decreased from 3.21 (standard deviation (SD) 3.4) to 0.95 (SD 1.9) in Ta group and from 3.44 (SD 3.4) to 1.25 (SD 2.7) in the Tp group. Similarly, the number of micturition/24 hr were significantly reduced, from 12.78 to 9.20 (27.3% reduction) in the Ta group and from 11.87 to 9.29 (23% reduction) in the Tp group. There was an improvement in the patients' perception of urinary symptoms in 85.9% of patients on Ta and 81.7% patients on Tp PFME. There were no statistically significant differences between the groups with regard to any of the outcome parameters.

CONCLUSIONS

Tolterodine therapy for 24 weeks results in significant improvement in urgency, frequency, and incontinence, however, no additional benefit was demonstrated for a simple PFME program.

Prompted voiding for the management of urinary incontinence in adults

BACKGROUND

Prompted voiding is a behavioural therapy used mainly in North American nursing homes. It aims to improve bladder control for people with or without dementia using verbal prompts and positive reinforcement.

OBJECTIVES

To assess the effects of prompted voiding for the management of urinary incontinence in adults.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group trials register (to February 2000) and reference lists of relevant articles. We contacted investigators in the field to locate extra studies. Date of the most recent searches: February 2000.

SELECTION CRITERIA

All randomised or quasi-randomised trials which addressed prompted voiding for the management of urinary incontinence. The trials included adult men and women, with or without cognitive impairment, diagnosed as having urinary incontinence as identified by the trialists, either by symptom classification or by urodynamic investigation.

DATA COLLECTION AND ANALYSIS

The identified reports were assessed for eligibility. Two reviewers independently reviewed the selected studies for methodological quality. Data describing six pre-specified outcomes were extracted independently by each reviewer and consensus reached when there was disagreement. Trial investigators were consulted when clarification or further detail was required. A third reviewer was recruited to proof read the review at different stages.

MAIN RESULTS

Five trials were included in the review. These involved 355 elderly people, most of whom were women. One other trial was excluded because no relevant outcome data were reported, and one trial is awaiting assessment. Prompted voiding was compared with no prompted voiding in four trials. The limited evidence suggested that prompted voiding increased self-initiated voiding and decreased incontinent episodes in the short-term. There was no evidence about long-term effects. A single small trial suggested that adding the muscle relaxant, Oxybutinin, reduced the number of incontinent episodes in the short-term: This study used a cross-over design and so did not address long-term effects.

REVIEWER'S CONCLUSIONS

There was insufficient evidence to reach firm conclusions for practice. There was suggestive, although inconclusive, evidence of short-term benefit from prompted voiding and from adding the muscle relaxant, Oxybutinin to prompted voiding.
