The effects of drug and behavior therapy on urgency and voiding frequency

Non-Pharmacological Management of Urge Urinary Incontinence in Women between 40 and 65 Years Old: A Systematic Review

BACKGROUND

Urinary incontinence (UI) has been identified as a World Health Organization health priority. In particular, urge UI (UUI) refers to urine leakage associated with a sudden and compelling desire to void urine. It affects quality of life more than other kinds of UI, but it is not always treated adequately. For these reasons, this study aimed to evaluate the effectiveness of conservative treatment practices to counteract UUI in women aged 40-65 years old.

METHODS

This systematic review was conducted following the Joanna Briggs Institute (JBI) methodology. According to the protocol registered in PROSPERO, a systematic search was carried out in the CINAHL, Embase, PubMed, PsycInfo, Scopus and Web of Science databases up to October 2022, to find primary studies meeting the inclusion criteria.

RESULTS

Fourteen studies were included. The scientific literature reported different strategies dealing with the problem of UUI, some purely physical, others physical and psycho-educational and others exclusively psychological.

CONCLUSION

Conservative treatments are useful to aid the reduction in UUI episodes in middle-aged women. However, none of them can be considered more effective than others due to the impossibility of conducting meta-analytical analyses. Further studies comparing the effectiveness of conservative treatments for UUI are needed.

Bladder training for treating overactive bladder in adults

BACKGROUND

Overactive bladder (OAB) is a common chronic and bothersome condition. Bladder training is widely prescribed as a first-line treatment for OAB, but the efficacy has been systematically evaluated for urinary incontinence rather than OAB alone.

OBJECTIVES

To evaluate the benefits and harms of bladder training for treating adults with OAB compared to no treatment, anticholinergics, β3-adrenoceptor agonists, or pelvic floor muscle training (PFMT) alone or in combination.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was 6 November 2022.

SELECTION CRITERIA

We included randomized controlled trials involving adults aged 18 years or older with non-neurogenic OAB. We excluded studies of participants whose symptoms were caused by factors outside the urinary tract (e.g. neurologic disorders, cognitive impairment, gynecologic diseases).

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were 1. participant-reported cure or improvement, 2. symptom- and condition-related quality of life (QoL), and 3.

ADVERSE EVENTS

Secondary outcomes included 4. participant-reported satisfaction, 5. number of incontinence episodes, 6. number of urgency episodes, and 7. number of micturition episodes. For the purpose of this review, we considered two time points: immediately after the treatment (early phase) and at least two months after the treatment (late phase). We used GRADE to assess certainty of evidence for each outcome.

MAIN RESULTS

We included 15 trials with 2007 participants; participants in these trials were predominantly women (89.3%). We assessed the risk of bias of results for primary and secondary outcomes, which across all studies was similar and predominantly of high risk of bias, and none were at low risk of bias. The certainty of evidence was low to very low, with some moderate, across measured outcomes. Bladder training versus no treatment: three studies involving 92 participants compared bladder training to no treatment. The evidence is very uncertain about the effects of bladder training on cure or improvement at the early phase (risk ratio (RR) 17.00, 95% confidence interval (CI) 1.13 to 256.56; 1 study, 18 participants; very low-certainty evidence). Bladder training may reduce the number of incontinence episodes (mean difference (MD) -1.86, 95% CI -3.47 to -0.25; 1 study, 14 participants; low-certainty evidence). No studies measured symptom- and condition-related QoL, number of adverse events, participant-reported satisfaction, number of urgency episodes, or number of micturition episodes in the early phase. Bladder training versus anticholinergics: seven studies (602 participants) investigated the effects of bladder training versus anticholinergic therapy. Bladder training may be more effective than anticholinergics on cure or improvement at the early phase (RR 1.37, 95% CI 1.10 to 1.70; 4 studies, 258 participants; low-certainty evidence). The evidence is very uncertain about the effects of bladder training on symptom- and condition-related QoL (standardized mean difference (SMD) -0.06, 95% CI -0.89 to 0.77; 2 studies, 117 participants; very low-certainty evidence). Although the evidence is very uncertain, there were fewer adverse events in the bladder training group than in the anticholinergics group (RR 0.03, 95% CI 0.01 to 0.17; 3 studies, 187 participants; very low-certainty evidence). The evidence is very uncertain about the effects of the number of incontinence episodes per 24 hours (MD 0.36, 95% CI -0.27 to 1.00; 2 studies, 117 participants; very low-certainty evidence), the number of urgency episodes per 24 hours (MD 0.70, 95% CI -0.62 to 2.02; 2 studies, 92 participants; very low-certainty evidence), and the number of micturition episodes per 24 hours (MD -0.35, 95% CI -1.90 to 1.20; 3 studies, 175 participants; very low-certainty evidence). No studies measured participant-reported satisfaction in the early phase. Bladder training versus PFMT: three studies involving 203 participants compared bladder training to PFMT. The evidence is very uncertain about the different effects between bladder training and PFMT on symptom- and condition-related QoL at the early phase (SMD 0.10, 95% CI -0.19 to 0.40; 2 studies, 178 participants; very low-certainty evidence). There were no adverse events in either group at the early phase (1 study, 97 participants; moderate-certainty evidence). The evidence is uncertain about the effects of the number of incontinence episodes per 24 hours (MD 0.02, 95% CI -0.35 to 0.39, 1 study, 81 participants; low-certainty evidence) and very uncertain about the number of micturition episodes per 24 hours (MD 0.10, 95% CI -1.44 to 1.64; 1 study, 81 participants; very low-certainty evidence). No studies measured cure or improvement, participant-reported satisfaction, or number of urgency episodes in the early phase. Although we were interested in studies examining bladder training versus β3-adrenoceptor agonists, in combination with β3-adrenoceptor agonists versus β3-adrenoceptor agonists alone, and in combination with PFMT versus PFMT alone, we did not identify any eligible studies for these comparisons.

AUTHORS' CONCLUSIONS

This review focused on the effect of bladder training to treat OAB. However, most of the evidence was low or very-low certainty. Based on the low- or very low-certainty evidence, bladder training may cure or improve OAB compared to no treatment. Bladder training may be more effective to cure or improve OAB than anticholinergics, and there may be fewer adverse events. There may be no difference in efficacy or safety between bladder training and PFMT. More well-designed trials are needed to reach a firm conclusion.

Oral anticholinergic drugs versus placebo or no treatment for managing overactive bladder syndrome in adults

BACKGROUND

Around 16% of adults have symptoms of overactive bladder (OAB; urgency with frequency and/or urge incontinence), with prevalence increasing with age. Anticholinergic drugs are commonly used to treat this condition. This is an update of a Cochrane Review first published in 2002 and last updated in 2006.

OBJECTIVES

To assess the effects of anticholinergic drugs compared with placebo or no treatment for treating overactive bladder syndrome in adults.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 14 January 2020), and the reference lists of relevant articles. We updated this search on 3 May 2022, but these results have not yet been fully incorporated.

SELECTION CRITERIA

We included randomised or quasi-randomised trials in adults with overactive bladder syndrome that compared an anticholinergic drug alone with placebo treatment.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed eligibility and extracted data from the included studies, including an assessment of the risk of bias. We assessed the certainty of the body of evidence using the GRADE approach. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

We included 104 studies, 71 of which were new or updated for this version of the review. Although 12 studies did not report the number of participants, there were 47,106 people in the remainder of the included studies. The majority of the studies had insufficient information to allow judgement of risk of bias and we judged them to be unclear for all domains. Nine anticholinergic drugs were included in these studies: darifenacin; fesoterodine; imidafenacin; oxybutynin; propantheline; propiverine; solifenacin; tolterodine and trospium. No studies were found that compared anticholinergic drugs to no treatment. At the end of the treatment period, anticholinergics may slightly increase condition-specific quality of life (mean difference (MD) 4.41 lower, 95% confidence interval (CI) 5.28 lower to 3.54 lower (scale range -100 to 0); 12 studies, 6804 participants; low-certainty evidence). Anticholinergics are probably better than placebo in terms of patient perception of cure or improvement (risk ratio (RR) 1.38, 95% CI 1.15 to 1.66; 9 studies, 8457 participants; moderate-certainty evidence), and the mean number of urgency episodes per 24-hour period (MD 0.85 lower, 95% CI 1.03 lower to 0.67 lower; 23 studies, 16,875 participants; moderate-certainty evidence). Compared to placebo, anticholinergics may result in an increase in dry mouth adverse events (RR 3.50, 95% CI 3.26 to 3.75; 66 studies, 38,368 participants; low-certainty evidence), and may result in an increased risk of urinary retention (RR 3.52, 95% CI 2.04 to 6.08; 17 studies, 7862 participants; low-certainty evidence). Taking anticholinergics may be more likely to lead to participants withdrawing from the studies due to adverse events (RR 1.37, 95% CI 1.21 to 1.56; 61 studies, 36,943 participants; low-certainty evidence). However, taking anticholinergics probably reduces the mean number of micturitions per 24-hour period compared to placebo (MD 0.85 lower, 95% CI 0.98 lower to 0.73 lower; 30 studies, 19,395 participants; moderate-certainty evidence).

AUTHORS' CONCLUSIONS

The use of anticholinergic drugs by people with overactive bladder syndrome results in important but modest improvements in symptoms compared with placebo treatment. In addition, recent studies suggest that this is generally associated with only modest improvement in quality of life. Adverse effects were higher with all anticholinergics compared with placebo. Withdrawals due to adverse effects were also higher for all anticholinergics except tolterodine. It is not known whether any benefits of anticholinergics are sustained during long-term treatment or after treatment stops.

Combination and Novel Pharmacologic Agents for OAB

PURPOSE OF REVIEW

To evaluate recent literature on combination and novel pharmacologic therapies for overactive bladder (OAB).

RECENT FINDINGS

Combination therapies demonstrating greater efficacy than monotherapy include combination anticholinergics, anticholinergic plus β-3 agonist, and anticholinergic with behavioral modification, percutaneous tibial nerve stimulation, or sacral neuromodulation. Promising novel therapies include new bladder selective anticholinergics, new β-3 agonists, and gabapentin. OAB is a symptom complex caused by dysfunction in the interconnected neural, muscular, and urothelial systems that control micturition. Although several therapeutic targets and treatment options exist, complete resolution is not always achieved, discontinuation rate for medical therapy is high, and few patients subsequently progress to third-line treatment options. Recent literature suggests combination therapy diversifying therapeutic targets is more effective than targeting a single pathway and novel treatments targeting additional pathways have promising results.

Cognitive components of behavioral therapy for overactive bladder: a systematic review

INTRODUCTION AND HYPOTHESIS

Behavioral therapy is the first-line treatment for overactive bladder (OAB); however, the cognitive components of behavioral therapy for OAB have not been evaluated. The purposes of this systematic review were to describe the cognitive components of behavioral therapy for OAB and evaluate their effectiveness as well as to describe their rationale and origins.

METHODS

Searches were conducted on the PubMed, CINAHL, Web of Science, Cochrane and PEDro databases. Inclusion criteria were single-arm or randomized controlled trials on OAB treatment that utilized behavioral therapy, with a description of a cognitive component of the behavioral therapy. Study participants were neurologically intact adults (n = 1169). Study methodological quality was assessed with the PEDro and Newcastle-Ottawa scales.

RESULTS

Five studies were included, published between 2009 and 2020. Methodological quality was variable. All studies reported a reduction of symptoms in participants receiving behavioral therapy. Cognitive components of behavioral therapy were not extensively described. Distraction was the most common cognitive strategy for managing urgency. The relative impact of the cognitive aspect of behavioral therapy could not be evaluated, and the cognitive aspects of behavioral therapy appear to be accepted wisdom, traceable to several key authors, that has not been subjected to scientific investigation.

CONCLUSIONS

Behavioral therapy for OAB appears useful, but its cognitive components are not well described, their relative importance has not been evaluated or ascertained, nor have they been rigorously studied.

Overactive bladder - 18 years - Part I

Abstract: Overactive bladder syndrome is one of the lower urinary tract dysfunctions with the highest number of scientific publications over the past two decades. This shows the growing interest in better understanding this syndrome, which gathers symptoms of urinary urgency and increased daytime and nighttime voiding frequency, with or without urinary incontinence and results in a negative impact on the quality of life of approximately one out of six individuals – including both genders and almost all age groups. The possibility of establishing the diagnosis just from clinical data made patients' access to specialized care easier. Physiotherapy resources have been incorporated into the urological daily practice. A number of more selective antimuscarinic drugs with consequent lower adverse event rates were released. Recently, a new class of oral drugs, beta-adrenergic agonists has become part of the armamentarium for Overactive Bladder. Botulinum toxin injections in the bladder and sacral neuromodulation are routine modalities of treatment for refractory cases. During the 1st Latin-American Consultation on Overactive Bladder, a comprehensive review of the literature related to the evolution of the concept, epidemiology, diagnosis, and management was conducted. This text corresponds to the first part of the review Overactive Bladder 18-years.

Cholinergic Antagonists Combined with Electrical Stimulation or Bladder Training Treatments for Overactive Bladder in Female Adults: A Meta-Analysis of Randomized Controlled Trials

BACKGROUND AND OBJECTIVE

The therapeutic effects of cholinergic antagonists combined with non-drug therapy compared with cholinergic antagonist therapy alone for overactive bladder in adult women are unclear. Thus, we conducted a meta-analysis of randomized controlled trials to compare the therapeutic effects of cholinergic antagonists plus non-drug therapy (electrical stimulation and bladder training) with cholinergic antagonist therapy alone among female overactive bladder patients.

METHODS

Pertinent studies were identified by searching PubMed, Web of Science, and the Chinese Biological Medicine databases to May 31, 2016. Study-specific standardized mean differences were combined using fixed- or random-effects models depending on whether significant heterogeneity was detected.

RESULTS

Ten randomized controlled trials were identified. A total of 485 female overactive bladder patients were treated with the combined therapy and 497 were treated with the cholinergic antagonists alone. For the cholinergic antagonists combined with electrical stimulation treatment compared with cholinergic antagonist therapy alone, there were statistically significant reductions of average frequency of urination, incontinence, and urgency, with pooled standardized mean differences of -2.38, -1.32, and -0.87, respectively. There was also a statistically significant reduction of average frequency of urination (pooled standardized mean difference = - 0.30; 95 % confidence interval: -0.52 to -0.08) for the cholinergic antagonists combined with bladder training treatment compared with cholinergic antagonist therapy alone.

CONCLUSION

This study indicated that female overactive bladder patients with cholinergic antagonists combined with electrical stimulation or bladder training treatment may lower the average frequency of urination, incontinence, and urgency when compared with those who received isolated drug therapy.

Pelvic floor muscle training added to another active treatment versus the same active treatment alone for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training (PFMT) is a first-line conservative treatment for urinary incontinence in women. Other active treatments include: physical therapies (e.g. vaginal cones); behavioural therapies (e.g. bladder training); electrical or magnetic stimulation; mechanical devices (e.g. continence pessaries); drug therapies (e.g. anticholinergics (solifenacin, oxybutynin, etc.) and duloxetine); and surgical interventions including sling procedures and colposuspension. This systematic review evaluated the effects of adding PFMT to any other active treatment for urinary incontinence in women

OBJECTIVES

To compare the effects of pelvic floor muscle training combined with another active treatment versus the same active treatment alone in the management of women with urinary incontinence.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 5 May 2015), and CINAHL (January 1982 to 6 May 2015), and the reference lists of relevant articles.

SELECTION CRITERIA

We included randomised or quasi-randomised trials with two or more arms, of women with clinical or urodynamic evidence of stress urinary incontinence, urgency urinary incontinence or mixed urinary incontinence. One arm of the trial included PFMT added to another active treatment; the other arm included the same active treatment alone.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for eligibility and methodological quality and resolved any disagreement by discussion or consultation with a third party. We extracted and processed data in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. Other potential sources of bias we incorporated into the 'Risk of bias' tables were ethical approval, conflict of interest and funding source.

MAIN RESULTS

Thirteen trials met the inclusion criteria, comprising women with stress urinary incontinence (SUI), urgency urinary incontinence (UUI) or mixed urinary incontinence (MUI); they compared PFMT added to another active treatment (585 women) with the same active treatment alone (579 women). The pre-specified comparisons were reported by single trials, except bladder training, which was reported by two trials, and electrical stimulation, which was reported by three trials. However, only two of the three trials reporting electrical stimulation could be pooled, as one of the trials did not report any relevant data. We considered the included trials to be at unclear risk of bias for most of the domains, predominantly due to the lack of adequate information in a number of trials. This affected our rating of the quality of evidence. The majority of the trials did not report the primary outcomes specified in the review (cure or improvement, quality of life) or measured the outcomes in different ways. Effect estimates from small, single trials across a number of comparisons were indeterminate for key outcomes relating to symptoms, and we rated the quality of evidence, using the GRADE approach, as either low or very low. More women reported cure or improvement of incontinence in two trials comparing PFMT added to electrical stimulation to electrical stimulation alone, in women with SUI, but this was not statistically significant (9/26 (35%) versus 5/30 (17%); risk ratio (RR) 2.06, 95% confidence interval (CI) 0.79 to 5.38). We judged the quality of the evidence to be very low. There was moderate-quality evidence from a single trial investigating women with SUI, UUI or MUI that a higher proportion of women who received a combination of PFMT and heat and steam generating sheet reported a cure compared to those who received the sheet alone: 19/37 (51%) versus 8/37 (22%) with a RR of 2.38, 95% CI 1.19 to 4.73). More women reported cure or improvement of incontinence in another trial comparing PFMT added to vaginal cones to vaginal cones alone, but this was not statistically significant (14/15 (93%) versus 14/19 (75%); RR 1.27, 95% CI 0.94 to 1.71). We judged the quality of the evidence to be very low. Only one trial evaluating PFMT when added to drug therapy provided information about adverse events (RR 0.84, 95% CI 0.45 to 1.60; very low-quality evidence).With regard to condition-specific quality of life, there were no statistically significant differences between women (with SUI, UUI or MUI) who received PFMT added to bladder training and those who received bladder training alone at three months after treatment, on either the Incontinence Impact Questionnaire-Revised scale (mean difference (MD) -5.90, 95% CI -35.53 to 23.73) or on the Urogenital Distress Inventory scale (MD -18.90, 95% CI -37.92 to 0.12). A similar pattern of results was observed between women with SUI who received PFMT plus either a continence pessary or duloxetine and those who received the continence pessary or duloxetine alone. In all these comparisons, the quality of the evidence for the reported critical outcomes ranged from moderate to very low.

AUTHORS' CONCLUSIONS

This systematic review found insufficient evidence to state whether or not there were additional effects by adding PFMT to other active treatments when compared with the same active treatment alone for urinary incontinence (SUI, UUI or MUI) in women. These results should be interpreted with caution as most of the comparisons were investigated in small, single trials. None of the trials in this review were large enough to provide reliable evidence. Also, none of the included trials reported data on adverse events associated with the PFMT regimen, thereby making it very difficult to evaluate the safety of PFMT.

Clinical Guideline for Female Lower Urinary Tract Symptoms

The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery.

Eleven trials met the eligibility criteria for inclusion, comprising women with stress urinary incontinence (SUI), urgency urinary incontinence (UUI) or mixed urinary incontinence (MUI), and they compared PFMT added to another active treatment (494 women) with the same active treatment alone (490 women). The pre-specified comparisons were reported by single trials except electrical stimulation which was reported by two trials.

More women reported cure or improvement of incontinence in another trial comparing PFMT added to vaginal cones to vaginal cones alone: 14/15 (93%) versus 14/19 (75%), but this was not statistically significant (RR 1.27, 95% CI 0.94 to 1.71). We judged the quality of the evidence to be very low. Only one trial evaluating PFMT when added to drug therapy provided information about adverse events (RR 0.84, 95% CI 0.45 to 1.60; very low-quality evidence).With regard to condition-specific quality of life, there were no statistically significant differences between women (with SUI, UUI or MUI) who received PFMT added to bladder training and those who received bladder training alone at three months after treatment either on the Incontinence Impact Questionnaire-Revised scale (mean difference (MD) -5.90, 95% CI -35.53 to 23.73) or on the Urogenital Distress Inventory scale (MD -18.90, 95% CI -37.92 to 0.12).

These results should be interpreted with caution as most of the comparisons were investigated in small, single trials. None of the trials in this review were large enough to provide reliable evidence. Also, none of the included trials reported data on adverse events associated with the PFMT regimen, thereby making it very difficult to evaluate the safety of PFMT.

Anticholinergic drugs versus non-drug active therapies for non-neurogenic overactive bladder syndrome in adults

BACKGROUND

Overactive bladder syndrome is defined as urgency with or without urgency incontinence, usually with frequency and nocturia. Pharmacotherapy with anticholinergic drugs is often the first line medical therapy, either alone or as an adjunct to various non-pharmacological therapies after conservative options such as reducing intake of caffeine drinks have been tried. Non-pharmacologic therapies consist of bladder training, pelvic floor muscle training with or without biofeedback, behavioural modification, electrical stimulation and surgical interventions.

OBJECTIVES

To compare the effects of anticholinergic drugs with various non-pharmacologic therapies for non-neurogenic overactive bladder syndrome in adults.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register (searched 4 September 2012), which includes searches of the Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE, and the reference lists of relevant articles.

SELECTION CRITERIA

All randomised or quasi-randomised, controlled trials of treatment with anticholinergic drugs for overactive bladder syndrome or urgency urinary incontinence in adults in which at least one management arm involved a non-drug therapy. Trials amongst patients with neurogenic bladder dysfunction were excluded.

DATA COLLECTION AND ANALYSIS

Two authors evaluated the trials for appropriateness for inclusion and risk of bias. Two authors were involved in the data extraction. Data extraction was based on predetermined criteria. Data analysis was based on standard statistical approaches used in Cochrane reviews.

MAIN RESULTS

Twenty three trials were included with a total of 3685 participants, one was a cross-over trial and the other 22 were parallel group trials. The duration of follow up varied from two to 52 weeks. The trials were generally small and of poor methodological quality. During treatment, symptomatic improvement was more common amongst those participants on anticholinergic drugs compared with bladder training in seven small trials (73/174, 42% versus 98/172, 57% not improved: risk ratio 0.74, 95% confidence interval 0.61 to 0.91). Augmentation of bladder training with anticholinergics was also associated with more improvements than bladder training alone in three small trials (23/85, 27% versus 37/79, 47% not improved: risk ratio 0.57, 95% confidence interval 0.38 to 0.88). However, it was less clear whether an anticholinergic combined with bladder training was better than the anticholinergic alone, in three trials (for example 74/296, 25% versus 95/306, 31% not improved: risk ratio 0.80, 95% confidence interval 0.62 to 1.04). The other information on whether combining behavioural modification strategies with an anticholinergic was better than the anticholinergic alone was scanty and inconclusive. Similarly, it was unclear whether these complex strategies alone were better than anticholinergics alone.In this review, seven small trials comparing an anticholinergic to various types of electrical stimulation modalities such as Intravaginal Electrical Stimulation (IES), transcutaneous electrical nerve stimulation (TENS), the Stoller Afferent Nerve Stimulation System (SANS) neuromodulation and percutaneous posterior tibial nerve stimulation (PTNS) were identified. Subjective improvement rates tended to favour the electrical stimulation group in three small trials (54% not improved with the anticholinergic versus 28/86, 33% with electrical stimulation: risk ratio 0.64, 95% confidence interval 1.15 to 2.34). However, this was statistically significant only for one type of stimulation, percutaneous posterior tibial nerve stimulation (risk ratio 2.21, 95% confidence interval 1.13 to 4.33), and was not supported by significant differences in improvement, urinary frequency, urgency, nocturia, incontinence episodes or quality of life.The most commonly reported adverse effect among anticholinergics was dry mouth, although this did not necessarily result in withdrawal from treatment. For all comparisons there were too few data to compare symptoms or side effects after treatment had ended. However, it is unlikely that the effects of anticholinergics persist after stopping treatment. 

AUTHORS' CONCLUSIONS

The use of anticholinergic drugs in the management of overactive bladder syndrome is well established when compared to placebo treatment. During initial treatment of overactive bladder syndrome there was more symptomatic improvement when (a) anticholinergics were compared with bladder training alone, and (b) anticholinergics combined with bladder training were compared with bladder training alone. Limited evidence from small trials might suggest electrical stimulation is a better option in patients who are refractory to anticholinergic therapy, but more evidence comparing individual types of electrostimulation to the most effective types of anticholinergics is required to establish this. These results should be viewed with caution in view of the different classes and varying doses of individual anticholinergics used in this review. Anticholinergics had well recognised side effects, such as dry mouth.

Incontinence

Urinary incontinence is a common problem among older women and men. Older adults are reluctant to seek treatment, and health care providers should inquire about symptoms. Treatment of urinary incontinence includes multiple, office-based modalities, such as behavioral approaches, medications, and devices. Older adults may also consider surgical options to improve urinary incontinence. Special consideration should be given to older adults with cognitive impairment and incontinence.
