Transvaginal electrical stimulation in the treatment of urinary incontinence

Comparison of the efficacy of intravaginal electrical stimulation in women with idiopathic overactive bladder naive and refractory to pharmacological agents

INTRODUCTION AND HYPOTHESIS

This study aims to compare the effectiveness of intravaginal electrical stimulation (IVES) with regard to quality of life (QoL) and clinical parameters related to incontinence in women with idiopathic overactive bladder (iOAB) naive or refractory to treatment with pharmacological agents (PhA).

METHODS

In this prospective trial, PhA-naive women were included in Group 1 (n = 24) and women with PhA-resistant iOAB were included in Group 2 (n = 24). IVES was performed 3 days a week, with a total of 24 sessions for 8 weeks. Every session lasted 20 minutes. Women were evaluated for the severity of incontinence (24-hour pad test), pelvic floor muscle (PFM) strength (perineometer), 3-day voiding diary (frequency of voiding, nocturia, incontinence episodes, and the number of pads), symptom severity (OAB-V8), quality of life (IIQ-7), treatment success (positive response rate), cure/improvement rate, and treatment satisfaction.

RESULTS

A statistically significant improvement was found in all parameters for each group at the 8th week compared to the baseline values (p < 0.05). At the 8th week, there were no statistically significant differences in the severity of incontinence, PFM strength, incontinence episodes, nocturia, number of pads, QoL, treatment satisfaction, cure-improvement, or positive response rates between the two groups (p > 0.05). It was found that the frequency of voiding and symptom severity parameters were significantly more improved in Group 1 than in Group 2 (p < 0.05).

CONCLUSIONS

Although IVES was more effective in PhA-naive women with iOAB, it also appears to be an effective treatment in the management of women with PhA-resistant iOAB.

Conservative interventions for treating urinary incontinence in women: an Overview of Cochrane systematic reviews

BACKGROUND

Urinary incontinence (UI) is the involuntary loss of urine and can be caused by several different conditions. The common types of UI are stress (SUI), urgency (UUI) and mixed (MUI). A wide range of interventions can be delivered to reduce the symptoms of UI in women. Conservative interventions are generally recommended as the first line of treatment.

OBJECTIVES

To summarise Cochrane Reviews that assessed the effects of conservative interventions for treating UI in women.

METHODS

We searched the Cochrane Library to January 2021 (CDSR; 2021, Issue 1) and included any Cochrane Review that included studies with women aged 18 years or older with a clinical diagnosis of SUI, UUI or MUI, and investigating a conservative intervention aimed at improving or curing UI. We included reviews that compared a conservative intervention with 'control' (which included placebo, no treatment or usual care), another conservative intervention or another active, but non-conservative, intervention. A stakeholder group informed the selection and synthesis of evidence. Two overview authors independently applied the inclusion criteria, extracted data and judged review quality, resolving disagreements through discussion. Primary outcomes of interest were patient-reported cure or improvement and condition-specific quality of life. We judged the risk of bias in included reviews using the ROBIS tool. We judged the certainty of evidence within the reviews based on the GRADE approach. Evidence relating to SUI, UUI or all types of UI combined (AUI) were synthesised separately. The AUI group included evidence relating to participants with MUI, as well as from studies that combined women with different diagnoses (i.e. SUI, UUI and MUI) and studies in which the type of UI was unclear.

MAIN RESULTS

We included 29 relevant Cochrane Reviews. Seven focused on physical therapies; five on education, behavioural and lifestyle advice; one on mechanical devices; one on acupuncture and one on yoga. Fourteen focused on non-conservative interventions but had a comparison with a conservative intervention. No reviews synthesised evidence relating to psychological therapies. There were 112 unique trials (including 8975 women) that had primary outcome data included in at least one analysis. Stress urinary incontinence (14 reviews) Conservative intervention versus control: there was moderate or high certainty evidence that pelvic floor muscle training (PFMT), PFMT plus biofeedback and cones were more beneficial than control for curing or improving UI. PFMT and intravaginal devices improved quality of life compared to control. One conservative intervention versus another conservative intervention: for cure and improvement of UI, there was moderate or high certainty evidence that: continence pessary plus PFMT was more beneficial than continence pessary alone; PFMT plus educational intervention was more beneficial than cones; more-intensive PFMT was more beneficial than less-intensive PFMT; and PFMT plus an adherence strategy was more beneficial than PFMT alone. There was no moderate or high certainty evidence for quality of life. Urgency urinary incontinence (five reviews) Conservative intervention versus control: there was moderate to high-certainty evidence demonstrating that PFMT plus feedback, PFMT plus biofeedback, electrical stimulation and bladder training were more beneficial than control for curing or improving UI. Women using electrical stimulation plus PFMT had higher quality of life than women in the control group. One conservative intervention versus another conservative intervention: for cure or improvement, there was moderate certainty evidence that electrical stimulation was more effective than laseropuncture. There was high or moderate certainty evidence that PFMT resulted in higher quality of life than electrical stimulation and electrical stimulation plus PFMT resulted in better cure or improvement and higher quality of life than PFMT alone. All types of urinary incontinence (13 reviews) Conservative intervention versus control: there was moderate to high certainty evidence of better cure or improvement with PFMT, electrical stimulation, weight loss and cones compared to control. There was moderate certainty evidence of improved quality of life with PFMT compared to control. One conservative intervention versus another conservative intervention: there was moderate or high certainty evidence of better cure or improvement for PFMT with bladder training than bladder training alone. Likewise, PFMT with more individual health professional supervision was more effective than less contact/supervision and more-intensive PFMT was more beneficial than less-intensive PFMT. There was moderate certainty evidence that PFMT plus bladder training resulted in higher quality of life than bladder training alone.

AUTHORS' CONCLUSIONS

There is high certainty that PFMT is more beneficial than control for all types of UI for outcomes of cure or improvement and quality of life. We are moderately certain that, if PFMT is more intense, more frequent, with individual supervision, with/without combined with behavioural interventions with/without an adherence strategy, effectiveness is improved. We are highly certain that, for cure or improvement, cones are more beneficial than control (but not PFMT) for women with SUI, electrical stimulation is beneficial for women with UUI, and weight loss results in more cure and improvement than control for women with AUI. Most evidence within the included Cochrane Reviews is of low certainty. It is important that future new and updated Cochrane Reviews develop questions that are more clinically useful, avoid multiple overlapping reviews and consult women with UI to further identify outcomes of importance.

Efficacy of intravaginal electrical stimulation with different treatment frequency in women with refractory idiopathic overactive bladder

Objective

The aim of this study is to evaluate the effect of intravaginal electrical stimulation (IVES) therapies with different treatment frequencies (two or five days in a week) added to bladder training (BT) on incontinence-related quality of life (QoL) and clinical parameters in women with refractory idiopathic overactive bladder (OAB).

Material and Methods

Fifty-two women with refractory idiopathic OAB were randomized into two groups as follows: Group 1 (n:26) received BT and IVES, two times in a week, for 10 weeks and Group 2 (n:26) received BT and IVES five times in a week, for 4 weeks. IVES was performed 20 minutes in a day, a total of 20 sessions for both groups. Women were evaluated for incontinence severity (24h pad test), pelvic floor muscles strength (perineometer), 3-day voiding diary (frequency of voiding, nocturia, incontinence episodes, and the number of pads), symptom severity (OAB-V8), quality of life (IIQ-7), treatment success (positive response rate), cure/improvement rate and treatment satisfaction (Likert scale).

Results

There was no statistically significant differences in all parameters between the two groups at the end of the treatment. It was found that the treatment satisfaction scores, cure/improvement and positive response rates were not significantly different between two groups (p>0.05).

Conclusion

We concluded that the application of IVES twice a week or 5 times a week added to BT were both effective on incontinence-related QoL and clinical parameters in women with refractory idiopathic OAB. These two IVES frequencies had similar clinical efficacy and patient satisfaction with a slight difference between them; 5 times per week IVES has a shorter treatment duration.

Pelvic floor rehabilitation in the treatment of mixed urinary incontinence among women

Background

Mixed urinary incontinence (MUI) is a common underreported problem among females; it has a major effect on patients’ quality of life. Treatment may be difficult since a single modality cannot be enough to alleviate both the urge and the stress symptoms. Biofeedback-assisted pelvic floor muscle training (PFMT) has a great role in strengthening the pelvic floor muscles especially when accompanied by electrical stimulation. Neuromodulation is another safe well-tolerated method that may improve symptoms of female voiding dysfunction. There are no previous studies that assessed the efficacy of biofeedback-assisted pelvic floor muscle training versus two different types of peripheral neuromodulation which are transcutaneous posterior tibial nerve stimulation (TPTNS) and anogenital neuromodulation in the treatment of mixed urinary incontinence among women. The aim of this work is to study the effectiveness of biofeedback-assisted pelvic floor muscle training with electrostimulation versus two different methods of peripheral neuromodulation techniques in the treatment of women with MUI. Patients were subjected to history taking, assessment questionnaires (Questionnaire for female Urinary Incontinence Diagnosis (QUID), Australian Pelvic Floor Questionnaire (PFQ), and International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF)), clinical examination, and manometric pressure assessment. The patients were allocated randomly into three groups. Group I received biofeedback-assisted pelvic floor muscle training and faradic electrical stimulation, group II received posterior tibial neuromodulation, and group III received anogenital neuromodulation.

Results

The present study included 68 non-virgin female patients with mixed urinary incontinence. Significant improvement was noticed in the three studied groups on the subjective and objective levels. No statistically significant difference was reported between the studied groups following the different types of intervention.

Conclusions

Biofeedback-assisted pelvic floor muscle training with electrostimulation is as effective as anogenital neuromodulation and posterior tibial neuromodulation in the treatment of mixed urinary incontinence among females.

Evaluating the primary use, strengths and weaknesses of pelvic floor muscle training devices available online

AIMS

Treatment for urinary incontinence (UI) includes pelvic floor muscle training (PFMT). There is limited data appraising the characteristics of PFMT devices. We aimed to ascertain the primary use, strengths and weaknesses of PFMT devices available online, through evaluation of consumer reviews.

METHODS

We performed an analysis of PFMT devices on Amazon.com. Four key device categories were recognized. Reviews from the five most frequently-reviewed products per category were analyzed (n = 20). W characterized device use, strengths and weaknesses using thematic analysis.

RESULTS

We evaluated 2574 PFMT device reviews including 1168 vibrating Kegel balls, 750 non-vibrating Kegel balls, 411 pelvic floor or thigh exercisers, and 245 electric probes. Non-vibrating Kegel balls were rated highest (4.6/5 stars), followed by vibrating Kegel balls, electric probes and pelvic floor or thigh exercisers (4.4/5, 4.1/5, and 3.8/5 stars, respectively). Most reviews were positive (77%) or negative (16%) with few neutral (7%). While all were marketed to treat UI, most reviews did not mention the intended use. Vibrating and non-vibrating Kegel balls and electric probes were most likely to be used for UI, and pelvic floor or thigh exercisers for toning. Some used non-vibrating and vibrating Kegel balls for sexual function. Electric probes were the most beneficial device for incontinence control (27%, 67/245). Twenty-five percent of all product reviews praised device ease of use and good quality or design. A minority of reviewers found products difficult to use, of poor quality or design and uncomfortable.

CONCLUSION

Consumers utilized online PFMT devices for multiple purposes, including UI, toning and sexual function. Reviewers generally praised PFMT products, particularly electric probes for UI.

Urinary Incontinence in Women: Modern Methods of Physiotherapy as a Support for Surgical Treatment or Independent Therapy

Urinary incontinence (UI) is a common health problem affecting quality of life of nearly 420 million people, both women and men. Pelvic floor muscle (PFM) training and other physiotherapy techniques play an important role in non-surgical UI treatment, but their therapeutic effectiveness is limited to slight or moderate severity of UI. Higher UI severity requires surgical procedures with pre- and post-operative physiotherapy. Given that nearly 30%–40% of women without dysfunction and about 70% with pelvic floor dysfunction are unable to perform a correct PFM contraction, therefore, it is particularly important to implement physiotherapeutic techniques aimed at early activation of PFM. Presently, UI physiotherapy focuses primarily on PFM therapy and its proper cooperation with synergistic muscles, the respiratory diaphragm, and correction of improper everyday habits for better pelvic organ support and continence. The purpose of this work is a systematic review showing the possibilities of using physiotherapeutic techniques in the treatment of UI in women with attention to the techniques of PFM activation. Evidence of the effectiveness of well-known (e.g., PFM training, biofeedback, and electrostimulation) and less-known (e.g., magnetostimulation, vibration training) techniques will be presented here regarding the treatment of symptoms of urinary incontinence in women.

Effects of low-frequency intravaginal electrical stimulation on female urinary incontinence, quality of life, and urinary symptoms: A pilot study

This study investigated the effects of a low-frequency home-based incontinence therapy device on quality of life (QoL) and urinary symptoms in women with urinary incontinence. From May 2017 to February 2018, 34 patients, aged ≥ 20 years, with involuntary urine leakage >2 times/week, were recruited to this study. Patients with severe pelvic organ prolapse, pregnancy, virgin status, and psychological problems were excluded. The incontinence home-care device treatments were administered in 12-minute sessions, twice daily for 8 weeks. Simultaneously, hyperthermic conditions of 35°C to 40°C and microvibrations were administered. All patients completed urinary incontinence questionnaires (King's Health Questionnaire [KHQ], Bristol Female Lower Urinary Tract Symptoms [BFLUTS] questionnaire, and the Overactive Bladder Symptom Score [OABSS]) before treatment, as well as 4 and 8 weeks into treatment. Changes in the questionnaire responses over time were compared. Two participants dropped out of the study and there was one screening failure, leaving 31 patients for analysis. After 4 weeks treatment, there were significant improvements in symptoms, such as role limitation, physical limitation, social limitation, personal relationship, emotion, sleep/energy, and severity measures. After 8 weeks treatment, almost all parameters on the KHQ revealed symptomatic improvement. On the BFLUTS, voiding times during activity, nocturia, urgency, urge incontinence, incontinence frequency, stress incontinence, volume leakage, strain to start, intermittency, reduced stream, acute retention, incomplete emptying, and stopping flow showed significant improvements. On the OABSS, almost all storage symptoms improved. Low-frequency electrical stimulation devices were effective at improving urinary incontinence, which became evident as the duration of treatment increased. Improvement of urgency and frequency was more evident after treatment.

Safety and Efficacy of a Non-Invasive High-Intensity Focused Electromagnetic Field (HIFEM) Device for Treatment of Urinary Incontinence and Enhancement of Quality of Life

Background and Objectives

Urinary incontinence is a common and distressing condition which interferes with everyday life. Patients frequently experience discomfort related to urine leakage and the subsequent need to use absorbent pads. Since the continence mechanism is primarily maintained by a proper function of pelvic floor muscles (PFM), many treatment methods focused on strengthening of the PFM have been introduced in the past. The aim of this study was to evaluate the safety and efficacy of a high‐intensity focused electromagnetic technology (HIFEM) for treatment of urinary incontinence with emphasis on effects on prospective patients’ quality of life.

Study Design/Materials and Methods

The study followed an institutional review board approved protocol. A total of 75 women (55.45 ± 12.80 years, 1.85 ± 1.28 deliveries) who showed symptoms of stress, urge, or mixed urinary incontinence were enrolled. They received six HIFEM treatments (2 per week) in duration of 28 minutes. Outcomes were evaluated after the sixth treatment and at the 3‐month follow‐up. The primary outcome was to assess changes in urinary incontinence by the International Consultation on Incontinence Questionnaire‐Short Form (ICIQ‐SF) and changes in the number of absorbent pads used per day. The secondary outcome was subjective evaluation of the therapy and self‐reported changes in quality of life. The statistical analysis was conducted by paired T‐test and Pearson correlation coefficient ( α = 0.05).

Results

After the sixth session, 61 out of 75 patients (81.33%) reported significant reduction of their symptoms. The average improvement of 49.93% in ICIQ‐SF score was observed after the sixth treatment, which further increased to 64.42% at the follow‐up (both P < 0.001). Individually, the highest level of improvement was reached in patients suffering from mixed urinary incontinence (69.90%). The reduction of absorbent pads averaged 43.80% after the sixth treatment and 53.68% at 3 months (both P < 0.001), while almost 70% of patients (30 out of 43) reported decreased number of used pads. At the follow‐up, a highly significant medium correlation (r = 0.53, P < 0.001) was found between the ICIQ‐SF score improvement and the reduction in pad usage. A substantial decrease in the frequency of urine leakage triggers was documented. Patients reported no pain, downtime or adverse events, and also reported additional beneficial effects of the therapy such as increased sexual desire and better urination control.

Conclusions

This study demonstrated that HIFEM technology is able to safely and effectively treat a wide range of patients suffering from urinary incontinence. After six treatments, an improvement in ICIQ‐SF score and reduction in absorbent pads usage was observed. Based on subjective evaluation, these changes positively influenced quality of life. © 2019 The Authors. Lasers in Surgery and Medicine Published by Wiley Periodicals, Inc.

Prospective Outcomes of a Pelvic Floor Rehabilitation Program Including Vaginal Electrogalvanic Stimulation for Urinary, Defecatory, and Pelvic Pain Symptoms

OBJECTIVES

This study evaluated our experience after implementing a pelvic floor rehabilitation program including behavioral modification, biofeedback, and vaginal electrogalvanic stimulation (EGS).

METHODS

This prospective cohort study evaluated outcomes of patients with pelvic floor dysfunction (urinary or defecatory dysfunction, pelvic pain/dyspareunia) who underwent pelvic floor rehabilitation. Patients received 4 to 7 sessions (1 every 2 weeks) including biofeedback and concluded with 30 minutes of vaginal EGS. Surveys assessed subjective changes in symptoms; success was evaluated using a 10-point visual analog scale (VAS) at the final session (10 = most successful). Paired comparisons of responses at baseline and final treatment were evaluated.

RESULTS

Ninety-four patients were followed up through therapy completion. Treatment indications included urinary (89.4%), defecatory (33.0%), and pelvic pain or dyspareunia (30.9%); 44.7% of patients had a combination of indications. Among women with urinary symptoms, the percentage reporting leakage decreased from 92.9% to 79.3% (P = 0.001), leakage at least daily decreased from 69.0% to 39.5% (P < 0.001), daily urgency with leakage decreased from 42.7% to 19.5% (P = 0.001), daily urgency without leakage decreased from 41.5% to 18.3% (P < 0.001), and median VAS rating (0 = not at all, 10 = a great deal) of daily life interference decreased from 5 to 1.5 (P < 0.001). The median success ratings were 8, 8, and 7 for treatment of urinary symptoms, pelvic pain/dyspareunia, and bowel symptoms, respectively.

CONCLUSIONS

An aggressive pelvic rehabilitation program including biofeedback with vaginal EGS had a high rate of self-reported subjective success and satisfaction and should be considered a nonsurgical treatment option in patients with pelvic floor dysfunction.

Electrical stimulation with non-implanted electrodes for overactive bladder in adults

BACKGROUND

Several options exist for managing overactive bladder (OAB), including electrical stimulation (ES) with non-implanted devices, conservative treatment and drugs. Electrical stimulation with non-implanted devices aims to inhibit contractions of the detrusor muscle, potentially reducing urinary frequency and urgency.

OBJECTIVES

To assess the effects of ES with non-implanted electrodes for OAB, with or without urgency urinary incontinence, compared with: placebo or any other active treatment; ES added to another intervention compared with the other intervention alone; different methods of ES compared with each other.

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, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 10 December 2015). We searched the reference lists of relevant articles and contacted specialists in the field. We imposed no language restrictions.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials of ES with non-implanted devices compared with any other treatment for OAB in adults. Eligible trials included adults with OAB with or without urgency urinary incontinence (UUI). Trials whose participants had stress urinary incontinence (SUI) were excluded.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened search results, extracted data from eligible trials and assessed risk of bias, using the Cochrane 'Risk of bias' tool.

MAIN RESULTS

We identified 63 eligible trials (4424 randomised participants). Forty-four trials did not report the primary outcomes of perception of cure or improvement in OAB. The majority of trials were deemed to be at low or unclear risk of selection and attrition bias and unclear risk of performance and detection bias. Lack of clarity with regard to risk of bias was largely due to poor reporting.For perception of improvement in OAB symptoms, moderate-quality evidence indicated that ES was better than pelvic floor muscle training (PFMT) (risk ratio (RR) 1.60, 95% confidence interval (CI) 1.19 to 2.14; n = 195), drug treatment (RR 1.20, 95% 1.04 to 1.38; n = 439). and placebo or sham treatment (RR 2.26, 95% CI 1.85 to 2.77, n = 677) but it was unclear if ES was more effective than placebo/sham for urgency urinary incontinence (UUI) (RR 5.03, 95% CI 0.28 to 89.88; n = 242). Drug treatments included in the trials were oestrogen cream, oxybutynin, propantheline bromide, probanthine, solifenacin succinate, terodiline, tolterodine and trospium chloride.Low- or very low-quality evidence suggested no evidence of a difference in perception of improvement of UUI when ES was compared to PFMT with or without biofeedback.Low- quality evidence indicated that OAB symptoms were more likely to improve with ES than with no active treatment (RR 1.85, 95% CI 1.34 to 2.55; n = 121).Low- quality evidence suggested participants receiving ES plus PFMT, compared to those receiving PFMT only, were more than twice as likely to report improvement in UUI (RR 2.82, 95% CI 1.44 to 5.52; n = 51).There was inconclusive evidence, which was either low- or very low-quality, for OAB-related quality of life when ES was compared to no active treatment, placebo/sham or biofeedback-assisted PFMT, or when ES was added to PFMT compared to PFMT-only. There was very low-quality evidence from a single trial to suggest that ES may be better than PFMT in terms of OAB-related quality of life.There was a lower risk of adverse effects with ES than tolterodine (RR 0.12, 95% CI 0.05 to 0.27; n = 200) (moderate-quality evidence) and oxybutynin (RR 0.11, 95% CI 0.01 to 0.84; n = 79) (low-quality evidence).Due to the very low-quality evidence available, we could not be certain whether there were fewer adverse effects with ES compared to placebo/sham treatment, magnetic stimulation or solifenacin succinate. We were also very uncertain whether adding ES to PFMT or to drug therapy resulted in fewer adverse effects than PFMT or drug therapy alone Nor could we tell if there was any difference in risk of adverse effects between different types of ES.There was insufficient evidence to determine if one type of ES was more effective than another or if the benefits of ES persisted after the active treatment period stopped.

AUTHORS' CONCLUSIONS

Electrical stimulation shows promise in treating OAB, compared to no active treatment, placebo/sham treatment, PFMT and drug treatment. It is possible that adding ES to other treatments such as PFMT may be beneficial. However, the low quality of the evidence base overall means that we cannot have full confidence in these conclusions until adequately powered trials have been carried out, measuring subjective outcomes and adverse effects.

Intracavitary electrical stimulation as treatment for overactive bladder: systematic review

Abstract Introduction: Overactive bladder (OAB) is a clinical diagnosis of irritating urinary symptoms that influence on sufferers' life quality. There are effective treatments described in literature, but most of them present adverse effects. One way of treatment is the use of electrical stimulation, which has been widely used, but studies show varying results. Objective: To verify if intracavitary electrical stimulation can be effective in patients with OAB. Methods: online databases were searched with specific descriptors to find randomized clinical trials on overactive bladder treated with intracavitary electrical stimulation. Only articles with score equal or higher than 5 in methodological PEDro scale were used and those that described intra and / or inter-group P-value. Results: 217 articles were found, but only 6 were analyzed by the selection criteria. The studies show that electrical stimulation promotes the reduction of urinary frequency, urinary incontinence, nocturia, urgency and the number of protectors used, and improvements in maximum cystometric bladder capacity, symptoms of OAB and quality of life. Conclusion: Electrical stimulation was effective in patients with OAB and can be used before any invasive treatment due to none side effects.

Electrical stimulation with non-implanted electrodes for overactive bladder in adults

BACKGROUND

Several options exist for managing overactive bladder (OAB), including electrical stimulation (ES) with non-implanted devices, conservative treatment and drugs. Electrical stimulation with non-implanted devices aims to inhibit contractions of the detrusor muscle, potentially reducing urinary frequency and urgency.

OBJECTIVES

To determine the effectiveness of: ES with non-implanted electrodes compared with placebo or any other active treatment for OAB; ES added to another intervention compared with the other intervention alone; different methods of ES compared with each other.

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 10 December 2014). We searched the reference lists of relevant articles and contacted specialists in the field. We imposed no language restrictions.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials of ES with non-implanted devices compared with any other treatment for OAB in adults. Eligible trials included adults with OAB with or without urgency urinary incontinence (UUI). Trials whose participants had stress urinary incontinence (SUI) were excluded.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened search results, extracted data from eligible trials and assessed risk of bias, using the Cochrane Collaboration's 'Risk of bias' tool.

MAIN RESULTS

We identified 51 eligible trials (3443 randomised participants). Thirty-three trials did not report the primary outcomes of subjective change in OAB symptoms. The majority of trials were deemed to be at low or unclear risk of selection and attrition bias and unclear risk of performance and detection bias. Lack of clarity with regard to risk of bias was largely due to poor reporting.Twenty-three trials (1654 participants) compared ES with no active treatment, placebo or sham treatment. Moderate-quality evidence indicated that OAB symptoms were more likely to improve in people receiving ES than with no active treatment, placebo or sham treatment (relative risk (RR) for no improvement 0.54, 95% confidence interval (CI) 0.47 to 0.63). Moderate-quality evidence indicated that similar numbers of people receiving ES and no active treatment, placebo or sham treatment experienced adverse effects.Eight trials (542 participants) compared ES with conservative treatment. Very low-quality evidence suggested no evidence of a difference between ES and PFMT or PFMT plus biofeedback in OAB symptoms (RR for no improvement 0.79, 95% CI 0.51 to 1.21 and 0.97, 95% CI 0.60 to 1.57 respectively). There was no evidence of a difference between ES and conservative treatment with regard to adverse effects.Sixteen trials (894 participants) compared ES with drug treatment (probanthine, tolterodine, oxybutynin, propantheline bromide, solifenacin succinate, terodiline, trospium chloride, terodiline). Moderate-quality evidence indicated that OAB symptoms were more likely to improve with ES than drug treatment (RR for no improvement 0.66, 95% CI 0.48 to 0.90). Low-quality evidence suggested a greater risk of adverse effects with oxybutynin (RR 1.26, 95% CI 1.07 to 1.49) and with tolterodine (RR 1.51, 95% CI 1.21 to 1.89) than with ES. There was insufficient evidence of a difference between ES and trospium hydrochloride (RR 0.73, 95% CI 0.43 to 1.25).Eight trials (252 participants) compared ES combined with another treatment versus the other treatment alone, two trials (48 participants) compared ES plus conservative treatment with no active treatment, placebo or sham treatment and six trials (361 participants) compared different types of ES. None of these comparisons had sufficient evidence to indicate any differences between the treatment groups in terms of OAB or adverse effects.Moderate-quality evidence suggested that ES improved OAB-related quality of life more than no active treatment, placebo or sham treatment. There was insufficient evidence of any difference between ES and any other treatment with regard to quality of life.There was insufficient evidence to determine if the benefits of ES persisted after the active treatment period stopped.

AUTHORS' CONCLUSIONS

Electrical stimulation appeared to be more effective than both no treatment and drug treatment for OAB. There was insufficient evidence to determine if ES was more effective than conservative treatment or which type of ES was more effective. This review underlines the need to conduct well-designed trials in this field measuring subjective outcomes and adverse effects.

Noxious electrical stimulation of the pelvic floor and vagina induces transient voiding dysfunction in a rabbit survival model of pelvic floor dystonia

PURPOSE

Existing data supports a relationship between pelvic floor dysfunction and lower urinary tract symptoms. We developed a survival model of pelvic floor dysfunction in the rabbit and evaluated cystometric (CMG), electromyographic (EMG) and ambulatory voiding behavior.

MATERIALS AND METHODS

Twelve female adult virgin rabbits were housed in metabolic cages to record voiding and defecation. Anesthetized CMG/EMG was performed before and after treatment animals (n=9) received bilateral tetanizing needle stimulation to the pubococcygeous (PC) muscle and controls (n=3) sham needle placement. After 7 days all animals were subjected to tetanizing transvaginal stimulation and CMG/EMG. After 5 days a final CMG/EMG was performed.

RESULTS

Of rabbits that underwent needle stimulation 7 of 9 (78%) demonstrated dysfunctional CMG micturition contractions versus 6 of 12 (50%) after transvaginal stimulation. Needle stimulation of the PC musculature resulted in significant changes in: basal CMG pressure, precontraction pressure change, contraction pressure, interval between contractions and postvoid residual; with time to 3rd contraction increased from 38 to 53 minutes (p=0.008 vs. prestimulation). Vaginal noxious stimulation resulted in significant changes in: basal CMG pressure and interval between contractions; with time to 3rd contraction increased from 37 to 46 minutes (p=0.008 vs. prestimulation). Changes in cage parameters were primarily seen after direct needle stimulation.

CONCLUSIONS

In a majority of animals, tetanizing electrical stimulation of the rabbit pelvic floor resulted in voiding changes suggestive of pelvic floor dysfunction as characterized by a larger bladder capacity, longer interval between contractions and prolonged contraction duration.

[Multicentric prospective randomized and controlled study assessing effectiveness of intravaginal electrostimulation at home compared to usual care in female patients with urinary incontinence and prior perineal reeducation]

OBJECTIVES

In order to maintain the benefits of perineal reeducation, patients with stress urinary incontinence need to perform self-retraining exercises of the perineal muscles at home. The aim of this randomized prospective multicentric study is to assess the effectiveness of GYNEFFIK(®), a perineal electrostimulator, during this home-care phase.

PATIENTS AND METHODS

Two parallel groups of women with stress urinary incontinence (UI) or with mixed UI (composed predominantly of stress UI), improved by physiotherapy, have followed a self-reeducation program, either with electrostimulation sessions (GYNEFFIK(®) or home perineal electrostimulation [HPES] arm) or with usual care (UC) only, without electrostimulation. The comparison of the two groups was based on the rate of women in which the benefit of the initial perineal reeducation was maintained (defined as the ICIQ and Ditrovie scales' score not worsening) at 2, 4 and 6 months.

RESULTS

A total of 161 patients were analyzed (76 in the HPES arm and 85 in the UC arm). The therapeutic benefit of the initial perineal reeducation at the last available measure (6 months for a wide majority of patients) was maintained in 81.6% in the HPES arm versus 62.4% in the UC arm (P=0.007). This significant difference reflects a significant improvement both in clinical symptomatology and in quality of life. ICIQ score was improved in 44% of patients of HPES arm while it was improved in 14% of patients of UC arm (P<0.001) and daily number of urine leakage decreased of 1.2 leakage in the HPES arm versus 0.1 leakage in UC arm (P<0.05). Likewise, improvement of quality of life was superior in the HPES arm (48% improvement of Ditrovie score versus 19% in the UC group ; P<0.05).

DISCUSSION AND CONCLUSION

Investigator global impression was more favorable in the HPES arm (clinical improvement in 83% of patients versus 68% in the UC arm). At the last measure (i.e. endpoint), the benefit of initial physiotherapy was considered maintained or improved in all patients of the HPES arm while it was reported as worsened in 16.5% of the UC group. Using GYNEFFIK(®) favorably impacts quality of life, particularly physical activity and vitality and decreases emotional consequences of UI (i.e. anxiety and depression score as assessed by HAD scale).

[Multicentric prospective randomized study evaluating the interest of intravaginal electro-stimulation at home for urinary incontinence after prior perineal reeducation. Interim analysis]

OBJECTIVES

Perineal reeducation of stress urinary incontinence is beneficial in 80% of cases. However, patients have to perform self-retraining exercises of the perineal muscles at home, in order to maintain the benefit of the physiotherapy. The aim of this study is to assess the benefit of GYNEFFIK(®), a perineal electro-stimulator, during this home-care phase.

PATIENTS AND METHODS

Women with stress urinary incontinence (UI) or with mixed UI (composed predominantly of stress UI) that responded to physiotherapy were included in this study in two parallel groups. The groups followed a self-reeducation program, with or without GYNEFFIK(®) electro-stimulation sessions. The comparison of the two groups was based on the rate of women for whom the benefit of the initial perineal reeducation was maintained (defined as non-worsening ICIQ and Ditrovie scales' score).

RESULTS

According to the protocol, an interim analysis was performed on 95 patients (i.e. almost half of the expected sample size) who had had at least one evaluation under treatment, among which 44 patients had finished the study. The therapeutic benefit of the initial perineal reeducation was maintained in 87.8% of the GYNEFFIK(®) patient group, while it was maintained in 52.2% (P=0.0001) in the usual care group (i.e. who did not use electro-stimulation).

DISCUSSION AND CONCLUSION

Likewise, patient had a more favorable subjective impression when using GYNEFFIK(®) (83.7% versus 60.0% in the usual care group) as they felt that they improved during the study. In the GYNEFFIK(®) group, no increase in symptoms was reported, whereas almost one out of five patients in the usual care group felt that their condition had worsened.

Electrical stimulation for urinary incontinence in women: a systematic review

BACKGROUND

Electrical stimulation is commonly recommended to treat urinary incontinence in women. It includes several techniques that can be used to improve stress, urge, and mixed symptoms. However, the magnitude of the alleged benefits is not completely established.

OBJECTIVES

To determine the effects of electrical stimulation in women with symptoms or urodynamic diagnoses of stress, urge, and mixed incontinence.

SEARCH STRATEGY

Our review included articles published between January 1980 and January 2012. We used the search terms ″urinary incontinence″, ″electrical stimulation ″, ″ intravaginal ″, ″ tibial nerve ″ and ″ neuromodulation ″ for studies including female patients.

SELECTION CRITERIA

We evaluated randomized trials that included electrical stimulation in at least one arm of the trial, to treat women with urinary incontinence.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed the data from the trials, for inclusion or exclusion, and methodological analysis.

MAIN RESULTS

A total of 30 randomized clinical trials were included. Most of the trials involved intravaginal electrical stimulation. Intravaginal electrical stimulation showed effectiveness in treating urge urinary incontinence, but reported contradictory data regarding stress and mixed incontinence. Tibial-nerve stimulation showed promising results in randomized trials with a short follow-up period. Sacral-nerve stimulation yielded interesting results in refractory patients.

CONCLUSIONS

Tibial-nerve and intravaginal stimulation have shown effectiveness in treating urge urinary incontinence. Sacral-nerve stimulation provided benefits in refractory cases. Presently available data provide no support for the use of intravaginal electrical stimulation to treat stress urinary incontinence in women. Further randomized trials are necessary to determine the magnitude of benefits, with long-term follow-up, and the effectiveness of other electrical-stimulation therapies.

Outcomes of a comprehensive nonsurgical approach to pelvic floor rehabilitation for urinary symptoms, defecatory dysfunction, and pelvic pain

OBJECTIVE

The authors' intent was to determine the clinical efficacy of comprehensive pelvic floor rehabilitation among women with symptoms of pelvic floor dysfunction (PFD).

METHODS

We performed a retrospective analysis of women referred to an academic female pelvic medicine and reconstructive surgery practice for PFD. Data were gathered from the records of 778 women referred for pelvic floor therapy for urinary, bowel, pelvic pain, and sexual symptoms over the course of 4 years.

RESULTS

Patients who completed at least 5 therapy sessions reported a mean symptom improvement of 80% in each of the 3 main categories analyzed, namely, urinary incontinence, defecatory dysfunction, and pelvic pain.

CONCLUSIONS

Comprehensive, nonoperative management of PFD including pelvic floor muscle training, biofeedback, electrogalvanic stimulation, constipation management, behavioral modification, incontinence devices, and pharmacotherapy including vaginal estrogen is effective in the treatment of women with PFD.

Pelvic floor electrostimulation in women with urinary incontinence and/or overactive bladder syndrome: a systematic review

CONTEXT

Electrostimulation (ES) is one of the techniques employed in conservative treatment of urinary incontinence (UI) and/or overactive bladder syndrome (OAB). Nevertheless, there is controversy in the scientific literature regarding its effectiveness as monotherapy.

OBJECTIVE

To evaluate the scientific evidence on ES of the pelvic floor in women with UI and with/without OAB.

EVIDENCE ACQUISITION

A systematic review of clinical trials was carried out in the following databases: PubMed, Cochrane, PEDro, Elsevier (Doyma) and EnFisPo (1980-2011). Quality of study registries was evaluated and information was obtained from those that presented the inclusion criteria established in the review.

EVIDENCE SYNTHESIS

The 27 clinical trials were included in the review: 13 randomized controlled trials, 11 randomized non-controlled trials and 3 non-randomized trials.

CONCLUSION

Most of the clinical trials conclude that ES is effective in the treatment of UI and OAB in women. However, better methodological quality studies are needed to obtain a higher level of scientific evidence and to know the optimal current modality, type and parameters for each type of UI and OAB.

Evaluation of a new disposable "tampon like" electrostimulation technology (Pelviva®) for the treatment of urinary incontinence in women: a 12-week single blind randomized controlled trial

AIMS

To test the null hypothesis that a novel disposable "tampon like" electrostimulation device (Pelviva(®)) is no better than unsupervised pelvic floor muscle exercise for treatment of urinary incontinence in women.

METHODS

Pre/post-intervention assessor blinded, single center RCT. A total of 123 community dwelling self referred women with symptoms of stress, urge, or mixed incontinence were randomly assigned to one of two 12-week duration treatments: Pelviva(®) used for 30 min a day plus unsupervised pelvic floor muscle exercise or unsupervised exercises alone. Outcome measures included ICIQ-UI (primary), ICIQ FLUTSex and global impression of severity and improvement (secondary) completed at recruitment, after 4 weeks of unsupervised exercise and immediately post-treatment. Diary of exercise frequency/type, overall impression, and usage of device was completed mid- and post-treatment.

RESULTS

Pelviva(®) plus exercise produced significantly better outcome than unsupervised exercise alone: 5 points (45%) versus 1 point (10%) for ICIQ-UI (P = 0.014); 67% versus 33% for leak frequency (P = 0.005); 40% versus 20% for leak interference with life (P = 0.018). Incontinence was less bothersome during sex to a greater extent in the Pelviva(®) group (P = 0.026). Women were enthusiastic about the device, found it comfortable/easy to use and experienced no adverse events.

CONCLUSIONS

The Pelviva(®) device plus unsupervised exercise is more successful than unsupervised pelvic floor muscle exercise alone in treating urinary incontinence. The device is easy/comfortable to use, there are no apparent adverse incidents, and women can manage their incontinence in the privacy of their own home. The product will be launched 2013.

Simultaneous perineal ultrasound and vaginal pressure measurement prove the action of electrical pudendal nerve stimulation in treating female stress incontinence

Study Type - Diagnostic (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Pelvic floor muscle training (PFMT) and transvaginal electrical stimulation (TES) are two commonly used forms of conservative treatment for stress urinary incontinence (SUI). PFMT may build up the structural support of the pelvis, but many SUI patients are unable to perform PFMT effectively and its primary disadvantage is lack of long-term patient compliance. TES is a passive treatment that produces PFM contraction and patient compliance with it is good; however, its effect is not as good as that of PFMT when performed correctly. Electrical pudendal nerve stimulation (EPNS) combines the advantages of PFMT and TES and incorporates the technique of deep insertion of long needles. In this study, simultaneous perineal ultrasound and vaginal pressure measurement prove that EPNS can contract the PFM and simulate PFMT. It is shown that EPNS is an alternative therapy for female SUI patients who fail PFMT and TES and the therapy can also be used for severe SUI.

OBJECTIVES

• To prove that electrical pudendal nerve stimulation (EPNS) can contract the pelvic floor muscles (PFM) and simulate pelvic floor muscle training (PFMT). • To show that EPNS is an alternative therapy for female stress urinary incontinence (SUI) that does not respond effectively to PFMT and transvaginal electrical stimulation (TES).

PATIENTS AND METHODS

• Thirty-five female patients with SUI who did not respond effectively to PFMT and TES (group I) were enrolled and 60 other female patients with SUI were allocated to group II (30 patients) and group III (30 patients). • Long needles were deeply inserted into four sacral points and electrified to stimulate the pudendal nerves. Group I and group II were treated by a doctor skilled in performing EPNS and group III, by a doctor unskilled in performing EPNS. • When EPNS was performed in group I, perineal ultrasonographic PFM movements, vaginal pressure (VP) and PFM electromyography were recorded simultaneously. • The therapeutic effects were evaluated according to objective and subjective criteria

RESULTS

• When EPNS was performed correctly, the patient felt strong PFM contractions. Simultaneous recordings in group I showed: B-mode cranio-caudal PFM movements; M-mode PFM movement curves (amplitude: about 1 mm, n= 31); a sawtooth curve of VP changes (2.61 ± 1.29 cmH(2) O, n= 34); and PFM myoelectric waves (amplitude: 23.9 ± 25.3 µV). • If during the EPNS process the electric current was stopped or its intensity was reduced to about 7-12 mA or the two lower needles were drawn back, then the above ultrasonographic PFM movements and VP changes disappeared. • In group I, the incontinence severity and quality of life score was 16.5 ± 4.0 before treatment and decreased to 4.2 ± 4.0 after 27.5 ± 11.9 sessions of treatment (P < 0.01). At the end of treatment, 100% improvement occurred in 16 cases (45.7%). A 2-year follow-up showed that 100% improvement occurred in 14 of cases (40.0%). • In group II, the incontinence severity and quality of life score was 17.1 ± 6.3 before treatment and decreased to 3.5 ± 3.7 after 10 sessions of treatment (P < 0.01) and 100% improvement occurred in 12 cases (40.0%). In group III, the incontinence severity and quality of life score was 17.6 ± 6.3 before treatment and decreased to 10.8 ± 8.2 after 10 sessions of treatment (P < 0.01) and 100% improvement occurred in one case (3.3%). • The post-treatment score was lower and the therapeutic effect was better in group II than in group III (both P < 0.01).

CONCLUSIONS

• EPNS can contract the PFM and simulate PFMT. • EPNS is an alternative therapy for female SUI patients who fail PFMT and TES.

The effect of intravaginal electrical stimulation on the quality of life and changes in function and anatomy of pelvic floor in women with stress urinary incontinence

Introduction: Urinary incontinence (UI), according to the Committee of the International Continence Society Standards, is defined as any involuntary urine loss associated to exertion conditions. This urine loss can be called Stress Urinary Incontinence (SUI) and when the detrusor muscle becomes inactive

Material and methods: The goal of this study was verifying intravaginal electrical stimulation effects on bladder floor mobility, pelvic floor muscles´ width, their contraction ability and the quality of life of 40 women whose age ranged from 35 to 55 and who were diagnosed with Stress Urinary Incontinence disorder. They were split into two groups: Geletro (underwent 16 perineal electrical stimulation sessions) and control group, Gc (no intervention). The variables were respectively evaluated by the following instruments: transvaginal ultrassonography (Toshiba trademark), Phenix electromyographic biofeedback and King´s Health Questionnaire.

Results: The results were bladder floor mobility reduction (Δ% = -9,13%, p=0,0930), width increase on pelvic floor muscles (Δ% = 11,64%, p= 0,2924), both not significant, muscle strength increase due to biofeedback (Δ% =60,49%, p= 0,0001) and to AFA* (Δ% = 24,53%, p=0,0001), and significant decrease of all questionnaire scores: DOM 1 (Δ% = -50,00%, p = 0,000), DOM 2 (Δ% = -55,14%, p= 0,005), DOM 3 (Δ% =-74,98 %, p= 0,002), DOM 4 (Δ% = -73,87%, p= 0,002), DOM 5 (Δ% = -68,91%, p= 0,001), DOM 6 (Δ% = -85,90%, p= 0,000), DOM 7 (Δ% = -72,48%, p= 0,014), DOM 8 (Δ% =-71,88 %, p= 0,030), DOM 9Δ% =-73,29 %, p= 0,023)

Conclusions: The Geletro group in comparison to the Gc which showed that intravaginal electrical stimulation improved the pelvic floor anatomically and functionally and also the quality of life of Geletro group. Stress Urinary Incontinence improvement could only be subjectively demonstrated.

Pelvic floor muscle training for urgency urinary incontinence in women: a systematic review

The objective of this study is to evaluate the effectiveness of existing physiotherapy modalities for the treatment of urge urinary incontinence (UUI). A systematic review was performed for primary studies of physiotherapy techniques for UUI published in English between 1996 and August 2010 in major electronic databases. Only randomized clinical trials that reported outcomes separately for women with UUI were included. Outcomes assessed were reduction in UUI, urinary frequency, and nocturia. Data from 13 full-text trials including the modalities of pelvic floor muscles exercises with or without biofeedback, vaginal electrical stimulation, magnetic stimulation, and vaginal cones were analyzed. The methodologic quality of these trials was fair. Significant improvement in UUI was reported for all physiotherapy techniques except vaginal cone therapy. There are insufficient data to determine if pelvic physiotherapy improves urinary frequency or nocturia. Evidence suggests that physiotherapy techniques may be beneficial for the treatment of UUI.

Avaliação da qualidade de vida e da perda urinária de mulheres com bexiga hiperativa tratadas com eletroestimulação transvaginal ou do nervo tibial

Trata-se de um ensaio clínico prospectivo comparativo que objetivou comparar os efeitos do tratamento com eletroestimulação transvaginal (ET) e do nervo tibial (ENT) sobre a qualidade de vida (QV) e queixas de perda urinária em mulheres com bexiga hiperativa. Participaram 42 pacientes com bexiga hiperativa ou incontinência urinária (IU) mista e foram divididas para tratamento com ET ou ENT. A QV foi avaliada pelo questionário de QV genérico, o Medical Outcomes Study Short Form 36 (SF-36) e um questionário específico para IU, o Incontinence Quality of Life Instrument (I-QOL). Os relatos de perdas urinárias e incômodos ocasionados foram avaliados, respectivamente, por meio do diário miccional de 24 horas e Escala Visual Analógica (EVA). O tratamento foi realizado uma vez por semana, totalizando doze semanas. O grupo da ENT teve melhora significativa em três domínios do I-QOL, na EVA, que avaliou o grau de incômodo causado pela IU e em quatro aspectos do diário miccional. No grupo de ET houve melhora significativa de dois domínios do SF-36, três domínios do I-QOL, na EVA e em quatro aspectos do diário. Houve melhora da QV em ambos os grupos, assim como uma diminuição das queixas de perda urinária, entretanto, o grupo que recebeu ET obteve melhora nos escores em dois domínios do questionário de QV genérico após o tratamento, que teve limitação por aspectos físicos e limitação por aspectos emocionais. O que não ocorreu com o grupo de ENT.

Sensory urgency

Overactive bladder is highly prevalent among the general population. This article describes the definition, theories of causation, diagnostic tools and various treatment options for overactive bladder.

[Conservative treatment of female stress urinary incontinence]

OBJECTIVES

To synthethise evidence based results related to non surgical management for urinary incontinence in women.

MATERIALS AND METHODS

Electronic search in Pubmed, Cinahl, Cochrane Library, National Library for Health.

RESULTS

There were 72 randomized control studies and 8 reviews from the Cochrane Library.

CONCLUSION

Moderate to high levels of evidence suggest that pelvic muscle training and bladder training may resolve urinary incontinence in women. A weight loss program from obesity state improve urinary continence. The effects of electrical stimulation of pelvic floor, oestrogene therapy were inconstant or inhomogeneous. Duloxetine may improve continence and quality of life but it's range in therapeutic algorithm is still to be defined.

A new pelvic muscle trainer for the treatment of urinary incontinence

OBJECTIVE

To describe a new device for home treatment of urinary incontinence (UI) by comparing 3 conservative techniques and monitoring compliance and performance.

METHODS

Thirty-two patients with UI were allocated to 1 of 3 intervention groups: pelvic floor muscle exercises (PFME; n=11) alone; PFME combined with biofeedback (n=10); or PFME combined with electrical stimulation (n=11). The outcomes assessed were: changes in quality of life score (QLS), urodynamic and perineometric parameters, episodes of urine loss, subjective assessment of improvement, and actual compliance and performance with treatment.

RESULTS

Increased pelvic muscle contraction strength (P<0.05), improvement in QLS (P<0.02), and fewer episodes of urine leakage were observed in all 3 groups (P<0.05). Compliance was similar among the groups (P=0.201).

CONCLUSION

All 3 techniques were effective for home treatment of UI, with significant control of symptoms and improved quality of life. The device effectively monitored compliance and performance of exercises.

Maximal functional electrical stimulation as a single treatment: is it cost-effective?

OBJECTIVE

The ideal electrical parameters for maximal functional electrical stimulation (MFES) in the treatment of an overactive bladder have not yet been well established. It has been speculated that unsatisfactory results may be due to a low stimulation intensity and that the number of sessions may also be an outcome-determining factor. Herein, we present the results obtained in a group of consecutively treated patients who were given 10 sessions of MFES at the highest tolerable amplitude.

MATERIAL AND METHODS

A total of 60 patients (29 females, 31 males) with an overactive bladder were treated. All subjects underwent a urodynamic assessment and completed a 48-h micturition chart prior to treatment, immediately after the last session and 3 months after termination of treatment. The patients were thoroughly informed that the result of the treatment depended on the amplitude that they could endure; there was a gradual increase in amplitude to the maximum level that did not cause painful discomfort.

RESULTS

Immediately after termination of the stimulation, almost half of the subjects reported an improvement in their condition. However, few subjects experienced sustained symptom amelioration 3 months post-stimulation. Decreases in micturition frequency and the number of leakage episodes were noted immediately after cessation of treatment but these decreases were no longer significant 3 months post-treatment.

CONCLUSIONS

In this series, although MFES was effective in the short term, the long-term treatment outcome was unsatisfactory. A critical review suggests that outcome success is proportional to the patient's ability and willingness to accept quite a high stimulation intensity or, alternatively, follow-up home treatment. Hence, the implementation of strict primary as well as secondary selection criteria can hopefully identify patients most suitable for MFES. Another lesson to be learnt is that the identification of crucial prerequisites of successful treatment is mandatory before embarking on controlled studies.

Sexual Function in Women with Urinary Incontinence Treated by Pelvic Floor Transvaginal Electrical Stimulation

INTRODUCTION

Women's sexual dysfunctions (WSD) have been commonly associated with urinary incontinence (UI). Women with UI and who scored low on the Female Sexual Function Index (FSFI) showed an improvement in urinary leakage and also in their sexual life following treatment by transvaginal electrical stimulation (TES).

AIMS

To determine the effects of TES in 37 women complaining of UI, of whom 23 also had WSD, and to compare the FSFI scores of women with UI and 43 women not affected by UI who underwent routine urologic evaluation.

METHODS

Thirty-seven women complaining of UI were evaluated by voiding diary and with FSFI before and after 3 months of TES. All had a urogynecologic evaluation and urodynamic study.

MAIN OUTCOME MEASURES

In the voiding diary the women reported the types of liquid they ingested, urinary frequency, and episodes of urgency and urine leakage. The domain scores of the FSFI, including desire, arousal, lubrication, orgasm, satisfaction, and pain, were calculated. TES was conducted for 15-30 minutes, twice a week for 3 months, using biphasic intermittent current with a frequency of 50 Hz for stress UI (SUI) and 20 Hz for urge UI (UUI), and the most tolerable intensity of stimulation.

RESULTS

After TES, only two of the 10 women with UUI experienced a few leakage incidents; patients with SUI were completely dry during TES; and only three reported a few episodes of UI during intense activities. The five patients with mixed UI improved mainly as regards urgency. The FSFI scores of patients complaining of UI showed significantly lower desire and sexual satisfaction, and higher sexual pain than controls. After 3 months, the 23 women affected by WSD, of the 37 participants with UI, reported a remarkable improvement in their sexual life.

CONCLUSIONS

TES was found to be a safe and effective therapy for selected patients affected by mild to moderate UI. Because women with UI also complain of WSD compared with the general female population, an investigation of female sexuality is suggested for these patients.

An evidence-based approach to the evaluation and management of stress incontinence in women

PURPOSE OF REVIEW

The aim of this article is to use evidence-based criteria to review recent publications on the evaluation and management of stress urinary incontinence in women.

RECENT FINDINGS

Longitudinal studies suggest that a familial predisposition towards stress urinary incontinence may exist. There is mounting evidence that cesarean section may play a protective role against pelvic floor damage due to labor, but this continues to be investigated. Objective parameters in the evaluation of stress urinary incontinence, such as questionnaires, pad test, and urodynamic studies, continue to undergo refinements to become more clinically relevant outcome tools. Non-invasive and minimally-invasive therapies for stress urinary incontinence are expanding. The search continues for the optimal non-autologous material in the pubovaginal sling procedure. Despite concerns over the use of synthetic material and better defined early complications, midurethral slings continue to enjoy popularity with short-term and intermediate success.

SUMMARY

Further research into the cause of stress urinary incontinence is necessary. There is still no unified protocol in the evaluation of the condition and its severity. Mid-urethral slings appear to be as efficacious as more established procedures (bladder neck suspensions, pubovaginal slings), but long-term results on safety and efficacy remain scarce.
