The role of muscular re-education by physical therapy in the treatment of genuine stress urinary incontinence

Duloxetine in the Treatment of Stress Urinary Incontinence

Objective:

To review the available literature regarding the use of duloxetine in the treatment of stress urinary incontinence.

Data Sources:

Clinical trials were obtained through a PubMed search (1966–December 2004) with the key words duloxetine, urinary incontinence, and stress.

Data Synthesis:

This article analyzes 5 clinical studies comparing duloxetine with placebo. The randomized, double-blind, multicenter trials were performed in the US and throughout the world and had strict inclusion criteria to enroll only patients with confirmed stess urinary incontinence. All trials showed a statistically significant decrease in incontinence episode frequency of 50–60% for duloxetine compared with a placebo response of 27–40%.

Conclusions:

Duloxetine appears to be an effective treatment for stress urinary incontinence. Additional trials comparing duloxetine with pelvic floor muscle training would better define duloxetine's place in therapy.

[Effect of Kegel exercise to prevent urinary and fecal incontinence in antenatal and postnatal women: systematic review]

PURPOSE

The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence.

METHODS

Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1.

RESULTS

Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity.

CONCLUSION

There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

Evaluation of efficacy of duloxetine in stress urinary incontinence in women

Objective:

The purpose of this study has been to assess the efficacy of duloxetine, a selective inhibitor of serotonin and norepinephrine reuptake, in the treatment of stress urinary incontinence (SUI) in women.

Materials and Methods:

The study included 50 women aged above 18 years with a predominant symptom of stress urinary incontinence (SUI). The case definition included a predominant symptom of SUI with a weekly incontinence episode frequency (IEF) of seven or greater and a positive cough stress test. All the patients received duloxetine 20 mg twice daily for 12 weeks. The primary outcome variables included the IEF and improvement in quality of life. Paired Student's ‘t’ test was used to analyze changes in IEF.

Results:

The improvement with duloxetine treatment was found in 40 out of 50 patients. Remaining 10 patients did not show any improvement with duloxetine and discontinued the treatment. In 40 patients, the mean baseline IEF was 12.5/week. At the end of three months treatment, IEF was six/week. This shows a statistically significant reduction in the IEF. Also, there was a good improvement in quality of life with 65% of patients in the “very much better” and “much better” categories according to PGI-I scale. In the remaining 10 patients, there was no significant improvement after one month of treatment and patients underwent surgery.

Conclusions:

The findings support duloxetine as a potential treatment for women with stress urinary incontinence.

Impact of supervised physiotherapeutic pelvic floor exercises for treating female stress urinary incontinence

CONTEXT AND OBJECTIVE

Urinary incontinence is a public health problem that affects more than 200 million people worldwide. Stress incontinence is the most prevalent type. Pelvic floor muscle exercises have been used for treating it, although there is no consensus regarding their application. The aim of this study was to compare the results from treating female stress urinary incontinence with pelvic floor muscle exercises with or without physiotherapist supervision.

DESIGN AND SETTING

This was a randomized, prospective, controlled trial in the Urogynecology and Vaginal Surgery Sector, Universidade Federal de São Paulo.

METHODS

Forty-four women were randomized to be treated for stress urinary incontinence with pelvic floor exercises for three consecutive months, into two groups: one with and the other without physiotherapist supervision. They were evaluated before and after treatment using a quality-of-life questionnaire, pad test, micturition diary and subjective evaluation. Descriptive analysis was used to evaluate the population. The homogeneity of the two groups was evaluated using the Kruskal-Wallis and Chi-squared tests. The success of the two groups after treatment was evaluated using the Wilcoxon test.

RESULTS

The supervised group showed statistically greater improvement in the pad test, micturition diary and quality of life than did the control group. In the subjective evaluation, only 23.8% of the control group patients were satised with their treatment. In the supervised group, 66.8% of patients did not want any other treatment.

CONCLUSION

Supervised pelvic floor muscle exercises presented better results in objective and subjective evaluations than did unsupervised exercises.

A cross-sectional study of knowledge and practice of pelvic floor exercises during pregnancy and associated symptoms of stress urinary incontinence in North-East Scotland

OBJECTIVES

to establish levels of knowledge about pelvic floor exercises during pregnancy; reported practice of pelvic floor exercises in pregnancy; and prevalence of stress urinary incontinence in a sample of women in the third trimester of pregnancy.

DESIGN

structured cross-sectional interview survey.

PARTICIPANTS

pregnant women over the age of 16 years and more than 30 weeks gestation attending antenatal clinics in North-East Scotland. Of 350 women who agreed to participate, 289 (82.6%) were interviewed between July 1999 and March 2000.

FINDINGS

225 women (77.9%) reported being given or obtaining information about pelvic floor exercises in the current pregnancy. Books were the most frequently mentioned source of information. Midwives were the health professionals most likely to give information about pelvic floor exercises. Younger women, first-time mothers and those from more deprived backgrounds were less likely to report having information about the exercises. A third of women (n=90, 31.1%) said that they would have liked more information about the exercises. Practice of the exercises during pregnancy was reported by just over half the sample (n=156, 54.0%) and more than once a day by 26.3% (n=76). Younger women, and those from more deprived backgrounds, were less likely to report the practice of exercises. No difference was found in reported practice according to parity. More than half (n=157, 54.3%) of the women reported incontinence during the current pregnancy. No relationship was found between reported practice of pelvic floor exercises and stress urinary incontinence.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

the number of women who indicated a desire for more information and the low number who reported practice of the exercises suggest that improvements could be made. The gaps in information provision and practice suggest areas for future health promotion about the exercises, particularly by midwives, as not all women are seen by a physiotherapist during pregnancy. Reported levels of incontinence during pregnancy confirm previous findings and highlight the prevalence of incontinence in pregnancy.

A longitudinal follow up of women in their practice of perinatal pelvic floor exercises and stress urinary incontinence in North-East Scotland

OBJECTIVES

to establish the reported practice of pelvic floor exercises and stress urinary incontinence after delivery.

DESIGN

a longitudinal study using a postnatal postal questionnaire.

PARTICIPANTS

257 women in the North-East of Scotland were sent questionnaires between June and December 2000, 6-12 months after delivery (previously recruited and interviewed during the last trimester of pregnancy). One hundred and sixty-three women responded (63.4%).

FINDINGS

more women reported the practice of pelvic floor exercises after delivery than during pregnancy: 134 (83.2%) compared with 123 (76.4%). Six to 12 months after delivery, 96 (60%) women said that they were still doing the exercises. A third of respondents (n=54, 33.1%) reported stress incontinence at some time since having the baby. Of those reporting incontinence at the time of questionnaire completion, six (19.3%) said the incontinence was moderate or severe, whereas eight (34.7%) reported incontinence once a week or more. Women who had an operative vaginal delivery (forceps or ventouse delivery) were more likely to report the practice of pelvic floor exercises than those having a spontaneous vaginal delivery. No significant difference was found in reported rates of stress incontinence between women who had different modes of delivery. The practice of pelvic floor exercises daily or more often during pregnancy was associated with less reported postnatal incontinence compared with less frequent practice.

KEY CONCLUSIONS

self-reported rates of practice of pelvic floor exercises increased from pregnancy to the immediate postnatal period and subsequently declined. A third of women reported the symptoms of stress incontinence after delivery. Daily or more frequent practice of the exercises during pregnancy may be required in order to prevent postnatal incontinence (although further research is required to confirm this finding).

IMPLICATIONS FOR PRACTICE

midwives should continue to encourage regular and frequent practice of pelvic floor exercises in the postnatal period and beyond. They also need to ask about symptoms of stress incontinence and refer as necessary.

El papel del fisioterapeuta pélvico

Pelvic physical therapy focuses on the prevention and the treatment of all kinds of functional disorders of the abdominal, pelvic and low back region, like urinary incontinence, that is considered as a high prevalent health problem in women, men, children and the elderly. Physical therapy is often considered as the first-choice treatment, due to its non-invasive character, the results in terms of symptom relief, the possibility of combining physical therapy with other treatments, the low risk of side effects and the moderate to low costs. Important restrictions for success might be motivation and perseverance of patient and therapist and the time needed for physical therapy. The armentum of the pelvic physical therapist contains interventions such as physiotherapeutic diagnostics, education and information of patients, pelvic floor muscle (PFM) training, bladder training (BlT), training with vaginal cones, electrical stimulation, biofeedback, etc. In stress incontinence, to improve the extrinsic closing mechanism of the urethra, physical therapy is aimed on strength improvement and coordination of the peri-urethral and pelvic floor muscles. Especially, PFM training is effective. For detrusor overactivity physical therapy aims to reduce or eliminate involuntary detrusor contractions through reflexinhibition. Here, electrical therapy appears to be an effective intervention. In mixed urinary incontinence the physiotherapeutic diagnostic and therapeutic process focuses on the predominant factors. Radical prostatectomy is the most important cause of incontinence in men. An adequate program of PFM training, after radical prostatectomy, decreases the duration and the extent of incontinence and improves the quality of life.

CONCLUSION

physical therapy is in many cases of incontinence an effective treatment option.

The short-term effects of physical therapy in different intensities of urodynamic stress incontinence

PURPOSE

The aim of this study was to investigate and compare the short-term effects of a physical therapy program in patients with different intensities of urodynamic stress urinary incontinence (USI).

SUBJECTS AND METHODS

48 patients with USI were assigned to three groups according to the intensity of their incontinence: group I: 0-2 g (n = 17), group II (mild intensity: >2-10 g, n = 16) and group III (moderate intensity: >10 g, n = 15) as determined by the 1-hour pad test. A physical therapy program composed of Kegel exercises and interferential current was applied to all patients for duration of 5 weeks, with a total of 15 sessions. The number of pads used a day, frequency of voiding (times/day), amount of urinary leakage according to the 1-hour pad test (mg), severity of complaint (as centimeters on visual analogue scale) and pelvic floor muscle strength (cm Hg) were evaluated. Pre-treatment and post-treatment values of these data were compared in each group and among groups.

RESULTS

Analyses of the data indicated that the number of pads used a day, frequency of voiding and amount of urinary leakage decreased and pelvic floor muscle strength increased significantly in each group (p < 0.05). Cure in USI was found in 88% of subjects in group I and 18% of subjects in group II (mild intensity). None of the patients in group III (moderate intensity) showed a cure effect.

CONCLUSION

This physical therapy program was found to be more effective in mild and moderate intensities than severe USI.

Program development for promoting adherence during and after exercise therapy for urinary incontinence

This paper presents the development process of a health education program to promote adherence to a pelvic floor muscle exercise (PFME) therapy for women with urinary incontinence (UI). The development process started with a needs assessment phase in which the health problem, health-related quality of life, and behavioral and environmental determinants were assessed. Guided by the intervention mapping (IM) approach, program objectives were formulated and, on the basis of both empirical and theoretical data, intervention methods for influencing determinants of adherence to PFME therapy were chosen and translated into practical strategies. This information was assimilated to a transparent description of the program design. The theoretical rationale of the program was based on the transtheoretical model, the self-regulation theory and principles of targeted communication and sex-specific health care.

A 10-year follow-up after Kegel pelvic floor muscle exercises for genuine stress incontinence

OBJECTIVE

To determine the outcome 10 years after an individual course of pelvic floor muscle (PFM) exercises for genuine stress incontinence.

PATIENTS AND METHODS

Postal questionnaires were sent to 52 women who had undergone PFM training 10 years earlier, and their medical files were reviewed. The main outcome measures were the patients' self-assessment of therapy outcome, the frequency of PFM exercises at home, and the demand for surgery after physiotherapy.

RESULTS

Forty-five women (87%; mean age 61 years) were suitable for analysis. On completing the course of PFM exercises, physiotherapy had been apparently successful in 24 (53%), and considered to have failed in 21 women (47%). Sixteen of the 24 successful patients remained satisfied with their urinary continence when reassessed 10 years later; two women had undergone surgery (8%). In the group where physiotherapy initially failed, five women (24%) who had not had surgery claimed to be much improved; 13 women (62%) had undergone surgery. Overall, women in whom the conservative treatment of stress incontinence had produced an improvement over the 10 years had practised PFM exercises more regularly (76%) than the others (55%; not significant). However, an active voluntary PFM contraction before a sudden intra-abdominal pressure rise ('perineal lock') appeared to be responsible for most of the success.

CONCLUSIONS

When PFM training is initially successful, there is a 66% chance that the favourable results will persist for at least 10 years.

Conservative treatment of stress urinary incontinence in women: a systematic review of randomized clinical trials

OBJECTIVE

To assess the efficacy of physical therapies for first-line use in the treatment and prevention of stress urinary incontinence (SUI) in women, using a systematic review of randomized clinical trials (RCTs).

MATERIALS AND METHODS

A computer-aided and manual search for published RCTs investigating treatment and prevention of SUI using physical therapies, e.g. pelvic floor muscle (PFM) exercises, with or without other treatment modalities, were carried out. The methodological quality of the included trials was assessed using criteria based on generally accepted principles of interventional research.

RESULTS

Twenty-four RCTs (22 treatment and two prevention) were identified; the methodological quality of the studies included was moderate and 11 RCTs were of sufficient quality to be included in further analysis. Based on levels-of-evidence criteria, there is strong evidence to suggest that PFM exercises are effective in reducing the symptoms of SUI. There is limited evidence for the efficacy of high-intensity vs a low-intensity regimen of PFM exercises. Despite significant effects of biofeedback after testing as an adjunct to PFM exercises, there is no evidence that PFM exercises with biofeedback are more effective than PFM exercises alone. There is little consistency (of stimulation types and parameters) in the studies of electrical stimulation, but when the results are combined there is strong evidence to suggest that electrostimulation is superior to sham electrostimulation, and limited evidence that there is no difference between electrostimulation and other physical therapies. In the prevention of SUI the efficacy of PFM exercises, with or without other adjuncts, is uncertain.

Pelvic floor exercises versus vaginal weight cones in genuine stress incontinence

OBJECTIVE

To compare pelvic floor exercises and vaginal weight cones in the treatment of genuine stress incontinence.

STUDY DESIGN

Randomised controlled trial.

METHODS

Sixty ambulatory and fit white women (mean age 56 years) with urinary stress incontinence, treated by a single physiotherapist as outpatients during twelve weeks. Thirty women were allocated to a weekly session of pelvic floor exercises. Thirty were allocated to using cones, they were seen every two weeks.

OUTCOME MEASURES

Objective: stress test, vaginal squeezing capacity. Subjective: urinary diary, visual analogue scales.

RESULTS

Characteristics of both study groups were comparable. Unfortunately, there was an early withdrawal of fourteen (47%) women in the group treated with cones, and none in the other group. Therefore the pelvic floor exercise group was compared not only with the group intended to be treated with cones, but also with the selected group that only received cone therapy. No statistically significantly differences in outcome measures were found between the groups: 53% in the group assigned to pelvic floor exercises and 57% into the group assigned to cones, of which 50% in the group actually treated with cones, considered themselves as cured or improved to a significant degree. Long-term follow-up was not possible as all cone users refused continued exercises with cones once the twelve weeks had ended.

CONCLUSION

Pelvic floor exercises and cones are equally effective in the treatment of genuine stress incontinence. Cones are cost and time saving. However, the low patient compliance with the cones importantly limits its clinical applicability, especially in the long run. Therefore, we do not recommend the use of cones.

The role of estrogen replacement therapy in the management of urinary incontinence and urinary tract infection in postmenopausal women

The hormonal changes associated with normal aging and menopause may contribute to the development of urinary disorders including both urinary incontinence and urinary tract infections. Estrogen replacement therapy has been used successfully in the treatment of both of these disorders in postmenopausal women. Although the selection of specific treatment modalities should be tailored to the individual patient, hormonal replacement should be considered a viable conservative treatment option for many older women with urinary complaints. Future research will help to delineate the most effective route of administration and type of estrogen used in treating these complaints.

A prospective, randomized controlled trial of inpatient versus outpatient continence programs in the treatment of urinary incontinence in the female

Seventy-four patients presenting with a mixed pattern of urinary symptoms were randomly allocated to undergo either inpatient or outpatient continence programs as initial treatment, without prior urodynamic investigation. Both programs consisted of physiotherapy, bladder retraining, fluid normalization, dietary advice and general support and advice. Nine out of 39 in the outpatient group and 8 out of the 35 of the inpatient group failed to complete the study. There was a significant decrease in frequency, nocturia, number of incontinent episodes and visual analog scores for both groups. In addition the outpatients had a significant reduction in loss on pad testing, and a significantly greater improvement in their visual analog score. In each group 63% were cured or improved to the extent that they did not require further treatment. Staff costs per outpatient were half those for an inpatient. We conclude that outpatient conservative treatment as detailed above is a successful first-line treatment of urinary incontinence in women. It is as successful and possibly better than inpatient treatment, and is significantly cheaper.

Efficacy of biofeedback, when included with pelvic floor muscle exercise treatment, for genuine stress incontinence

We performed a randomized clinical trial on the efficacy of physical therapy on genuine stress incontinence.

STUDY OBJECTIVE

"Is a physical therapeutical training program (pelvic floor muscle training) combined with biofeedback, more effective than the same program without biofeedback in patients with mild or moderate stress incontinence?" Forty-four patients were referred by a general practitioner or a urologist. After informed consent, 40 patients were randomized in an exercises and biofeedback group (BF), or treated with exercises exclusively (pelvic floor muscle training = PFMT). After a diagnostic phase of 1 week every patient received twelve treatment sessions, three times weekly. The primary measure of effect, the quantity of involuntary urine loss, was measured with the 48 hours PAD test (Inco-test Mölnlycke). Before every treatment session the Symptoms questionnaire was filed out by the patient and the Patient dairy was controlled. The data of the trial were analysed according to the principal of intention to treat. During the trial there was 100% compliance. There were no drop-outs. Both treatment modalities appeared to be effective. After twelve treatment sessions there was a mean improvement of +/- 55% (P = 0.00) in both treatment groups, measured by the primary measure of effect. In the group with BF this improvement was already realized after six treatment sessions (P = 0.01). Yet, the difference between BF and PFMT faded to reach significance at six treatment sessions (P = 0.08). Although differences in treatment effects between both groups were not significant, our findings suggest that adding biofeedback to pelvic floor muscle exercises might be more effective than pelvic floor muscle exercises alone after six treatments.

Conservative therapy of female genuine stress incontinence with vaginal cones

OBJECTIVE

The objective was to analyse urodynamic data before and after conservative treatment with vaginal cones.

STUDY DESIGN

The design was an open clinical study and was carried out at the Urogynaecology Unit of the University women's hospital. Eighteen women with genuine urinary stress incontinence were treated with vaginal cones for 6 weeks. Cystometry was performed before and after conservative therapy. The patients' subjective improvement and the urodynamic data have been compared. The Mann-Whitney U-test was used for statistical analysis.

RESULTS

Of eighteen women with cone therapy, eight were continent after 6 weeks and showed a significant increase of the dynamic urethral closure pressure. Seven patients reported a subjective improvement, and in three women no change of stress incontinence was observed Colposuspension was performed at a later date in these three cases.

CONCLUSION

Vaginal cone therapy is a successful method to cure mild female stress incontinence and has the advantage of avoiding incontinence operation. Therapeutic success can be assessed by urodynamic evaluation.

Pelvic floor muscle exercises: 5 years later

OBJECTIVES

To determine the outcome of pelvic floor muscle exercises for genuine stress incontinence after 5 years.

METHODS

Questionnaires were sent to 48 women, mean age 57 years, with troublesome stress incontinence treated as outpatients by a skilled female physiotherapist to elucidate a self-assessment of therapy outcome and to determine patients' compliance concerning fulfillment of home exercises and attitude toward physiotherapy. Patients' self-assessment responses indicated cured, much improved, some improvement, or unchanged/worse and incidence of anti-incontinence surgery after physiotherapy.

RESULTS

The overall cure/much improvement rate for physiotherapy at the end of therapy was 54% and 5 years later it was 58% (confidence interval, 43 to 72); (P = 1.000, binomial test). Thirteen women (27%) underwent surgery. Seven unoperated women (15%) showed only some improvement or relapse and may have been undertreated. Severity of symptoms before therapy was an important factor in therapy outcome but not in therapy maintenance. Frequency of home practicing was comparable in those who had surgery afterward and those who had not. There was no clear linear relationship in long-term effect and frequency of home practicing. Severity of symptoms and behavioral changes bias this relationship. Physiotherapy was well tolerated, as 73% would still prefer it as first choice. Pelvic floor muscle exercises were recommended to friends or relatives by 77% of the patients.

CONCLUSIONS

Once a certain level of incontinence is established with pelvic floor muscle exercises, that level is maintained over 5 years.
