Differentiating stress urinary incontinence from urge urinary incontinence.

Urinary incontinence (UI) is any involuntary leakage of urine and can be further defined according to the patient's symptoms or complaints. Stress urinary incontinence (SUI) is the complaint of involuntary leakage on effort or exertion, or on sneezing or coughing. Urge urinary incontinence (UUI) is characterized by the complaint of involuntary leakage accompanied by or immediately preceded by urgency. Mixed urinary incontinence (MUI) is the presence of both SUI and UUI symptoms. In order to effectively treat UI, an accurate diagnosis is necessary since treatment of SUI or UUI is very different. Assessment obtaining a detailed medical history includes making general assessments taking into account quality of life (QoL), performing an appropriate physical examination with cough stress test; and simple investigations namely a urinary diary, urine analysis and post-void residual assessment and, occasionally, simple urodynamics. These assessments should suffice to commence conservative treatment. Multichannel urodynamics are required in patients presenting with more complicated UI and prior to surgery.

Efficacy and safety of a neurokinin-1 receptor antagonist in postmenopausal women with overactive bladder with urge urinary incontinence.

PURPOSE: Urge urinary incontinence is the involuntary leakage of urine commonly occurring in older adults, particularly women. Preclinical evidence suggests that urge urinary incontinence may occur due to up-regulation of tachykinin mediated bladder/spinal reflex signaling. This study tested the hypothesis that aprepitant, a neurokinin-1 receptor antagonist, may be efficacious in the treatment of urge urinary incontinence. MATERIALS AND METHODS: This was a double-blind, randomized, placebo controlled, parallel group pilot study in which postmenopausal women with a history of urge urinary incontinence or mixed incontinence (with predominantly urge urinary incontinence) were assigned to receive a 160 mg capsule of aprepitant (61) or placebo (64) once daily for 8 weeks. The primary end point was percent change from baseline in average daily micturitions assessed by a voiding diary. Secondary end points included average daily total urinary incontinence and urge urinary incontinence episodes, and urgency episodes. RESULTS: Aprepitant significantly decreased the average daily number of micturitions compared with placebo at 8 weeks. The between-group treatment difference expressed as percent change from baseline was -6.8%, 95% CI (-12.5, -1.1) (p = 0.019). The average daily number of urgency episodes was also significantly reduced compared to placebo (p = 0.049). The average daily number of urge urinary incontinence and total urinary incontinence episodes were also reduced, although the difference was not statistically significant. Aprepitant was generally well tolerated and adverse experiences were generally mild. CONCLUSIONS: Results of this initial study suggest that neurokinin-1 receptor antagonism may represent a novel therapeutic approach to treating overactive bladder syndrome.

A review of the quality-of-life aspects of urinary urge incontinence.

Urinary incontinence (UI) is prevalent and costly, occurring in 15 to 30% of the US population over the age of 60 years. Among people aged 15 to 64 years, UI occurs in 1.5 to 5% of men and 10 to 25% of women. Severe incontinence occurs in 6% of the general US population, and it is estimated that $US10 billion per year is spent in direct costs alone on care for these patients. This review presents a description of the various types of UI and describes the prevalence and costs of the condition. In addition, 3 approaches to assessing the impact of UI on quality of life are discussed, namely generic measures, disease-specific measures and qualitative approaches. We also review papers on UI and sexual functioning, UI in men, and some aspects of treatment. The review was conducted in the process of developing a new disease-specific measure for urinary urge incontinence (UUI). In general, the literature suggests that UUI has a greater impact than stress incontinence on quality of life, and that UI affects social and psychological functioning more than physical functioning. Only in a minority of individuals is the impact of UI disabling; however, most individuals with UI show significant reduction in their social functioning. Several studies suggest that the impact of UI is not solely a function of its severity, but also depends on individual coping abilities. Some studies also indicate that the social problems associated with UI grow with time, but it is not clear if that is a function of increasing severity of the condition, or the particular adaptations required for coping with this problem. An important distinction appears to be the ability of individuals to avoid public notice of their condition because of uncontrolled accidents. In summary, there is a need for a new measure of the quality-of-life impact of UUI that is based on the literature and on in-depth interviews with patients.

Solifenacin: as effective in mixed urinary incontinence as in urge urinary incontinence.

Patients with mixed urinary incontinence (MUI) are frequently treated with antimuscarinic therapy, despite little data being previously published for this patient group. We present a subgroup analysis of patients with overactive bladder syndrome, assessing the efficacy of once-daily solifenacin succinate in patients with MUI (n = 1041) or urge urinary incontinence (UUI; n = 1648) only. A greater proportion of patients receiving solifenacin achieved resolution of incontinence in both the MUI and UUI groups (MUI: 5 mg = 43%, 10 mg = 49%; UUI: 5 mg = 55%, 10 mg = 54%) compared with patients receiving placebo (MUI 33%, UUI 35%). Baseline to endpoint improvements in all other symptoms were statistically significant vs placebo for both solifenacin doses in both cohorts. The incidence of adverse events was comparable between the MUI and UUI cohorts. This analysis shows that once-daily solifenacin was as effective and well tolerated in patients with MUI as in patients with UUI.

Management of refractory urinary urge incontinence following urogynecological surgery with sacral neuromodulation.

AIMS: We sought to explore our patient outcomes utilizing sacral neuromodulation in the management of refractory urinary urge incontinence following urogynecological surgical procedures. METHODS: A total of 25 women with urinary urge incontinence following urogynecological surgery were selected for SNS therapy and retrospectively analyzed. All patients completed a comprehensive urological evaluation. Clinical data was recorded to determine outcomes and identify parameters that would be predictive of response to neuromodulation. Outcomes were determined via subjective patient questionnaire and graded as follows: significant response (> or =80% improvement), moderate response (> or =50% and <80% improvement), and poor response (<50% response). RESULTS: Nineteen patients had a previous pubovaginal sling (10 with concomitant pelvic prolapse repair), 3 a previous retropubic suspension, and 3 a transperitoneal vesicovaginal fistula repair. Urethrolysis was performed in 4 patients to alleviate bladder outlet obstruction prior to sacral neuromodulation. Mean patient age was 59.8 years and length of follow-up was 7.2 months. Twenty-two women (88%) had the IPG placed during a Stage 2 procedure. Twenty patients maintained at least a 50% improvement in clinical symptoms at last follow-up and 6 patients were continent. Overall, the number of pads/day improved from 4.2 to 1.1 (P < 0.001). There were no significant differences in response to neuromodulation based upon age, duration of symptoms, type of surgery, or urodynamic parameters. CONCLUSION: Sacral neuromodulation appears to be an effective therapy in patients with refractory urge incontinence following urogynecological surgery. Larger prospective studies with longer follow-up are needed to assess the durability of this therapeutic modality.

Sacral neuromodulation for the treatment of refractory urinary urge incontinence after stress incontinence surgery.

OBJECTIVE: This study was undertaken to evaluate the response to sacral neuromodulation in women with refractory, nonobstructive urinary urge incontinence after stress incontinence surgery. STUDY DESIGN: We reviewed the medical records of women in whom sacral neuromodulation was performed for worsening or de novo urinary urge incontinence after a stress incontinence procedure. All patients had undergone preliminary test stimulation. Demographics, surgical and urogynecologic history, including bladder diary and pad weight test, and urodynamic parameters were evaluated. RESULTS: Of 34 women, 22 (65%) responded to the test stimulation and underwent permanent lead implant. There was no difference between responders and nonresponders with respect to type of stress incontinence surgery. Incontinence or urodynamic parameters were not different between responders and nonresponders. Factors that were predictive of a positive response were women aged less than 55 years (P = .01), the test stimulation performed within 4 years of the stress incontinence procedure (P = .01), and evidence of pelvic floor muscle activity (P = .03). CONCLUSION: Sacral neuromodulation is a viable option for the treatment of refractory urinary urge incontinence that occurs after stress urinary incontinence surgery. Older women with no pelvic floor activity who are remote from their incontinence surgery may have a suboptimal response.

Intrafascial versus extrafascial abdominal hysterectomy: effects on urinary urge incontinence.

Our aim was to evaluate urinary urge incontinence following intrafascial and extrafascial abdominal hysterectomies in a prospective randomized study. Women scheduled for total abdominal hysterectomy were randomized to the extrafascial (n=38) and the intrafascial techniques (n=42). The groups were controlled for demographic variables, obstetric and gynecologic history, uterine size, indications for hysterectomy, and preoperative hemoglobin values. Short-term surgical morbidity and presence of urge incontinence defined as urodynamically established detrusor overactivity at the end of 12 months were the main outcome measures. Major surgical morbidity did not differ between the two groups. Percentages of women with urge incontinence at the end of the follow-up period were also similar. However, when women with pre-existing urge incontinence were evaluated separately, there was a trend towards the intrafascial operation to be associated with more urge-incontinence-free patients at the end of the follow-up period ( p=0.06, borderline significant). As a result, short-term surgical morbidity seems to be similar across the intrafascial and extrafascial techniques of abdominal hysterectomy. The effects of intrafascial abdominal hysterectomy on women presenting with urge incontinence in the preoperative period merit further investigation.

Oxybutynin for treatment of urge urinary incontinence and overactive bladder: an updated review.

Urge urinary incontinence (UUI) and overactive bladder are common conditions often associated with profound impairment of the health and quality of life of the patient. Antimuscarinic medications have been the mainstay of treatment for these disorders. Oxybutynin hydrochloride, one of the most widely used antimuscarinic agents, has attracted considerable interest from both clinicians and pharmacologists over the last three decades. Although efficacy of this drug has been proven to be high, its use is limited by antimuscarinic adverse effects, possibly related to its active metabolite N-desethyloxybutynin (N-DEO). The extended-release form of oxybutynin uses a push-pull osmotic release system which has significantly improved its tolerability and safety profile. A transdermal transport system has also been developed, bypassing the first-pass metabolism in the liver and gut. This system is associated with significant reduction in the production of the primary metabolite and additional improvement in the tolerability profile of the drug. Intravesical instillation of oxybutynin has been reported although the efficacy and safety of this delivery system has yet to be determined. This article comprehensively reviews the contemporary literature on the pharmacology, clinical efficacy and adverse reactions of oxybutynin in its various delivery forms, and compares them to other frequently used medications for UUI and overactive bladder.

[New options in pharmacological treatment of urge urinary incontinence in women].

OBJECTIVE: The aim of this paper is to provide a brief update review of current pharmacological agents used to treat women with urge incontinence. DESIGN: Review article. SETTINGS: Gynecological and Obstetric Clinic, 1. LF UK and VFN, Prague. RESULTS: Urge urinary incontinence is the condition characterized by the involuntary loss of urine accompained by a strong desire to void. Urge incontinence is often due to detrusor instability, although the instability of the detrusor bladder muscle cannot be demonstrated clinically but through cystomery. Sensory urge incontinence is the involuntary loss of urine associated with urgency and a strong desire to void urine immediately due to the hypersensitivity of the bladder and urethral sensory receptors. The mainstay treatment for this common form of incontinence is conservative treatment. There are two forms of conservative treatment: behavioural techniques and pharmacotherapy. The urge urinary incontinence is most successfully treated by a drug therapy. Anticholinergic drugs and anticholinergic antispasmodic drugs are the primary pharmacologic treatment for this condition, although the usefulness of this agent has been limited by a lack of selectivity for the bladder, which gives rise to frequent, bothersome side effect (dry mouth, constipation, blurred vision, etc.) For these reasons, tolterodine was developed as the first antimuscarinic agent specifically targeted for the treatment of the urge urinary incontinence. This agent has demonstrated a bladder-selective profile in vivo, leading to a more pronunced and longer lasting effect on the bladder than on salivation in humans.

Treatment of refractory urge urinary incontinence with sacral spinal nerve stimulation in multiple sclerosis patients.

BACKGROUND: Urge urinary incontinence in multiple sclerosis patients is usually due to detrusor hyperreflexia. Patients who do not respond to conservative measures such as anticholinergics, with or without clean intermittent catheterisation, are difficult to manage. METHODS: We applied electrical stimulation to the S3 sacral spinal nerves with the aim of activating afferent somatic nerve fibres. Stimulation of these fibres can inhibit the micturition reflex. An S3 electrode coupled to a subcutaneously placed pulse generator was implanted in four women who had shown a good response during temporary stimulation via a percutaneously placed wire electrode. All patients were followed for at least 2 years. FINDINGS: The number of leakage episodes decreased from a mean of 4 to 0.3 per 24 h. Two patients were completely dry. The hyperreflexia disappeared in one, improved in two, and got worse in one patient. The urodynamic result in the last patient may be explained by clinical progression of the multiple sclerosis. INTERPRETATION: Chronic stimulation of the S3 sacral spinal nerve by an implantable neuroprosthesis is a promising treatment option for selected multiple sclerosis patients with refractory urge incontinence.

Behavioral vs drug treatment for urge urinary incontinence in older women: a randomized controlled trial.

CONTEXT: Urinary incontinence is a common condition caused by many factors with several treatment options. OBJECTIVE: To compare the effectiveness of biofeedback-assisted behavioral treatment with drug treatment and a placebo control condition for the treatment of urge and mixed urinary incontinence in older community-dwelling women. DESIGN: Randomized placebo-controlled trial conducted from 1989 to 1995. SETTING: University-based outpatient geriatric medicine clinic. PATIENTS: A volunteer sample of 197 women aged 55 to 92 years with urge urinary incontinence or mixed incontinence with urge as the predominant pattern. Subjects had to have urodynamic evidence of bladder dysfunction, be ambulatory, and not have dementia. INTERVENTION: Subjects were randomized to 4 sessions (8 weeks) of biofeedback-assisted behavioral treatment, drug treatment (with oxybutynin chloride, possible range of doses, 2.5 mg daily to 5.0 mg 3 times daily), or a placebo control condition. MAIN OUTCOME MEASURES: Reduction in the frequency of incontinent episodes as determined by bladder diaries, and patients' perceptions of improvement and their comfort and satisfaction with treatment. RESULTS: For all 3 treatment groups, reduction of incontinence was most pronounced early in treatment and progressed more gradually thereafter. Behavioral treatment, which yielded a mean 80.7% reduction of incontinence episodes, was significantly more effective than drug treatment (mean 68.5% reduction; P=.04) and both were more effective than the placebo control condition (mean 39.4% reduction; P<.001 and P=.009, respectively). Patient-perceived improvement was greatest for behavioral treatment (74.1% "much better" vs 50.9% and 26.9% for drug treatment and placebo, respectively). Only 14.0% of patients receiving behavioral treatment wanted to change to another treatment vs 75.5% in each of the other groups. CONCLUSION: Behavioral treatment is a safe and effective conservative intervention that should be made more readily available to patients as a first-line treatment for urge and mixed incontinence.

Detrusor overactivity and urge urinary incontinence following trans obturator versus midurethral slings.

AIMS: To compare the rates of resolution of detrusor overactivity (DO) and subjective urge urinary incontinence (UUI) as well as de novo DO and UUI between the Monarc, TVT, and SPARC midurethral sling procedures. METHODS: Two hundred and seventy-six subjects with urodynamic stress or mixed urinary incontinence underwent retropubic midurethral slings (TVT, N = 99; SPARC, N = 52) or transobturator slings (Monarc, N = 125). All evaluable subjects had a routine office evaluation, subjective assessment of UUI, and multichannel urodynamic testing pre- and 3 months postoperatively. Comparisons were made using Student's t-test, ANOVA, McNemar's test, and Chi-Square test where appropriate. Multivariate logistic regression was performed to detect possible confounding factors such as sling type, and differences in concomitant surgical procedures. RESULTS: De novo subjective UUI differed significantly between the Monarc and the other two slings (33% TVT vs. 8% Monarc vs. 17% SPARC, P = 0.04). Fourteen to Sixteen percents of patients with preoperative UUI who underwent TVT or SPARC had worsening of their UUI symptoms while only 6% of the Monarc group did (P = 0.02). There was no difference in rates of resolution of DO among the three groups (40% vs. 48% vs. 32%, P = 0.39) or de novo DO (32% vs. 22% vs. 22%, P = 0.64) at 3 months. CONCLUSIONS: Patients who undergo transobturator procedures have significantly lower rates of de novo UUI than those who undergo midurethral sling procedures. Rates of resolution of DO, UUI, and de novo DO do not differ between groups.

A short-term, multicenter, randomized double-blind dose titration study of the efficacy and anticholinergic side effects of transdermal compared to immediate release oral oxybutynin treatment of patients with urge urinary incontinence.

PURPOSE: We compared the short-term efficacy, safety and tolerability of transdermal versus oral oxybutynin in adults with urge urinary incontinence. MATERIALS AND METHODS: Volunteers with detrusor instability currently responding to oral immediate release oxybutynin were enrolled in our study. Those patients presenting with recurrence of incontinent symptoms after a 2-week washout underwent confirmatory cystometrogram with subsequent randomization to transdermal or oral treatment. Matching active and placebo medications included matrix patches applied twice weekly and capsules taken 2 or 3 times daily. Dose titration was based on anticholinergic symptoms. Outcome measures included comparison of baseline to 6 week changes in incontinence episodes on a 3 day urinary diary, a visual analog scale for efficacy and anticholinergic symptoms reported on a questionnaire. Safety monitoring included adverse events and skin tolerability of the transdermal system. RESULTS: A total of 76 patients were enrolled and 74 completed at least 4 weeks of treatment. Mean age in the transdermal and oral groups was 64 and 63 years, and 87% and 97% were female, respectively. Daily incontinent episodes decreased in the transdermal and oral groups (7.3 to 2.4 [66%] and 7.4 to 2.6 [72%], respectively, p = 0.39). The visual analog scale reduction in urinary leakage improved from washout in both groups (p <0.0001) with no difference between them (p = 0.9). Dry mouth occurred in significantly fewer patients in the transdermal (38%) compared with those in the oral group (94%, p <0.001). Of the patients in the transdermal group 67% noticed a reduction in dry mouth severity compared with previous oral treatment, and 90% had none or mild skin erythema. CONCLUSIONS: Transdermal delivery of oxybutynin resulted in comparable efficacy and a significantly improved anticholinergic side effect profile compared with oral administration in adults with urge urinary incontinence.

The effect of botulinum-A toxin on patients with severe urge urinary incontinence.

PURPOSE: We determined the effect of 150 units of botulinum-A toxin (Botox, Allergan, Irvine, California) on subjects with severe urge urinary incontinence (UUI). MATERIALS AND METHODS: This was an open label uncontrolled clinical trial. Subjects were recruited from the female urology and urogynecology clinics at Duke University. Inclusion criteria included evidence of UUI on 3-day bladder diary, a 24-hour pad weight of 100 gm or greater, absent or minimal stress leakage, absent detrusor dysfunction, and a history of failed anticholinergic and physical therapies. Exclusion criteria included evidence of a urinary tract infection, or other correctable or neurological etiology for UUI. The detrusor of each subject was injected with 150 units of botulinum-A toxin. Evaluations were performed at 2 weeks, 6 weeks, 3 months and 6 months after injection. Outcome measures included daily incontinence episodes, Urogenital Distress Inventory and the Incontinence Impact Questionnaire, 24-hour pad weights, daily pad usage and urinalysis at all visits. Urodynamic studies were performed at the 6-week and 3-month visits. RESULTS: Three subjects had uncomplicated urinary tract infections during followup. No other adverse effects occurred. Statistically and clinically significant decreases greater than 50% were seen in virtually all outcome measures at all visits up to 3 months. Most subjects showed signs of recurrent UUI by 6 months. All subjects reported remarkable subjective improvement in incontinence. No significant changes in maximal cystometric capacity, maximal detrusor pressure, peak flow or post-void residual volumes were seen. CONCLUSIONS: Botulinum-A toxin can significantly decrease urge urinary incontinence and improve quality of life for 3 months after injection. Additional studies are needed to determine ideal doses, dosing intervals, safety and cost-effectiveness of this therapy.

A health related quality of life measure for use in patients with urge urinary incontinence: a validation study.

OBJECTIVE: Urge incontinence has substantial impact on health related quality of life (HRQOL). The purpose of this research was to test the psychometric properties of the Urge-Incontinence Impact Questionnaire (U-IIQ) and Urge-Urinary Distress Inventory (U-UDI). METHODS: The U-IIQ and the U-UDI were incorporated in a single arm study of an investigational once-a-day formulation of oxybutynin (Ditropan XL) for urge incontinence. The U-IIQ contains 7 scales scored separately: Travel, Activities, Physical activities, Feelings, Relationships, Sexual function and Nighttime bladder control. We also calculated a single index score. The U-UDI contains 9 items summarized in a single score that measures the extent to which incontinence symptoms bother patients and an urge symptoms summary score. Patients completed the questions at: start of baseline week, end of baseline week, week 4 and week 12 (final dose). RESULTS: The questions were completed by the 257 patients enrolled in the study (91% female, mean age = 60 years). All item responses showed good variability. Internal-consistency reliability was very good (Cronbach's alpha = 0.82-0.96). Test-retest reliability was good for all scales ([ICC] = 0.68-0.83). Discriminant validity was noted for all scales for patients with and without frequent incontinence (p < or = 0.006 all scales). All scales demonstrated responsiveness to change over time (Guyatt's statistic = magnitude of -1.04 - magnitude of -1.71). CONCLUSIONS: Psychometric testing indicated that the scales measured distinct and relevant domains of HRQOL for patients with urge incontinence, and that these two instruments are reliable, valid, and responsive to change in this condition.

Emerging pharmacologic approaches for the treatment of lower urinary tract disorders.

Lower urinary tract disorders include disorders affecting continence (stress urinary incontinence, urge urinary incontinence, and benign prostatic hyperplasia) and male erectile dysfunction. Although none of these conditions are fatal, they affect overall quality of life. Throughout modern medicine the treatment of these conditions was limited to psychological counseling or surgical intervention. In recent years, research defining the physiological mechanisms of continence and male sexual function has aided in the pharmacologic design of approaches to these conditions. These agents can act both centrally or on the peripheral genitourinary smooth muscle to alleviate disease symptoms. Incontinence is primarily treated with agents that act directly on the bladder smooth muscle such as muscarinic antagonists. However, afferent blockade to attenuate the spinalbulbospinal reflex pathway including mixed norepinephrine/serotonin reuptake inhibitors may provide a key breakthrough. Erectile dysfunction treatment has been revolutionized via the discovery of the nitric oxide pathway and phosphodiesterase 5 inhibitors. New peripheral targets as well as centrally acting agents represent potential emerging therapies. In this review, the pharmacologic basis of treatment of these disorders is discussed with special emphasis on emerging new therapeutics.

Management of overactive bladder and urge urinary incontinence in the elderly patient.

The symptoms of overactive bladder (OAB) and urge urinary incontinence may occur at any age but are particularly common among the elderly. These symptoms are associated with significant morbidity and often have a profound impact on patient quality of life. Urinary incontinence is an important contributor to the complications and economic cost of OAB for both community-dwelling and institutionalized elderly individuals. Many patients with OAB do not seek treatment because of embarrassment, fear of surgery, or the misperceptions that the problem is untreatable or is a normal and inevitable consequence of aging. Nonpharmacologic therapies improve bladder control by modifying lifestyle and behavior to prevent urine loss. This requires patient and caregiver motivation and can be time consuming. Improved results may be obtained by combining these strategies with pharmacotherapy or by means of pharmacotherapy alone. The most commonly used pharmacologic agents are the muscarinic receptor antagonists. These include oxybutynin, tolterodine, and three agents that have recently been approved for use in the United States: trospium, darifenacin, and solifenacin. In general, these therapies are well tolerated and safe; however, the selection of an optimal agent merits careful consideration. For elderly patients, important considerations include tolerability, absence of drug interactions, and the availability of a range of dosages to tailor treatment to individual patients. Primary care practitioners and geriatricians can have a key role in successful diagnosis and treatment of OAB. It is important for these physicians to realize that satisfactory outcomes may be achieved within the scope of a busy outpatient practice.

Rehabilitation vs drug therapy for urge urinary incontinence: short-term outcome.

The objective of this study was to compare the short-term effectiveness of rehabilitation treatment with a standard drug treatment for urge urinary incontinence (UUI). The study design includes parallel clinical trial in an outpatient urogynecologic clinic setting. The subjects were 44 women who suffered from UUI and who were systematically assigned to a rehabilitation group (REH) (N=24) or a medication group (MED) (N=20). The intervention for REH was consisted of five visits during a 3-month period of pelvic floor muscle training and behavioral training, whereas for MED was extended release oxybutynin at 5 mg/day, for 3 months. The urinary symptoms considered were frequency of voiding per day and night (freq/day and freq/night), number of incontinent episodes per week based on a bladder diary, and data based on the Incontinence Quality of Life Instrument (I-QoL). In the within-group comparison, both groups had improved significantly over time with respect to urinary symptoms and I-QoL (p<0.01). In addition, there was a significant group-time interaction effect on freq/day. While REH improved during the 3-month follow-up period, the MED group deteriorated to mean baseline value (p<0.01). A significant negative association was found between the urinary symptoms and the I-QoL at the end of follow-up (r (p)=-0.35 to -0.62, p<0.05). Three months after the intervention, both groups maintained the achievements of the intervention period. In addition, the REH group demonstrated additional improvement in mean freq/day while the condition of MED patients deteriorated to baseline values.
