Adherence to a behavioral program to prevent incontinence.

This exploratory study assesses factors predicting adherence to a behavioral intervention to prevent urinary incontinence. Community-dwelling, post-menopausal women (N = 164) were taught pelvic floor muscle training (PFMT) and bladder training (BT) and followed with surveys for 1 year. Content analysis of open-ended responses coded descriptions of approaches participants used to incorporate PFMT into daily life. Exploratory bivariate and logistic regression analyses determined predictors of approach used and adherence. Results indicate women incorporated PFMT into their lives using either a routine or ad hoc approach. Those using a routine approach at 3 months were 12 times more likely to adhere (odds ratio [OR] = 12.4, confidence interval [CI] = 4.0-38.8, p < .001) at a high level at 3 months and significantly more likely to maintain that level 12 months post-intervention (OR = 2.7, CI = 1.2-6.0, p < .014). Practicing BT was related to high adherence.

Prevalence of urinary incontinence in community dwelling men: a cross sectional nationwide epidemiological survey.

PURPOSE: Epidemiological studies on urinary incontinence (UI) in adult men of all ages are scarce. We aim to describe the UI phenomenon among community dwelling adult males in the United States (US). MATERIALS AND METHODS: We analyzed data from male respondents to a 14-item mailed UI symptoms questionnaire to the National Family Opinion (NFO) World Group Panel of 45,000 households matching the US 2000 census population on five key demographic elements. RESULTS: A total of 29,903 households responded, of which 21,590 were male heads of household (mean age 50 +/-15.2 years old). A total of 2,059 men (12.7%) reported symptoms of UI during the last 30 days. Symptoms of urge urinary incontinence (UUI), stress urinary incontinence (SUI), mixed urinary incontinence (MUI) symptoms, and other types of urinary incontinence (OUI) symptoms, were reported by 44.6%, 24.5%, 18.8%, and 12.3%, respectively. Among those with UI symptoms, the proportion of UUI and MUI symptoms increases with age while SUI symptoms decrease as age increases. Of those with UI symptoms, 44% consulted a physician of whom 57% did so within 6 months of the onset of symptoms. Treatments reported included absorbent pads (48%), prescription medication (30%), surgical procedure (18%), and intermittent catheterization (4%). CONCLUSIONS: Almost 1 in 10 males reported symptoms of UI. The UI prevalence rate increases with age and UUI symptoms is the most prevalent type reported. Less than half of men with UI symptoms sought professional help and half of them did so within 6 months of onset of UI symptoms.

Perceptions and behaviours of women with bladder control problems.

OBJECTIVES: To evaluate women's perceptions about bladder control problems. METHODS: 757 Women with one or more bladder control symptoms (frequency, urgency, stress or urge urinary incontinence and nocturia) participated in an Internet-based survey. A separate study involved 12 focus groups including a total of 180 women with bladder control problems. RESULTS: Respondents in the survey reported multiple symptoms, e.g. stress urinary incontinence (72%), frequency (56%), nocturia (45%), urge urinary incontinence (43%) and urgency (33%). Women in both the survey and the focus groups revealed extensive use of coping mechanisms to manage their symptoms. The focus groups revealed that many women were not aware that overactive bladder (OAB) is a pathophysiological condition. Approximately 30% of respondents in the survey felt uncomfortable talking to their doctor about their condition. Among women who did speak with their doctor, stress-related symptoms were described more readily than urge-related symptoms. In the survey, only about half (56%) of the women felt their OAB medication was effective, and half (50%) stopped taking their medication at some point. Information from the focus groups suggested that some women may have unrealistic expectations of onset of efficacy or extent of benefit and may be unprepared for managing side effects. CONCLUSIONS: Feelings of embarrassment and limited understanding of the pathophysiology of OAB can contribute to miscommunication between a woman and her doctor. Patient education regarding reasonable expectations coupled with suggestions for coping with unwanted side effects will likely result in better management.

Evaluation of a mass mailing recruitment strategy to obtain a community sample of women for a clinical trial of an incontinence prevention intervention.

OBJECTIVES: Questions exist about using mass mailings to recruit representative samples to participate in clinical trials. The MESA Prevention Study (Medical, Epidemiologic and Social Aspects of Aging), a randomized controlled clinical trial to prevent urinary incontinence (UI), utilized a mass mailing recruitment procedure to recruit a representative sample of women to participate in a behavioral modification program. This paper seeks to expand the literature of mass mailing recruitment strategies for prevention studies by describing the procedures used to recruit healthy, continent, post-menopausal women aged 55-80 years. METHODS: Sociodemographic data collected from recruited subjects is compared with on-line national census data to evaluate the representativeness of the sample recruited from a purchased mailing list. RESULTS: The mass mailing procedure resulted in 3.3% positive response. Of those that returned a positive response, 37.6% were deemed eligible at first screening. Comparisons of study demographic data with state and county census data indicate that the sample obtained was representative of the communities. CONCLUSIONS: The mass mailing strategy was an effective means of recruiting a representative sample of women, aged 55-80. Short falls and recommendations for successful community sample recruitment strategies for clinical trials in older adult women are elaborated upon.

Comparison of the long-term outcomes between incontinent men and women treated with artificial urinary sphincter.

PURPOSE: We compared the long-term outcome of AUS between men and women who received the device for the management of stress urinary incontinence. MATERIALS AND METHODS: Between August 1983 and January 2004, 126 consecutive patients received the AUS AMS 800 at our center placed by the senior author (ACD). Of these patients 108 (53 men, 55 women) and 168 devices (88 in men, 80 in women) were available for review. Outcome measures include complications, duration and etiology of AUS failure, and satisfactory continence. RESULTS: Mean followup was 8.1 +/- 5.6 years. Of the 108 patients 18 (40%) men and 31 (56%) women had no complications (p = 0.09). Of the 168 devices 76 (45%) eventually failed (44 or 50% in men, 32 or 40% in women, p = 0.19). The incidences of failed device classified as mechanical, nonmechanical or iatrogenic were not significantly different (p = 0.07). Median device durations were 6.9 and 11.2 years in men and women, respectively (p = 0.002). Satisfactory continence was achieved in 82% of patients, in 43 (81%) men and in 46 (84%) women (p = 0.73), including 5 (9%) men and 35 (64%) women who were dry (0 pads, p = 0.01), 28 (53%) men and 4 (7%) women who wear 1 pad (p = 0.01), and 10 (19%) men and 7 (13%) women who use 2 pads per day. CONCLUSIONS: There were no differences in overall satisfactory continence and device failure rates. However, women have a higher dry rate (0 pad use) and longer functioning device duration compared to their male counterparts.

Learning outcomes of a group behavioral modification program to prevent urinary incontinence.

This study describes acquisition of knowledge and motor skill in bladder training (BT) and pelvic floor muscle training (PFMT) and adherence following a behavioral modification program (BMP). Essentially continent (0-5 episodes in past year) community-dwelling older women (n = 359) were randomized to treatment (n = 164), a 2-h group education session supplemented by one brief individualized session of approximately 10 min, or control (n = 195), no instruction, and followed for 12 months. Knowledge, motor skill, and adherence to the BMP were documented. Changes in pelvic muscle function and voiding interval were used to validate self-reported adherence. Following group instruction, mean BT and PFMT knowledge was 90 and 86%, respectively; 68% demonstrated correct PFMT technique without additional instruction, 29% required brief instruction, and 3% were unable to learn PFMT technique. Adherence ranged from 63 to 82% for PFMT and 58 to 67% for BT. Group instruction supplemented with brief individual instruction as needed is an effective teaching method for BT and PFMT.

A new vaginal speculum for pelvic organ prolapse quantification (POPQ).

The purposes of this study were to introduce a new vaginal speculum, describe the technique of using the new speculum in identifying and measuring the severity of pelvic organ prolapse (POP), and present results of a pilot study comparing the new speculum to the conventional instruments used in performing POP quantification (POPQ). The new speculum has retractable upper and lower blades marked in centimeters. POPQ was performed with one instrument using the new speculum and multiple instruments performing the conventional technique. Twenty-two patients underwent POPQ-11 using the new speculum and 11 using conventional instruments. The duration of the procedure and the level of discomfort were assessed. The POPQ method using the new speculum is described. Preliminary experience with the new speculum showed that the length of examination is significantly shorter (p<0.001) and the comfort level is better than with the conventional technique (p=0.088). A new vaginal speculum with adjustable blades simplifies POPQ. Preliminary testing suggests potential savings in procedure time and reduction in patient discomfort.

Intravesical resiniferatoxin for the treatment of interstitial cystitis: a randomized, double-blind, placebo controlled trial.

PURPOSE: Interstitial cystitis is a painful bladder condition of unknown etiology and poorly understood pathophysiology. Current therapies have met with limited success. Vanilloid receptor agonists such as resiniferatoxin (RTX) desensitize C-fibers that transmit pain; it is hypothesized that such drugs will be effective in the treatment of interstitial cystitis and painful bladder syndrome by decreasing the pain that leads to urinary frequency and urgency. MATERIALS AND METHODS: A randomized, double-blind, placebo controlled study was conducted in 163 patients with interstitial cystitis. Participants were randomly assigned to receive a single intravesical dose of 50 ml of either RTX 0.01 microM, 0.05 microM, 0.10 microM, or placebo. Safety and efficacy was evaluated over 12 weeks. The primary efficacy endpoint was the Global Response Assessment, a 7-point scale rating overall change in symptoms of interstitial cystitis after 4 weeks. Secondary efficacy endpoints included reduction in pain, urgency, frequency, nocturia, average void volume, and the O'Leary-Sant Symptom and Problem Indexes. RESULTS: RTX did not improve overall symptoms, pain, urgency, frequency, nocturia, or average void volume during 12 weeks followup. RTX resulted in a dose-dependent increase in the incidence of instillation pain, but was otherwise generally well tolerated. CONCLUSIONS: In the largest prospective, randomized clinical trial reported to date with intravesical vanilloid therapy, single administration of RTX at doses of 0.01 microM to 0.10 microM was not effective in patients with interstitial cystitis.

Surgical management of urinary incontinence: a geriatric perspective.

Urinary incontinence (UI) is highly prevalent in the elderly population. There are several types that call for specific treatment. The three most common options in managing UI are behavioral modification programs, pharmacologic agents, and surgical intervention. In general, a nonsurgical approach is the preferred first choice, unless it already has been tried and failed or if the patient clearly wishes a more definitive surgical therapy.

The artificial urinary sphincter and urinary catheterization: what every physician should know and do to avoid serious complications.

The artificial urinary sphincter is an effective tool for urinary incontinence that is being seen in more patients because of the increased numbers of artificial sphincters being implanted and increased patient lifespan. If a patient with an artificial urinary sphincter is catheterized without manipulation of the artificial sphincter, serious irreversible complications may result. All of these complications are easily preventable by physician and nurse awareness of the artificial urinary sphincter and knowledge of how it works. Therefore, it is important for every physician to be knowledgeable about the artificial urinary sphincter.

Medical management of urinary incontinence.

Treatment options for urinary incontinence include behavioral techniques, pharmacologic agents, and surgical procedures. Caregivers use pharmacotherapy heavily because of its availability, immediacy of results, and convenience. However, only pharmacotherapy for urge incontinence has advanced to the level at which several drugs that have undergone rigorous scientific testing using randomized controlled trials have received FDA approval; these are the antimuscarinic and anticholinergic/direct smooth muscle relaxant drugs. However, promising new drugs targeting other receptors are under investigation. There is no FDA-approved drug for stress incontinence or overflow incontinence. Pharmacologic clinical trials for urinary incontinence are no different than pharmacologic trials in other areas. A randomized controlled trial is the best approach for documenting effectiveness and safety. A rigorous trial should include identification of primary and secondary outcomes. The measurement tools of outcomes must be reliable and validated. Preferably, the severity level of urinary incontinence should be established, and measurement of effectiveness must include durability. Not only must side effects be identified, but their impact on the quality of life must be quantified. An exciting area in pharmacologic treatment of urinary incontinence is the method of drug delivery. In addition to sustained release oral medication, the transdermal patch and the intravaginal route are starting to be used in clinical practice. The intravesical route is still in the investigational phase. Pharmacologic research for urinary incontinence is now entering an exciting time because technologic advances are creating new agents with more precise targeting and more sophisticated methods of delivery are being developed and tested.

Prevention of urinary incontinence by behavioral modification program: a randomized, controlled trial among older women in the community.

PURPOSE: We determined whether a behavioral modification program (BMP) taught to groups of continent older women would decrease the incidence of urinary incontinence, increase pelvic muscle strength and improve voiding control. MATERIALS AND METHODS: We performed a randomized, controlled trial comparing a BMP treatment group to a control, no treatment group in ambulatory, postmenopausal, continent women (0 to 5 days of incontinent episodes in the previous year) 55 years and older who were followed for 12 months. Qualified volunteers from 4 Michigan counties were randomly assigned to a control or a treatment group, consisting of a 2-hour classroom presentation on BMP followed 2 to 4 weeks later with individualized evaluation to test knowledge, adherence and skills in behavioral techniques, and brief reinforcement of the technique as needed. Followup was done by telephone and mail every 3 months except month 12, when all participants underwent final clinical evaluation. Outcome measures were continence status, pelvic floor muscle strength and voiding frequency/intervoid interval. RESULTS: A total of 195 control and 164 treated participants completed the study. Baseline data on the 2 groups were not statistically different. At 12 months the treatment group was statistically significantly better than the control group in continence status (p = 0.01), pelvic muscle strength (pressure score p = 0.0003 and displacement score p <0.0001), improved voiding frequency (p <0.0001) and intervoid interval (p <0.0001). CONCLUSIONS: To our knowledge we report the first randomized, controlled trial of BMP for preventing urinary incontinence in older women. It demonstrated feasibility and efficacy in improving continence status, pelvic muscle strength and voiding control as long as a year after treatment.

A referral center's experience with transitional cell carcinoma misdiagnosed as interstitial cystitis.

PURPOSE: There has been a recent trend to diagnose interstitial cystitis (IC) in a noninvasive way using a potassium sensitivity test, and a pelvic pain, urgency and frequency questionnaire. The concern is that significant pathology causing the bladder symptoms may be missed, such as transitional cell carcinoma. We present our experience with patients "labeled" as having IC who truly had cancer as the cause of irritative symptoms. MATERIALS AND METHODS: A retrospective review of patient records at our IC center was performed from 1998 to 2002. A total of 600 patients were seen at that time with the diagnosis of interstitial cystitis. RESULTS: Six patients (1%) previously diagnosed as having IC were found to have transitional cell carcinoma as the cause of symptoms, 4 of whom (67%) had no hematuria. Mean time from the diagnosis of IC to diagnosis of transitional cell carcinoma was 29.8 months. Irritative bladder symptoms resolved after identifying and treating the malignancy. CONCLUSIONS: Patients with irritative voiding symptoms require a thorough evaluation which may include cystoscopy, cytology and upper tract imaging. Hematuria was not a good predictor of cancer in our series. In the era before widespread use of minimally invasive means to diagnose IC (ie potassium sensitivity test, pelvic pain, urgency and frequency questionnaire) 1% of patients who were considered to have IC actually had transitional cell cancer as the cause of symptoms. One would expect that this number would increase if the criteria to diagnose IC and initiate treatment were oversimplified. Interstitial cystitis remains a diagnosis of exclusion.

Medical and self-care practices reported by women with urinary incontinence.

OBJECTIVES: To determine the extent to which women with incontinence have been identified by physicians, the coping and treatment strategies that incontinent women use, and the factors associated with treatment strategy utilization. STUDY DESIGN: A 2-stage, nationwide, cross-sectional survey. METHODS: Survey participants were adult women from representative US households in NFO WorldGroup survey panels. Of 2310 incontinent women who received the second-stage detailed questionnaire, 1970 (85%) responded. Descriptive analyses were performed to determine the impact of incontinence, the proportion of respondents who had talked to a physician about incontinence, the responses of physicians to these incontinent women, and coping strategies used. We conducted logistic regressions to determine factors associated with treatment strategy utilization. RESULTS: Almost half of incontinent women considered their incontinence moderately to extremely bothersome, yet only 56% of the moderately to extremely bothered women had ever talked to a physician about incontinence. In 85% of all cases, the incontinent woman, rather than the physician, raised the issue of incontinence. Coping strategies women reported ever trying included limiting fluid intake (38%) and physical activity (21%). Kegel exercises and prescription medications were used currently by 20% and 6% of this population, respectively. CONCLUSIONS: Among women of all ages, only about half of women bothered by incontinence have ever talked to a physician about it, and many incontinent women rely on strategies to avoid or conceal incontinence. A better understanding of the current use of coping and treatment strategies as well as the interaction between women and physicians regarding incontinence may help to inform efforts to optimize management of incontinence for women bothered by incontinence symptoms.

Sacral neuromodulation in patients with interstitial cystitis: a multicenter clinical trial.

Female patients with interstitial cystitis (IC) unresponsive to standard oral and intravesical therapy were enrolled at three clinical sites for percutaneous sacral nerve root stimulation (PNS) in a prospective, observational pilot study. Evaluation was in the form of a 3-day voiding diary completed both prior to and following the commencement of sacral nerve root stimulation. Symptoms were also assessed by the O'Leary-Sant Interstitial Cystitis Symptom and Problem Indices (ICSI and ICPI). Baseline and test stimulation values for voiding diary parameters and O'Leary-Sant scores were compared to determine treatment efficacy. A total of 33 patients were enrolled. Statistically significant improvements were seen in frequency, pain, average voided volume and maximum voided volume. Significant improvements were also seen in ICSI and ICPI scores. Subacute PNS appears to be effective in reducing symptom severity and increasing voided volumes in patients with IC previously unresponsive to standard therapy.
