Bladder neck support prosthesis: a nonoperative treatment for stress or mixed urinary incontinence

PURPOSE: We evaluated the usefulness and safety of a bladder neck support prosthesis in patients with stress or mixed incontinence. MATERIALS AND METHODS: A total of 57 women with stress and 20 with mixed incontinence completed a 12-week prospective clinical trial of a bladder neck support prosthesis. While indexes of incontinence episodes, leakage amounts and urgency along with a bothersome index were subjectively evaluated, a 60-minute pad test and urinary flow parameters were objectively evaluated. Three patients scheduled to undergo surgery for stress incontinence voluntarily used the device, and provided urodynamic data and cystourethrograms. Two prongs at 1 end of the ring, a type of elastic vaginal pessary, elevate the bladder neck against the pubic bone and facilitate pressure transmission around the bladder neck, resulting in urinary continence. RESULTS: Four subjective indexes significantly improved. There was no urinary flow obstruction. Urine loss decreased from 20.6 to 4.8 gm. per hour (p < 0.001) on the 60-minute pad test. Of the patients 22 (29%) reported complete continence and 39 (51%) had decreased severity of incontinence by more than 50%. Minor adverse effects occurred in 26% of the patients. Taking subjective evaluation, changes in objective parameters and adverse effects into consideration, 62 patients (81%) had some or maximum benefit according to the global usefulness rating. CONCLUSIONS: The bladder neck support prosthesis is safe, well tolerated and clinically effective for the treatment of stress or mixed incontinence.     

Fecal incontinence in women

Pelvic floor disorders are common in women. Most gynecologists are well versed in the management of urinary incontinence and uterovaginal prolapse; however, knowledge of disorders involving the anorectum is often lacking. This review will discuss the issue of anorectal incontinence in women, attempt to provide a logical outline for evaluation and treatment, and offer potential methods of prevention.     

Bladder outlet obstruction in women

While voiding dysfunction is relatively common in women, true bladder outlet obstruction is a rare condition and may be present in a misleading manner. To make an accurate diagnosis and tailor appropriate treatment, urodynamic investigation is required. However, even sophisticated urodynamic studies have limitations in predicting obstruction as a complication of anti-incontinence surgery and response to ureterolysis.     

Urinary incontinence and bacteriuria in women

We analyzed the urodynamic data and their relationship with significant bacteriuria in 103 consecutive female patients (mean age = 55.7 yrs) with urinary incontinence. Significant bacteriuria was observed in 25.2% of the cases. E. coli was the pathogen most frequently isolated (70.3%). Significant bacteriuria was demonstrated in 29.3% of the patients with urge-incontinence. The most frequent type of incontinence in patients with bacteriuria was no urodynamic reproduction of urinary incontinence (42.8%). Bladder instability was not associated with significant bacteriuria (27.2%). Significant bacteriuria was observed in 75% of the patients with lower urinary tract obstruction, 66.6% of the patients who voided by abdominal straining and 26.3% of those with postvoiding residual urine. These findings indicate that urine culture should be done in patients with no urodynamic reproduction of urinary incontinence. There was no statistically significant correlation between urge-incontinence/bladder instability and significant bacteriuria. Consequently, antibiotics should not be used routinely in female urinary incontinence.     

Treatment of stress urinary incontinence in women

Involuntary urinary leakage due to a rise in abdominal pressure caused by stress (cough, laugh, change in position, walking, running or carrying heavy weight) is a clinical entity often experienced by women. Management can be based on physical therapy techniques, drugs or surgery but indications and results to be expected are still very largely debated. Cure of an underlying condition such as obesity, or chronic bronchitis may be sufficient in some cases and others may benefit from "preventive" physical therapy to reinforce the perineum after difficult pregnancy and delivery. Alpha-stimulating drugs have also been proposed to increase sphincter tone. Surgery gives the best results. Several procedures have been proposed, usually based on classical retropubic colposuspension and aponevrosis loops. Success rate is approximately 80 to 90% although the lack of a sufficient understanding of the underlying mechanism involved, makes it impossible to predict outcome. Results in women with recurrent incontinence are less satisfactory.     

Urinary incontinence in women in a geriatric ward

101 elderly female patients participated in a multidisciplinary programme for the diagnosis and management of urinary incontinence. Their median age was 81 years. 83 patients had been incontinent for more than 12 months. In only 23 patients was incontinence recognised as a problem prior to admission, and 69 patients claimed that they had never received any treatment for their disability. Urge and mixed incontinence were found to be the most prevalent forms, based on symptoms and simple measurements. After assessment, one to six measures were implemented for each patient in order to counteract internal and external causes of incontinence. The patients were reviewed after 6-8 weeks. 60 patients claimed there was an improvement, including 20 who described themselves as "much improved", and seven who had become continent. It is suggested that a hospital stay may provide a suitable opportunity to undertake primary assessment and treatment of incontinence in elderly women.     

Quality of life following bladder training in older women with urinary incontinence

The elaboration of new mortality tables by the Swiss statistical office has allowed to estimate the impact of different pathology or risk factors on the average life duration of the resident population in Switzerland. Thus, attributable death of the smoking habits have for effect to decrease the life expectancy of swiss citizens of 2.9 years for men and 0.7 years for women, for the period 1988/1993. The calculation of mortality rates attributable to this factor of risk shows nevertheless that the risk of death has decreased since the end of years 1960 for all quinquennial age groups between 35 and 74 years. The smoking habits would be responsible of approximately 16% of deaths observed in the swiss population and 20% of premature deaths (between 25 and 64 years). The present analysis shows furthermore that different evolutions of the mortality associated with the smoking habits characterize men and women.     

New approaches for managing stress incontinence in women

Stress urinary incontinence is a problem for one in four women seen in the primary care setting. The incontinence usually is not identified as women do not view it as a problem, do not seek treatment, and turn to self-care practices. Technology in product development is evolving that can assist women in managing their incontinence. This article reviews new innovations in treatment that can be recommended by primary care providers.     

Exercise testing in coronary artery disease with ST-segment abnormalities at rest

Two feeding bioassays were conducted to study the mortality pattern, incidence of edema and ascites formation and plasma composition of turkey poults fed diets containing varying levels of toxic fat (fat contaminated with polychlorinated dibenzo-p-dioxins) and/or salt. No significant changes in plasma concentrations of electrolyte and total protein and packed cell volume were observed in slaughtered poults fed diets containing toxic fat compared with poults fed a normal diet. However, a positive dose-response relationship between levels of dietary toxic fat (0,2 and 5%) and incidence of mortality with edema, ascites and hydropericardium was observed in poults fed diets containing 1% salt. The toxic effects of polychlorinated dibenzo-p-dioxins were accentuated by increasing the level of salt (0.5, 1 and 3%) in the diet. Mortality started at nine days of age and increased on days 10 and 11. The present experiments demonstrated that gross pathological changes similar to those reported for "chick edema disease" caused by feeding polychlorinated dibenzo-p-dioxins, could also be produced in young turkey poults. The etiology of the toxic effects of these organic compounds in edema formation is discussed.     

Cough-induced leak-point pressure--a valid measure for assessing treatment in women with stress incontinence

BACKGROUND: Presently available urodynamic methods are of little use for assessing the severity of urinary stress incontinence or for evaluating of treatment, Cough-induced leak-point pressure may prove to be a more useful urodynamic method in these respects. A vaginal anti-incontinence device was used to validate this new urodynamic method. AIM: The primary aim was to determine the extent to which cough-induced leak-point pressure was affected by the vaginal device. Secondary aims were to study the short-term effects of the vaginal device on leakage and urinary flow, and to relate the change in cough-induced leak-point pressure to the change in leakage as expressed by a short-term pad test. METHODS: In a prospective study of 22 women with a history of stress incontinence, the effect of a new vaginal anti-incontinence device (Conveen Continence Guard) on cough-induced leak-point pressure, a short-term pad test and urinary flow was studied. RESULTS: Cough-induced leak-point pressure increased from 99.9 to 138.9 cm H2O, while leakage, measured by a short-term pad test, decreased from 22.7 to 3.3 g when using the device. Urinary flow was not significantly reduced by the device. CONCLUSIONS: Cough-induced leak-point pressure is a valid, quantitative, dynamic measure of urethral closure function which can be used to study the effects of treatment in patients with stress incontinence. The vaginal device is effective for treatment of stress incontinence in the short-term, without reducing urinary flow.     

Pelvic floor rehabilitation in women affected with stress urinary incontinence. Authors' experience

BACKGROUND: This study evaluated pelvic floor rehabilitation as a possible treatment for urinary stress incontinence: a challenge to tradition. METHODS: In this study 20 female subjects with urinary stress incontinence had rehabilitation therapy, at first in the outpatients clinic with motivated physiotherapists and afterwards by home exercises. RESULTS: At the end of 3 months of training, stress incontinence had disappeared in 7 patients (35%), while an improvement was recorded in 13 (65%). CONCLUSIONS: In summary, pelvic floor rehabilitation program can be an effective alternative to surgical approach in reducing the frequency of urinary leakage. Further studies are needed to identify factors predicting success and to improve the techniques of pelvic floor rehabilitation.     

Urinary stress incontinence in women and its conservative therapy

Urinary incontinence is the most frequent symptom of impaired function of the lower urinary pathways. The most frequent cause of the development of stress incontinence is damage of the muscular pelvic floor and associated damage of the continent mechanism. In addition to surgical procedures there exist also various types of conservative treatment. The author submit different types of this treatment and the protocol used in his department.
