Étude comparative de la morphologie du plancher pelvien des femmes âgées continentes et avec incontinence urinaire

But: Cette étude a pour but de comparer : a)la morphologie du plancher pelvien (PP), du col vésical et du sphincter urogénital strié (SUS) par IRM et b) la fonction du PP par palpation digitale (PERFECT scheme) chez les femmes âgées continentes ou avec incontinence urinaire à l’effort (IUE) et mixte (IUM). Méthode: Les femmes ont appris à contracter correctement leur PP et la fonction de leur PP a été évaluée. Une séance d’IRM dynamique 3T a suivi. Résultats: 66 femmes ont participé à l’étude. Les groupes étaient similaires en âge, IMC, nombre d’accouchements vaginaux et d’hystérectomie. La validité et la fidélité des différentes mesures anatomiques utilisées ont été confirmées au début de cette étude. Afin de contrôler l’effet potentiel de la taille du bassin sur les autres paramètres, les femmes ont été appariées par la longueur de leur inlet pelvien. Les femmes avec IUM ont un PP plus bas et un support des organes pelviens plus faible, selon leurs ligne M, angle LPC/Ligne H et hauteur de la jonction urétro-vésicale (UV). Les femmes avec IUE ont un PP similaire à celui des continentes, mais présentent plus d’ouverture du col vésical et un angle UV postérieur plus large au repos que les autres groupes. Il n’y a aucune différence de morphologie du SUS entre les groupes. De plus, selon les résultats du PERFECT scheme, les femmes avec IU ont une force du PP plus faible que les continentes. Les femmes avec IUM montrent aussi une faible élévation des muscles du PP à la contraction. Les femmes avec IUE ont, quant à elle, un problème de coordination à la toux. Conclusion: Les déficits causant l’IUE et l’IUM sont différents, mais supportent tous le rationnel des exercices du PP pour le traitement de l’IUE et l’IUM. Ces résultats supportent le besoin de traitements de rééducation spécifiques aux déficits de chacun des types d’IU.

Costs of managing urinary and faecal incontinence in a sub-acute care facility: A "bottom-up" approach

Aims: To measure accurately the direct costs of managing urinary and faecal incontinence in the sub-acute care setting. Materials and Methods: Prospective observational study was undertaken in two sub-acute care units in a metropolitan hospital. A consecutive series of 29 consecutive patients with urinary and/or faecal incontinence, who were in-patients in a geriatric rehabilitation or subacute neurologic unit underwent routine timed voiding protocol, as per usual care. Face-to-face bedside recordings of all incontinence care, with detailed cost analysis, were undertaken. Results: A total of 3,621 occasions of continence care were costed. The median time per 24 hr spent caring for incontinence per patient was 109 min (interquartile range 88-140). Isolated urinary incontinence episodes occurred in 28 patients (96.5%), mixed urinary/faecal incontinence episodes observed in 79.3%, and episodes of pure faecal incontinence were seen in 62%. The median costs of incontinence care in the sub-acute setting was $49AU per 24 hr, the major share ($41) spent on staff wages. The incontinence tasks of toileting assistance, pad changes, bed changes and catheter care were spread evenly across the three 8 hr shifts of duty. Conclusions: As our population demographics include an increasingly greater portion of the elderly, for whom long term institutional care is becoming relatively more scarce, provision of care in the sub-acute unit that may allow rehabilitation and return to home warrants scrutiny. This is the first study that delineates the costs of managing urinary and faecal incontinence in the sub-acute care setting. Such costs are substantial and place a heavy burden upon night-time carets. (C) 2004 Wiley-Liss, Inc.

Leaking urine: Prevalence and associated factors in Australian women

The Women's Health Australia project provided the opportunity to examine the prevalence of leaking urine and associated variables in three large cohorts of Australian women 18-23 years of age (young N = 14,761), 45-50 (mid-age N = 14,070), and 70-75 (older N = 12,893). The proportion of women reporting leaking urine was 12.8% (95% CI: 12.2-13.3), 36.1% (35.2-37.0), and 35% (34.1-35.9) in each of the three cohorts, respectively. Logistic regression analysis showed significant associations between leaking urine and parity in the young and mid-age women, and between leaking urine and constipation, other bowel symptoms, body mass index, and urine that burns or stings in all three groups. in the mid-age and older cohorts, women who reported having both hysterectomy and prolapse repair, or prolapse repair alone, were also more likely to report leaking urine. Lower scores on the physical and mental component summary scores of the medical outcomes survey short form (36 items) questionnaire suggest lower quality of life among women who report leaking urine, compared with those who do not.

The development and evaluation of an incontinence screening questionnaire for female primary care

Although there is a high prevalence of leaking urine among Australian women, there are currently no standardized procedures for screening patients for incontinence in the primary care setting (known in Australia as general practice). In response to this, an incontinence screening questionnaire (ISQ) was developed and evaluated for use in general practice. Eighty-nine women completed an original compilation of 33 items that asked about situations associated with leaking urine, avoidance of leakage, and concern about leakage. Each item was assessed according to its acceptability for the population of female general practice patients, discriminative value, and test-retest reliability. These patients also underwent an objective test of incontinence, the 48-hour pad test, so that the screening items could be validated against an objective classification of incontinence. The study included women who had bladder control problems and those who did not. Eight items on the ISQ were shown to be acceptable to patients, discriminative, reliable, and valid indicators of objective incontinence. Five items were capable of predicting almost 70% of patients who showed objective leakage of urine and misclassified fewer than 15% of these patients. Those five items were selected for inclusion in the (refined) ISQ. (C) 2000 Wiley-Liss, Inc.

Model for Differential Nursing Diagnosis of Alterations in Urinary Elimination Based on Fuzzy Logic

Nursing diagnoses associated with alterations of urinary elimination require different interventions, Nurses, who are not specialists, require support to diagnose and manage patients with disturbances of urine elimination. The aim of this study was to present a model based on fuzzy logic for differential diagnosis of alterations in urinary elimination, considering nursing diagnosis approved by the North American Nursing Diagnosis Association, 2001-2002. Fuzzy relations and the maximum-minimum composition approach were used to develop the system. The model performance was evaluated with 195 cases from the database of a previous study, resulting in 79.0% of total concordance and 19.5% of partial concordance, when compared with the panel of experts. Total discordance was observed in only three cases (1.5%). The agreement between model and experts was excellent (kappa = 0.98, P < .0001) or substantial (kappa = 0.69, P < .0001) when considering the overestimative accordance (accordance was considered when at least one diagnosis was equal) and the underestimative discordance (discordance was considered when at least one diagnosis was different), respectively. The model herein presented showed good performance and a simple theoretical structure, therefore demanding few computational resources.

Incontinência Urinária

O AA, após definir a U.I como um sintoma, um sinal e uma condição ilustra com estudos epidemiológicos que estamos perante um problema médico, social e económico maior. Por outro lado a fisioterapia da U.I. é explicada no contexto do equilíbrio entre as forças expulsivas e retencionistas na fase de enchimento. Deste modo explica a U.I por urgência devido a bexiga hiperactiva e a U.I. ao stress por hipermobilidade do colo da bexiga e ou lesão do esfíncter intrínseco. O diagnóstico e a severidade destes diferentes tipos de U.I. é apresentado tendo como base: a história clínica; o pad teste ; o registo diário demicções; o Q tip test. Os exames complementares como: O Rx simples do aparelho urinário; a urinocultura; os estudos urodinâmicos; a eco transvaginal avaliam os factores de continência alterados. O tratamento da U.I. é exposto tendo como base a fisiopatologia, e exemplificando de uma forma sistemática com casos clínicos.

Chirurgie de l'incontinence urinaire a l'effort féminine par voie transobturatrice: dehors-dedans ou dedans-dehors? Etude anatomique comparative

OBJECTIVE: Transobturator route is now largely used for the positioning of the supporting sub uretral tape in the surgical treatment of female urinary incontinence. This operation can be done using the original technique from the outside to the inside or by inside to outside. Our anatomic study evaluates the specific dangers of each MATERIAL AND METHODS: Our study is based on the dissection of seven fresh bodies, therefore 14 obturator regions. The dissections were done after the positioning of the tape from outside to inside on one side and inside to outside on the other side. We particularly studied the distances separating the tape from the inferior pudendal vascular bundle and the posterior branch of the obturator nerve. RESULTS: With the inside - outside technique there is a greater proximity between the path of the tape and the studied structures, therefore the risk of damage is greater. CONCLUSIONS: The two techniques are not equivalent. There are less vascular and neurological risk using the original outside to inside technique.

Experimental evaluation of an electromechanical artificial urinary sphincter in an animal model.

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The AMS 800 urinary control system is the gold standard for the treatment of urinary incontinence due to sphincter insufficiency. Despite excellent functional outcome and latest technological improvements, the revision rate remains significant. To overcome the shortcomings of the current device, we developed a modern electromechanical artificial urinary sphincter. The results demonstrated that this new sphincter is effective and well tolerated up to 3 months. This preliminary study represents a first step in the clinical application of novel technologies and an alternative compression mechanism to the urethra. OBJECTIVES: To evaluate the effectiveness in continence achievement of a new electromechanical artificial urinary sphincter (emAUS) in an animal model. To assess urethral response and animal general response to short-term and mid-term activation of the emAUS. MATERIALS AND METHODS: The principle of the emAUS is electromechanical induction of alternating compression of successive segments of the urethra by a series of cuffs activated by artificial muscles. Between February 2009 and May 2010 the emAUS was implanted in 17 sheep divided into three groups. The first phase aimed to measure bladder leak point pressure during the activation of the device. The second and third phases aimed to assess tissue response to the presence of the device after 2-9 weeks and after 3 months respectively. Histopathological and immunohistochemistry evaluation of the urethra was performed. RESULTS: Bladder leak point pressure was measured at levels between 1091 ± 30.6 cmH2 O and 1244.1 ± 99 cmH2 O (mean ± standard deviation) depending on the number of cuffs used. At gross examination, the explanted urethra showed no sign of infection, atrophy or stricture. On microscopic examination no significant difference in structure was found between urethral structure surrounded by a cuff and control urethra. In the peripheral tissues, the implanted material elicited a chronic foreign body reaction. Apart from one case, specimens did not show significant presence of lymphocytes, polymorphonuclear leucocytes, necrosis or cell degeneration. Immunohistochemistry confirmed the absence of macrophages in the samples. CONCLUSIONS: This animal study shows that the emAUS can provide continence. This new electronic controlled sequential alternating compression mechanism can avoid damage to urethral vascularity, at least up to 3 months after implantation. After this positive proof of concept, long-term studies are needed before clinical application could be considered.

Prise en charge actuelle de l'incontinence anale [Current management of anal incontinence]

Even though anal incontinence affects a significant proportion of the population, causing a major burden to both patient and society, it still remains "the last closet issue". Less than a third of patients will share this problem with their physician. Consequently, the incidence of anal incontinence is difficult to determine, varying from 2-50%. Since this disabling condition is often associated with urinary incontinence and/or pelvic organ prolapse, a multidisciplinary team approach is required. A wide range of therapeutic options are available. When dietary, medical and rehabilitative treatments have failed, sacral neuromodulation should be considered in selected cases. More invasive surgery is usually undertaken in the presence of major structural defects. The aim of this article is to suggest a comprehensive way of identifying and treating anal incontinence.

American Cancer Society guideline for the early detection of prostate cancer: update 2010.

In 2009, the American Cancer Society (ACS) Prostate Cancer Advisory Committee began the process of a complete update of recommendations for early prostate cancer detection. A series of systematic evidence reviews was conducted focusing on evidence related to the early detection of prostate cancer, test performance, harms of therapy for localized prostate cancer, and shared and informed decision making in prostate cancer screening. The results of the systematic reviews were evaluated by the ACS Prostate Cancer Advisory Committee, and deliberations about the evidence occurred at committee meetings and during conference calls. On the basis of the evidence and a consensus process, the Prostate Cancer Advisory Committee developed the guideline, and a writing committee drafted a guideline document that was circulated to the entire committee for review and revision. The document was then circulated to peer reviewers for feedback, and finally to the ACS Mission Outcomes Committee and the ACS Board of Directors for approval. The ACS recommends that asymptomatic men who have at least a 10-year life expectancy have an opportunity to make an informed decision with their health care provider about screening for prostate cancer after they receive information about the uncertainties, risks, and potential benefits associated with prostate cancer screening. Prostate cancer screening should not occur without an informed decision-making process. Men at average risk should receive this information beginning at age 50 years. Men in higher risk groups should receive this information before age 50 years. Men should either receive this information directly from their health care providers or be referred to reliable and culturally appropriate sources. Patient decision aids are helpful in preparing men to make a decision whether to be tested.

Predictive factors for voiding dysfunction after transobturator slings

PURPOSE: To identify the predictive factors for voiding dysfunction after transobturator slings. METHODS: We retrospectively reviewed the records of all patients who underwent a transobturator sling between March 2003 and December 2008. A total of 514 women had available data with at least a six-week follow-up. Patients' demographics, preoperative symptoms, urodynamic testing including multichannel voiding studies and surgical variables were tabulated. Voiding dysfunction was defined by a catheterized or ultrasonographic postvoid residual greater than 100 cc (≥six weeks after the procedure) associated with any complaints of abnormal voiding. Univariate logistic regression analysis was performed with respect to postoperative voiding dysfunction. RESULTS: The patient population had a mean age of 58.5±12.9 years. Thirty-three out of 514 patients (6.4%) had postoperative voiding dysfunction according to our definition, and 4 (0.78%) required sling transection. No differences were observed between normal and dysfunctional voiders in age, associated prolapse surgery, preoperative postvoid residual, preoperative urinary flow rate, prior pelvic surgery, and menopausal status. Valsalva efforts during the preoperative pressure flow study was the only predictive factor for postoperative voiding dysfunction, 72.4% dysfunctional versus 27.6% normal (p<0.001). CONCLUSION: Preoperative Valsalva maneuver during the micturition could identify those at risk for voiding dysfunction after transobturator sling, and it should be noted during preoperative counseling.

Inflammation, oxidative stress, glomerular filtration rate, and albuminuria in elderly men : a cross-sectional study

BACKGROUND: The role of inflammation and oxidative stress in mild renal impairment in the elderly is not well studied. Accordingly, we aimed at investigating the associations between estimated glomerular filtration rate (eGFR), albumin/creatinine ratio (ACR), and markers of different inflammatory pathways and oxidative stress in a community based cohort of elderly men. FINDINGS: Cystatin C-based GFR, ACR, and biomarkers of cytokine-mediated inflammation (interleukin-6, high-sensitivity C-reactive protein[CRP], serum amyloid A[SAA]), cyclooxygenase-mediated inflammation (urinary prostaglandin F2alpha [PGF2alpha]), and oxidative stress (urinary F2 isoprostanes) were assessed in the Uppsala Longitudinal Study of Adult Men(n = 647, mean age 77 years). RESULTS: In linear regression models adjusting for age, BMI, smoking, blood pressure, LDL-cholesterol, HDL-cholesterol, triglycerides, and treatment with statins, ACE-inhibitors, ASA, and anti-inflammatory agents, eGFR was inversely associated with CRP, interleukin-6, and SAA (beta-coefficient -0.13 to -0.19, p < 0.001 for all), and positively associated with urinary F2-isoprostanes (beta-coefficient 0.09, p = 0.02). In line with this, ACR was positively associated with CRP, interleukin-6, and SAA (beta- coefficient 0.09-0.12, p < 0.02 for all), and negatively associated with urinary F2-isoprostanes (beta-coefficient -0.12, p = 0.002). The associations were similar but with lower regression coefficients in a sub-sample with normal eGFR (>60 ml/min/1.73 m2, n = 514), with the exception that F2-isoprostane and SAA were no longer associated with eGFR. CONCLUSION: Our data indicate that cytokine-mediated inflammation is involved in the early stages of impaired kidney function in the elderly, but that cyclooxygenase-mediated inflammation does not play a role at this stage. The unexpected association between higher eGFR/lower albuminuria and increased F2-isoprostanes in urine merits further studies.

Clinical and quality-of-life outcomes after autologous fascial sling and tension-free vaginal tape: a prospective randomized trial

Purpose: Evaluate the impact autologous fascial sling (AFS) and tension-free vaginal tape (TVT) procedures on quality-of-life in incontinent women. Materials and Methods: Forty-one women were randomly distributed into two groups. Group G1 (n = 21), underwent AFS and group G2 (n = 20) TVT implant. The clinical follow up was performed at 1, 6, 12 and 36 months. Results: TVT operative time was significantly shorter than AFS. Cure rates were 71% at 1 month, 57% at 6 and 12 months in G1. In G2, cure rates were 75% at 1 month, 70% at 6 months and 65% at 12 months; there was no significant difference between groups. As regards the satisfaction rate, there was no statistical difference between groups. Analysis of quality of life at 36 months revealed that there was no significant difference between groups. Conclusion: Similar results between AFS and TVT, except for operative time were shorter in TVT.
