EAU guidelines on surgical treatment of urinary incontinence

CONTEXT The European Association of Urology (EAU) guidelines on urinary incontinence published in March 2012 have been rewritten based on an independent systematic review carried out by the EAU guidelines panel using a sustainable methodology. OBJECTIVE We present a short version here of the full guidelines on the surgical treatment of patients with urinary incontinence, with the aim of dissemination to a wider audience. EVIDENCE ACQUISITION Evidence appraisal included a pragmatic review of existing systematic reviews and independent new literature searches based on Population, Intervention, Comparator, Outcome (PICO) questions. The appraisal of papers was carried out by an international panel of experts, who also collaborated in a series of consensus discussions, to develop concise structured evidence summaries and action-based recommendations using a modified Oxford system. EVIDENCE SUMMARY The full version of the guidance is available online (www.uroweb.org/guidelines/online-guidelines/). The guidance includes algorithms that refer the reader back to the supporting evidence and have greater accessibility in daily clinical practice. Two original meta-analyses were carried out specifically for these guidelines and are included in this report. CONCLUSIONS These new guidelines present an up-to-date summary of the available evidence, together with clear clinical algorithms and action-based recommendations based on the best available evidence. Where high-level evidence is lacking, they present a consensus of expert panel opinion.

Pelvic floor muscle activation and strength components influencing female urinary continence and stress incontinence: A systematic review

AIMS A better understanding of pelvic floor muscle (PFM) activation and strength components is a prerequisite to get better insight in PFM contraction mechanisms and develop more specific PFM-training regimens for female stress urinary incontinence (SUI) patients. The aim of this systematic review (2012:CRD42012002547) was to evaluate and summarize existing studies investigating PFM activation and strength components influencing female continence and SUI. METHODS PubMed, EMBASE, and Cochrane databases were systematically searched for literature from January 1980 to November 2013 for cross-sectional studies comparing female SUI patients with healthy controls and intervention studies with SUI patients reporting on the association between PFM activation and strength components and urine loss. Trial characteristics, evaluated PFM components, their definitions, measurement methods, study outcomes, as well as quality measures, based on the Cochrane risk of bias tool, were independently extracted. The high heterogeneity of the retrieved data made pooling of results impossible and therefore restricted the analysis to a systematic review. RESULTS Cross-sectional studies showed group differences in favor of the continent women compared to SUI patients for PFM activation or PFM maximal strength, mean strength or sustained contraction. All intervention studies showed an improvement of PFM strength and decrease in urine loss in SUI patients after physical therapy. CONCLUSIONS Higher PFM activation and strength components influence female continence positively. This systematic review underscored the need for a standardized PFM components' terminology (similar to rehabilitation and training science), standardized test procedures and well matched diagnostic instruments.

Patients with faecal peritonitis admitted to European intensive care units: an epidemiological survey of the GenOSept cohort.

INTRODUCTION Faecal peritonitis (FP) is a common cause of sepsis and admission to the intensive care unit (ICU). The Genetics of Sepsis and Septic Shock in Europe (GenOSept) project is investigating the influence of genetic variation on the host response and outcomes in a large cohort of patients with sepsis admitted to ICUs across Europe. Here we report an epidemiological survey of the subset of patients with FP. OBJECTIVES To define the clinical characteristics, outcomes and risk factors for mortality in patients with FP admitted to ICUs across Europe. METHODS Data was extracted from electronic case report forms. Phenotypic data was recorded using a detailed, quality-assured clinical database. The primary outcome measure was 6-month mortality. Patients were followed for 6 months. Kaplan-Meier analysis was used to determine mortality rates. Cox proportional hazards regression analysis was employed to identify independent risk factors for mortality. RESULTS Data for 977 FP patients admitted to 102 centres across 16 countries between 29 September 2005 and 5 January 2011 was extracted. The median age was 69.2 years (IQR 58.3-77.1), with a male preponderance (54.3%). The most common causes of FP were perforated diverticular disease (32.1%) and surgical anastomotic breakdown (31.1%). The ICU mortality rate at 28 days was 19.1%, increasing to 31.6% at 6 months. The cause of FP, pre-existing co-morbidities and time from estimated onset of symptoms to surgery did not impact on survival. The strongest independent risk factors associated with an increased rate of death at 6 months included age, higher APACHE II score, acute renal and cardiovascular dysfunction within 1 week of admission to ICU, hypothermia, lower haematocrit and bradycardia on day 1 of ICU stay. CONCLUSIONS In this large cohort of patients admitted to European ICUs with FP the 6 month mortality was 31.6%. The most consistent predictors of mortality across all time points were increased age, development of acute renal dysfunction during the first week of admission, lower haematocrit and hypothermia on day 1 of ICU admission.

Association between trends in clinical variables and outcome in intensive care patients with faecal peritonitis: analysis of the GenOSept cohort.

INTRODUCTION Patients admitted to intensive care following surgery for faecal peritonitis present particular challenges in terms of clinical management and risk assessment. Collaborating surgical and intensive care teams need shared perspectives on prognosis. We aimed to determine the relationship between dynamic assessment of trends in selected variables and outcomes. METHODS We analysed trends in physiological and laboratory variables during the first week of intensive care unit (ICU) stay in 977 patients at 102 centres across 16 European countries. The primary outcome was 6-month mortality. Secondary endpoints were ICU, hospital and 28-day mortality. For each trend, Cox proportional hazards (PH) regression analyses, adjusted for age and sex, were performed for each endpoint. RESULTS Trends over the first 7 days of the ICU stay independently associated with 6-month mortality were worsening thrombocytopaenia (mortality: hazard ratio (HR) = 1.02; 95% confidence interval (CI), 1.01 to 1.03; P <0.001) and renal function (total daily urine output: HR =1.02; 95% CI, 1.01 to 1.03; P <0.001; Sequential Organ Failure Assessment (SOFA) renal subscore: HR = 0.87; 95% CI, 0.75 to 0.99; P = 0.047), maximum bilirubin level (HR = 0.99; 95% CI, 0.99 to 0.99; P = 0.02) and Glasgow Coma Scale (GCS) SOFA subscore (HR = 0.81; 95% CI, 0.68 to 0.98; P = 0.028). Changes in renal function (total daily urine output and renal component of the SOFA score), GCS component of the SOFA score, total SOFA score and worsening thrombocytopaenia were also independently associated with secondary outcomes (ICU, hospital and 28-day mortality). We detected the same pattern when we analysed trends on days 2, 3 and 5. Dynamic trends in all other measured laboratory and physiological variables, and in radiological findings, changes inrespiratory support, renal replacement therapy and inotrope and/or vasopressor requirements failed to be retained as independently associated with outcome in multivariate analysis. CONCLUSIONS Only deterioration in renal function, thrombocytopaenia and SOFA score over the first 2, 3, 5 and 7 days of the ICU stay were consistently associated with mortality at all endpoints. These findings may help to inform clinical decision making in patients with this common cause of critical illness.

Orthotopic Ileal Bladder Substitution in Women: Factors Influencing Urinary Incontinence and Hypercontinence.

BACKGROUND Urinary incontinence or the inability to void spontaneously after ileal orthotopic bladder substitution is a frequent finding in female patients. OBJECTIVE To evaluate how hysterectomy and nerve sparing affect functional outcomes and whether these relate to pre- and postoperative urethral pressure profile (UPP) results. DESIGN, SETTING, AND PARTICIPANTS Prospectively performed pre- and postoperative UPPs of 73 female patients who had undergone cystectomy and bladder substitution were correlated with postoperative voiding and continence status. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Outcome analyses were performed with the Kruskal-Wallis test, Wilcoxon-Mann-Whitney, or two-group post hoc testing with the Bonferroni correction. Chi-square or Fisher exact tests were applied for the categorical data. RESULTS AND LIMITATIONS Of postoperatively continent or hypercontinent patients, 22 of 43 (51.2%) had the uterus preserved; of incontinent patients, only 4 of 30 (13.3%, p<0.01) had the uterus preserved. Of postoperatively continent or hypercontinent patients, 27 of 43 patients (62.8%) had bilateral and 15 of 43 (34.9%) had unilateral attempted nerve sparing. In incontinent patients, 11 of 30 (36.7%) had bilateral and 16 of 30 (53.3%) had unilateral attempted nerve sparing (p=0.02). When compared with postoperatively incontinent patients, postoperatively continent patients had a longer functional urethral length (median: 32mm vs 24mm; p<0.001), a higher postoperative urethral closing pressure at rest (56cm H2O vs 35cm H2O; p<0.001) as well as a higher preoperative urethral closing pressure at rest (74cm H2O vs 47.5cm H2O; p=0.01). The main limitation was the limited number of patients. CONCLUSIONS In female patients undergoing radical cystectomy and bladder substitution, preservation of the uterus and attempted nerve sparing results in better functional outcomes. The preoperative UPPs correlate with postoperative voiding and continence status and may predict which patients are at a higher risk of functional failure after bladder substitution. PATIENT SUMMARY If preservation of the urethra's innervation is not possible during cystectomy, poor functional results with bladder substitutes are likely.

Standardized pelvic floor exercises improve stress urinary incontinence in women with intrinsic sphincter deficiency.

OBJECTIVES Pelvic floor rehabilitation is the conservative therapy of choice for women with stress urinary incontinence (SUI). The success rate of surgical procedures in SUI patients with intrinsic sphincter deficiency (ISD) is low. The aim of this study was to analyse the effect of a standardized physiotherapy on patients with SUI and normotonic urethra and ISD. METHODS In this study, 64 patients with ISD and 69 patients with normotonic urethra were enrolled. Maximum urethral pressure (MUCP) >20 cm H2 O was considered as normotonic urethral pressure. Before and after physiotherapy MUCP was measured and cough testing was performed. Additionally, patient reported outcome was assessed using the King's Health Questionnaire (KHQ). For statistical analyses Excel 2010 (Microsoft Inc; Redmond, Washington) and SPSS 20 (SPSS Inc; Chicago, Illinois) for Windows were used. Power calculation was based on the primary endpoint incontinence impact and general health. For power calculation, GraphPad Statmate version 2.00 for Windows was used. RESULTS Sixty-four patients with ISD and 69 patients with normotonic urethra were included in the study. In SUI patients with normotonic and hypotonic urethra KHQ-scores regarding the primary endpoins "general health" and "incontinence impact" significantly improved following standardized physiotherapy. In both groups MUCP increased after physiotherapy. In SUI patients with ISD standardized physiotherapy resulted in a decreased incidence of a positive cough test. CONCLUSIONS Standardized physiotherapy should be offered to patients with SUI and ISD. Long-term results are subject to future studies. Neurourol. Urodynam. © 2015 Wiley Periodicals, Inc.

Can urethrolysis resolve outlet obstruction related symptoms after Burch colposuspension for stress urinary incontinence?

OBJECTIVE Bladder outlet obstruction may occur after any incontinence surgery and may present as OAB, hesitancy and or the feeling of incomplete emptying. Aim of this study was to analyze the clinical and urodynamical outcome after urethrolysis in patients presenting with various clinical symptoms after Burch colposuspension for stress urinary incontinence. STUDY DESIGN Between January 2005 and December 2014, all patients who presented with symptoms and with bladder outlet obstruction were included. All patients had undergone Burch or Cowan colposuspension for stress urinary incontinence previously. Primary endpoint was the visual analogue scale (VAS) as measurement of patient perceived disease impact. Secondary endpoints were the various domains of the King's Health Questionnaire, urodynamic parameters as detrusor pressure at maximum flow, residual urine and sonographic bladder wall thickness before and six months after intervention. RESULTS Seventy-two female patients were included in this study whereof 42 suffered from urgency and urge incontinence, 20 from hesitancy and/or slow stream, seven from residual urine of more than 100ml and three from a combination of urgency and residual urine. VAS improved significantly (p<0.0001). Quality of life as determined by the King's Health Questionnaire improved for the domains general health, role limitations, emotions, physical limitations, personal limitations and incontinence impact significantly. Micturition pressure dropped significantly from 43cmH2O (95% CI 19-59cmH2O) to 18cmH2O (95% CI 16-23.5 H2O). Residual urine changed from 110ml (range 20-380ml) to 32ml (20-115ml). Bladder wall thickness decreased from 7mm (95% CI 6.235-7.152) to 5mm (95% CI 5.037-5.607; p<0.01). CONCLUSION Urethrolysis may resolve patients' symptoms and lower micturition pressure but irritative symptoms may persist.

Involuntary reflexive pelvic floor muscle training in addition to standard training versus standard training alone for women with stress urinary incontinence: study protocol for a randomized controlled trial

BACKGROUND Pelvic floor muscle training is effective and recommended as first-line therapy for female patients with stress urinary incontinence. However, standard pelvic floor physiotherapy concentrates on voluntary contractions even though the situations provoking stress urinary incontinence (for example, sneezing, coughing, running) require involuntary fast reflexive pelvic floor muscle contractions. Training procedures for involuntary reflexive muscle contractions are widely implemented in rehabilitation and sports but not yet in pelvic floor rehabilitation. Therefore, the research group developed a training protocol including standard physiotherapy and in addition focused on involuntary reflexive pelvic floor muscle contractions. METHODS/DESIGN The aim of the planned study is to compare this newly developed physiotherapy program (experimental group) and the standard physiotherapy program (control group) regarding their effect on stress urinary incontinence. The working hypothesis is that the experimental group focusing on involuntary reflexive muscle contractions will have a higher improvement of continence measured by the International Consultation on Incontinence Modular Questionnaire Urinary Incontinence (short form), and - regarding secondary and tertiary outcomes - higher pelvic floor muscle activity during stress urinary incontinence provoking activities, better pad-test results, higher quality of life scores (International Consultation on Incontinence Modular Questionnaire) and higher intravaginal muscle strength (digitally tested) from before to after the intervention phase. This study is designed as a prospective, triple-blinded (participant, investigator, outcome assessor), randomized controlled trial with two physiotherapy intervention groups with a 6-month follow-up including 48 stress urinary incontinent women per group. For both groups the intervention will last 16 weeks and will include 9 personal physiotherapy consultations and 78 short home training sessions (weeks 1-5 3x/week, 3x/day; weeks 6-16 3x/week, 1x/day). Thereafter both groups will continue with home training sessions (3x/week, 1x/day) until the 6-month follow-up. To compare the primary outcome, International Consultation on Incontinence Modular Questionnaire (short form) between and within the two groups at ten time points (before intervention, physiotherapy sessions 2-9, after intervention) ANOVA models for longitudinal data will be applied. DISCUSSION This study closes a gap, as involuntary reflexive pelvic floor muscle training has not yet been included in stress urinary incontinence physiotherapy, and if shown successful could be implemented in clinical practice immediately. TRIAL REGISTRATION NCT02318251 ; 4 December 2014 First patient randomized: 11 March 2015.

Training primary care physicians to offer their patients faecal occult blood testing and colonoscopy for colorectal cancer screening on an equal basis: a pilot intervention with before-after and parallel group surveys.

OBJECTIVES Primary care physicians (PCPs) should prescribe faecal immunochemical testing (FIT) or colonoscopy for colorectal cancer screening based on their patient's values and preferences. However, there are wide variations between PCPs in the screening method prescribed. The objective was to assess the impact of an educational intervention on PCPs' intent to offer FIT or colonoscopy on an equal basis. DESIGN Survey before and after training seminars, with a parallel comparison through a mailed survey to PCPs not attending the training seminars. SETTING All PCPs in the canton of Vaud, Switzerland. PARTICIPANTS Of 592 eligible PCPs, 133 (22%) attended a seminar and 106 (80%) filled both surveys. 109 (24%) PCPs who did not attend the seminars returned the mailed survey. INTERVENTION A 2 h-long interactive seminar targeting PCP knowledge, skills and attitudes regarding offering a choice of colorectal cancer (CRC) screening options. OUTCOME MEASURES The primary outcome was PCP intention of having their patients screened with FIT and colonoscopy in equal proportions (between 40% and 60% each). Secondary outcomes were the perceived role of PCPs in screening decisions (from paternalistic to informed decision-making) and correct answer to a clinical vignette. RESULTS Before the seminars, 8% of PCPs reported that they had equal proportions of their patients screened for CRC by FIT and colonoscopy; after the seminar, 33% foresaw having their patients screened in equal proportions (p<0.001). Among those not attending, there was no change (13% vs 14%, p=0.8). Of those attending, there was no change in their perceived role in screening decisions, while the proportion responding correctly to a clinical vignette increased (88-99%, p<0.001). CONCLUSIONS An interactive training seminar increased the proportion of physicians with the intention to prescribe FIT and colonoscopy in equal proportions.

Egg production, hatching, faecal pellet production of Calanus finmarchicus in the North Atlantic

The samples were collected using a T-80 net (375 µm mesh size) equipped with a non-filtering cod-end in the North Atlantic during the G.O. Sars Trans-Atlantic cruise in 2013. Within 15-30 minutes after the recovery, 20 Calanus finmarchicus females were sorted out under microscope in ice chilled petri dishes and incubated individually in 600 ml polycarbonate culture bottles resulting in 20 replicate measurements. The bottles were filled with 50 µm screened seawater originated from 6 m water depth. The samples were incubated upright in thermoroom for 24 hours at the surface temperature (3°C). After the samples had been filtered (40 µm filter), female prosome length, egg as well as pellet abundance were determined. Subsequently, eggs from six females were incubated in petri dishes at 5°C. After 4 days, the number of nauplii and eggs were counted in order to calculate hatching success.

Faecal pellet production of copepoda collected in water depth up to 30 meters in the eastern Mediterranean Sea in Oktober 2008 during SES_GR2

Mesozooplankton is collected by vertical tows within the Black sea water body mass layer in the NE Aegean, using a WP-2 200 µm net equipped with a large non-filtering cod-end (10 l). Macrozooplankton organisms are removed using a 2000 µm net. A few unsorted animals (approximately 100) are placed inside several glass beaker of 250 ml filled with GF/F or 0.2 µm Nucleopore filtered seawater and with a 100 µm net placed 1 cm above the beaker bottom. Beakers are then placed in an incubator at natural light and maintaining the in situ temperature. After 1 hour pellets are separated from animals and placed in separated flasks and preserved with formalin. Pellets are counted and measured using an inverted microscope. Animals are scanned and counted using an image analysis system. Carbon- Specific faecal pellet production is calculated from a) faecal pellet production, b) individual carbon: Animals are scanned and their body area is measured using an image analysis system. Body volume is then calculated as an ellipsoid using the major and minor axis of an ellipse of same area as the body. Individual carbon is calculated from a carbon- total body volume of organisms (relationship obtained for the Mediterranean Sea by Alcaraz et al. (2003) divided by the total number of individuals scanned and c) faecal pellet carbon: Faecal pellet length and width is measured using an inverted microscope. Faecal pellet volume is calculated from length and width assuming cylindrical shape. Conversion of faecal pellet volume to carbon is done using values obtained in the Mediterranean from: a) faecal pellet density 1,29 g cm**3 (or pg µm**3) from Komar et al. (1981); b) faecal pellet DW/WW=0,23 from Elder and Fowler (1977) and c) faecal pellet C%DW=25,5 Marty et al. (1994).
