Electrochemically activated solution as bladder irrigation-An individual curative trial in patients with neurogenic lower urinary tract dysfunction and recurrent urinary infections.

AIMS: Driven by increasing awareness of antibiotic stewardship, especially in the vulnerable group of patients with neurogenic lower urinary tract dysfunction (NLUTD), whose frequent need for invasive interventions leads to a high incidence of recurrent urinary tract infections (rUTIs), the goal was to find an alternative to antibiotic treatment. Our intention was for the treatment to be locally administered and well-tolerated as well as to avoid the risk of antimicrobial resistance. METHODS: A retrospective analysis of 12 catheterized NLUTD patients was performed within the setting of an individual curative trial. The decision to implement the investigational intervention was made on an individual basis with the aim of eliminating lower urinary tract bacteria before diagnostic procedures or to treat rUTI. Electrochemically activated solution (ECAS) was used as bladder irrigation (BI). The following assessments were undertaken: microbiological analysis of urine, analysis of leukocytes/erythrocytes (per µl urine); microbial resistance and sensitivity to antibiotics before and after therapy; clinical signs and patients' state of health. RESULTS: Eradication of bacteria or an increase in microbial sensitivity to antibiotics was observed in 50%-70% of patients. No adverse events were seen. Due to the restrictions of an individual curative trial, the results are limited by the small number of patients and the absence of a control group. CONCLUSION: In NLUTD patients with rUTIs, the use of ECAS BI to eliminate bacteriuria before invasive procedures (e.g., urodynamics, preoperative procedures) or to treat rUTI was shown to be a promising alternative to antibiotic treatment.

Incontinence in frail elderly persons: Report of the 6th International Consultation on Incontinence.

BACKGROUND: Evidence-based guidelines for the management of frail older persons with urinary incontinence are rare. Those produced by the International Consultation on Incontinence represent an authoritative set of recommendations spanning all aspects of management. AIMS: To summarize the available evidence relating to the management of urinary incontinence in frail older people published since the 5th International Consultation on Incontinence. MATERIALS AND METHODS: A series of systematic reviews and evidence updates were performed by members of the working group to update the 2012 recommendations. RESULTS: Along with the revision of the treatment algorithm and accompanying text, there have been significant advances in several areas of the management of lower urinary tract symptoms in frail older people. DISCUSSION: The committee continues to note the relative paucity of data concerning frail older persons and draw attention to knowledge gaps and research opportunities. Clinicians treating older people with lower urinary tract symptoms should use the available evidence from studies of older people combined with careful extrapolation of those data from younger subjects. Due consideration to an individual's frailty and wishes is crucial.

[Current aspects of neurogenic dysfunctions of the lower urinary tract in multiple sclerosis]. / Aktuelles zu neurogenen Dysfunktionen des unteren Harntraktes bei Multipler Sklerose.

BACKGROUND: In the clinical management of patients with multiple sclerosis (MS), the challenge is to make an early diagnosis and initiate adequate treatment of neurogenic disorders of the lower urinary tract (NLUTD). Various national guidelines provide practical recommendations which are sometimes discordant. OBJECTIVE: To develop a simple evidence-based algorithm for detecting NLUTD in patients with MS that could be taken as a principle for deriving therapeutic consequences. MATERIAL AND METHODS: A prospective multicenter study was initiated as a direct result of two multidisciplinary conferences. The aim was to identify statistically and clinically relevant parameters for the routine diagnosis of NLUTD in patients with MS. Urodynamic abnormalities served as the gold standard. At three subsequent consensus conferences, the results of the study were discussed, a diagnostic algorithm was developed and consensus was reached on a first-line treatment. RESULTS AND DISCUSSION: The proposed algorithm enables the detection of NLUTD in patients with MS with the help of four statistically significant predictors: 1) the residual urine volume, 2) the number of urinary tract infections (UTI) within the last 6 months, 3) the standardized micturition frequency and 4) the presence/absence of urinary incontinence. The newly developed algorithm has proved to be efficient with the following results: approximately 75% of the patients do not need a urodynamic examination for a first-line treatment decision. In 25% of cases, urodynamic examinations are essential for an adequate treatment decision. Routine assessments include the patient medical history, residual urine volume measurement, a micturition diary and a uroflowmetry (optional).

Prediction of survival outcomes following postoperative radiotherapy after radical prostatectomy for prostate cancer.

Background: To evaluate predictive factors for survival outcomes after post-prostatectomy radiotherapy.Material and methods: In the years 2003-2008, 324 patients have received postoperative radiotherapy a median time of 14 months after radical prostatectomy. All patients have been treated up to 66.0-66.6 Gy in 1.8-2.0 Gy fractions. Predictive factors were analyzed at two stages, using a multivariable Cox regression analysis: (1) based on factors known before radiotherapy and (2) based on prostate-specific antigen response after radiotherapy.Results: Median follow-up after radiotherapy was 121 months. Prostate-specific antigen before radiotherapy, pN1 and Gleason score remained predictive factors for disease-free (hazard ratio, HR of 6.0, 2.3 and 2.5) and overall survival (HR of 2.8, 2.0 and 1.6) in multivariable analysis. Prostate-specific antigen levels increased despite radiotherapy in 27% of patients in the first six months. Failed response following salvage radiotherapy and prostate-specific antigen doubling time at the time of biochemical recurrence were predictive factors for disease-free (HR of 2.8 and 7.3; p < .01) and overall survival (HR of 2.2 and 2.6; p < .01).Conclusion: To reach the best survival outcomes following prostatectomy, salvage radiotherapy should be initiated early with low prostate-specific antigen levels, especially in patients with higher Gleason scores. Patients not responding to radiotherapy and/or patients with a short prostate-specific antigen doubling time after radiotherapy are candidates for early additional treatments.

Urodynamic and clinical studies in patients with late-onset Pompe disease and lower urinary tract symptoms.

AIMS: In late-onset Pompe disease (LOPD), a lysosomal storage disorder with glycogen accumulation in several tissues, patients suffer from progressive skeletal muscle weakness. Lower urinary tract symptoms (LUTS) have rarely been reported. The aim of this study is to objectively assess LUTS in patients with LOPD for the first time using urodynamic studies and to determine differences between LOPD patients with and without LUTS. METHODS: Eighteen patients with LOPD were recruited, of whom seven patients (38.9%) reported LUTS (both voiding and storage symptoms). Six of these patients underwent urodynamic studies. Medical histories and motor function tests were compared between the 7 patients with LUTS and the 11 patients without LUTS. The Student t test was used to determine an association between the two cohorts. RESULTS: In the seven LOPD patients with LUTS urodynamics revealed neurogenic dysfunction, underactive detrusor, and bladder outlet obstruction. These patients had suffered from clinical symptoms for a longer period of time before starting enzyme replacement therapy (P = .017) than patients without LUTS. They also scored more poorly on muscle function tests. Urodynamic results point to neurogenic causes for LUTS in LOPD, that is, neurogenic reflex bladder or impaired filling sensation. This could be due to glycogen accumulation in the urothelium and central nervous system. Patients with LUTS also seem to be more severely affected by LOPD than patients without LUTS. CONCLUSION: LUTS in LOPD requires early and specific treatment to limit the development of severe health problems. Urodynamic studies should be considered in assessing LUTS.

Is polypropylene mesh material fundamentally safe for use as a reconstructive material in vaginal surgery: ICI-RS 2019?

Polypropylene (PP) mesh has been used as a primary or adjuvant material for vaginal reconstruction for both stress urinary incontinence (SUI) and pelvic organ prolapse (POP) for decades. Whether polypropylene is the optimal material for such indications has been called into question by clinicians, regulatory agencies and the public in several countries around the world. This paper is a report of presentations and subsequent discussion at the annual International Consultation on Incontinence Research Society (ICI-RS) Meeting in June 2019 in Bristol, UK on the proposal "Is polypropylene mesh material fundamentally safe for use as a reconstructive material in vaginal surgery?" in which several of the salient issues were presented and discussed.

Can multicentre urodynamic studies provide high quality evidence for the clinical effectiveness of urodynamics? ICI-RS 2019.

AIMS: Lower urinary tract (LUT) function can be investigated by urodynamic studies (UDS) to establish underlying functional abnormalities in the LUT. A multicentre registry could present an opportunity to improve the scientific evidence base for UDS. During the International Consultation on Incontinence Research Society (ICI-RS) meeting in Bristol, United Kingdom 2019, an expert panel discussed the potential of a multicentre urodynamic registry to improve the quality of urodynamic output. METHODS: the potential importance of a multicentre urodynamic registry, parameter inclusion, quality control, and pitfalls during a registry roll-out were reviewed and discussed. RESULTS AND CONCLUSIONS: The clinical utility, evaluation, and effectiveness of UDS remain poorly defined due to a lack of high quality evidence and large study populations. Therefore, the ICI-RS proposes formation of a urodynamic panel for future roll-out of a registry. The inclusion of basic parameters was discussed and the essential parameters were defined as well as the potential pitfalls of a registry roll-out. The discussion and recommendations in this paper form the base for future urodynamic registry development.

Should we routinely assess psychological morbidities in idiopathic lower urinary tract dysfunction: ICI-RS 2019?

AIMS: Psychological morbidities play a major role in idiopathic lower urinary tract dysfunction (iLUTD). The aim of the Think Tank (TT) was to discuss the relevance of psychological morbidities in idiopathic LUTD over the life span, including overactive bladder (OAB) or dysfunctional voiding (DV) and methods of assessment. METHODS: The paper is based on a selective review of the literature and in-depth discussions, leading to research recommendations regarding the assessment of psychological morbidities in iLUTD on children and adults held during the TT of the International Consultation on Incontinence Research Society in 2019. RESULTS: Psychological comorbidities affect the health behaviors and treatment outcomes in patients with iLUTD. Both clinically relevant comorbid mental disorders, as well as subclinical psychological symptoms have a major impact and negatively influence incontinence treatment. Research is needed to elucidate mechanisms underlying iLUTD and psychological comorbidities. Clinical studies are needed to determine how perception generation and cognition impacts on the relationship of urinary perceptions, symptoms, and objective urodynamic function. Due to high psychological comorbidity rates, screening with validated, generic questionnaires for emotional and behavioral disorders in children with nocturnal enuresis, daytime urinary incontinence, and fecal incontinence is recommended. Brief screening is recommended for all adults with iLUTD, especially with OAB and DV, who are refractory to treatment. CONCLUSIONS: Due to the high rate and relevance in clinical practice, screening for psychological comorbidities is recommended for all age groups. The research recommendations of this TT may be followed to improve the assessment of psychological morbidities in iLUTD.

Retropubic vs transobturator Argus adjustable male sling: Results from a multicenter study.

AIMS: To comparatively analyse outcomes after ARGUS classic and ArgusT adjustable male sling implantation in a real-world setting. METHODS: Inclusion criteria encompassed: non-neurogenic, moderate-to-severe stress urinary incontinence (≥2 pads), implantation of an ARGUS classic or ArgusT male sling between 2010 and 2012 in a high-volume center (>150 previous implantations). Functional outcomes were assessed using daily pad usage, 24-hour pad testing, and International Consultation on Incontinence (ICIQ-SF) questionnaires. Continence was defined as zero pads per 24 hours. Complications were graded using Clavien-Dindo scale. For multivariate analysis, binary logistic regression models were used (P < .05). RESULTS: A total of 106 patients (n = 74 [ARGUS classic], n = 32 [ArgusT]) from four centers were eligible. Median follow-up was 44.0 months (24-64). Patient cohorts were well-balanced. We observed a statistical trend in favor of ARGUS classic regarding postoperative urine loss based on standardized 24-hour pad test (71 ± 162 g [ARGUS classic] vs 160 ± 180 g [ArgusT]); P = .066]. Dry rates were 33.3% (ARGUS classic) and 11.8% (ArgusT, P = .114). In multivariable analysis, ArgusT male sling could not be confirmed as an independent predictor of decreased success (OR, 0.587; 95% CI; 0.166-2.076, P = .408). There were no Clavien IV and V complications. Inguinal pain was significantly higher after ArgusT implantation (P = .033). Explantation rates were higher for ArgusT compared to ARGUS classic (14.0 vs 23.3%; P = .371). Longer device survival for the ARGUS classic male sling was observed in Kaplan-Meier analysis (P = .198). CONCLUSIONS: In the largest comparative analysis of ARGUS classic and ArgusT male sling with the longest follow-up to date, we observed low continence rates with superior functional outcomes and decreased explantation rates after ARGUS classic implantation.

High/low-volume center experience predicts outcome of AMS 800 in male stress incontinence: Results of a large middle European multicenter case series.

AIM: To analyze the influence of implantation volume of artificial sphincters (AMS 800) on outcome in a large central European multicenter cohort study. METHODS: As part of the DOMINO (Debates on Male Incontinence) project, the surgical procedures and outcomes were retrospectively analyzed in a total of 473 patients who received an artificial sphincter (AMS 800) between 2010 and 2012. Clinics that implanted at least 10 AMS 800 per year were defined as high-volume centers. RESULTS: Sixteen centers had a mean rate of 9.54 AMS 800/y of which five clinics were identified as high-volume centers. They implanted significantly more double cuffs (55% vs 12.1%; P < .001), used the perineal approach significantly more often (78% vs 67.7%; P = .003) and chose larger mean cuff sizes (4.63 cm vs 4.42 cm; P = .002). With a mean follow-up of 18 months, the revision rate was significantly higher at low-volume centers (38.5% vs 26.7%; P = .037), urethral erosion being the main reason for revision. Social continence (0-1 pads/24 h) was achieved significantly more often in high-volume centers (45.5% vs 24.2%; P = .002). CONCLUSIONS: Our study showed significantly better continence results and lower revision rates at high-volume centers, confirming earlier results that are still true in this decade. We, therefore, recommend surgery for male incontinence at qualified centers.

Secondary Sling Implantation after Failure of Primary Surgical Treatment for Male Stress Urinary Incontinence: A Retrospective Study.

OBJECTIVE: The artificial urinary sphincter (AUS) is the surgical gold standard after previously failed surgical treatment for male urinary stress incontinence. The evidence for a male sling as salvage treatment is poor, but there is a proportion of patients that refuse implantation of an AUS or have a relative contraindication. The goal of our retrospective study was an analysis of outcome and complications of patients with a secondary sling after previously failed surgery for stress urinary incontinence (SUI). MATERIALS AND METHODS: Data on 186 patients who had a prior incontinence surgery were extracted from the DOMINO database. 139 patients (74.7%) received an AUS and 41 patients (22.0%) who had received a secondary sling system between 2010 and 2012 after previously failed surgery for male urinary incontinence could be identified and were further analyzed. RESULTS: Eight patients (19.5%) received a secondary repositioning sling and 33 patients (80.5%) received a secondary adjustable sling system. A prior surgery for urethral stricture was performed in 4 patients (9.8%). No major intraoperative complications were reported. A simultaneous explantation was performed in 12 patients (29.3%). The mean number of pad reductions was 4.93 (p = 0.026). No intraoperative complications and no postoperative surgical revisions were reported. The mean follow-up of the patient cohort with a secondary sling was 16 months. CONCLUSION: We provide the largest cohort of male patients up to date with a secondary sling after primary failure of surgery for male SUI. Although the procedure is a rarely performed surgery and without a high level of evidence, a secondary adjustable male sling system might be a feasible option in selected patients with acceptable complication rates, whereas a valuable outcome regarding continence rates cannot be sufficiently supplied by our data.

Patient Selection in Surgical Centers of Expertise in the Treatment of Patients with Moderate to Severe Male Urinary Stress Incontinence.

OBJECTIVE: To analyze decision-making in patients with male urinary incontinence (SUI) in centers of expertise. The artificial urinary sphincter (AUS) remains the gold standard for male patients with moderate to severe SUI but adjustable male slings are a minimally invasive treatment option with good results, hence without a high level of evidence regarding the optimal patient selection. MATERIALS AND METHODS: In total, 220 patients (88 AUS; 132 adjustable slings) were investigated from the DOMINO database that underwent surgery between 2010 and 2012 in 5 urological departments that offer adjustable sling systems as well as AUS systems for patients with moderate to severe urinary incontinence. For statistical analysis, the Mann-Whitney U test was used to identify differences between both groups. RESULTS: Patients selected for an adjustable male sling were less likely to have a neurological disease (5.3 vs. 9.1%; p = 0.030), a prior urethral stricture (22.7 vs. 50.0%; p = 0.001), a prior incontinence surgery (24.4 vs. 45.5%; p = 0.01), or a prior radiation therapy (26.5 vs. 40.1%; p = 0.001). The severity of preoperative incontinence was higher in patients selected for an AUS with a mean pad usage per day of 7.60 versus 5.80 (p < 0.001). Mean postoperative pad usage and patients' subjective perception were comparable in both groups. CONCLUSION: In centers offering both options, the decision-making is mainly based upon presence of radiation therapy and previous failed incontinence surgery. Despite the more complex patient cohort selected for an AUS implantation with a possible impact on the postoperative outcome, the functional results seem to be comparable indicating a proper preoperative patient assessment and selection in this cohort.

Elderly patients aged ≥ 75 years with locally advanced prostate cancer may benefit from local treatment: a population-based propensity score-adjusted analysis.

OBJECTIVE: To evaluate whether elderly patients aged ≥ 75 years with locally advanced prostate cancer (LAPC) may benefit from local treatment (LT). METHODS: Elderly patients aged ≥ 75 years with non-metastatic cT3-4 LAPC who were treated with LT [radical prostatectomy (RP), radiation therapy (RT)] or non-LT (NLT) were identified. After propensity score matching (PSM), cancer-specific mortality (CSM) and other-cause mortality (OCM) rates were assessed. In the assessment of LT vs. NLT and RP vs. RT, multivariable competing risk regression (MVA CRR) analysis was used. RESULTS: 368 and 482 paired patients were matched for LT vs. NLT and RP vs. RT, respectively. 5 and 10 years CSM rates were 9.4 vs. 18.5% in LT and 24.9 vs. 29.3% in NLT-treated patients, respectively (P < 0.0001). 5 and 10 years CSM rates were 3.4% vs. 8.6% in RP and 6.7% vs. 15.1% in RT-treated patients, respectively (P = 0.10). In the MVA CRR model, after PSM, NLT resulted in higher CSM rates in Gleason score 8-10 [subhazard ratio (sHR) = 2.83, P < 0.001], cT3b/4 (sHR = 3.97/2.56, P = 0.003/0.002), cN0 (sHR = 2.52, P < 0.001) or PSA > 10 ng/ml [sHR (PSA = 10.1-20 ng/ml) = 4.59, P = 0.03; sHR (PSA > 20 ng/ml) = 2.77, P = 0.001] patients compared with LT. However, no statistically significant difference in CSM was observed between RP and RT, except for cT3a patients in whom higher CSM rates were noted for RT compared with RP (sHR = 3.91, P = 0.02). CONCLUSION: LAPC patients may benefit from local treatment despite advanced age. However, this benefit was only seen in patients with cT3b/4, Gleason score 8-10, cN0 or PSA > 10 ng/ml.

Are there different patterns of detrusor overactivity which are clinically relevant? ICI-RS 2018.

INTRODUCTION: Different patterns of detrusor overactivity (DO) have been described and included in several standardization terminology documents. However, it is unclear if these different patterns have any clinical significance. METHODS: This is a report of the proceedings of Proposal 3: "Are there different patterns of detrusor overactivity which are clinically relevant?" from the annual International Consultation on Incontinence-Research Society (ICIRS) meeting, which took place from 14 to 16 June 2018, in Bristol, UK. RESULTS: We have collected and discussed, as a committee, the evidence about different urodynamic (UD) patterns of detrusor overactivity and their potential clinical significance. We reviewed the important previous basic research and clinical studies and compiled summaries. The discussion focused on clinical relevance of different UD patterns of DO and what further research is required. CONCLUSIONS: There are several UD definitions of patterns of detrusor overactivity, however the clinical relevance of these definitions remains unclear. Future research should concentrate on defining the pattern of DO in relation to clinical diagnosis, gender, age, and treatment outcomes.

How can we improve investigation, prevention and treatment for recurrent urinary tract infections - ICI-RS 2018.

BACKGROUND: Recurrent urinary tract infection (rUTI) is a chronic condition and has a significant impact on health-related quality of life. The commonly used definition for rUTI is greater than three episodes in a year or more than two in 6 months. Current diagnostic methods have been used worldwide for over five decades, despite well evidenced criticism. Enhanced culture techniques demonstrate that the microbiome of the bladder is far more complex than previously thought and begs a reappraisal of our current testing. Treatment of rUTI is based on a small number of antibiotic trials with some evidence showing a reduction in the number of positive cultures, but one must be cautious in interpreting the results and weigh against the risk of generation of antimicrobial resistance (AMR). AIM: The International Consultation on Incontinence-Research Society think tank reviewed the literature with a view to improving investigation, prevention and treatment of rUTI. METHODS: A multidisciplinary team of experts were invited to present evidence regarding the current diagnostic methods, recent advances related to bladder biome mapping and current treatment strategies, including antibiotic and nonantibiotic options. Current guidelines regarding antibiotic stewardship and concerns regarding AMR were discussed. DISCUSSION: Outcome of the think tank discussions are summarised with a set of recommendations to inform future research. Particular consideration is given to bacterial survival in the bladder after treatment as well as defects in urothelial barrier function which may play a significant part in the failure to eradicate UTI.

Is the value of urodynamics undermined by poor technique?: ICI-RS 2018.

INTRODUCTION: The quality of urodynamic measurements in clinical practice has been debated as a matter of concern. It is considered plausible that this has a direct bearing on patient care and the perceived value of urodynamic testing. METHODS: This is a report of the proceedings of the Think Tank: "Is the value of urodynamics undermined by poor technique?" from the Annual International Consultation on Incontinence-Research Society, which took place in June 2018 in Bristol, UK. The Think Tank discussed the evidence for deficiencies in urodynamic test quality and considered the implications of improvements for clinical diagnosis and practice. RESULTS: There is evidence that technique affects urodynamic quality, and that urodynamic practice is variable. Factors such as team skill set, technologies used, and training received will also affect the quality of urodynamic service. Questions exist regarding the influence of technique on the utility and perceived value of urodynamics. CONCLUSIONS: We suggest research questions that will provide the necessary evidence on the link between technique, reporting, and outcome, and clarify the role of good practice in the utility of urodynamic testing.

Comparison of air-filled and water-filled catheters for use in cystometric assessment.

INTRODUCTION AND HYPOTHESIS: To determine whether pressure readings measured with air-filled catheter (AFC) and water-filled catheter (WFC) systems are equivalent during cystometric assessment, especially in case of pressure measurements at Valsalva manoeuvres and coughs. METHODS: Twenty-five subjects were recruited. The commercially available 7-Fr TDOC AFC, which simultaneously reads water and air pressures in the bladder and rectum, was used to compare filling and voiding data recordings. Data were compared using paired t-tests, Bland-Altman plots and linear correlation methods, respectively. RESULTS: Pressure readings measured by the two systems showed a good correlation at Valsalva manoeuvres [R2 = 0.988, 0.968 for vesical pressure (Pves) and abdominal pressure (Pabd), respectively] and at coughs (R2 = 0.972, 0.943 for Pves and Pabd, respectively). There was a statistically significant difference between the two different measurement modalities at coughs (p < 0.01), initial resting pressure (p < 0.01) and the maximum pressure at detrusor overactivity (p < 0.01). This indicated that the difference between the two measurement modalities during Valsalva manoeuvres could reach up to 5.2 cmH2O and 8.1 cmH2O in Pves and Pabd measurements, respectively. During coughs, the difference could reach up to 20 cmH2O and 19.5 cmH2O in Pves and Pabd measurements, respectively. CONCLUSIONS: Pressure recordings from AFC and WFC systems appear to be interchangeable for some urodynamics parameters such as Pves at Valsalva manoeuvres if the baseline pressure is compensated, but not for fast-changing pressure signals such as coughs. This has to be considered when pressures are being taken with the AFC.

Development and initial psychometric properties of the 'ICIQ-Cog': a new assessment tool to measure the disease-related impact and care effort associated with incontinence in cognitively impaired adults.

OBJECTIVES: To develop a new assessment tool, the ICIQ-Cog, to measure the disease-related impact of incontinence in cognitively impaired adults and the effort associated with the care of this population, and to present the initial psychometric properties of this tool and outline the possible clinical implications. PARTICIPANTS AND METHODS: The ICIQ-Cog consists of two scales: a 12-item scale measuring disease-specific bother (ICIQ-Cog-P) and a four-item scale assessing efforts associated with care of people with incontinence and cognitive impairment (ICIQ-Cog-C). Data on 60 nursing home residents with incontinence and cognitive impairment were obtained in a test-retest research design. The psychometric properties of the ICIQ-Cog were examined using a combination of classic and item response theory methods. RESULTS: Factor analyses resulted in a three-factor solution for the ICIQ-Cog-P, with interrelated factors. Rasch analysis showed a good model fit when collapsing response categories. The ICIQ-Cog-C fitted to one dimension. The ICIQ-Cog tool provided reliable measures in terms of internal consistency (0.69-0.82) and retest reliability (0.71-0.83). The preliminary results on external validity showed that the ICIQ-Cog assessed disease-specific aspects linked to the group of cognitively impaired people with incontinence. CONCLUSION: The ICIQ-Cog tool has appropriate psychometric and clinometric properties and is therefore useful for making decisions about treatment in cognitively impaired adults with incontinence.

The AdVance and AdVanceXP male sling in urinary incontinence: is there a difference?

PURPOSE: To compare the efficacy and perioperative complications of the AdVanceXP with the original AdVance male sling. METHODS: We retrospectively enrolled 109 patients with an AdVance and 185 patients with an AdVanceXP male sling. The baseline characteristics and complication rates were analyzed retrospectively. Functional outcome and quality of life were evaluated prospectively by standardized, validated questionnaires. The Chi2-test for categorical and Mann-Whitney U test for continuous variables were performed to identify heterogeneity between the groups. RESULTS: Regarding operation time, there was no significant difference between the slings (p = 0.146). The complication rates were comparable in both groups except for postoperative urinary retention. This occurred significantly more often in patients with the AdVanceXP (p = 0.042). During follow-up, no differences could be identified regarding ICIQ-SF, PGI or I-QoL or number of pad usage. CONCLUSIONS: The AdVance and AdVanceXP are safe and effective treatment options for male stress urinary incontinence. However, the innovations of the AdVanceXP sling did not demonstrate a superiority over the original AdVance sling regarding functional outcome.

Current controversies in urinary tract infections: ICI-RS 2017.

AIMS: The current definition of urinary tract infection (UTI) relies on laboratory and clinical findings, which may or may not be relevant, depending upon the patient group under consideration. This report considers the utility of current definitions for UTI in adults with and without underlying neurological conditions in order to identify gaps in current understanding and to recommend directions for research. METHODS: This is a consensus report of the proceedings of Think Tank TT3: "How do we define and when do we treat UTI in neurological and non-neurological adult patients?" from the annual International Consultation on Incontinence-Research Society (ICI-RS), June 8-10, 2017 (Bristol, UK). RESULTS: Evidence considering the definitions of UTI in patients with and without neurological diseases was reviewed and synthesized. We examined research on laboratory methods and clinical definitions, focusing on specific cut-off values for the quantification of significant bacteriuria, and leucocyturia. Several areas were identified, mostly related to the lack of evidence-based definitions of significant bacteriuria for different patient groups, as well as uncertainties about the role of inflammatory biomarkers, and non-specific symptoms and signs. CONCLUSIONS: One of the biggest challenges in clinical practice is to discriminate between asymptomatic bacteriuria and symptomatic UTI. Future research should concentrate on risk factors for developing symptomatic UTI in different patient groups. Targeted investigations for specific populations, such as the frail elderly, and patients with neurogenic bladder dysfunction, are still needed.
