Development of a prediction model in female pure or predominant urge urinary incontinence: a retrospective cohort study.

Background: Urinary incontinence is a prevalent form of pelvic floor dysfunction, with a non-negligible impact on a patient's quality of life. There are several treatment options, varying from conservative to invasive. The aim of this study is to predict treatment outcomes of pure or predominant urge urinary incontinence (UUI) in women to support shared decision-making and manage patient expectations. Methods: Data on patient characteristics, disease history, and investigations of 512 consecutive women treated for UUI in three hospitals in the Netherlands were retrospectively collected. The predicted outcome was the short-term subjective continence outcome, defined as patient-reported continence 3 months after treatment categorized as cure (no urinary leakage), improvement (any degree of improvement of urinary leakage), and failure (no improvement or worsening of urinary leakage). Multivariable ordinal regression with backward stepwise selection was performed to analyze association between outcome and patient's characteristics. Interactions between patient characteristics and treatment were added to estimate individual treatment benefit. Discriminative ability was assessed with the ordinal c-statistic. Results: Conservative treatment was applied in 12% of the patients, pharmacological in 62%, and invasive in 26%. Subjective continence outcome was cure, improvement, and failure in 20%, 49%, and 31%, respectively. Number of incontinence episodes per day, voiding frequency during the day, subjective quantity of UI, coexistence of stress urinary incontinence (SUI), night incontinence, and bladder capacity and the interactions between these variables were included in the model. After internal validation, the ordinal c-statistic was 0.699. Conclusions: Six variables were of value to predict pure or predominant UUI treatment outcome in women. Further development into a comprehensive set of models for the use in various pelvic floor disorders and treatments is recommended to optimize individualized care. This model requires external validation before implementation in clinical practice.

Salvage radiotherapy after radical prostatectomy: Long-term results of urinary incontinence, toxicity and treatment outcomes.

PURPOSE: For patients with local recurrent disease after radical prostatectomy (35-54%) salvage radiotherapy (SRT) is the treatment of choice. In the post prostatectomy setting, SRT may impose risk at increased toxicity. As data on long-term toxicity, especially on urinary incontinence, are scarce, we report on the long-term treatment outcomes, toxicity and urinary incontinence rates after SRT. MATERIALS AND METHODS: Patients with biochemically recurrent prostate cancer after radical prostatectomy, who were treated with SRT (3D-CRT) at our institution between 1998 and 2012, were included in this retrospective cohort analysis. Primary endpoint was urinary incontinence rate. Secondary endpoints were acute and late grade ≥2 genitourinary (GU) and gastrointestinal (GI) toxicity rates, biochemical progression-free survival (bPFS), distant metastasis-free survival (DMFS), disease specific survival (DSS), and overall survival (OS). RESULTS: 244 patients were included. Median follow-up after SRT was 50 months (range: 4-187 months). Before start of SRT 69.7% of patients were continent for urine. After SRT de novo urinary incontinence complaints (grade ≥ 1) occurred in the respective acute and late phase in 6.1% and 17.6% of patients. Respective acute grade ≥2 GU and GI toxicity was 19.2% and 17.6%. Late grade ≥2 toxicity for GU was 29.9% and for GI was 21.3%, respectively. The respective 5-year bPFS, OS, DSS and DMFS rates were 47.6%, 91.8%, 98.8% and 80.5%. CONCLUSIONS: Experience at our institution with SRT demonstrates that this results in good long-term biochemical control. However, toxicity and urinary incontinence rates were high.

Heterogeneity in reporting on urinary outcome and cure after surgical interventions for stress urinary incontinence in adult neuro-urological patients: A systematic review.

AIMS: To describe all outcome parameters and definitions of cure used to report on outcome of surgical interventions for stress urinary incontinence (SUI) in neuro-urological (NU) patients. METHODS: This systematic review was performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The study protocol was registered and published (CRD42016033303; http://www.crd.york.ac.uk/PROSPERO). Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov were systematically searched for relevant publications until February 2017. RESULTS: A total of 3168 abstracts were screened. Seventeen studies reporting on SUI surgeries in NU patients were included. Sixteen different outcome parameters and nine definitions of cure were used. Six studies reported on objective outcome parameters mainly derived from urodynamic investigations. All studies reported on one or more subjective outcome parameters. Patient-reported pad use (reported during interview) was the most commonly used outcome parameter. Only three of 17 studies used standardized questionnaires (two on impact of incontinence and one on quality of life). Overall, a high risk of bias was found. CONCLUSIONS: We found a considerable heterogeneity in outcome parameters and definitions of cure used to report on outcome of surgical interventions for SUI in NU patients. The results of this systematic review may begin the dialogue to a future consensus on this topic. Standardization of outcome parameters and definitions of cure would enable researchers and clinicians to consistently compare outcomes of different studies and therapies.

The validation of the Dutch SF-Qualiveen, a questionnaire on urinary-specific quality of life, in spinal cord injury patients.

BACKGROUND: Optimizing the patients' quality of life is one of the main goals in the urological management of spinal cord injury (SCI) patients. In this study we validated the Dutch SF-Qualiveen, a short questionnaire that measures the urinary-specific quality of life, in SCI patients. No such measure is yet available for this patient group. METHODS: In 2015-2016 SCI patients with urinary symptomatology who visited the outpatient clinics of Urology at the Erasmus Medical Centre and Rehabilitation at Rijndam Revalidation completed the SF-Qualiveen and UDI-6 during the visit and 1-2 weeks later. The UDI-6, a urinary tract symptom inventory, served as gold standard. Controls, recruited from the Otolaryngology outpatient clinic, completed the questionnaires once. Content-, construct-, and criterion validity and reliability (internal consistency and reproducibility) of the SF-Qualiveen were determined. RESULTS: Fifty seven SCI patients and 50 controls were included. 12 SCI patients asserted that the SF-Qualiveen covered their bladder problems (good content validity). Patients' SF-Qualiveen scores being positively associated with severity of urinary symptoms and patients' scores being higher than those of controls indicated good construct validity. The positive association that was found between SF-Qualiveen and UDI-6 in patients (r = 0.66-0.67, P < 0.001) and controls (r = 0.63, P < 0.001) confirmed good criterion validity. Internal consistency (Cronbach's alpha 0.89-0.92) and reproducibility (intraclass correlation coefficient 0.94) of the SF-Qualiveen were good. CONCLUSIONS: The Dutch SF-Qualiveen is a valid and reliable tool to measure the urinary-specific quality of life in SCI patients.

A Quality Assessment of Patient-Reported Outcome Measures for Sexual Function in Neurologic Patients Using the Consensus-based Standards for the Selection of Health Measurement Instruments Checklist: A Systematic Review.

CONTEXT: Impaired sexual function has a significant effect on quality of life. Various patient-reported outcome measures (PROMs) are available to evaluate sexual function. The quality of the PROMs to be used for neurologic patients remains unknown. OBJECTIVE: To systematically review which validated PROMs are available to evaluate sexual function in neurologic patients and to critically assess the quality of the validation studies and measurement properties for each identified PROM. EVIDENCE ACQUISITION: A systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. The included publications were assessed according to the Consensus-Based Standards for the Selection of Health Measurement Instruments checklist. EVIDENCE SYNTHESIS: Twenty-one studies for PROMs regarding sexual function were identified for the following patient groups: spinal cord injury (11 studies), multiple sclerosis (MS; 6 studies), Parkinson's disease (2 studies), traumatic brain injury (1 study), and epilepsy (1 study). The evidence for the quality of PROMs was found to be variable, and overall evaluation of measurement properties was lacking in 71% of the studies. The measurement error and responsiveness were not studied in any of the publications. CONCLUSIONS: Several PROMs have been identified to evaluate sexual function in neurologic patients. Strong evidence was found only for the Multiple Sclerosis Intimacy and Sexuality Questionnaire-15 and Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 for patients with MS, although evidence was lacking for certain measurement properties as well. Future research should focus on identifying relevant PROMs and establishing adequate quality for all measurement properties in studies with high methodological quality. PATIENT SUMMARY: A quality assessment of patient-reported outcome measures (PROMs) for sexual function in neurologic patients was made. The evidence found for good PROMs was limited. Studies with high methodological quality are needed to improve the quality of PROMs to evaluate sexual function in neurologic patients.

The urinary-specific quality of life of multiple sclerosis patients: Dutch translation and validation of the SF-Qualiveen.

AIMS: The SF-Qualiveen is a short questionnaire that measures the impact of urinary symptoms on the quality of life of patients with urological dysfunction due to neurological disorders. The aim of this study is to translate, culturally adapt and validate a Dutch version of the SF-Qualiveen for use in Multiple Sclerosis (MS) patients. METHODS: Cross-cultural adaptation of the original English SF-Qualiveen into Dutch was performed according to standardized guidelines. Adult MS patients with symptomatic urinary disorders who visited the Urology or Rehabilitation outpatient clinic of the Erasmus Medical Center completed the SF-Qualiveen and the Urinary Distress Inventory-6 (UDI-6), that evaluates bother caused by lower urinary tract symptoms and was used as a gold standard, at baseline and 1-2 weeks later. A control group recruited from the Otolaryngology outpatient clinic completed the questionnaires once. Reliability and validity were determined. RESULTS: Fifty MS patients and 50 controls were included. SF-Qualiveen scores in patients were higher than in controls (on a scale of 0-4: 1.73 vs. 0.34; P < 0.001). Internal consistency (Cronbach's alpha >0.8) and reproducibility (Intraclass correlation coefficients >0.8) were good for the total SF-Qualiveen. Content validity was adequate and a significant relationship between SF-Qualiveen and UDI-6 (r = 0.510-0.479, P < 0.001) confirmed good criterion validity. CONCLUSIONS: The Dutch SF-Qualiveen showed good measurement properties. We recommend its use to measure urinary-specific quality of life in MS patients in research and clinical practice in the Netherlands.

20 years experience with appendicovesicostomy in paediatric patients: Complications and their re-interventions.

AIMS: To evaluate the long-term outcome of appendicovesicostomies and to present the frequency and timing of complications needing re-intervention. METHODS: In this retrospective study we included patients in whom an appendicovesicostomy was created at our institution between 1993 and 2011. Patients with a follow-up less than 1 year were excluded. Patient characteristics and conduit-related complications requiring re-intervention were collected. RESULTS: One hundred and twenty-eight patients were included with mean age at initial surgery of 10.1 ± 3.9 years. Two thirds of the children had underlying neurogenic disease. The mean follow-up was 10.1 ± 4.8 years. All but one patient continued to use the catheterizable channel. Re-intervention for conduit-related complications was necessary in 32.0% of the patients. A second, third, and fourth re-intervention was required in respectively 10.9%, 2.3%, and 1.6%. The commonest complications were cutaneous/fascial stenosis in 14.8%, stenosis at conduit-bladder level in 9.4%, and stomal incontinence in 6.3% of the patients. The most performed re-interventions were stoma revision (in 16.4% of the patients), conduit revision (10.2%), and dilatation of a stenotic tract (4.7%). 63.3% of the re-interventions was superficial and/or endoscopic. The peak incidence of re-interventions was in the 1st year after conduit construction and decreased yearly. CONCLUSIONS: Our study gives an overview of patients and their conduits developing from prepubertal children to young adults. During a mean follow-up of 10.1 years, roughly one third of the patients needed a re-intervention. We conclude that an appendicovesicostomy is an effective and durable treatment for whom transurethral clean intermittent catheterization is not feasible. Neurourol.

Indwelling Urinary Catheter-Related Problems After Laparoscopic Radical Prostatectomy.

PURPOSE: The purpose of this study was to determine occurrence rates of catheter-related problems and their association to pertinent clinical characteristics in men with indwelling urinary catheters following laparoscopic radical prostatectomy. STUDY DESIGN: Descriptive, correlational study. SUBJECTS AND SETTING: One hundred twelve men who underwent laparoscopic radical prostatectomy between December 2010 and December 2012 at the Leiden University Medical Centre in the Netherlands were included in this study. After surgery, a Charriere 20 (20F) silicone catheter was left indwelling for 1 week. METHODS: Data were gathered from 2 sources; we reviewed participants' medical records, and participants completed a questionnaire designed for this study. Pearson χ tests were used to analyze associations between dichotomous and ordinal variables and catheter-related problems. Univariate logistic regression analyses were used to analyze the relationships between continuous factors and catheter-related problems. RESULTS: Seventy-five percent of participants reported at least 1 catheter-related problem. Univariate regression analyses revealed correlations between body weight and experiencing catheter-related problems (odds ratio [OR] = 1.050; P = .028) and between body mass index and experiencing catheter-related problems (OR = 1.159; P = .049). CONCLUSION: Indwelling catheter-related problems after laparoscopic radical prostatectomy are prevalent, and they may occur at any time during the entire period of catheter use. High body mass index and high body weight were associated with an increased likelihood of catheter-related problems following radical prostatectomy.

Maximum Urethral Closure Pressure Increases After Successful Adjustable Continence Therapy (ProACT) for Stress Urinary Incontinence After Radical Prostatectomy.

OBJECTIVE: To evaluate changes of the urethral pressure profile (UPP) after implantation of adjustable continence therapy (ProACT), a minimally invasive procedure in which 2 volume-adjustable balloons are placed periurethrally for treatment of male stress urinary incontinence. The working mechanism of the ProACT to achieve continence has not been fully understood. We hypothesized that successful treatment with ProACT improves urinary continence by inducing a significant increase in static urethral pressure. MATERIALS AND METHODS: We included patients who underwent UPP before and after ProACT implantation. UPPs were initially performed with the Brown-Wickham water perfusion method and later with the T-DOC Air-Charged catheter method. Pre- and postoperative UPPs and International Prostate Symptom Scores were evaluated. UPP measurements of successfully (no or 1 precautionary pad per day) and unsuccessfully treated patients were compared. RESULTS: Twenty-seven patients were included in the study; 23 patients were successfully and 4 patients were unsuccessfully treated. Maximum urethral closure pressure (MUCP) increased significantly from median 58.0 to 79.0 cmH2O in the successfully treated group (P = .001). Within the subgroup of unsuccessfully treated patients, MUCP did not change significantly (P = .715). The change in MUCP was statistically significantly different between the successful and unsuccessful group (P = .034). Total score of the International Prostate Symptom Scores did not change significantly after ProACT implantation (P = .097). CONCLUSION: Successful treatment with ProACT is associated with a significant increase of MUCP. This implies that increased static urethral pressure contributes to the working mechanism of the ProACT device to achieve continence.
