Bladder irrigation with tap water to reduce antibiotic use for urinary tract infections in catheter users.

OBJECTIVE: To evaluate the safety and effectiveness of bladder irrigation (BI) with tap water to reduce antibiotic use for the treatment of urinary tract infections (UTIs) in patients with recurrent UTI symptoms and to assess the treatment satisfaction of BI. PATIENTS AND METHODS: This prospective, observational study included patients with an indwelling catheter or performing clean intermittent catheterisation (CIC) who had recurrent UTI symptoms between July 2022 and March 2024. BI with tap water was used for the treatment of UTIs without systemic symptoms (e.g., fever, flank pain or delirium). Patients started daily irrigation at the onset of UTI symptoms and used a tapering schedule. The number of antibiotic treatments for UTIs, UTI incidence rate ratio (IRR), UTI-related hospitalisations, treatment satisfaction and quality of life (QoL) were compared between a 3-month period before and after BI with tap water. RESULTS: A total of 60 patients were included with a median (interquartile range) age of 64.5 (50.4-72.6) years, 66.7% were male, and 83.3% were performing CIC. Antibiotic use was decreased on average by 38.1% (IRR = 0.62; P = 0.016) and catheter-associated UTIs by 37.9% (IRR = 0.62; P = 0.005). No increase was observed in the incidence of UTIs with systemic symptoms or UTI-related hospitalisations. In addition, no differences were observed in the health-related QoL. The majority of patients were positive about the subjective effectiveness (81%), ease of use (86%) and overall satisfaction (85%) of BI with tap water. CONCLUSION: These findings emphasise the potential of BI with tap water as a promising and patient-friendly alternative for the treatment of UTIs in patients with urinary catheters. BI with tap water significantly reduces antibiotic use and UTI incidence in patients with recurrent UTIs and is a safe and patient-friendly alternative that can be easily implemented in the management of UTIs.

Two-Staged Sacral Neuromodulation for the Treatment of Nonobstructive Urinary Retention: A Multicenter Study Assessing Predictors of Success.

OBJECTIVES: The aims of this study were to 1) determine the success rate of the tined lead test phase in patients with nonobstructive urinary retention (NOUR), 2) determine predictive factors of a successful test phase in patients with NOUR, and 3) determine long-term treatment efficacy and satisfaction in patients with NOUR. MATERIALS AND METHODS: The first part was a multicenter retrospective study at two centers in The Netherlands. Patients with NOUR received a four-week tined lead test phase. Success was defined as a ≥50% reduction of clean intermittent catheterization frequency or postvoid residual. We analyzed possible predictors of success with multivariable logistic regression. Second, all patients received a questionnaire to assess efficacy, perceived health (Patient Global Impression of Improvement), and treatment satisfaction. RESULTS: This study included 215 consecutive patients (82 men and 133 women) who underwent a tined lead test phase for the treatment of NOUR. The success rate in women was significantly higher than in men, respectively 62% (83/133) and 22% (18/82, p < 0.001). In women, age per ten years (odds ratio [OR] 0.74, 95% CI: 0.59-0.93) and a history of psychiatric illness (OR 3.92, 95% CI: 1.51-10.2), including posttraumatic stress disorder (PTSD), significantly predicted first stage sacral neuromodulation (SNM) success. In men, age per ten years (OR 0.43, 95% CI: 0.25-0.72) and previous transurethral resection of the prostate and/or bladder neck incision (OR 7.71, 95% CI: 1.43-41.5) were significant predictors of success. Conversely, inability to void during a urodynamic study (for women, OR 0.79, 95% CI: 0.35-1.78; for men, OR 3.06, 95% CI: 0.83-11.3) was not predictive of success. Of the patients with a successful first stage, 75% (76/101) responded to the questionnaire at a median follow-up of three years. Of these patients, 87% (66/76) continued to use their SNM system, and 92% (70/76) would recommend SNM to other patients. CONCLUSIONS: A history of psychiatric illness, including PTSD, in women with NOUR increased the odds of first stage SNM success 3.92 times. A previous transurethral resection of the prostate and/or bladder neck incision in men increased the odds of success 7.71 times. In addition, a ten-year age increase was associated with an OR of 0.43 in men and 0.74 in women, indicating a 2.3- and 1.3-times decreased odds of success, respectively.

Neurogenic bowel dysfunction score in spinal cord-injured patients: translation and validation of the Dutch-language NBD score.

STUDY DESIGN: This is a prospective validation study. OBJECTIVES: The neurogenic bowel dysfunction (NBD) score is a widely used symptom-based questionnaire evaluating bowel dysfunction and its impact on quality of life (QoL) in spinal cord-injured patients. This study aimed to translate and validate a Dutch-language NBD score in patients with SCI. SETTING: Patients with SCI visiting the urology department or general practitioner (GP) in Rotterdam, the Netherlands. METHODS: Standardized guidelines were followed for the translation and validation process of the NBD score. Adult patients with SCI visiting our urology department were asked to participate by filling in a set of questionnaires: the NBD score, the Fecal Incontinence Quality of Life scale (FIQL), the Fecal Incontinence Severity Index (FISI), and the European Quality of life 5-Dimension 3-Level questionnaire (EQ-5D-3L) at baseline and 1-2 weeks afterward. A control group recruited at a GP office completed the questionnaires once. The following measurement properties were evaluated: content validity, internal consistency, reproducibility, criterion-, and construct validity. RESULTS: Fifty-eight patients and 50 references were included. Content validity was adequate, internal consistency was moderate (Cronbach's alpha 0.56 and 0.30) and reproducibility was adequate (ICC 0.87). Criterion validity was confirmed; NBD score correlated significantly with the FIQL, FISI, and EQ-5D-3L. NBD scores in the patient group were significantly higher than in references, demonstrating good construct validity. CONCLUSIONS: The Dutch-language version of the NBD score showed moderate to good measurement properties, and therefore is a reliable tool to measure bowel dysfunction in patients with SCI. We recommend standardized usage of this questionnaire for clinical evaluation and research purposes.

Kilohertz alternating current neuromodulation of the pudendal nerves: effects on the anal canal and anal sphincter in rats.

The first two objectives were to establish which stimulation parameters of kilohertz frequency alternating current (KHFAC) neuromodulation influence the effectiveness of pudendal nerve block and its safety. The third aim was to determine whether KHFAC neuromodulation of the pudendal nerve can relax the pelvic musculature, including the anal sphincter. Simulation experiments were conducted to establish which parameters can be adjusted to improve the effectiveness and safety of the nerve block. The outcome measures were block threshold (measure of effectiveness) and block threshold charge per phase (measure of safety). In vivo, the pudendal nerves in 11 male and 2 female anesthetized Sprague Dawley rats were stimulated in the range of 10 Hz to 40 kHz, and the effect on anal pressure was measured. The simulations showed that block threshold and block threshold charge per phase depend on waveform, interphase delay, electrode-to-axon distance, interpolar distance, and electrode array orientation. In vivo, the average anal pressure during unilateral KHFAC stimulation was significantly lower than the average peak anal pressure during low-frequency stimulation (p < 0.001). Stimulation with 20 kHz and 40 kHz (square wave, 10 V amplitude, 50% duty cycle, no interphase delay) induced the largest anal pressure decrease during both unilateral and bilateral stimulation. However, no statistically significant differences were detected between the different frequencies. This study showed that waveform, interphase delay and the alignment of the electrode along the nerve affect the effectiveness and safety of KHFAC stimulation. Additionally, we showed that KHFAC neuromodulation of the pudendal nerves with an electrode array effectively reduces anal pressure in rats.

Acute effect of sacral neuromodulation for treatment of detrusor overactivity on urodynamic parameters.

AIM: The aim of this study is to evaluate the acute effects of sacral neuromodulation (SNM) on various urodynamic parameters. METHODS: Patients with overactive bladder and detrusor overactivity (DO) who were planned for percutaneous nerve evaluation (PNE) were included. Directly after the PNE, a urodynamic study (UDS) was performed. The stimulation was turned off during the first UDS (UDS 1), and during the second filling cycle, stimulation was turned on (UDS 2). The UDS was followed by a test phase of 1 week and the bladder diaries were evaluated during an outpatient clinic visit. Primary outcome measures were the differences in UDS parameter values with SNM off and on. RESULTS: Ten female patients were included in the study and completed the study protocol. Eight patients showed ≥50% improvement of symptoms following a test phase. There were no differences between UDS 1 and UDS 2 in the UDS parameters; bladder volume at first sensation, bladder volume at first DO, highest DO pressure, bladder capacity, maximum flow rate, and pressure at maximum flow rate. DISCUSSION: None of the aforementioned urodynamic parameters was influenced by acute SNM in patients who responded to SNM. To the best of our knowledge, this is the first study investigating the acute effects of SNM on bladder function.

Whole brain 7T-fMRI during pelvic floor muscle contraction in male subjects.

AIM: The primary aim of this study is to demonstrate that 7-tesla functional magnetic resonance imaging (7T-fMRI) can visualize the neural representations of the male pelvic floor in the whole brain of a single subject. METHODS: In total, 17 healthy male volunteers (age 20-47) were scanned in a 7T-MRI scanner (Philips Achieva). The scanning protocol consisted of two functional runs using a multiband echo planar imaging sequence and a T1-weighted scan. The subjects executed two motor tasks, one involving consecutive pelvic floor muscle contractions (PFMC) and a control task with tongue movements. RESULTS: In single subjects, results of both tasks were visualized in the cortex, putamen, thalamus, and the cerebellum. Activation was seen during PFMC in the superomedial and inferolateral primary motor cortex (M1), supplementary motor area (SMA), insula, midcingulate gyrus (MCG), putamen, thalamus, and in the anterior and posterior lobes of the cerebellum. During tongue movement, activation was seen in the inferolateral M1, SMA, MCG, putamen, thalamus, and anterior and posterior lobes of the cerebellum. Tongue activation was found in the proximity of, but not overlapping with, the PFMC activation. Connectivity analysis demonstrated differences in neural networks involved in PFMC and tongue movement. CONCLUSION: This study demonstrated that 7T-fMRI can be used to visualize brain areas involved in pelvic floor control in the whole brain of single subjects and defined the specific brain areas involved in PFMC. Distinct differences between brain mechanisms controlling the pelvic floor and tongue movements were demonstrated using connectivity analysis.

Outcome and complications of adjustable continence therapy (ProACTTM ) in the treatment of urinary incontinence after transurethral resection of the prostate: A multicenter study.

AIM: To evaluate the outcome of adjustable continence balloons in the treatment of stress urinary incontinence (SUI) after transurethral resection of the prostate (TURP). METHODS: In two tertiary centers, adjustable continence balloons were implanted in 29 patients with post-TURP SUI between 2007 and 2018. Endpoints of this retrospective multicenter study were patient-reported changes in pad count and complications. Dry was defined as no pad or one security pad. RESULTS: Preoperative urinary incontinence was mild in 7 (24%), moderate in 12 (41%), and severe in 10 (35%) patients. The median follow-up duration was 21 (interquartile range [IQR], 11-43) months. Within 30 days postoperatively, a Clavien-Dindo grade less than or equal to II complication occurred in 24% of the patients. Reintervention rate was 24%. Six and 12 months after implantation, the International Prostate Symptom Score (IPSS) quality-of-life item improved significantly from 5 (IQR, 5-6) preoperatively to 3 (IQR, 1-4.5) and 1 (IQR, 0-3), respectively. At last visit (median 21 months after implantation), the outcome on continence had improved in 76% of the patients, including, 45% dry patients. After a median follow-up of 28 months (IQR, 13-63; N = 23), all but one patient reported improvement on the Patient Global Impression of Improvement (PGI-I) scale. In detail, 10 patients reported "very much better" condition compared with before the implantation, 10 patients "much better," two patients "a little better," and one patient "no change." Daily pad use decreased from three (IQR, 2-5) to one (IQR, 0-2) pads/day (P < 0.001). CONCLUSIONS: This is hitherto, the first study reporting results of adjustable continence balloons in the treatment of post-TURP SUI. The therapy was found to be safe and efficient. The majority of our study population reported improvement on their condition and greater than or equal to 50% reduction in daily pad use.

The validation of the Dutch OAB-q SF: An overactive bladder symptom bother and health-related quality of life short-form questionnaire.

AIMS: The overactive bladder quality of life short-form questionnaire (OAB-q SF) evaluates both symptom bother and health-related quality of life in patients with OAB, a highly prevalent disease. The objective of this study was to translate and validate a Dutch version of the OAB-q SF. METHODS: The translation into Dutch and validation process of the OAB-q SF was performed according to standardized guidelines. Patients with OAB who visited the department of Urology outpatient clinic completed the questionnaires OAB-q SF, European Quality of life 5-Dimension 5-Level questionnaire (EQ-5D-5L), Urogenital Distress Inventory 6 (UDI-6), and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) at baseline (test) and 2 weeks later (retest). A reference group from the department of Allergology outpatient clinic completed the same questionnaires once. The evaluated measurement properties included content validity, internal consistency, reproducibility, criterion validity, and construct validity. RESULTS: Fifty-two patients were included in the study group and 51 references were included. The content validity was adequate and the internal consistency was excellent (Cronbach's α > 0.80). The reproducibility was good with intraclass correlation coefficients higher than 0.70. Patient's OAB-q SF scores were moderately to strongly correlated with the UDI-6, ICIQ-OAB, and the EQ-5D-5L confirming the criterion validity. A good construct validity was demonstrated with significant higher scores of the OAB-q SF score in patients compared to references. CONCLUSIONS: The Dutch OAB-q SF is a reliable and valid measure to evaluate symptom bother and health-related quality of life in patients with OAB.

Contemporary management and outcome of myelomeningocele: the Rotterdam experience.

OBJECTIVE: Myelomeningocele (MMC) is the most common form of spina bifida, with a lifelong impact on the quality of life for infants born with this condition. In recent decades, fetal surgery has evolved from an experimental therapy to standard of care for many centers in the world. In this study, the authors aimed to provide an overview of the current management and outcomes for infants with MMC managed at their institution. This then provides a center-specific historical cohort for comparison with future antenatal-treated MMC cases. METHODS: This is a retrospective, single-institution cohort study including all consecutive MMC cases between January 1, 2000, and June 1, 2018, at Erasmus MC. Outcome data included closure of the defect (location, timing, and surgical parameters), hydrocephalus management, Chiari malformation type II (CMTII) management, incidence of spinal cord tethering and outcome, motor outcomes, and continence. RESULTS: A total of 93 patients were included with predominantly lumbosacral lesions. Two patients died during follow-up. Hydrocephalus was present in 84%, with a 71% ventriculoperitoneal shunt reoperation rate. Surgery was performed in 12% for a tethered spinal cord at a mean age of 8 years. Decompression surgery was performed in 3 patients for CMTII. Special education in 63% was significantly associated with hydrocephalus (p < 0.015). Nineteen percent of patients were able to walk independently, and 47% were nonambulators. Social continence for urine was obtained in 75% of patients, 4% had fecal incontinence. CONCLUSIONS: This study provides an overview of current MMC outcomes at the authors' center and will serve as a historical cohort for comparison with future fetal surgery cases operated on at the center in the coming years. Apart from a relatively low surgical untethering rate, the authors' outcome data are comparable to those in the literature. Hydrocephalus is highly prevalent in postnatally treated MMC patients; in this study as in much of the literature, hydrocephalus is correlated with a low cognitive function. Fetal surgery for MMC halves the need for shunt treatment in a select group of MMC pregnancies, constituting a major indication for us to undergo the transition to a fetal surgery center. The fetal benefits of open antenatal surgery for MMC are well established, yet long-term data on especially tethered spinal cord are eagerly awaited.

Outcome and complications of adjustable continence therapy (ProACT™) after radical prostatectomy: 10 years' experience in 143 patients.

AIMS: To evaluate our outcomes of the adjustable continence balloons ProACT™ for the treatment of male stress urinary incontinence after radical prostatectomy. METHODS: Between May 2007-August 2016 the ProACT™ was implanted in 143 patients without a history of radiotherapy. Endpoints were patient-reported changes in pad counts and complications. Treatment was considered successful if no pad or just one "security" pad per day sufficed, and improved if daily pad use was reduced by ≥50%. RESULTS: Incontinence before implantation was mild in 36 (25%), moderate in 57 (40%), and severe in 50 (35%) patients. Complications within 30 days were classified by the Clavien-Dindo classification; eight (5.6%) grade I, three (2.1%) grade II, three (2.1%) grade IIIb, and 129 (90.2%) patients had no complication. Revision was done in 43 (30%) patients. The IPSS quality of life item improved significantly from 5.0 (IQR 4.0-5.0) preoperative to 2.0 (IQR 1.0-4.0) and 1.0 (IQR 0.0-3.0) 6 and 12 months after implantation, respectively. After a median follow up of 56 months (range 28 to 79, n = 112), 72 (64%) patients were improved, including 51 (45%) patients were successful. Daily pad use decreased from 3.0 to 1.0 (67% reduction). The median outcome on the Patient Global Impression of Improvement scale was "much better," and 97 (87%) patients perceived improvement. CONCLUSIONS: The minimally invasive ProACT™ device showed a clear beneficial continence outcome in patients with stress urinary incontinence after radical prostatectomy. The majority of the patients were satisfied and perceived improvement ≥50% on daily pad use on the long term.

The Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-15): Validation of the Dutch version in patients with multiple sclerosis and spinal cord injury.

AIMS: The Multiple Sclerosis Intimacy and Sexuality Questionnaire (MSISQ-15) evaluates symptoms of sexual dysfunction in patients with multiple sclerosis (MS). The objective of this study was to provide and validate a Dutch version of the MSISQ-15 in patients with neurological disease such as MS and spinal cord injury (SCI). METHODS: The linguistic validation process of the original English MSISQ-15 into Dutch was performed according to standardized guidelines. Sexually active patients with MS or spinal cord disorders, including SCI and cauda equine syndrome, who visited a tertiary urology center or a rehabilitation center completed the MSISQ-15, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in women, or International Index of Erection Function (IIEF-15) in men at baseline (test) and 2 weeks later (retest). A reference group recruited from a general medical practice completed the questionnaires once. Data were analyzed for measurement properties. RESULTS: Fifty-three patients with MS, 49 patients with spinal cord disorder, and 50 references were included. Content validity was adequate. Internal consistency (Cronbach's alpha >0.8) and reproducibility (intraclass correlation coefficient >0.8) of the MSISQ-15 were excellent. Patients' MSISQ-15 scores were correlated with severity of symptoms of sexual dysfunction measured by PISQ-12 or IIEF-15 and confirmed positive rating for criterion validity. MSISQ-15 scores in patients were higher than in references (on a scale of 15-75: 38.9 ± 11.4 vs 21.1 ± 5.4; P < 0.001), indicating good construct validity. CONCLUSIONS: The Dutch MSISQ-15 is a reliable and valid measure to evaluate symptoms of sexual dysfunction in patients with MS or with SCI.

Urotherapy in children with dysfunctional voiding and the responsiveness of two condition-specific questionnaires.

AIMS: We sought to establish the responsiveness of the Dutch Vancouver Symptom Score for Dysfunctional Elimination Syndrome (VSSDES) and Pediatric urinary incontinence Quality of life (PinQ) questionnaires. Secondary, we evaluated the outcome of urotherapy extended for children with dysfunctional voiding (DV). METHODS: This cross-sectional multicenter study was done in one tertiary and two community hospitals. Children with DV were included, also when refractory to previous urotherapeutic treatment. The questionnaires were completed before and after urotherapy. The primary outcome measure was the responsiveness of the Dutch VSDESS and PinQ. Secondary outcome was the initial success (defined by the International Children's Continence Society) of extended urotherapy. RESULTS: Between June 2014 and May 2016, 64 children (median age 7 years, IQR 6-10) received urotherapy (median 18 weeks, IQR 11-28). In contrast to the VSSDES, the PinQ showed good responsiveness. For children and parents, respectively, the area under the ROC-curve was 0.79 (P = 0.01) and 0.72 (P = 0.03) for the PinQ and 0.50 (P = 0.98) and 0.55 (P = 0.62) for the VSSDES. Fifty children received extended urotherapy, 27 had complete, and 14 had partial response. Sixteen children had been refractory to previous treatment; four showed complete, and six showed partial response. CONCLUSION: The PinQ is able to detect clinically important changes in continence-specific quality of life after treatment. We support the use of the VSSDES questionnaire in addition to the current diagnostics for the diagnosis of DV. Extended urotherapy showed to be a successful treatment for children with DV, also for those who had received previous unsuccessful treatment.

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.

Applicability of botulinum toxin type A in paediatric neurogenic bladder management.

PURPOSE OF REVIEW: The purpose of this article is to provide an overview about the applicability of botulinum toxin type A (BTX-A) in paediatric neurogenic bladder based on the recently published literature combined with hypothetical notes and future perspectives. RECENT FINDINGS: The indications, clinical outcomes, urodynamic outcome parameters and cost-effectiveness are presented from recent publications. Also, alternative routes of application of BTX-A in the bladder are discussed as well as the influence of BTX-A on conservative and invasive treatment. SUMMARY: Intradetrusor BTX-A injections for neurogenic bladder dysfunction are effective in resolving both urinary incontinence and improving urodynamic parameters in most children with a sustained response at repeated injections. In low-compliance bladders, however, if no response is seen after initial BTX-A injection, repeated injections seem to be unnecessary. Because general anaesthesia is mandatory for BTX-A injections in children, alternative routes of application have been investigated such as intravesical installation, electromotive drug application and liposomal drug delivery; however, no definite results have been found in a paediatric clinical setting.

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.

Female sexual dysfunction in multiple sclerosis: Results of a survey among Dutch urologists and patients.

AIMS: The objective of this study was to determine the prevalence of female sexual dysfunction (FSD) in patients with Multiple Sclerosis (MS) in one of the leading MS centers in the Netherlands. Furthermore, we evaluated the practice patterns of members of the Dutch Urological Association (DUA) with respect to FSD. METHODS: A self-administered Web-based questionnaire for physicians was mailed to all 467 members of the DUA. The questions covered different topics in female sexuality. For the patient survey the Female Sexual Function Index (FSFI) was used. RESULTS: The response rate of the physicians survey was 42% (n = 194). Sixty-one percent of the responders reported to ask their female patients about their sexual function. Thirty-nine percent of the physicians did not ask their patients about sexuality. The majority indicated that they lacked knowledge on FSD or found discussing sexuality not relevant for their practice. The response rate of the patient survey was 28% (n = 85). According to the FSFI questionnaire 32% of the sexually active MS patients experienced FSD. Women with FSD scored low on all subdomains of the FSFI questionnaire. In particular, desire, arousal, lubrication, and the ability to achieve orgasm were affected. CONCLUSIONS: The prevalence of FSD in MS patients in our center is about 32%. Overall, many members of the DUA do not screen for sexual dysfunction in female patients because of lack of knowledge on FSD. Better and more structured education of urologists and residents in urology on FSD in The Netherlands is urgently needed. Neurourol. Urodynam. 36:116-120, 2017. © 2015 Wiley Periodicals, Inc.

Intermittent sacral neuromodulation for idiopathic urgency urinary incontinence in women.

AIMS: SNM has been proven to be effective in the treatment of refractory UUI. Total costs and patient burden due to regular battery changes may prevent broad implementation of this treatment. The aim was to achieve a minimal improvement of 50% in incontinence episodes compared to pre-SNM by using iSNM. METHODS: This prospective cohort study was performed in women with UUI receiving treatment with SNM for a minimum of 6 months. The neurostimulator was programmed to 8 hr "on" and 16 hr "off" per day for 12 weeks. Prior to iSNM, data were collected during no SNM and cSNM. Bladder diaries and various patient reported outcome measures were collected at predetermined time points: 1-5 weeks, and 8, 12, and 16 weeks. Nonparametric tests were used for the statistical analysis. RESULTS: Of the 19 patients 63% showed an improvement of >50% of incontinence episodes during iSNM compared to pre-SNM. Bladder diary parameters showed a difference between pre-SNM and iSNM median (P-value); incontinence episodes/24 hr, 4.1-1.0 (P = 0.04), incontinence severity, 2.0-1.0 (P = 0.001), voiding episodes/24 hr, 13.0-8.0 (P = 0.001), and voided volume, 149-219 ml (P = 0.04). The UDI-6, 50.0-27.8 (P = 0.03), and the IIQ-7 scores, 50.0-9.5 (P = 0.04) also showed a significant improvement. No difference was demonstrated between iSNM and cSNM. CONCLUSIONS: Compared to pre-SNM parameters, iSNM shows an improvement in both objective and subjective outcomes. Specifically no difference was found between iSNM and cSNM, indicating that iSNM could be a feasible and cost-effective alternative. Neurourol.

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.

Real life persistence rate with antimuscarinic treatment in patients with idiopathic or neurogenic overactive bladder: a prospective cohort study with solifenacin.

BACKGROUND: Several studies have shown that the antimuscarinic treatment of overactive bladder is characterized by low long-term persistence rates. We have investigated the persistence of solifenacin in real life by means of telephonic interviews in a prospective cohort. We included both patients with idiopathic overactive bladder as well as neurogenic overactive bladder. METHODS: From June 2009 until July 2012 patients with idiopathic or neurogenic overactive bladder who were newly prescribed solifenacin were included. In total 123 subjects were followed prospectively during one year by means of four telephonic interviews, which included questions about medication use and adverse events. RESULTS: After one year 40% of all patients included was still using solifenacin, 50% discontinued and 10% was lost to follow-up. In the neurogenic group 58% was still using solifenacin versus 32% in the idiopathic group after one year (p < 0,05). The main reasons to stop solifenacin were lack of efficacy, side effects and a combination of both. CONCLUSIONS: This prospective cohort study showed a real life continuation rate of 40% after 12 months. This continuation rate is higher than found in most other studies. The use of regular telephonic evaluation might have improved medication persistence. The findings of this study also suggest that patients with neurogenic overactive bladder have a better persistence with this method of evaluation compared to patients with idiopathic overactive bladder. TRIAL REGISTRATION: This study was retrospectively registered on march 17, 2017 at the ISRCTN registry with study ID ISRCTN13129226 .

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.
