Summary of the 2024 Update of the European Association of Urology Guidelines on Neurourology. Eur Urol 2024; 85:543-555. [PMID: 38594103 DOI: 10.1016/j.eururo.2024.03.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 03/14/2024] [Accepted: 03/25/2024] [Indexed: 04/11/2024]
Abstract
BACKGROUND AND OBJECTIVE Most patients with neurourological disorders require lifelong medical care. The European Association of Urology (EAU) regularly updates guidelines for diagnosis and treatment of these patients. The objective of this review is to provide a summary of the 2024 updated EAU guidelines on neurourology. METHODS A structured literature review covering the timeframe 2021-2023 was conducted for the guideline update. A level of evidence and a strength rating were assigned for each recommendation on the basis of the literature data. KEY FINDINGS AND LIMITATIONS Neurological conditions significantly affect urinary, sexual, and bowel function, and lifelong management is required for neurourological patients to maintain their quality of life and prevent urinary tract deterioration. Early diagnosis and effective treatment are key, and comprehensive clinical assessments, including urodynamics, are crucial. Management should be customised to individual needs and should involve a multidisciplinary approach and address sexuality and fertility. Lifelong monitoring and follow-up highlight the importance of continuous care for neurourological patients. CONCLUSIONS AND CLINICAL IMPLICATIONS The 2024 EAU guidelines on neurourology provide an up-to-date overview of available evidence on diagnosis, treatment, and follow-up for neurourological patients. PATIENT SUMMARY Neurological disorders very frequently affect the lower urinary tract and sexual and bowel function and patients need lifelong management. We summarise the updated European Association of Urology guidelines on neurourology to provide patients and caregivers with the latest insights for optimal health care support.

Brain Response Induced by Peroneal Electrical Transcutaneous Neuromodulation Invented for Overactive Bladder Treatment, as Detected by Functional Magnetic Resonance Imaging. Neuromodulation 2024; 27:353-359. [PMID: 36599767 DOI: 10.1016/j.neurom.2022.11.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 10/27/2022] [Accepted: 11/28/2022] [Indexed: 01/03/2023]
Abstract
OBJECTIVES In this study, we aimed to investigate whether peroneal electrical Transcutaneous Neuromodulation invented for overactive bladder (OAB) treatment elicits activation in brain regions involved in neural regulation of the lower urinary tract. MATERIALS AND METHODS Among 22 enrolled healthy female volunteers, 13 were eligible for the final analysis. Functional magnetic resonance imaging (fMRI) (Siemens VIDA 3T; Erlangen, Germany) was used to compare the brain region activation elicited by peroneal electrical Transcutaneous Neuromodulation with the activation elicited by sham stimulation. Each subject underwent brain fMRI recording during eight 30-second periods of rest, alternating with 30-second periods of passive feet movement using the sham device, mimicking the motor response to peroneal nerve stimulation. Subsequently, fMRI recording was performed during the analogic "off-on" stimulation paradigm using peroneal electrical transcutaneous neuromodulation. Magnetic resonance imaging data acquired during both paradigms were compared using individual and group statistics. RESULTS During both peroneal electrical Transcutaneous Neuromodulation and sham feet movements, we observed activation of the primary motor cortex and supplementary motor area, corresponding to the cortical projection of lower limb movement. During peroneal electrical Transcutaneous Neuromodulation, we observed significant activations in the brain stem, cerebellum, cingulate gyrus, putamen, operculum, and anterior insula, which were not observed during the sham feet movement. CONCLUSIONS Our study provides evidence that peroneal electrical Transcutaneous Neuromodulation elicits activation of brain structures that have been previously implicated in the perception of bladder fullness and that play a role in the ability to cope with urinary urgency. Our data suggest that neuromodulation at the level of supraspinal control of the lower urinary tract may contribute to the treatment effect of peroneal electrical Transcutaneous Neuromodulation in patients with OAB.

Two-Staged Sacral Neuromodulation for the Treatment of Nonobstructive Urinary Retention: A Multicenter Study Assessing Predictors of Success. Neuromodulation 2023; 26:1823-1830. [PMID: 35690510 DOI: 10.1016/j.neurom.2022.04.042] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 03/08/2022] [Accepted: 04/26/2022] [Indexed: 10/18/2022]
Abstract
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.

J Pediatr Urol 2023; 19:753.e1-753.e8. [PMID: 37658014 DOI: 10.1016/j.jpurol.2023.08.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 08/10/2023] [Accepted: 08/14/2023] [Indexed: 09/03/2023]
Abstract
INTRODUCTION Neurogenic lower urinary tract dysfunction (NLUTD) in children can cause renal failure and urinary incontinence if not treated sufficiently. Antimuscarinics (AM) and intradetrusor botulinum toxin injections (BoNT-A) with clean intermittent catheterization (CIC) are widely used treatment options for children with NLUTD. However, a considerable number will become refractory to these treatment options. This study aimed to evaluate the efficacy and long-term outcomes of mirabegron in children with NLUTD as an add-on and as a stand-alone treatment. MATERIAL AND METHODS Patients under 18 years of age with NLUTD who were refractory to AM and/or BoNT-A and were treated with mirabegron 50 mg were retrospectively studied. Mirabegron was either used as monotherapy or in addition to AM and/or BoNT-A. Video-urodynamic studies (VUDSs) were performed before and after treatment with mirabegron. Changes in video-urodynamic parameters, the need for other NLUTD therapy during follow-up, patient-reported side effects, and urinary incontinence were outcomes of interest. RESULTS A total of 34 patients with NLUTD were included. All patients were on CIC and the median age was 13.1 years (IQR 15.9-10.3). Median follow-up was 31.4 months (IQR 57.4-11.4). Bladder compliance improved by 89.9%, from 14.9 to 28.3 ml/cm H2O (p-value<0.001). Maximum cystometric capacity, end-filling detrusor pressure, volume at first detrusor overactivity, vesicoureteral reflux, and urinary incontinence significantly improved after mirabegron. The add-on therapy group showed more significant improvements in video-urodynamic outcomes compared to the monotherapy group. The median time of requiring other NLUTD therapy was 25.5 months (IQR 39.8-14.8). None of the included patients reported side effects. CONCLUSIONS Mirabegron is an effective treatment for children with therapy-refractory NLUTD with an average efficacy of 2 years after which additional therapy is required. Despite the retrospective character of this study, our results confirm the beneficial effect of mirabegron in children with therapy-refractory NLUTD, in particular when mirabegron is used as add-on therapy in those with low-compliance bladders.

Transcutaneous Electrical Stimulation of the Abdomen, Ear, and Tibial Nerve Modulates Bladder Contraction in a Rat Detrusor Overactivity Model: A Pilot Study. Int Neurourol J 2023; 27:167-173. [PMID: 37798883 PMCID: PMC10556428 DOI: 10.5213/inj.2346144.072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Accepted: 08/17/2023] [Indexed: 10/07/2023] Open
Abstract
PURPOSE The global prevalence of overactive bladder (OAB) is estimated at 11.8%. Despite existing treatment options such as sacral neuromodulation, a substantial number of patients remain untreated. One potential alternative is noninvasive transcutaneous electrical stimulation. This form of stimulation does not necessitate the implantation of an electrode, thereby eliminating the need for highly skilled surgeons, expensive implantable devices, or regular hospital visits. We hypothesized that alternative neural pathways can impact bladder contraction. METHODS In this pilot study, we conducted transcutaneous electrical stimulation of the abdominal wall (T6-L1), the ear (vagus nerve), and the ankle (tibial nerve) of 3 anesthetized female Sprague-Dawley rats. Stimulation was administered within a range of 20 Hz to 20 kHz, and its impact on intravesical pressure was measured. We focused on 3 primary outcomes related to intravesical pressure: (1) the pressure change from the onset of a contraction to its peak, (2) the average duration of contraction, and (3) the number of contractions within a specified timeframe. These measurements were taken while the bladder was filled with either saline or acetic acid (serving as a model for OAB). RESULTS Transcutaneous stimulation of the abdominal wall, ear, and ankle at a frequency of 20 Hz decreased the number of bladder contractions during infusion with acetic acid. As revealed by a comparison of various stimulation frequencies of the tibial nerve during bladder infusion with acetic acid, the duration of contraction was significantly shorter during stimulation at 1 kHz and 3 kHz relative to stimulation at 20 Hz (P = 0.025 and P = 0.044, respectively). CONCLUSION The application of transcutaneous electrical stimulation to the abdominal wall, ear, and tibial nerve could provide less invasive and more cost-effective treatment options for OAB relative to percutaneous tibial nerve stimulation and sacral neuromodulation. A follow-up study involving a larger sample size is recommended.

Differences between brain responses to peroneal electrical transcutaneous neuromodulation and transcutaneous tibial nerve stimulation, two treatments for overactive bladder. Neurourol Urodyn 2023. [PMID: 37144657 DOI: 10.1002/nau.25197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 03/27/2023] [Accepted: 04/20/2023] [Indexed: 05/06/2023]
Abstract
OBJECTIVES To compare brain responses to peroneal electrical transcutaneous neuromodulation (peroneal eTNM®) and transcutaneous tibial nerve stimulation (TTNS), two methods for treating overactive bladder (OAB), using functional magnetic resonance imaging (fMRI). The present study was not designed to compare their clinical efficacy. MATERIALS AND METHODS This study included 32 healthy adult female volunteers (average age 38.3 years (range 22-73)). Brain MRI using 3 T scanner was performed during three 8-min blocks of alternating sequences. During each 8-min block, the protocol alternated between sham stimulation (30 s) and rest (30 s) for 8 repeats; then peroneal eTNM® stimulation (30 s) and rest (30 s) for 8 repeats; then, TTNS stimulation (30 s) and rest (30 s) for 8 repeats. Statistical analysis was performed at the individual level with a threshold of p = 0.05, family-wise error (FWE)-corrected. The resulting individual statistical maps were analyzed in group statistics using a one-sample t-test, p = 0.05 threshold, false discovery rate (FDR)-corrected. RESULTS During peroneal eTNM®, TTNS, and sham stimulations, we recorded activation in the brainstem, bilateral posterior insula, bilateral precentral gyrus, bilateral postcentral gyrus, left transverse temporal gyrus, and right supramarginal gyrus. During both peroneal eTNM® and TTNS stimulations, but not sham stimulations, we recorded activation in the left cerebellum, right transverse temporal gyrus, right middle frontal gyrus, and right inferior frontal gyrus. Exclusively during peroneal eTNM® stimulation, we observed activation in the right cerebellum, right thalamus, bilateral basal ganglia, bilateral cingulate gyrus, right anterior insula, right central operculum, bilateral supplementary motor cortex, bilateral superior temporal gyrus, and left inferior frontal gyrus. CONCLUSIONS Peroneal eTNM®, but not TTNS, induces the activation of brain structures that were previously implicated in neural control of the of bladder filling and play an important role in the ability to cope with urgency. The therapeutic effect of peroneal eTNM® could be exerted, at least in part, at the supraspinal level of neural control.

Abstract
PURPOSE The aim of this prospective 12-month follow-up study is to evaluate the persistence of the treatment effect achieved during the initial course of peroneal electrical Transcutaneous NeuroModulation (peroneal eTNM®) in patients with overactive bladder (OAB). METHODS This study enrolled 21 female patients who participated in two previous clinical studies designed to assess the efficacy and safety of peroneal eTNM®. The patients were left without subsequent OAB treatment and were invited to attend regular follow-up visits every 3 months. The patient's request for additional treatment was considered an indicator of the withdrawal of the treatment effect of the initial course of peroneal eTNM®. The primary objective was the proportion of patients with persisting treatment effect at follow-up visit 12 months after initial course of peroneal eTNM®. Descriptive statistics are presented using median, correlation analyses were computed using a nonparametric Spearman correlation. RESULTS The proportion of patients with persistent therapeutic effect of the initial course of peroneal eTNM® was 76%, 76%, 62% and 48% at 3, 6, 9 and 12 months, respectively. There was a significant correlation between patient reported outcomes and the number of severe urgency episodes with or without urgency incontinence as reported by patients at each follow-up visit (p = 0.0017). CONCLUSION The treatment effect achieved during the initial phase of peroneal eTNM® persists for at least 12 months in 48% of patients. It is likely that the duration of effects is dependent on the length of the initial therapy.

Abstract
PURPOSE We investigated the safety and efficacy of peroneal electrical transcutaneous neuromodulation using the URIS neuromodulation system in a home-based setting in comparison with standard treatment using solifenacin in treatment-naïve female patients with overactive bladder. MATERIALS AND METHODS A total of 120 patients were screened, of whom 77 were randomized in a 2:1 ratio to 12 weeks of treatment with daily peroneal electrical transcutaneous neuromodulation or solifenacin 5 mg. The primary endpoint was safety; efficacy assessments included proportion of responders, defined as subjects with ≥50% reduction in bladder diary-derived variables; Overactive Bladder-Validated 8-question Screener, and European Quality of Life-5 Dimensions questionnaire; and treatment satisfaction after 12 weeks of therapy. RESULTS Seventy-one out of 77 randomized patients completed the study. In the peroneal electrical transcutaneous neuromodulation group 6/51 (12%) patients reported a treatment-related adverse event vs 12/25 (48%) in the solifenacin group (P < .001). No clinically significant changes were observed in any other safety endpoint. The proportions of responders in the peroneal electrical transcutaneous neuromodulation group vs the solifenacin group were 87% vs 74% with respect to Patient Perception of Intensity of Urgency Scale grade 3 urgency episodes, 87% vs 75% with respect to grade 3+4 urgency episodes, and 90% vs 94% with respect to urgency incontinence episodes. In post hoc analyses we observed significant improvement over time in multiple efficacy variables in both treatment arms. CONCLUSIONS Peroneal electrical transcutaneous neuromodulation is a safe and effective method for overactive bladder treatment associated with a significantly lower incidence of treatment-related adverse events compared to solifenacin and a considerably better benefit-risk profile.

Abstract
Androgens and their receptors are present throughout the body. Various structures such as muscles, genitals, and prostate express androgen receptors. The central nervous system also expresses androgen receptors. Androgens cross the blood-brain barrier to reach these central areas. In the central nervous system, androgens are involved in multiple functions. The current study investigated in which forebrain areas androgens are expressed in the male cat. Androgen receptor immunoreactive (AR-IR) nuclei were plotted and the results were quantified with a Heidelberg Topaz II + scanner and Linocolor 5.0 software. The density and intensity of the labeled cells were the main outcomes of interest. The analysis revealed a dense distribution of AR-IR nuclei in the preoptic area, periventricular complex of the hypothalamus, posterior hypothalamic area, ventromedial hypothalamic, parvocellular hypothalamic, infundibular, and supramammillary nucleus. Numerous AR-IR cells were also observed in the dorsal division of the anterior olfactory nucleus, lateral septal nucleus, medial and lateral divisions of the bed nucleus of the stria terminalis, lateral olfactory tract nucleus, anterior amygdaloid area, and the central and medial amygdaloid nuclei. AR-IR nuclei were predominantly observed in areas involved in autonomic and neuroendocrinergic responses which are important for many physiological processes and behaviors.

Abstract
Neurogenic lower urinary tract dysfunction (NLUTD), the abnormal function of the lower urinary tract in the context of neurological pathology, has been the subject of multiple efforts worldwide for the development of clinical practice guidelines. These guidelines are based on the same body of evidence, and are therefore subject to the same gaps. For example, sexual and bowel dysfunction in the context of NLUTD, optimal renal function assessment in those who are non-ambulatory or with low muscle mass, optimal upper tract surveillance timing, and modification of diagnostic and treatment modalities for low-resource nations and communities are inadequately addressed. In addition, many aspects of the conclusions and final recommendations of the guidelines are similar. This duplicative work represents a large expenditure of time and effort, which we believe could be focused instead on evidence gaps. Here, we call for a global unified approach to create a single, resource-independent, comprehensive guidance on NLUTD, neurogenic sexual, and neurogenic bowel dysfunction. Targeted research addressing the evidence gaps should be called for and pursued. This will allow for focus to shift to filling the gaps in the evidence for future guidelines.

Abstract
Objectives Our aim was to evaluate trends and regional differences in the use of indwelling and intermittent urinary catheters in the community setting in the Netherlands from 2012 to 2021. Design and methods For this population-based cohort study, data on catheter use was collected from the Drug and Medical Devices Information System of the National Healthcare Institute of the Netherlands. This database contains information on the Dutch insured population, which was 100% of the total population in 2018. Users were divided into 12 provinces according to the Nomenclature of Territorial Units for Statistics codes. The number of catheter users was adjusted for the total population of the provinces by sex and age, and was expressed by users per 100,000 people. Negative binomial regression (NBR) was used to test for differences in clean intermittent catheter (CIC) and indwelling catheter (IDC) users across Dutch provinces. Results Between 2012 and 2021, IDC users increased by 44.6% from 41,619 to 60,172, and CIC users increased by 27.3% from 34,204 to 43,528. The greatest increases were mainly observed among IDC users over 85 years old and male CIC users over 65 years old. NBR showed significant differences for IDC and CIC users between the 12 provinces. CIC incidence was higher in Drenthe and Groningen (Northern Netherlands) compared to Zuid-Holland (Southern Netherlands). IDC incidence was higher in seven provinces dispersed throughout the Netherlands compared to Noord-Holland. Conclusion CIC and IDC users have continued to increase in recent years; this was especially observed among older men. In addition, there were regional differences in the number of CIC and IDC users; CIC was more prominent in the northern region of the Netherlands, and IDC varied between multiple provinces. Practice variation in urinary catheterization may result from patient population differences or healthcare provider preferences and their alignment with guidelines.

Abstract
Background The diagnosis of a clinically significant catheter-associated urinary tract infection (CAUTI) in patients performing clean intermittent catheterization (CIC) or with an indwelling catheter (IC) can be challenging. Objective To get an insight into the variation of the used definition, diagnosis and management of CAUTIs by relevant healthcare workers in the Netherlands. Design An online clinical scenario-based survey. Methods The survey was built in Limesurvey and distributed to healthcare workers from randomly selected urology departments, rehabilitation departments/centres and general practice offices between January and May 2022. Questions regarding their field of experience, management strategies, used guidelines and two hypothetical cases with clinical scenarios of a possible CAUTI were included. Results A total of 172 individuals participated, of which 112 completed the survey. In all, 32 individuals who completed the survey partially were also included. Participants consisted of 68 [44 urologists, 22 rehabilitation doctors (RDs) and 2 general practitioners (GPs)] doctors, 60 nurses (46 from the urology department and 14 from rehabilitation centres/departments) and 16 medical assistants (13 from urology department and 3 from GP offices). The majority consulted patients with an IC or on CIC on a daily/weekly or monthly basis. In all, 35 urologists (79.5%), 9 RDs (40.9%), 21 (45.7%) nurses in the urology department and 6 (42.9%) nurses from a rehabilitation department/centre indicated bladder irrigation as a treatment option for prevention/treatment of CAUTIs, treatment of symptoms or treatment of blockage of the catheter. In the clinical scenarios presented, treatment discrepancies were seen between subspecialties and healthcare workers. Various guidelines were named for the definition of CAUTIs. Conclusion A considerable variation in diagnoses and management of CAUTIs between the healthcare workers involved was seen. Uniformity in diagnosing and managing CAUTIs, to prevent overtreatment and possible resistance to antibiotics, is advised. Suitable multidisciplinary guidelines are preferred.

Abstract
CONTEXT Neurourological patients often encounter bacteriuria without any symptoms or may experience symptoms suspicious of urinary tract infections (UTIs). However, there is a lack of guidelines that unequivocally state the definition of UTIs in this specific patient group. OBJECTIVE To present all used definitions of UTIs in neurourological patients. EVIDENCE ACQUISITION This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were identified by electronic search of Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov without a time limitation (last search September 2020) and by screening of reference lists and reviews. The occurrences of the various UTI definitions were counted and the frequencies calculated. EVIDENCE SYNTHESIS After screening 7164 abstracts, we included 32 studies enrolling a total of 8488 patients with a neurourological disorder who took part in an interventional clinical study. UTI definitions were heterogeneous. The concordance to predefined definitions was low. CONCLUSIONS Interventional clinical studies rarely report specific definitions for UTIs, and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed. PATIENT SUMMARY Patients suffering from neurological disorders often experience symptoms in their lower urinary tract that resemble urinary tract infections. Furthermore, they can have positive urine cultures without symptoms (the so-called asymptomatic bacteriuria). However, clinical studies rarely report specific definitions for urinary tract infections, and when it is done, they are heterogeneous. A generally accepted urinary tract infection definition for neurourological patients is urgently needed. TAKE HOME MESSAGE: Interventional clinical studies on neurourological patients rarely report specific definitions for urinary tract infections (UTIs), and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed.

Abstract
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.

Abstract
INTRODUCTION Chronic urinary retention is a common lower urinary tract disorder, mostly neurogenic or idiopathic in origin. The preferred treatment is clean intermittent urinary self-catheterisation (CISC) four to six times a day. In most European countries, virtually all patients use single use catheters, which is in contrast to several countries where the use of reusable catheters is more common. The available literature on the use of reusable catheters is conflicting and until now, no randomised controlled trial with sufficient power has been performed to investigate if reusable catheters for CISC is as safe as single use catheters. METHODS AND ANALYSIS We described this protocol for a prospective, randomised controlled non-inferiority trial to investigate if the use of reusable catheters is as safe as single use catheters for CISC patients, measured by symptomatic urinary tract infections (sUTIs). Secondary objectives are adverse events due to a sUTI, urethral damage, stone formation, quality of life and patient satisfaction. A cost-effectiveness analysis will also be performed. 456 Participants will be randomised into two groups stratified for age, gender, menopausal status and (non-)neurogenic underlying disorder. The intervention group will replace the reusable catheter set every 2 weeks for a new set and replace the cleaning solution every 24 hours. The control group continues to use its own catheters. The primary outcome (amount of sUTIs from baseline to 1 year) will be tested for non-inferiority. Categorical outcome measures will be analysed using χ2 tests and quantitative outcome variables by t-tests or Mann-Whitney U tests. Two-sided p values will be calculated. ETHICS AND DISSEMINATION This protocol was reviewed and approved by the Medical Ethics Committee of the Erasmus MC (MEC 2019-0134) and will be performed according to the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) checklist for non-inferiority trials. The results of this randomised controlled non-inferiority trial will be published in a peer-reviewed journal and will be publicly available. TRIAL REGISTRATION NUMBER NL8296.

Abstract
CONTEXT Controversy still exists regarding the balance of benefits and harms for the different surgical options for neurogenic stress urinary incontinence (N-SUI). OBJECTIVE To identify which surgical option for N-SUI offers the highest cure rate and best safety without compromising urinary tract function and bladder management. EVIDENCE ACQUISITION A systematic review was performed under the auspices of the European Association of Urology Guidelines Office and the European Association of Urology Neuro-Urology Guidelines Panel according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. EVIDENCE SYNTHESIS A total of 32 studies were included. Overall, 852 neurourological patients were surgically treated for N-SUI. The treatment offered most often (13/32 studies) was an artificial urinary sphincter (AUS; 49%, 416/852) and was associated with a need for reintervention in one-third of patients. More than 200 surgical revisions were described. Overall, 146/852 patients (17%) received concomitant bladder augmentation, mainly during placement of an AUS (42%, 62/146) or autologous sling (34% of women and 14% of men). Following pubovaginal sling placement, dryness was achieved in 83% of cases. A significant improvement in N-SUI was observed in 87% (82/94) of women following placement of a synthetic midurethral sling. Efficacy after insertion of an adjustable continence therapy device (ACT 40%, proACT 60%) was reported for 38/128 cases (30%). The cure rate for bulking agents was 35% (9/25) according to 2/32 studies, mainly among men (90%). The risk of bias was highly relevant. Baseline and postoperative cystometry were missing in 13 and 28 studies, respectively. CONCLUSIONS The evidence is mainly reported in retrospective studies. More than one intervention is often required to achieve continence because of coexisting neurogenic detrusor overactivity, low compliance, or the onset of complications in the medium and long term. Urodynamic data are needed to better clarify the success of N-SUI treatment with the different techniques. PATIENT SUMMARY Our review shows that insertion of an artificial urinary sphincter for urinary incontinence is effective but is highly associated with a need for repeat surgery. Other surgical options may have lower continence rates or a risk of requiring intermittent catheterization, which patients should be informed about before deciding on surgery for their incontinence.

Abstract
Background: Our aim was to evaluate the use of indwelling, intermittent and external urinary catheters in neurogenic and non-neurogenic bladder patients in the Netherlands from 1997 to 2018. Methods: Data were retrieved from a population-based cohort containing information about the extramural use of medical devices in the insured population in the Netherlands. The insured population increased from 9.9 million people in 1997 to 17.1 million people in 2018 (64–100% of the Dutch population). Users are expressed by users per 100,000 insured people and total users, corrected for the overall Dutch population. The expenditures are corrected for inflation and expressed by total costs and costs per user. Results: During this 21-year period, indwelling catheter (IC) users doubled from 159 per 100,000 people (24,734 users) to 315 per 100,000 people (54,106 users). Clean intermittent catheter (CIC) users increased from 92 per 100,000 people (14,258 users) in 1997 to 267 per 100,000 people (45,909 users) in 2018. Of all users, 20.7% had an associated neurogenic disorder and 44.9% a non-neurogenic disorder in 2018. The total expenditure on extramural use of urinary catheters increased from 27.7 million euros in 1997 to 84.4 million euros in 2018. IC costs increased from 6.0 million euros in 1997 to 6.7 million euros in 2018, while CIC costs rose from 16.4 million euros to 74.6 million euros. Urine drainage bag costs decreased from 17.2 million in 2001 to 5.3 million in 2018. Conclusions: IC use has increased substantially over the past 21 years, despite the fact that CIC use increased as well. It seems that the main driver behind the prevalence in IC and CIC use, is the rise in incontinence care in older patients and the adaption of preferred CIC use in professional guidelines. At least one fifth of all users catheterize due to neurogenic reasons.

Abstract
AIM To obtain insight into the the use and costs of clean intermittent catheterization (CIC) in the Netherlands from 1997 to 2018. METHODS For this population-based study, data on the use and costs of disposable catheters were provided by the Drug Information Project database. This database contains information about the Dutch insured population, which increased from 9.9 to 17.1 million persons between 1997 and 2018 (64%-100% of the Dutch population). The following trends were evaluated: (1) CIC users, (2) distribution of users by gender and age-group, (3) distribution of users by neurogenic and non-neurogenic cause for CIC, (4) total costs, and (5) costs per user. Total users are adjusted for the Dutch population. Costs are corrected for inflation and expressed in euros. RESULTS Extramural use of CIC increased from 14,258 users in 1997 to 45,909 users in 2018. CIC users per 100,000 persons nearly tripled from 92 users to 267 users. Male CIC users almost quadrupled from 92 to 334 per 100,000 insured persons, whereas female users more than doubled from 91 to 201 per 100,000 insured persons. In 2018, 49% of the users had a non-neurogenic cause for CIC. Total costs increased from 16.4 million euros in 1997 to 74.6 million euros in 2018. Costs per user rose from 1151 to 1624 euros (41.1%). CONCLUSIONS The use and costs of disposable catheters in the Netherlands increased substantially over the past two decades. Non-neurogenic bladder patients represent 49% of the population on CIC, which has not been described before in the literature.

Abstract
Sex hormones, including androgens and estrogens, play an important role in autonomic, reproductive and sexual behavior. The areas that are important in these behaviors lie within the spinal cord and brainstem. Relevant dysfunctional behavior in patients with altered androgen availability or androgen receptor sensitivity might be explained by the distribution of androgens and their receptors in the central nervous system. We hypothesize that autonomic dysfunction is correlated with the androgen sensitivity of spinal cord and brainstem areas responsible for autonomic functions. In this study, androgen receptor immunoreactive (AR‐IR) nuclei in the spinal cord and brainstem were studied using the androgen receptor antibody PG21 in four uncastrated young adult male cats. A dense distribution of AR‐IR nuclei was detected in the superior layers of the dorsal horn, including lamina I. Intensely stained nuclei, but less densely distributed, were found in lamina X and preganglionic sympathetic and parasympathetic cells of the intermediolateral cell column. Areas in the caudal brainstem showing a high density of AR‐IR nuclei included the area postrema, the dorsal motor vagus nucleus and the retrotrapezoid nucleus. More cranially, the central linear nucleus in the pons contained a dense distribution of AR‐IR nuclei. The mesencephalic periaqueductal gray (PAG) showed a dense distribution of AR‐IR nuclei apart from the most central part of the PAG directly adjacent to the ependymal lining. Other areas in the mesencephalon with a dense distribution of AR‐IR nuclei were the dorsal raphe nucleus, the retrorubral nucleus, the substantia nigra and the ventral tegmental area of Tsai. It is concluded that AR‐IR nuclei are located in specific areas of the central nervous system that are involved in the control of sensory function and autonomic behavior. Furthermore, damage of these AR‐IR areas might explain related dysfunction in humans.

Abstract
Purpose Functional neuroimaging is a powerful and versatile tool to investigate central lower urinary tract (LUT) control. Despite the increasing body of literature there is a lack of comprehensive overviews on LUT control. Thus, we aimed to execute a coordinate based meta-analysis of all PET and fMRI evidence on descending central LUT control, i.e. pelvic floor muscle contraction (PFMC) and micturition. Materials and methods A systematic literature search of all relevant libraries was performed in August 2020. Coordinates of activity were extracted from eligible studies to perform an activation likelihood estimation (ALE) using a threshold of uncorrected p <0.001. Results 20 of 6858 identified studies, published between 1997 and 2020, were included. Twelve studies investigated PFMC (1xPET, 11xfMRI) and eight micturition (3xPET, 5xfMRI). The PFMC ALE analysis (n = 181, 133 foci) showed clusters in the primary motor cortex, supplementary motor cortex, cingulate gyrus, frontal gyrus, thalamus, supramarginal gyrus, and cerebellum. The micturition ALE analysis (n = 107, 98 foci) showed active clusters in the dorsal pons, including the pontine micturition center, the periaqueductal gray, cingulate gyrus, frontal gyrus, insula and ventral pons. Overlap of PFMC and micturition was found in the cingulate gyrus and thalamus. Conclusions For the first time the involved core brain areas of LUT motor control were determined using ALE. Furthermore, the involved brain areas for PFMC and micturition are partially distinct. Further neuroimaging studies are required to extend this ALE analysis and determine the differences between a healthy and a dysfunctional LUT. This requires standardization of protocols and task-execution.

Abstract
CONTEXT Transcutaneous electrical nerve stimulation (TENS) and percutaneous tibial nerve stimulation (PTNS) provide minimally invasive ways to treat idiopathic nonobstructive urinary retention (NOUR). OBJECTIVE To assess the efficacy of TENS and PTNS for treating idiopathic NOUR. EVIDENCE ACQUISITION A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Embase, Medline, Web of Science Core Collection, and the Cochrane CENTRAL register of trials were searched for all relevant publications until April 2020. EVIDENCE SYNTHESIS A total of 3307 records were screened based on the title and abstract. Eight studies met the inclusion criteria and none of the exclusion criteria. Five studies, all from the same group, reported the efficacy of PTNS and two that of TENS in adults with idiopathic NOUR. One study reported the efficacy of TENS in children with idiopathic NOUR. Objective success was defined as a ≥50% decrease in the number of catheterizations per 24 h or in the total catheterized volume in 24 h. The objective success rate of PTNS ranged from 25% to 41%. Subjective success was defined as the patient's request for continued chronic treatment with PTNS, and ranged from 46.7% to 59%. Eighty percent of women who underwent transvaginal stimulation reported an improvement such as a stronger stream when voiding. TENS in children reduced postvoid residual and urinary tract infections. CONCLUSIONS The efficacy of TENS and PTNS in the treatment of idiopathic NOUR is limited and should be verified in larger randomized studies before application in clinical practice. PATIENT SUMMARY The outcomes of transcutaneous electrical nerve stimulation and percutaneous tibial nerve stimulation for the treatment of urinary retention of unknown origin were reviewed. Whether these treatments are superior to other treatments could not be established.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic is unlike anything seen before by modern science-based medicine. Health systems across the world are struggling to manage it. Added to this struggle are the effects of social confinement and isolation. This brings into question whether the latest guidelines are relevant in this crisis. We aim to support urologists in this difficult situation by providing tools that can facilitate decision making, and to minimise the impact and risks for both patients and health professionals delivering urological care, whenever possible. We hope that the revised recommendations will assist urologist surgeons across the globe to guide the management of urological conditions during the current COVID-19 pandemic.

Abstract
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.

Abstract
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.
