RESUMEN
PURPOSE: Neurogenic stress urinary incontinence (N-SUI) is a condition with serious impact on the quality of life. There are several treatment modalities of which the artificial urinary sphincter (AUS) stands out as the most suitable technique for addressing sphincter insufficiency. In this article, the purpose is to describe practical considerations, outcomes, and complications of the artificial urinary sphincter in neurological sphincter deficiency in both males and females. METHODS: A narrative review of the current literature. RESULTS: The outcomes of AUS are reasonably good in patients with NLUTD, the surgical technique is discussed as well as the limitations and special considerations in this complex and heterogeneous patient population. CONCLUSION: The available evidence suggests that its efficacy and functional durability may be lower in patients with neurogenic lower urinary tract dysfunction (NLUTD) compared to those without neurological deficits. However, studies have shown that AUS can still provide effective and safe continence outcomes in both male and female patients, with long-term device survival rates ranging from several years to over a decade.

PURPOSE: The effect of overactive bladder (OAB) on sexual health has been evaluated extensively for women but much less for men. Therefore, the aim of this study was to evaluate the relationship between OAB and men's sexual activity and the effect of OAB on erectile dysfunction (ED) and premature ejaculation (PE) in a large representative cohort of men at the population level. METHODS: This study was based on computer-assisted web interviews that used validated questionnaires. The most recent census and the sample size estimation calculations were employed to produce a population-representative pool. RESULTS: The study included 3001 men, representative of the population in terms of age and place of residence. The frequency of sexual intercourse was higher for respondents without OAB symptoms compared with persons who had OAB (p = 0.001), but there was no association between OAB symptoms and number of sexual partners (p = 0.754). Regression models did not confirm the effect of OAB on sexual activity (odds ratio 0.993, CI 0.974-1.013, p = 0.511). Both ED and PE were more prevalent in respondents with OAB symptoms compared with persons who lacked those symptoms (p < 0.001). Importantly, the effect of OAB on ED or PE was independent of age, comorbidities, and lifestyle habits (regression coefficients of 0.13 and 0.158 for ED and PE, respectively). CONCLUSION: Overactive bladder did not significantly affect men's sexual activity, but it significantly correlated with ED and PE. Our results suggest a need in daily clinical practice to screen for OAB symptoms for persons who report ED or PE.

INTRODUCTION: The EPIC study has highlighted the prominence of nocturia as a crucial symptom of overactive bladder (OAB), intertwining OAB and nocturia with bladder, kidney, and brain functions. METHODS: Expert opinion, review. RESULTS: To truly comprehend lower urinary tract symptoms (LUTS), we must delve into the interactions among these three systems, alongside their circadian rhythms. CONCLUSION: The perception of LUTS is a result of the intricate interplay between bladder, brain, and kidney function, which may evolve across a lifetime due to the (dys)functionality of these organs.

AIMS: As people age, sleep stages and characteristics transition over time, but sleep deficits can profoundly impact health and cognitive functioning. Chronic sleep deprivation is linked to impaired attention and productivity, weakened immunity, increased risk of cardiovascular disease, obesity, and mental health disorders. Insomnia, obstructive sleep apnea syndrome, hormonal changes, nocturia, neurological disorders, and life events interfere with sleep patterns and some are linked to lower urinary tract symptoms (LUTS). This NOPIA symposium on Lifelong LUTS aimed to analyze the literature on associations between sleep and LUTS, generate ideas for future research, and explore whether there is support for the concept of lifelong LUTS in relation to changes in sleep throughout the lifespan. METHODS: An international panel of experts took part in an online meeting addressing the role of lifelong LUTS in relationship to sleep and the brain organized by the NOPIA research group. The manuscript summarizes existing literature, hypotheses, future research ideas, and clinical recommendations. RESULTS: Insomnia, sleep fragmentation, hyperarousal, and sensory processing disorders emerged as potential factors in the relationship between sleep and LUTS. Insomnia is often a persistent factor and may have been the initial symptom; however, it is often unrecognized and/or unaddressed in healthcare settings. By recognizing insomnia as a primary driver of various health issues, including nocturia, transitional care aims to address root causes and underlying problems earlier to initiate appropriate treatment. CONCLUSIONS: A multidisciplinary approach with collaboration between healthcare professionals from various disciplines, such as urology, sleep medicine, gynecology, pediatrics, and geriatrics, is needed and should include validated measurements such as the insomnia severity index and sleep and voiding diaries. Ensuring ongoing follow-up and monitoring through transitional care is crucial for individuals with persistent sleep problems and LUTS, allowing issues that arise or fluctuate over the lifespan to be addressed.

BACKGROUND: Lower urinary tract symptoms (LUTS) are highly prevalent and very bothersome. To support the best possible allocation of health care resources and to avoid unnecessary expenditures, it is important to understand and quantify the wide-ranging health care costs affecting people suffering from LUTS. We aimed at creating a foundation for exploring the cost of LUTS. METHOD: In this systematic literature review, we explored the costs of illness of the LUTS umbrella. We used the online literature review tool Silvi.ai for transparent decision-making and literature management. RESULTS: A total of 1821 original articles were screened. Forty had explored the cost of illness of a LUTS disease since 2013. The studies were conducted in 18 countries. A number of different study designs were applied, including both retrospective and prospective studies. In total, seven LUTS indications were explored. None of them focused on lifelong LUTS. None of them were conducted in infants or children. Eighty-two percent were conducted in adults and 18% in frail elderly. Most cost of illness studies focused on the cost of hospitalization and use of medicine. CONCLUSION: We have created the groundwork for understanding the cost of LUTS illness. To fully understand the cost of illness of lifelong LUTS, the main gap in research is to investigate the cost of LUTS in infants and children.

INTRODUCTION: Lower urinary tract symptoms (LUTSs) are a diverse array of urinary and pelvic dysfunctions that can emerge from childhood, extend through adulthood, and persist into older age. This narrative review aims to provide a comprehensive perspective on the continuum of LUTS and shed light on the underlying mechanisms and clinical implications that span across the lower urinary tract. METHODS: A panel of five experts from Belgium, the Netherlands, India, Denmark, and the United States participated in an intensive research to explore and pinpoint existing insights into the lifelong concept of LUTS, particularly at the pelvic level. The experts reviewed the existing literature and held a webinar to discuss their findings. RESULTS: Childhood LUTS can persist, resolve, or progress into bladder underactivity, dysfunctional voiding, or pain syndromes. The Lifelong character can be explained by pelvic organ cross-talk facilitated through complex neurological and nonneurological interactions. At the molecular level, the role of vasopressin receptors in the bladder's modulation and their potential relevance to therapeutic strategies for LUTS are explored. Frailty emerges as a parallel concept to lifelong LUTS, with a complex and synergistic relationship. Frailty, not solely an age-related condition, accentuates LUTS severity with insufficient evidence regarding the effectiveness and safety profile of the available therapeutic modalities. CONCLUSION: Understanding lifelong LUTSs offers insights into genetic, anatomical, neurological, and molecular mechanisms. Further research could identify predictive biomarkers, elucidate the role of clinically translatable elements in pelvic cross-talk, and uncover molecular signatures for personalized management.

INTRODUCTION: Overactive bladder (OAB) is a prevalent urological condition characterized by urinary urgency, with or without urgency urinary incontinence, accompanied by increased daytime frequency and nocturia. However, the current definition of OAB lacks a specified time frame, hindering our understanding of the temporal aspects and transitions that occur within the OAB spectrum. METHODS: A modified Delphi study was conducted in three rounds, involving a panel of international experts in functional urology, urogynaecology, geriatrics, transitional medicine, and pediatric urology. The study took place between February 2023 and June 2023 and employed two sequential rounds of online surveys, followed by a final hybrid group discussion session in June 2023. RESULTS: The Delphi process resulted in a consensus definition of lifelong OAB as a persistent and continuous condition that may manifest differently from birth and evolve over time, with varying levels of clinical perception. The course of its progression is influenced by transition periods and modifying factors, mainly anatomical, hormonal, and psychosocial/stressors. Three main transition periods were identified: achievement of daytime continence, adulthood to elderly, and transition to frail elderly. The panel also considered the therapeutic and diagnostic implications of lifelong OAB, as well as future research prospects in terms of importance and feasibility. CONCLUSIONS: Future longitudinal research is needed to develop this concept and further identify transitions and temporal dynamics.

BACKGROUND: Pudendal nerve entrapment (PNE) is an underdiagnosed condition affecting a spectrum of pelvic functions, primarily pain, as outlined by Nantes diagnostic criteria. Although numerous surgical decompression techniques are available for its management, consensus on efficacy and safety is lacking. This study conducts a systematic review and meta-analysis to assess the efficacy and complication rates of the main surgical decompression techniques. METHODS: A comprehensive literature search was conducted in PubMed®, Embase®, Web of Science®, and ClinicalTrails.gov® on 19th of April 2023. Initial screening involved title and abstract evaluation, with subsequent retrieval and assessment of abstracts and full-text articles. Studies assessing pain outcomes before and after surgical release of the pudendal nerve were included. Studies without full-text, focusing on diagnostic methods or with outcomes relating solely to LUTS, digestive symptoms, or sexual dysfunction, were excluded. Risk of bias assessement was conducted using the National Institute of Health (NIH) Study Quality Assessment tool. Studies were categorized based on three surgical techniques: perineal, transgluteal, and laparoscopic transperitoneal. Random-effects meta-analysis with subgroup analysis were used. Meta-regression analyses were conducted to investigate the influence of covariates on the observed outcomes. RESULTS: Nineteen studies, comprising 810 patients, were included. The overall significant pain relief rate across all techniques was estimated at 0.67 (95% CI 0.54 to 0.78) with considerable heterogeneity (I2 = 80.4%). Subgroup analysis revealed success rate for different techniques: laparoscopic (0.91, 95% CI 0.64 to 0.98), perineal (0.69, 95% CI 0.52 to 0.82), and transgluteal (0.50, 95% CI 0.37 to 0.63). The laparoscopic technique exhibited a complication rate of 16.0%. Meta-regression indicated that patient age and median follow-up significantly influenced outcomes. CONCLUSION: While comparing surgical techniques is challenging, this meta-analysis highlights important outcome differences. The laparoscopic technique appears most promising for pain improvement. However, the study also emphasizes the need for further robust, long-term research due to significant heterogeneity across studies and prevelent risk of bias. PROSPERO database: CRD42023496564.

INTRODUCTION AND HYPOTHESIS: The aim of this review is to discuss the link between menopause and nocturia and to give an overview of the increasing prevalence, risk factors, causative factors, treatment needs and options for nocturia in peri-menopausal women. METHODS: This opinion article is a narrative review based on the expertise and consensus of a variety of key opinion leaders, in combination with an extensive literature review. This literature search included a thorough analysis of potential publications on both the PubMed Database and the Web of Science and was conducted between November 2022 and December 2022. The following key words were used "nocturia" and "menopause" or "nocturnal frequency and menopause." Moreover, key words including "incidence," "prevalence," "insomnia," "estrogen therapy," "metabolic syndrome," and "hot flushes" were used in combination with the aforementioned key words. Last, the reference lists of articles obtained were screened for other relevant literature. RESULTS: The perimenopause can be a trigger for inducing nocturia. Typically, obesity, body mass index (BMI), and waist circumference are risk factors for developing peri-menopausal nocturia. Presumably the development of peri-menopausal nocturia is multifactorial, with interplay among bladder, sleep, and kidney problems due to estrogen depletion after the menopause. First, impaired stimulation of estrogen receptors in the urogenital region leads to vaginal atrophy and reduced bladder capacity. Moreover, menopause is associated with an increased incidence of overactive bladder syndrome. Second, estrogen deficiency can induce salt and water diuresis through blunted circadian rhythms for the secretion of antidiuretic hormone and the activation of the renin-angiotensin-aldosterone system. Additionally, an increased incidence of sleep disorders, including vasomotor symptoms and obstructive sleep apnea signs, is observed. Oral dryness and a consequent higher fluid intake are common peri-menopausal symptoms. Higher insulin resistance and a higher risk of cardiovascular diseases may provoke nocturia. Given the impact of nocturia on general health and quality of life, bothersome nocturia should be treated. Initially, behavioral therapy should be advised. If these modifications are inadequate, specific treatment should be proposed. Systemic hormone replacement is found to have a beneficial effect on nocturia, without influencing sodium and water clearance in patients with nocturnal polyuria. It is presumed that the improvement in nocturia from hormonal treatment is due to an improvement in sleep disorders.

OBJECTIVES: Sacral neuromodulation (SNM) has evolved as a therapeutic intervention for various pelvic floor dysfunctions. However, the traditional approach primarily assesses discipline-specific symptoms, potentially overlooking holistic symptom improvement. We aimed to investigate whether a more comprehensive evaluation of pelvic floor symptoms enhances the assessment of SNM's test phase. MATERIAL AND METHODS: A prospective single-center trial (Optimization of Lower Urinary Tract Symptoms study) assessed SNM efficacy from March 2018 to December 2021 in patients from the urology department (UD) and colorectal surgery department (CRD) with a follow-up of 12 months. Objective and subjective outcomes were examined using diaries and patient-reported outcome measures. Statistical analyses were conducted to determine predictive factors for treatment success, expressed by the patient global impression of change. SPSS 29.0 was used. RESULTS: A total of 85 participants were included, displaying concomitant pelvic floor symptoms. After the first phase, significant improvements on all pelvic floor domains questionnaires were seen for both patients from UD and those from CRD. Although improvements were observed in bladder and bowel diaries, the traditional criteria for success (≥50% improvement in diary variables) did not consistently correlate with the patients' global impression of change. The absolute reductions in bother sum scores from multiple domains were significant predictors for the patients' global impression of change, outperforming discipline-specific assessments. Patients from UD benefit from both a urologic and pelvic pain symptom evaluation, and those from CRD, from both a urologic and bowel symptom evaluation. CONCLUSIONS: SNM shows positive effects across various pelvic floor domains, even beyond the primary intended indication of implantation. The rather rigid approach of patient selection of discipline-specific symptoms alone can be questioned. A more comprehensive evaluation encompassing various pelvic floor symptoms with the emphasis on subjective outcome measures could enhance SNM's efficacy assessment during the test phase. CLINICAL TRIAL REGISTRATION: The Clinicaltrials.gov registration number for the study is NCT05313984.
RESUMEN
OBJECTIVE: To systematically review studies that investigated different biomarkers of nocturia, including omics-driven biomarkers or 'Nocturomics'. MATERIALS AND METHODS: PubMed® , Scopus® , and Embase® were searched systematically in May 2022 for research papers on biomarkers in physiological fluids and tissues from patients with nocturia. A distinction was made between biomarkers or candidates discovered by omics techniques, referred to as omics-driven biomarkers, and classical biomarkers, measured by standard laboratory techniques and mostly thought from pathophysiological hypothesis. RESULTS: A total of 13 studies with 18 881 patients in total were included, eight of which focused on classical biomarkers including: atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP), C-reactive protein (CRP), aldosterone, and melatonin. Five were 'Nocturomics', including one that assessed the microbiome and identified 27 faecal and eight urinary bacteria correlated with nocturia; and four studies that identified candidate metabolomic biomarkers, including fatty acid metabolites, serotonin, glycerol, lauric acid, thiaproline, and imidazolelactic acid among others. To date, no biomarker is recommended in clinical practice. Nocturomics are in an embryonic phase of conception but are developing quickly. Although candidate biomarkers are being identified, none of them are yet validated on a large sample, although some preclinical studies have shown a probable role of fatty acid metabolites as a possible biomarker of circadian rhythm and chronotherapy. CONCLUSION: Further research is needed to validate biomarkers for nocturia within the framework of a diagnostic and therapeutic precision medicine perspective. We hope this study provides a summary of the current biomarker discoveries associated with nocturia and details future prospects for omics-driven biomarkers.

PURPOSE: Female representation at scientific conferences is crucial for encouraging women pursuing an academic career. Nevertheless, gender inequity at urological conferences is common place and women are often stereotyped choosing functional urology. However, there is no evidence whether female representation is higher in functional urology. This investigations aims to analyze gender representation at functional urology sessions. METHODS: National and international urological congresses between 2019 and 2021 with a focus on functional urology and female urology sessions were evaluated. Congresses were categorized as national or international. Session type, topic, gender of chairs and speakers of the identified sessions were recorded. In addition, affiliation and medical specialty were collected for chairs. RESULTS: A total of 29 congresses were evaluated. Out of a total of 2893 chairs and speakers, 1034 (35.7%) were women and 1839 (63.6%) were men. This represents an overall gender gap of 27.9% for functional urology sessions. No significant differences in gender representation between national and international congresses could be identified (p = 0.076). When considering gender distribution of chairs, the gap was more pronounced by 35.5%. Furthermore, men were more likely to be invited to be a speaker in plenary and podiums sessions. CONCLUSIONS: Gender inequality is present in functional urology sessions. There is a need for greater efforts to achieve gender equality. An important step to remedy the situation is the inclusion of women in scientific program committees. Furthermore, support by the leadership of urological societies and academic departments is essential to herald a lasting change in gender inequality.

PURPOSE OF REVIEW: The aim of this narrative review is to evaluate the current available literature on urinary outcomes following cryotherapy and high-intensity focused ultrasound (HIFU) for localized prostate cancer (PCa). RECENT FINDINGS: The available literature is heterogeneous in terms of intervention modalities and assessment of urinary outcome measures. Nevertheless, ultra-minimally invasive treatments seem to provide good urinary outcomes. Technological advancement and the adoption of more conservative ablation templates allow for a further reduction of toxicity and better preservation of urinary function. Urinary incontinence occurs in 0-10% of the patients and, is mostly transient. Voiding and storage lower urinary tract symptoms (LUTS) mostly occur in the early postoperative period and rarely require surgical treatment. Focal therapies performed with a salvage intent after external beam radiotherapy have a significantly higher impact on patient's urinary function. SUMMARY: Ultra-minimally invasive treatment for PCa show a good safety profile concerning urinary function, but consensus on when and how best to assess this is still lacking. Efforts should be made to standardize the report of preoperative and postoperative urinary function to provide higher level of evidence.
RESUMEN
INTRODUCTION: Inflammation and neuronal hypersensitivity are reactive protective mechanisms after urothelial injury. In lower urinary tract dysfunctions (LUTD), such as urinary tract infection (UTI), bladder pain syndrome with interstitial cystitis (BPS/IC) and neurogenic LUTD after spinal cord injury (SCI), chronic inflammation can develop. It is unclear how the protective reactionary inflammation escalates into chronic disease in some patients. METHODS: During its 2023 meeting in Bristol, the International Consultation on Incontinence-Research Society (ICI-RS) reviewed the urothelial and inflammatory changes after UTI, BPS/IC and SCI. Potential factors contributing to the evolution into chronic disease were explored in a think-tank. RESULTS: Five topics were discussed. (1) Visceral fat metabolism participates in the systemic pro-inflammatory effect of noradrenalin in BPS/IC and SCI. Sympathetic nervous system-adipocyte-bladder crosstalk needs further investigation. (2) Sympathetic hyperactivity also potentiates immune depression in SCI and needs to be investigated in BPS/IC. Gabapentin and tumor necrosis factor-α are promising research targets. (3) The exact peripheral neurons involved in the integrative protective unit formed by nervous and immune systems need to be further identified. (4) Neurotransmitter changes in SCI and BPS/IC: Neurotransmitter crosstalk needs to be considered in identifying new therapeutic targets. (5) The change from eubiosis to dysbiosis in SCI can contribute to UTI susceptibility and needs to be unraveled. CONCLUSIONS: The think-tank discussed whether visceral fat metabolism, immune depression through sympathetic hyperactivity, peripheral nerves and neurotransmitter crosstalk, and the change in microbiome could provide explanations in the heterogenic development of chronic inflammation in LUTD. High-priority research questions were identified.
RESUMEN
AIMS: Lower urinary tract dysfunctions (LUTD) are very common and, importantly, affect patients' quality of life (QoL). LUTD can range from urinary retention to urgency incontinence and includes a variety of symptoms. Nerve stimulation (NS) is an accepted widespread treatment with documented success for LUTD and is used widely. The aim of this review is to report the results of the discussion about how to improve the outcomes of NS for LUTD treatment. METHODS: During its 2023 meeting in Bristol, the International Consultation on Incontinence Research Society discussed a literature review, and there was an expert consensus discussion focused on the emerging awareness of NS suitable for LUTD. RESULTS: The consensus discussed how to improve techniques and patients' selection in NS, and high-priority research questions were identified. CONCLUSIONS: Technique improvement, device programming, and patient selection are the goals of the current approach to NS. The conditional nerve stimulation with minimally invasive wireless systems and tailored algorithms hold promise for improving NS for LUTD, particularly for patients with neurogenic bladder who represent the new extended population to be treated.
RESUMEN
INTRODUCTION: This article delves into the intricate relationship between kidney function, diuresis, and lower urinary tract symptoms (LUTS) throughout the transitions of the human lifespan. It explores circadian regulation of urine production, maturation of renal function from birth to adulthood, and effects of aging on kidney function and LUTS. The complex connections between these factors are highlighted, offering insights into potential interventions and personalized management strategies. METHODS: An international panel of seven experts engaged in online discussions, focusing on kidney function, diuresis, and LUTS throughout life. This manuscript summarizes expert insights, literature reviews, and findings presented during a webinar and subsequent discussions. RESULTS: Renal function undergoes significant maturation from birth to adulthood, with changes in glomerular filtration rate, diuresis, and tubular function. A circadian rhythm in urine production is established during childhood. Adolescents and young adults can experience persistent enuresis due to lifestyle factors, comorbidities, and complex physiological changes. In older adults, age-related alterations in kidney function disrupt the circadian rhythm of diuresis, contributing to nocturnal polyuria and LUTS. CONCLUSION: The interplay between kidney function, diuresis, and LUTS is crucial in understanding lifelong urinary health. Bridging the gap between pediatric and adult care is essential to address enuresis in adolescents and young adults effectively. For older adults, recognizing the impact of aging on renal function and fluid balance is vital in managing nocturia. This holistic approach provides a foundation for developing innovative interventions and personalized treatments to enhance quality of life for individuals with LUTS across all stages of life.
RESUMEN
OBJECTIVE: In light of a better understanding of supraspinal control of nonneurogenic overactive bladder (OAB), the prevalence of which increases with age, functional imaging has gained significant momentum. The objective of this study was to perform a systematic review on the transition of supraspinal control of OAB with age, the effect of therapeutic modalities, and a coordinate-based meta-analysis of all neuroimaging evidence on supraspinal OAB control in response to bladder filling. METHODOLOGY: We performed a systematic literature search of all relevant libraries in November 2021. The coordinates of brain activity were extracted from eligible neuroimaging studies to perform an activation likelihood estimation (ALE) meta-analysis. RESULTS: A total of 16 studies out of 241 were selected for our systematic review. Coordinates were extracted from five experiments involving 70 patients. ALE meta-analysis showed activation of the insula, supplementary motor area, dorsolateral prefrontal cortex, anterior cingulate gyrus, and temporal gyrus with a transition of activation patterns with age, using a threshold of uncorrected p < 0.001. Among young patients, neuroplasticity allows the activation of accessory circuits to maintain continence, as in the cerebellum and temporoparietal lobes. Anticholinergics, pelvic floor muscle training, sacral neuromodulation, and hypnotherapy are correlated with supraspinal changes attributed to adaptability and possibly a substratum of an intrinsic supraspinal component. The latter is better demonstrated by a resting-state functional connectivity analysis, a promising tool to phenotype OAB with recent successful models of predicting severity and response to behavioral treatments. CONCLUSION: Future neuroimaging studies are necessary to better define an OAB neurosignature to allocate patients to successful treatments.

BACKGROUND: Many different internal factors have been proven to influence urine production such as age, weight, and quality of sleep. External factors such as consumption of caffeine and fluid consumption have been shown to have an impact on urine production. AIM: To investigate the impact of movement, physical activity and position on urine production. METHODS: This prospective observational study was executed at Ghent University Hospital, Belgium. Study participation was open for anyone visiting the hospital. Participants collected one basic and two extended 24-hour urine collections and filled in questionnaires concerning their general health and physical activity. Urinary levels of osmolality, sodium and creatinine were determined. Data on movement, physical activity and position was described. RESULTS: An increase in body movement leads to a significant increase in diuresis during daytime, night-time, and 24 hours (P = .002, P < .001, and P < .001, respectively). An increase in body movement leads to a significant decrease in osmolality during night-time and 24 hours (P = .009, and P = .004, respectively). However, no significant influence of movement on osmolality was found during daytime (P = .12). An increase in body movement leads to a significant decrease in creatinine during daytime, night-time and 24 hours (P = .001, <0.001, and P < .001, respectively). An increase in body movement leads to a significant increase in sodium during daytime (P = .046) but this was statistically significant during night-time and 24 hours (P = .32, and P = .84 respectively). CONCLUSION: Our study demonstrates a statistically significant association of movement, physical activity, and position with urine production. It would therefore be interesting to explore this association further with the use of new technology to have more accurate data. Here, lays a potential role for conservative measurements and lifestyle adaptations in the management of patients with bothersome LUTS and more precisely nocturia.

AIMS: Idiopathic overactive bladder syndrome (iOAB) is a prevalent condition in urological practice. The variability in management between specialists and between centers remains high. Even existing guidelines contain inconsistencies. We aimed to develop a treatment algorithm for iOAB for use in daily clinical practice. METHODS: From October 2018 till November 2019, a Delphi study was conducted to obtain expert consensus on the management of iOAB. Members from the Belgian Working Group of Functional Urology were asked to rate online statements, based on gaps and variabilities between the American Urology Association (AUA), European Association of Urology (EAU) and International Consultation on Incontinence (ICI) guidelines on iOAB. The consensus was reached if ≥75% of the panel agreed on the level of appropriateness. Two Delphi rounds and an open discussion session were held. RESULTS: Twenty out of 49 members completed the first round and 18 completed the second round. The consensus was reached on 44/143 statements and 15/56 statements in the first and second round, respectively. The consensus was reached on criteria by which to phenotype OAB patients, the terminology relating to the first-, second- and third-line treatment, the duration of therapies, the chronological order, and the choice between therapies. No consensus was reached on the role of percutaneous tibial nerve stimulation (PTNS) in the treatment algorithm. CONCLUSIONS: A flowchart reflecting the current attitude and approach of a Delphi expert panel towards the treatment of iOAB was developed. We propose its use in daily clinical practice to increase the standardization of OAB treatment.

AIMS: Chronic urinary retention occurring in young women is poorly understood and a cause may not be found in a majority of cases. Different psychological comorbidities and functional neurological symptom disorders (FNDs) have been reported; however, these have been poorly explored. METHODS: At the International Consultation on Incontinence Research Society meeting in 2019, a panel of clinicians generated a proposal to explore the relationship between psychological comorbidities, FNDs, and urinary retention in women with chronic idiopathic urinary retention. RESULTS: Psychological comorbidities such as depression and anxiety, and FNDs such as leg weakness and loss of consciousness, have been reported in women with idiopathic urinary retention. Individuals react differently to physical and emotional stressors, and experimental models have demonstrated a relationship between the stress response and developing urinary retention. Trauma, particularly sexual trauma, may be a shared risk factor for developing psychological comorbidities and urinary retention. Children with voiding postponement often suffer from psychological comorbidities and behavioral disturbances; however, there is no evidence to suggest that this progresses to urinary retention in adulthood. "Psychogenic urinary retention" has been described in the urology and psychiatry literature in the past, and anecdotal cases of successful voiding following psychotherapy have been reported, though the true pathophysiology of this entity is uncertain. CONCLUSION: Psychological and functional disorder comorbidities are reported in women with chronic urinary retention. The nature of the association between urinary retention and functional neurological disorder comorbidities needs to be further explored in terms of a disorder of bladder-brain interaction.
