RESUMO
PURPOSE: Transcutaneous spinal cord stimulation (TSCS) is a novel neuromodulation modality developed to promote functional restoration in patients with neurological injury or disease. Previous pilot data suggest that lower urinary tract dysfunction (LUTD) due to stroke may be partially alleviated by TSCS. In this study, we examine the mechanism of this effect by evaluating bladder-related brain activity in patients before and after TSCS therapy and comparing it to healthy volunteers. MATERIALS AND METHODS: Patients who developed storage LUTD after a stroke and healthy volunteers without LUTD were recruited. Patients and healthy volunteers underwent simultaneous urodynamics and functional MRI. Patients then completed 24 biweekly sessions of TSCS and underwent another simultaneous urodynamics-functional MRI study. Clinical outcomes were assessed using validated questionnaires and voiding diary. RESULTS: Fifteen patients and 16 healthy volunteers completed the study. Following TSCS, patients exhibited increased blood-oxygen-level-dependent activity in areas including periaqueductal grey, the insula, the lateral prefrontal cortex, and motor cortex. Prior to TSCS therapy, healthy controls exhibited higher blood-oxygen-level-dependent activity in 17 regions, including multiple regions in the prefrontal cortex and basal ganglia. These differences were attenuated after TSCS with no frontal brain differences remaining between healthy volunteers and stroke participants who completed therapy. Neuroimaging changes were complemented by clinically significant improvements in questionnaire scores and voiding diary parameters. CONCLUSIONS: TSCS therapy modulated bladder-related brain activity, reducing differences between healthy volunteers and stroke patients with LUTD. These changes, alongside improved clinical outcomes, suggest TSCS as a promising approach for LUTD management.

PURPOSE: The purpose of this guideline is to provide evidence-based guidance to clinicians of all specialties on the evaluation, management, and treatment of idiopathic overactive bladder (OAB). The guideline informs the reader on valid diagnostic processes and provides an approach to selecting treatment options for patients with OAB through the shared decision-making process, which will maximize symptom control and quality of life, while minimizing adverse events and burden of disease. METHODS: An electronic search employing OVID was used to systematically search the MEDLINE and EMBASE databases, as well as the Cochrane Library, for systematic reviews and primary studies evaluating diagnosis and treatment of OAB from January 2013 to November 2023. Criteria for inclusion and exclusion of studies were based on the Key Questions and the populations, interventions, comparators, outcomes, timing, types of studies and settings (PICOTS) of interest. Following the study selection process, 159 studies were included and were used to inform evidence-based recommendation statements. RESULTS: This guideline produced 33 statements that cover the evaluation and diagnosis of the patient with symptoms suggestive of OAB; the treatment options for patients with OAB, including non-invasive therapies, pharmacotherapy, minimally invasive therapies, invasive therapies, and indwelling catheters; and the management of patients with BPH and OAB. CONCLUSION: Once the diagnosis of OAB is made, the clinician and the patient with OAB have a variety of treatment options to choose from and should, through shared decision-making, formulate a personalized treatment approach taking into account evidence-based recommendations as well as patient values and preferences.

PURPOSE: To report perioperative and long-term postoperative outcomes of cystectomy patients with ileal conduit (IC) urinary diversion undergoing parastomal hernia (PSH) repair. METHOD: We reviewed patients who underwent cystectomy and IC diversion between 2003 and 2022 in our center. Baseline variables, including surgical approach of PSH repair and repair technique, were captured. Multivariable Cox regressionanalysis was performed to test for the associations between different variables and PSH recurrence. RESULTS: Thirty-six patients with a median (IQR) age of 79 (73-82) years were included. The median time between cystectomy and PSH repair was 30 (14-49) months. Most PSH repairs (32/36, 89%) were performed electively, while 4 were due to small bowel obstruction. Hernia repairs were performed through open (n=25), robotic (10), and laparoscopic approaches (1). Surgical techniques included direct repair with mesh (20), direct repair without mesh (4), stoma relocation with mesh (5), and stomarelocation without mesh (7). The 90-day complication rate was 28%. In a median follow-up of 24 (7-47) months, 17 patients (47%) had a recurrence. The median time to recurrence was 9 (7-24) months. On multivariable analysis, 90-day complication following PSH repair was associated with an increased risk of recurrence. CONCLUSIONS: In this report of one of the largest series of PSH repair in the Urology literature, 47% of patients had a recurrence following hernia repair with a median follow-up time of 2 years. There was no significant difference in recurrence rates when comparing repair technique or the use of open or minimally invasive approaches.

INTRODUCTION AND OBJECTIVES: Relevant, meaningful, and achievable data points are critical in objectively assessing quality, utility, and outcomes in female stress urinary incontinence (SUI) surgery. A minimum data set female SUI surgery studies was proposed by the first American Urological Association guidelines on the surgical management of female SUI in 1997, but recommendation adherence has been suboptimal. The Female Stress Urinary Incontinence Surgical Publication Working Group (WG) was created from members of several prominent organizations to formulate a recommended standard of study structure, description, and minimum outcome data set to be utilized in designing and publishing future SUI studies. The goal of this WG was to create a body of evidence better able to assess the outcomes of female SUI surgery. METHODS: The WG reviewed the minimum data set proposed in the 1997 AUA SUI Guideline document, and other relevant literature. The body of literature was examined in the context of the profound changes in the field over the past 25 years. Through a DELPHI process, a standard study structure and minimum data set were generated. Care was taken to balance the value of several meaningful and relevant data points against the burden of creating an excessively difficult or restrictive standard that would disincentivize widespread adoption and negatively impact manuscript production and acceptance. RESULTS: The WG outlined standardization in four major areas: (1) study design, (2) pretreatment demographics and characterization of the study population, (3) intraoperative events, and (4) posttreatment evaluation, and complications. Forty-two items were evaluated and graded as: STANDARD-must be included; ADDITIONAL-may be included for a specific study and is inclusive of the Standard items; OPTIMAL-may be included for a comprehensive study and is inclusive of the Standard and Additional items; UNNECESSARY/LEGACY-not relevant. CONCLUSIONS: A reasonable, achievable, and clinically meaningful minimum data set has been constructed. A structured framework will allow future surgical interventions for female SUI to be objectively scrutinized and compared in a clinically significant manner. Ultimately, such a data set, if adopted by the academic community, will enhance the quality of the scientific literature, and ultimately improve short and long-term outcomes for female patients undergoing surgery to correct SUI.

RESUMO
INTRODUCTION: Neurogenic bowel dysfunction is commonly encountered after a spinal cord injury (SCI), leading to a tremendous impact on quality of life (QOL). The neurogenic bowel dysfunction score (NBDS) is commonly used to measure the severity of bowel dysfunction and predict QOL. However, there is no comprehensive instrument to assess bowel-specific QOL for SCI patients. Instead, the Irritable Bowel Syndrome-Quality of Life (IBS-QOL) questionnaire evaluates the impact of bowel dysfunction on several aspects of QOL, although this questionnaire has not been validated for the SCI population. Motivated by the compelling need of instruments to accurately evaluate the QOL in patients who develope NBD after SCI, we aimed to assess the construct, content, and face validity of IBS-QOL in this population. METHODS: Adult SCI patients with at least 3 months after their injury were recruited from the outpatient clinic of a national rehabilitation hospital. Patients completed the NBDS and IBS-QOL via telephone interview or paper survey in the clinic. Content and face validity were assessed via interviews with professionals with expertise in providing chronic care for SCI, as well as a subgroup of patients. Construct validity was assessed using the hypotheses testing method. Internal consistency was assessed using Cronbach's âº. Factor analysis was performed to assess the dimensionality of the IBS-QOL in the SCI population. RESULTS: A total of 106 patients with a median age of 45.5 years (interquartile range: 21-79) participated in the study. The majority of the sample were men (n = 82, 77%) and had endured thoracolumbar injuries (n = 74, 71.2%). Twelve patients (seven English- and five Spanish speakers) and six professionals took part in content/face validation interviews. The median IBS-QOL total score was 15.91/100 (interquartile range: 4.55-33.14). IBS-QOL differentiated the subgroups of patients with severe bowel symptoms in terms of uneasiness, sweating, or headaches during bowel emptying (p = 0.0003), time spent on bowel emptying (p = 0.0065), flatus incontinence (p = 0.0076), and overall satisfaction with bowel function (p < 0.001), demonstrating its adequate construct validity. Interviews with the patients and professionals supported the comprehensiveness, comprehensibility, and relevance of IBS-QOL for assessment of bowel-related QOL in the SCI population. Item-level analysis of professional responses showed that 97% of questions were relevant to the construct and population of interest. Internal consistency analysis yielded a Cronbach's ⺠of 0.9684. Exploratory factor analysis yielded six underlying factors which cumulatively accounted for 72.21% of the total variance, reflecting the dimensionality of bowel-related QOL in SCI population. DISCUSSION: IBS-QOL questionnaire is a comprehensive measure of bowel-related QOL which encompasses the concerns of SCI patients. Our findings support the content, face and construct validity of IBS-QOL as a measure of bowel-related QOL in SCI. Further studies are warranted to assess the reliability and responsiveness of IBS-QOL, and to evaluate its performance across different patient populations.

PURPOSE: The clinical, social, and economic impacts of neurogenic lower urinary tract dysfunction (NLUTD) on individuals and health care systems are thought to be immense, yet the true costs of care are unknown. The aims of this study are to illuminate the global costs related to the current state of care for NLUTD. MATERIALS AND METHODS: A systematic review of the literature was performed using MEDLINE, the National Health Service Economic Evaluation Database, and the Cochrane Specialized Urology and Incontinence Registers. Studies reporting the health care costs of NLUTD were identified. All steps of the review were performed by 2 independent reviewers. Costs were converted to 2022 U.S. dollars and reported for different categories of services. RESULTS: A total of 13 studies were included in the final review (12 from high-income economy, and 1 from an upper-middle-income economy). Routine maintenance care varied notably across studies in terms of included services. Annual supportive costs ranged from $2,039.69 to $12,219.07 with 1 study estimating lifetime costs of $112,774 when complications were considered. There were limited data on the costs of care from the patient's perspective. However, catheters and absorbent aids were estimated to be among the costliest categories of expenditure during routine care. More invasive and reconstructive treatments were associated with significant costs, ranging between $18,057 and $55,873. CONCLUSIONS: NLUTD incurs a variety of health care expenditures ranging from incontinence supplies to hospitalizations for management of complications and leads to a significant burden for health care systems over the patient's lifetime. Approaches to NLUTD that focus on functional rehabilitation and restoration, rather than on management of complications, may prove to be a less costly and more effective alternative.

PURPOSE: Neurogenic lower urinary tract dysfunction is a significant source of morbidity for individuals with spinal cord injury and is managed with a range of treatment options that differ in efficacy, tolerability and cost. The effect of insurance coverage on bladder management, symptoms and quality of life is not known. We hypothesized that private insurance is associated with fewer bladder symptoms and better quality of life. MATERIALS AND METHODS: This is a cross-sectional, retrospective analysis of 1,226 surveys collected as part of the prospective Neurogenic Bladder Research Group SCI Registry. We included patients with complete insurance information, which was classified as private or public insurance. The relationship between insurance and bladder management, bladder symptoms and quality of life was modeled using multinomial logistic regression analysis. Spinal cord injury quality of life was measured by the Neurogenic Bladder Symptom Score. RESULTS: We identified 654 privately insured and 572 publicly insured individuals. The demographics of these groups differed by race, education, prevalence of chronic pain and bladder management. Publicly insured patients were more likely to be treated with indwelling catheters or spontaneous voiding and less likely to take bladder medication compared to those with private insurance. On multivariate analysis insurance type was not associated with differences in bladder symptoms (total Neurogenic Bladder Symptom Score) or in urinary quality of life. CONCLUSIONS: There is an association between insurance coverage and the type of bladder management used following spinal cord injury, as publicly insured patients are more likely to be treated with indwelling catheters. However, insurance status, controlling for bladder management, did not impact bladder symptoms or quality of life.

PURPOSE: The clinician treating patients with neurogenic lower urinary tract dysfunction (NLUTD) needs to balance a variety of factors when making treatment decisions. In addition to the patient's urologic symptoms and urodynamic findings, other issues that may influence management options of the lower urinary tract include cognition, hand function, type of neurologic disease, mobility, bowel function/management, and social and caregiver support. This Guideline allows the clinician to understand the options available to treat patients, understand the findings that can be seen in NLUTD, and appreciate which options are best for each individual patient. This allows for decisions to be made with the patient, in a shared decision-making manner, such that the patient's quality of life can be optimized with respect to their bladder management. MATERIALS AND METHODS: A comprehensive search for studies assessing patients undergoing evaluation, surveillance, management, or follow-up for NLUTD was conducted from January 2001 through October 2017 and was rerun in February 2021 to capture newer literature. The primary search returned 20,496 unique citations. Following a title and abstract screen, full texts were obtained for 3,036 studies. During full-text review, studies were primarily excluded for not meeting the PICO criteria. One hundred eight-four primary literature studies met the inclusion criteria and were included in the evidence base. RESULTS: This guideline was developed to inform clinicians on the proper evaluation, diagnosis, and risk stratification of adult patients with NLUTD and the non-surgical and surgical treatment options available. Additional statements on urinary tract infection and autonomic dysreflexia were developed to guide the clinician. CONCLUSIONS: NLUTD patients may undergo non-surgical and surgical treatment options depending on their level of risk, symptoms, and urodynamic findings. Appropriate follow-up, primarily based on their risk stratification, must be maintained after treatment.

After diagnosis and stratification, patients should be monitored according to their level of risk at regular intervals. Patients who experience new or worsening signs and symptoms should be reevaluated and risk stratification should be repeated.

OBJECTIVE: Cerebral stroke is a unique model for studying the role of the brain in lower urinary tract (LUT) control. By its nature, stroke must change the activity of the brain to cause LUT dysfunction. The objective of this study was to describe changes in micturition-related brain activity in patients who develop LUT symptoms (LUTS) after a cerebral stroke. MATERIALS AND METHODS: Healthy controls (HC, n = 10) and patients who developed storage LUTS after a cerebral stroke (n = 7) were recruited. Functional magnetic resonance imaging was used to assess brain activity in each subject. In the task-based block design, blood-oxygen-level-dependent (BOLD) signal was detected during rest, active bladder filling, and bladder voiding. BOLD signal intensity was compared between HCs and stroke subjects during bladder filling, voiding, and voiding initiation. RESULTS: Stroke subjects exhibited higher activity in the periaqueductal gray and cerebellum during bladder filling and bladder voiding. HCs exhibited more intense activity in higher centers, such as the cingulate cortex, motor cortex, and the dorsolateral prefrontal cortex in each of the phases examined. CONCLUSIONS: Subjects with stroke-related LUTS exhibit a specific pattern of brain activity during bladder filling and voiding. There appears to be a greater reliance on primitive centers (cerebellum, midbrain) than in healthy controls during both phases of the micturition cycle. We hypothesize that these findings may reflect loss of connectivity with higher brain centers after a stroke.

AIM: Interstitial cystitis/painful bladder syndrome/(IC/PBS) results in recurring pain in the bladder and surrounding pelvic region caused by abnormal excitability of micturition reflexes. Spinal cord stimulation (SCS) is currently clinically used for the attenuation of neuropathic and visceral pain. The present study examined whether SCS at upper lumbar segments modulates detrusor overactivity and visceral hyperalgesia associated with cystitis in a rat model of cyclophosphamide (CYP)-induced cystitis. METHODS: Cystitis was induced by intraperitoneal injection of CYP (200 mg/kg) in six adult female Sprague Dawley rats 48 h prior to urodynamic recordings. Another six rats served as-controls with saline injection. Cystometry and the external urethral sphincter (EUS) electromyography during bladder infusion were evaluated under urethane anesthesia. The visceromotor reflexes (VMR) obtained from the external abdominal oblique muscle were quantified during bladder infusion and isotonic bladder distension (IBD), respectively. After baseline recordings were taken, SCS was applied on the dorsal surface of L3 for 25 min. Urodynamic recordings and VMR during bladder infusion and IBD were repeated 2 h after SCS. RESULTS: CYP resulted in detrusor overactivity, stronger EUS tonic contractions, and increased VMR. SCS significantly reduced non-voiding contractions, prolonged EUS relaxation, and delayed VMR appearance during bladder infusion as well as significantly decreased VMR during IBD in cystitis rats. CONCLUSION: SCS improved bladder function and EUS relaxation during bladder infusion and significantly attenuated visceral nociceptive-related VMR during IBD in cystitis rats. SCS may have therapeutic potential for patients with hyperalgesia and IC/PBS.

AIM: We report the rates of artificial urinary sphincter (AUS) mechanical failure in a contemporary cohort of patients stratified by component type and size to determine if the 3.5-cm cuff is at higher risk of failure. METHODS: From 2005-2016, a total of 486 male patients with stress incontinence underwent implantation or revision of an AUS. 993 individual cases were retrospectively reviewed (465 primary placements and 528 revisions). Components were separately tallied and cases of mechanical failure were identified. Multiple variables including duration until failure and follow-up interval were collected and analyzed for each malfunction. RESULTS: After median follow-up of 31.5 months, there were 48 distinct cases of mechanical failure. The urethral cuff was the most common component to fail (n = 27, 56.3%), followed by the pressure regulating balloon (PRB) (n = 6, 12.5%), tubing (n = 6, 12.5%), and the control pump, (n = 5, 10.4%). Four (8.3%) cases did not have the source of malfunction identifiable in available records though fluid loss was evident at the time of device interrogation. Sub-analyses of cuff failure events showed that the 3.5-cm cuff had a statistically significant higher risk of failure (HR: 7.313, (P < .0001) compared to larger cuff sizes. CONCLUSIONS: While each component is prone to malfunction, our study suggests that the 3.5-cm urethral cuff is more susceptible to failure and failure events occur earlier after placement than larger cuff sizes.

PURPOSE OF REVIEW: The goal of this study is to delineate the role of advanced urologic evaluation with urodynamics prior to renal transplantation. We seek to report on its indications, possible findings, and subsequent treatment pathways. RECENT FINDINGS: This body of literature is largely comprised of retrospective, single-site studies. Patient selection for urodynamics can be determined based on patient history and voiding symptoms. Many of these renal transplant patients have urodynamic abnormalities such as decreased bladder capacity and compliance. Appropriate treatment of these abnormalities allows for average rates of graft survival. Urodynamic evaluation is not needed in every renal transplant recipient. However, in patients with oliguria or bladder dysfunction, urodynamics can often reveal significant pathology. The well-selected patient with lower urinary tract symptoms may also benefit from urodynamic evaluation. Treatment options are widely variable, from observation to reconstructive surgery, and should be based on the patient and urodynamic findings.

PURPOSE: Neurogenic bladder due to spinal cord injury has significant consequences for patients' health and quality of life. Regular surveillance is required to assess the status of the upper and lower urinary lower urinary tracts and prevent their deterioration. In this review, we examine surveillance techniques in neurogenic bladder, describe common complications of this disease, and address strategies for their management. METHODS: This work represents the efforts of SIU-ICUD joint consultation on Urologic Management of the Spinal Cord injury. For this specific topic, a workgroup was formed and comprehensive literature search of English language manuscripts regarding neurogenic bladder management was performed using key words of neurogenic bladder. Articles were compiled, and recommendations in the chapter are based on group discussion and follow the Oxford Centre for Evidence-based Medicine system for Levels of Evidence (LOEs) and Grades of Recommendation (GORs). RESULTS: At a minimum, patients should undergo an annual history and physical examination, renal functional testing (e.g., serum creatinine), and upper tract imaging (e.g., renal ultrasonography). The existing evidence does not support the use of other modalities, such as cystoscopy or urodynamics, for routine surveillance. Urologic complications in neurogenic bladder patients are common and often more complex than in the general population. CONCLUSIONS: There is a shortage of high-quality evidence to support any particular neurogenic bladder surveillance protocol. However, there is consensus regarding certain aspects of regular genitourinary system evaluation in these patients. Proper surveillance allows the clinician to avoid or address common urological complications, and to guide, alter, or maintain appropriate therapeutic regimens for individual patients.
