RESUMO
PURPOSE: To examine the accuracy of cystography under general anesthesia in children with vesicoureteral reflux (VUR). MATERIALS AND METHODS: A prospective study of children who had VUR on cystography without general anesthesia (i.e., the gold-standard), and who are candidates for endoscopic VUR repair surgery. All children subsequently underwent a cystography under general anesthesia before injection using standardized method, which was compared to the gold-standard cystography. χ2 and Mann-Whitney U tests were used to compare proportions and medians between groups. RESULTS: Between 2017 and 2021, 126 renal units in 13 boys and 50 girls were included. Median age was 3.4 years (interquartile range [IQR] 1.5-6.5). Median time from cystography without to cystography with general anesthesia was 3.8 months (IQR 2.7-6). Of the 126 renal units, 96 had VUR on cystography without general anesthesia. On dichotomous analysis (no VUR vs. any VUR) sensitivity, specificity, negative and positive predictive values of cystography under general anesthesia were 47% (45/96), 87% (26/30), 34% (26/77) and 92% (45/49), respectively. Accuracy was 56.3%; Cohen's Kappa coefficient was 0.22, indicating poor agreement. In subgroup analysis, the sensitivity of cystography under general anesthesia was significantly lower in primary VUR (20% vs. 55% in secondary VUR, p = 0.01) and active VUR (14% vs. 52% in passive VUR, p = 0.008). CONCLUSION: Cystography under general anesthesia was poorly correlated to cystography performed while the child was awake or lightly sedated. Clinical decision relying on this cystography is questionable.

PURPOSE: We identified a subset of patients with noninfectious cystitis who develop refractory symptoms marked by diffuse inflammatory changes, reduced bladder capacity, and vesicoureteral reflux (VUR), termed here as "progressive inflammatory cystitis" (PIC). Our objective was to describe the phenotype, disease outcomes, and pathologic findings of PIC. MATERIAL AND METHODS: A single institution retrospective cohort study of patients with PIC. Patients with a history of pelvic radiation, urologic malignancy, or neurogenic bladder were excluded. We describe cohort characteristics and use bivariate analyses to compare subgroups. Kaplan-Meier methods estimate time to urinary diversion. RESULTS: From 2008 to 2020, 46 patients with PIC were identified. The median age of symptom onset was 63 years old (interquartile range [IQR]: 56, 70) and the most common presenting symptoms were urinary urgency/frequency (54%) and incontinence (48%). Urodynamics showed a median maximum bladder capacity of 80 mL (IQR: 34, 152), commonly with VUR (68%) and hydronephrosis (59%). Ultimately 36 patients (78%) underwent urinary diversion at a median of 4.5 years (IQR: 2, 6.5) after symptom onset. Significant pathologic findings include presence of ulceration (52%), acute and chronic inflammation (68%), including eosinophils (80%), lymphoid follicles (56%), and mast cells in both lamina and muscularis propria (76%). CONCLUSIONS: PIC is a newly defined entity characterized by significantly diminished bladder capacity, upper tract changes, and relatively quick progression to urinary diversion. Larger prospective cohort studies are required to further characterize this severe phenotype of chronic noninfectious cystitis, aid earlier diagnosis, and guide management decisions.

Urinary retention describes the inability to urinate. Based on the symptoms and the amount of the initial residual urine formation, a differentiation can be made between acute and chronic forms. The cause can be a subvesical obstruction or a bladder atony. In addition to emergency treatment in the form of initial relief of the strain on the bladder by insertion of a catheter, the indication for a definitive treatment with a clarification of the question whether an acute or chronic event is present is also important. Although the selection of the catheter is subject to few criteria, the further structured approach is complex. Both decision trees are presented in this article.

AIMS: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) causes long-standing pain and/or storage symptoms. This study aimed to evaluate the likelihood of deterioration of bladder sensation in a carrageenan-induced CP/CPPS model by direct measurement of the bladder mechanosensitive single-unit afferent nerve activity. METHODS: In this study, male adult Sprague-Dawley rats were used. They were injected 50 µL of 3% λ-carrageenan or its vehicle (saline) into both lobes of the ventral prostate. Seven days following injection, the pain behavior at the pelvic-perineal area (using von Frey filaments), prostatic blood flow (using a laser blood flowmeter), and histology were examined along with cystometry (under conscious free-moving condition) and mechanosensitive single-unit afferent nerve activity (under urethane anesthesia). RESULTS: The prostate showed increased tissue weight and decreased blood flow and inflammatory cell infiltration in the carrageenan group compared to the control group. Consequently, the threshold of the pain behavior was decreased, and the basal and threshold pressures of the bladder were increased in the carrageenan group. In contrast, no significant differences of bladder histology and other cystometric parameters were found between the groups. Regarding Aδ- or C-fibers, the mechanosensitive afferent nerve activities revealed no differences in either group. CONCLUSIONS: The carrageenan-induced CP/CPPS rat model showed edema, ischemia, and inflammatory pain in the prostate, whereas a little change was detected in bladder sensation. These findings, which were evaluated using a direct measurement of the mechanosensitive single-unit afferent nerve activity, suggest that the bladder sensation is unlikely deteriorated in this model.

PURPOSE: Ureteral complications following renal transplantation are more common in children than in adults. We identify potential risk factors for ureteral complications in pediatric patients. MATERIALS AND METHODS: We retrospectively studied a cohort of patients who underwent renal transplantation at Lurie Children's Hospital between 2004 and 2016. We analyzed the associations between patient characteristics, operative factors, graft characteristics and postoperative complications. RESULTS: A total of 224 renal transplantations in 219 patients were identified. Preexisting bladder pathology was present in 25% of cases. Overall rate of ureteral complications was 16%, with symptomatic vesicoureteral reflux being the most common. Ureteral complications were seen significantly more frequently in patients with underlying bladder pathology (26% vs 12%, p = 0.01). Rate of postoperative vesicoureteral reflux in patients with bladder pathology was lower when a urologist performed the reimplantation but the difference was not statistically significant (15% vs 27%, p = 0.35). Urologists were significantly more likely to perform the ureteral anastomosis in patients on clean intermittent catheterization (85% vs 43%, p = 0.004) and in patients with a history of complex bladder reconstruction (75% vs 28%, p <0.001). CONCLUSIONS: Patients with existing bladder pathology are at increased risk for ureteral complications, particularly vesicoureteral reflux. Since pediatric urologists routinely perform ureteral reimplantation in patients with existing bladder pathology, these patients may benefit from a multidisciplinary approach between urology and transplant surgery at renal transplantation.

AIMS: The primary aim is to explore the adherence predicting factors in clean intermittent self-catheterization (CISC) in patients aged over 65 years. The secondary aim is to assess whether in this population, the non-adherence risk is greater, compared with patients under 65. METHODS: All patients older than 65 that successfully learned CISC between January 2011 and January 2016 were included. A control population younger than 65 matched with sex, body mass index, and pathology was selected. RESULTS: One hundered and thirteen (66.9%) out of the 169 patients older than 65 included were adherent at 1 month, and 80 (47.3%) at 6-12 months. Obesity (P = 0.027), a low PP test (Pencil and Paper test) score (P = 0.037), significant urinary stress incontinence (SUI) (P = 0.048), and prescription of CISC less than three per day (P = 0.03) were the risk factors predicting stopping CISC at 1 month, but none was associated with non-adherence at 6-12 months. Compared with the younger group, age was a risk factor for poor adherence at 1 month. CONCLUSION: Obesity, low PP test score, and important SUI are factors of poor adherence to CISC at 1 month in older adults. Necessity of more than three CISC per day is in favor of treatment continuation, possibly due to absence of spontaneous voiding in these patients. Long-term adherence to CISC in older adults in this study remains close to adherence to other treatments prescribed in urinary disorders, and thus shows that CISC could be an easily purposed therapeutic option in this population, either on a long-term or transitory basis.

AIMS: Transient receptor potential melastatin 8 (TRPM8) is proposed to be a promising therapeutic target for hypersensitive bladder disorders. We examined the effects of KPR-2579, a novel selective TRPM8 antagonist, on body temperature and on mechanosensitive bladder single-unit afferent activities (SAAs) provoked by intravesical acetic acid (AA) instillation in rats. METHODS: Female Sprague-Dawley rats were used. Effects of cumulative intravenous (i.v.) administrations of KPR-2579 (0.03-1 mg/kg) on deep body temperature were investigated (N = 18). In separate animals, effects of bolus administration of KPR-2579 (0.03 or 0.3 mg/kg, i.v.) on bladder hyperactivity induced by intravesical instillation of 0.1% AA were investigated using cystometry (N = 57) in a conscious free-moving condition or urethane-anesthetized condition, and SAA measurements (N = 41) were performed in a urethane-anesthetized condition. RESULTS: KPR-2579 at any doses tested did not affect body temperature. In cystometry measurements, a high dose (0.3 mg/kg) of KPR-2579 counteracted the shortened intercontraction interval provoked by AA instillation. In SAA measurements, 48 single afferent fibers (n = 24 in each fiber) were isolated. AA instillations significantly increased the SAAs of C fibers, but not of Aδ fibers, in the presence of KPR-2579's vehicle and a low dose (0.03 mg/kg) of KPR-2579. Pretreatment with a high dose (0.3 mg/kg) of KPR-2579 significantly inhibited the AA-induced activation of C-fiber SAAs. CONCLUSION: The present results suggest that TRPM8 channels play a role in the AA-induced pathological activation of mechanosensitive bladder C fibers in rats. KRP-2579 may be a promising drug for hypersensitive bladder disorders.

BACKGROUND: During embryonal period, complete obliteration of the urachus at the umbilicus and incomplete closure at the bladder level are the cause of vesicourachal diverticulum. This abnormality is a rare finding that is usually discovered incidentally during radiological evaluation. Occasionally, stones have been detected within the diverticulum. CASE REPORT: We present a case of a vesicourachal diverticulum with calculus diagnosed by multidetector computed tomography and confirmed surgically and histopathologically in a 24-year-old man. CONCLUSIONS: During the radiological differential diagnosis of abnormalities of abdominal wall and urinary system, consideration of urachal abnormalities is important especially in symptomatic patients.
RESUMO
PURPOSE: The purpose of this amendment is to provide an updated clinical framework for the diagnosis and treatment of interstitial cystitis/bladder pain syndrome based upon data received since the publication of original guideline in 2011. MATERIALS AND METHODS: A systematic literature review using the MEDLINE(®) database (search dates 1/1/83-7/22/09) was conducted to identify peer-reviewed publications relevant to the diagnosis and treatment of IC/BPS. This initial review yielded an evidence base of 86 treatment articles after application of inclusion/exclusion criteria. The AUA update literature review process, in which an additional systematic review is conducted periodically to maintain guideline currency with newly published relevant literature, was conducted in July 2013. This review identified an additional 31 articles, which were added to the evidence base of this Guideline. RESULTS: Newly incorporated literature describing the treatment of IC/BPS was integrated into the Guideline with additional treatment information provided as Clinical Principles and Expert Opinions when insufficient evidence existed. The diagnostic portion of the Guideline remains unchanged from the original publication and is still based on Expert Opinions and Clinical Principles. CONCLUSIONS: The management of IC/BPS continues to evolve as can be seen by an expanding literature on the topic. This document constitutes a clinical strategy and is not intended to be interpreted rigidly. The most effective approach for a particular patient is best determined by the individual clinician and patient. As the science relevant to IC/BPS evolves and improves, the strategies presented will require amendment to remain consistent with the highest standards of care.

AIMS: To assess the urodynamic effects of soluble guanylyl cyclase (sGC) stimulator, BAY 41-2272, and activator, BAY 60-2770, (which both are able to induce cGMP synthesis even in the absence of nitric oxide (NO)) alone or in combination with a phosphodiesterase type 5 (PDE5) inhibitor, vardenafil, in a model of partial urethral obstruction (PUO) induced bladder overactivity (BO). METHODS: Fifty-six male Sprague-Dawley rats were used, 31 of them underwent PUO. Fourteen rats were used for Western blots to assess PDE5 and sGC expression. For drug evaluation cystometry without anesthesia was performed three days following bladder catheterization. RESULTS: Obstructed rats showed higher micturition frequency and bladder pressures than non-obstructed animals (Intermicturition Interval, IMI, 2.28 ± 0.55 vs. 3.60 ± 0.60 min (± standard deviation, SD); maximum micturition pressure, MMP, 70.1 ± 8.0 vs. 48.8 ± 7.2 cmH2O; both P < 0.05). In obstructed rats vardenafil, BAY 41-2272, and BAY 60-2770 increased IMI (2.77 ± 1.12, 2.62 ± 0.52, and 3.22 ± 1.04 min; all P < 0.05) and decreased MMP (54.4 ± 2.8, 61.5 ± 11.3, and 51.2 ± 6.3 cmH2O; all P < 0.05). When vardenafil was given following BAY 41-2272 or BAY 60-2770 no further urodynamic effects were observed. PDE5 as well as sGC protein expression was reduced in obstructed bladder tissue. CONCLUSIONS: Targeting sGC via stimulators or activators, which increase the levels of cGMP independent of endogenous NO, is as effective as vardenafil to reduce urodynamic signs of BO. Targeting the NO/cGMP pathway via compounds acting on sGC might become a new approach to treat BO.

BACKGROUND: Lower urinary tract symptoms (LUTS) in older men are associated with an increased risk of mobility limitations. Lower extremity muscle quality may represent a novel shared mechanism of both LUTS and mobility limitations. METHODS: We evaluated associations of thigh skeletal muscle measures (strength, area, and specific force) with total LUTS severity (American Urologic Association Symptom Index; AUASI) and voiding and storage subscores among 352 men aged ≥60 years enrolled in the Baltimore Longitudinal Study of Aging. Thigh muscle strength (Nm) was defined as maximum concentric 30°/s knee extensor torque, area (cm2), and specific force (Nm/cm2) defined as strength/area. Associations with AUASI score were estimated using multivariable linear regression and linear mixed models. RESULTS: Mean thigh muscle strength at baseline was 139.7Nm. In cross-sectional multivariable models, each 39Nm increment in thigh muscle strength and 0.28Nm/cm2 increment in specific force was associated with -1.17 point (95% CI: -1.93 to -.41) and -0.95 point (95% CI: -1.63 to -0.27) lower AUASI score, respectively. Similar associations were observed for voiding and storage subscores, although somewhat attenuated. In longitudinal analyses, baseline muscle measures were not associated with annual change in AUASI, and current changes in muscle measures and AUASI were unrelated. CONCLUSIONS: Cross-sectionally, higher thigh muscle strength and specific force were associated with decreased LUTS severity in older men. However, we did not observe concurrent worsening LUTS severity with declining thigh muscle strength, area, or specific force in longitudinal analyses.

BACKGROUND: Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common cause of end-stage renal disease (ESRD) in children. Approximately one third of children with CAKUT have lower urinary tract dysfunction (LUTD). AIM: This article highlights the important aspects that need to be considered in kidney transplantation of children with complex urogenital malformations. MATERIALS AND METHODS: The paper reviews the existing literature regarding the evaluation, preparation, perioperative management, and follow-up of children with complex urogenital malformations and ESRD undergoing renal transplantation. RESULTS: Comprehensive diagnostics are required before any pediatric kidney transplantation. If LUTD is suspected, voiding cystourethrography and a urodynamic examination should be performed. Treatment of symptomatic vesicoureterorenal reflux and LUTD is mandatory prior to pediatric kidney transplantation. Following successful kidney transplantation of children with congenital urogenital malformations, lifelong follow-up is required. Regular reevaluations of the bladder by means of urodynamic examinations are necessary. In patients following bladder augmentation with intestinal segments or urinary diversions in childhood, regular endoscopic examinations of the urinary tract are recommended to rule out secondary malignancy. CONCLUSION: Treatment of children with complex urogenital malformations should be carried out in centers with appropriate expertise.

INTRODUCTION: Dysfunctional voiding (DV) is a habitual voiding disorder caused by involuntary contraction or non-relaxation of the external urethral sphincter (EUS) during voiding. This contraction causes high post-void residuals (PVR), urinary incontinence and urinary tract infections (UTIs). Various treatments for DV are available, but some children do not respond. Intersphincteric botulinum toxin-A (BTX-A) may be a possible treatment for therapy-refractory children with DV. OBJECTIVE: The aim of this systematic review is to summarize the effects and safety of intersphincteric BTX-A as a treatment for therapy-refractory DV in children. METHODS: A systematic search in Embase, MEDLINE, Cochrane, and Web of Science databases was performed. Studies reporting on the usage of intersphincteric BTX-A as a treatment for DV in children were included. Data on PVR, maximum flow rate (Qmax), repeat injections and complications were extracted. RESULTS: From a total of 277 articles, five cohort studies were identified, reporting on 78 children with DV of whom 53 were female (68 %) and 25 were male (32 %). Sample sizes ranged from ten to twenty patients. Mean or median age at the time of intervention ranged from 8 to 10.5 years. Meta-analysis could not be performed due to lack of data. The narrative synthesis approach was therefore used to summarize the results. All studies showed significant decrease in PVR after BTX-A injection. Three studies showed a 33-69 % improvement on incontinence after BTX-A injection. Less UTIs were reported after treatment. A temporary increase in incontinence, UTIs and transitory numbness to the gluteus muscle were reported as side-effects. CONCLUSIONS: BTX-A could be a safe and effective treatment option for therapy-refractory DV in children by reducing PVR, UTIs and incontinence. Hereby, the synergistic effect of BTX-A and urotherapy should be emphasized in future management. Furthermore, this study identified gaps in current knowledge that are of interest for future research.

Since the identification of the human urinary microbiome, numerous studies have characterized this microbial community and improved our knowledge of its association with urinary diseases. This association between urinary diseases and microbiota is not confined to the urinary microbiota; it is interconnected with the microbiota of other organs. The gastrointestinal, vaginal, kidney, and bladder microbiota all affect urinary diseases because they work with their respective organs to control the growth and operation of the immune, metabolic, and nervous systems through dynamic bidirectional communication along the bladder-centered axis. Therefore, disturbances in the microbial communities may result in the emergence of urinary diseases. In this review, we describe the increasing and intriguing evidence of complicated and critical relationships that may contribute to the development and progression of urinary diseases through disruption of the microbiota in various organs.

BACKGROUND: Lower urinary tract symptoms (LUTS) and mobility limitations are bidirectionally associated among older adults, but the role of skeletal muscle remains unknown. We evaluated cross-sectional associations of muscle health and physical performance with LUTS. METHODS: We used data from 377 women and 264 men age>70 years in the Study of Muscle, Mobility and Aging (SOMMA). LUTS and urinary bother were assessed using the LURN Symptom Index-10 (SI-10;higher=worse symptoms). Muscle mass and volume were assessed using D3-creatine dilution (D3Cr) and magnetic resonance imaging. Grip strength and peak leg power assessed upper/lower extremity physical performance. 400m walk, Short Physical Performance Battery (SPPB), and Four Square Step Test (FSST) assessed global physical performance. Mobility Assessment Tool-short form (MAT-sf) assessed self-reported mobility. We calculated Spearman correlation coefficients adjusted for age, BMI, multimorbidity, and polypharmacy, chi-square tests, and Fisher's Z-test to compare correlations. RESULTS: Among women, LURN SI-10 total scores were inversely correlated with FSST (rs=0.11,P=0.045), grip strength (rs=-0.15,P=0.006), and MAT-sf (rs=-0.18,P=0.001), but not other muscle and physical performance measures in multivariable models. LURN SI-10 was not associated with any of these measures among men. 44% of women in the lowest tertile of 400m walk speed versus 24% in the highest tertile reported they were at least "somewhat bothered" by urinary symptoms (P<0.001) whereas differences among men were not significant. CONCLUSIONS: Balance and grip strength were associated with LUTS severity in older women but not men. Associations with other muscle and physical performance measures varied by LUTS subtype but remained strongest among women.
RESUMO
Augmentation cystoplasty (AC) is a well-established surgical option for the management of overactive bladder where conservative management has failed. We describe the case of a man in his 50s with chronic bladder dysfunction secondary to refractory detrusor overactivity and small capacity bladder. His lower urinary tract symptoms (LUTS) of urinary frequency and nocturia persisted despite pharmacological therapy and peripheral neural modulation; hence, he underwent surgical intervention for management of his bladder dysfunction. A robot-assisted clamshell enterocystoplasty was performed with a successful outcome. His LUTS have improved significantly post surgery. This case highlights modern advances in minimally invasive and robotic surgical techniques in the management of functional urological conditions. It also further demonstrates that the robotic approach is a viable option for AC, an operation traditionally performed as open surgery.

Functional bladder disorders including overactive bladder and interstitial cystitis may induce problems in many other parts of our body such as brain and gut. In fact, diagnosis is often less accurate owing to their complex symptoms. To have correct diagnosis of these diseases, we need to understand the pathophysiology behind overlapped clinical presentation. First, we focused on reviewing literatures that have reported the link between bladder and brain, as the patients with bladder disorders frequently accompanied mood disorders such as depression and anxiety. Second, we reviewed literatures that have described the relationship between bladder and gut. There exist many evidences of patients who suffered from both bladder and intestinal diseases, such as irritable bowel syndrome and inflammatory bowel disease, at the same time. Furthermore, the interaction between brain and gut, well-known as brain-gut axis, might be a key factor that could change the activity of bladder and vice versa. For example, the affective disorders could alter the activity of efferent nerves or autonomic nervous system that modulate the gut itself and its microbiota, which might cause the destruction of homeostasis in bladder eventually. In this way, the communication between bladder and brain-gut axis might affect permeability, inflammation, as well as infectious etiology and dysbiosis in bladder diseases. In this review, we aimed to find an innovative insight of the pathophysiology in the functional bladder disorders, and we could provide a new understanding of the overlapped clinical presentation by elucidating the pathophysiology of functional bladder disorders.
