Background: Overactive bladder (OAB) is a common functional disorder in paediatric populations and is associated with significant psychological burden and impaired quality of life. Although oxybutynin is widely used as first-line pharmacological therapy, a substantial proportion of children exhibit incomplete symptom control or limited tolerability. Emerging evidence suggests that targeting metabolic dysfunction, oxidative stress, and neuromuscular excitability may provide additional therapeutic benefit. This retrospective observational study evaluated the clinical impact of an adjunctive nutraceutical formulation containing myo-inositol, microlipodispersed magnesium, folic acid, and vitamin C (LEVIGON™ PRO, Sanitpharma; Milan, Italy) in children with OAB receiving oxybutynin. Methods: Medical records of children diagnosed with OAB were retrospectively reviewed. After applying inclusion and exclusion criteria, 120 patients aged 5–15 years were included and allocated to two groups based on documented treatment: oxybutynin plus LEVIGON™ PRO (Group A, n = 60) or oxybutynin alone (Group B, n = 60). The primary outcome was complete daytime urinary continence at Day 112. Secondary outcomes included weekly incontinence episodes, voiding frequency, bladder wall thickness, uroflowmetry parameters, and Patient Perception of Bladder Condition (PPBC) scores. An exploratory subgroup analysis was performed in 34 children with impaired fasting glucose (ifg), assessing fasting glucose, insulin, and homa-ir. results: by day 112, complete daytime continence was achieved in 61.7% of patients in group a and 48.3% in group b (absolute risk difference 13.4%; nnt ≈ 7.5; p = 0.14). across secondary endpoints, the combination therapy group showed significantly greater longitudinal improvements (group × time interaction, p < 0.05), including reductions in weekly incontinence episodes, voiding frequency, post-void residual volume, and ppbc scores, as well as increases in mean voided volume, qmax, and reductions in bladder wall thickness. in the ifg subgroup, greater reductions in fasting glucose, fasting insulin, and homa-ir were observed in group a compared with group b (p < 0.01). Both treatments were well tolerated, with no serious adverse events reported. conclusions: adjunctive nutraceutical therapy combined with oxybutynin was associated with greater improvements in several clinically relevant secondary outcomes in children with OAB, with a favourable tolerability profile. Although the primary endpoint did not reach statistical significance, the overall pattern of findings may suggest a possible additive benefit; however, these findings may be influenced by residual confounding inherent to the retrospective observational design. Therefore, the results should be considered hypothesis generating and require confirmation in prospective randomized controlled trials. Full article

The purpose of our study was to assess if spinacetin (SPC), a flavonoid found in spinach, can alleviate the cyclophosphamide (CYP)-induced changes in cystometric and inflammatory parameters indicative of the development of hemorrhagic cystitis. The animal experiments were conducted in female Wistar rats. The cohort of 60 animals was grouped as follows: I—control, II—CYP group, III—SPC group, and IV—CYP + SPC group. The cystometry and biochemical analyses were performed after a fortnight of SPC administration. SPC was found to restore normal cystometric parameters in CYP-induced cystitis and, similarly, it normalized c-Fos expression changes in the central micturition regions. SPC further prevented a massive increase in the bladder wall thickness/permeability due to exposition to CYP administration. CYP instillation resulted in the elevation of biomarkers found in urine (brain-derived neurotrophic factor, BDNF, and nerve growth factor, NGF), and in the bladder detrusor muscle (Rho kinase and vesicular acetylcholine transporter, VAChT), which were successfully restored after administration of SPC. As for the biomarkers in the bladder urothelium, the CYP-induced increases in TNF-α, IL-1β, IL-6, calcitonin gene-related peptide (CGRP), malondialdehyde, 3-nitrotyrosine, insulin-like growth factor-binding protein 3 (IGFBP-3), occludin, organic cation transporter 3 (OCT-3), orosomucoid-1 (ORM1), pituitary adenylate cyclase receptor 1 (PAC1), synaptosomal-associated protein 23 (SNAP23), SNAP25, and synaptic vesicle glycoprotein (SV2A) levels were attenuated by SPC. Finally, CYP administration resulted in a decrease in the heparin-binding EGF-like growth factor (HB-EGF), hemopexin (HPX), T-H protein, and tight junction protein (Z01), and we noted the successful restoration of all these changes in concentrations after application of SPC. In summary, SPC robustly mitigated cyclophosphamide (CYP)-induced cystometric dysfunction and biochemical alterations characteristic of iatrogenic hemorrhagic cystitis. These findings position SPC as a compelling therapeutic candidate and warrant further translational investigation for the management of CYP-induced bladder injury. Full article

Background/Objectives: Pelvic floor disorders affect up to 30% of adult females in the United States. Misdiagnosis occurs in nearly 45% to 90% of cases. Standardized pelvic anatomical measurements could improve diagnostic accuracy and treatment planning. We aimed to evaluate pelvic anatomical variations using magnetic resonance imaging (MRI). Methods: We analyzed MRI pelvic measurements from 250 women aged 20–90 years. Exclusion criteria included prior pelvic surgery (except hysterectomy), pelvic cancer, and use of alternative imaging modalities. Key measurements included anterior vaginal wall thickness (AVWT), bladder wall thickness (BWT), vaginal epithelium to bladder urothelium (VWBU), urethral length (UL), and inter-ureteral distances. A comprehensive statistical analysis was performed, including corrections for multiple comparisons. Results: While several anatomical measurements were correlated, a comprehensive analysis was performed to identify markers for clinical diagnoses. After applying Bonferroni correction for multiple comparisons, we found no statistically significant association between any of the measured anatomical parameters and a diagnosis of incontinence. Notably, an uncorrected difference in Bladder Wall Thickness (BWT) (p = 0.041) did not hold up to rigorous testing. To further assess its clinical utility, a Receiver Operating Characteristic (ROC) curve analysis for BWT as a predictor of incontinence yielded an aArea Under the Curve (AUC) of 0.19, indicating poor predictive validity. Conclusions: In this cohort, static anatomical measurements derived from MRI, including BWT, do not appear to be reliable markers for incontinence. Our findings suggest that the pathophysiology of this disorder is likely more dependent on functional or dynamic factors rather than simple static anatomical variations. Future research should focus on standardizing dynamic imaging parameters to better assess pelvic floor function. Full article

Spinal cord injury (SCI) frequently leads to neurogenic lower urinary tract dysfunction, for which appropriate bladder management is essential. While clinical care relies on continuous low-pressure drainage in the acute phase, rat models commonly use twice-daily manual bladder expression—a method known to generate high intravesical pressures and retention. This study evaluated the impact of this standard practice on bladder tissue remodeling by comparing it to continuous drainage via high vesicostomy in a rat SCI model. 32 female Lewis rats underwent thoracic contusion SCI and were assigned to either manual expression or vesicostomy-based bladder management. Over eight weeks, locomotor recovery, wound healing, and bladder histology were assessed. Vesicostomy proved technically simple but required tailored wound care and calibration. Results showed significantly greater bladder wall thickness, detrusor muscle hypertrophy, urothelial thickening, collagen deposition, and mast cell infiltration in the manual expression group compared to both vesicostomy and controls. In contrast, vesicostomy animals exhibited near-control levels across most parameters. These findings highlight that commonly used bladder emptying protocols in rat SCI models may overestimate structural bladder changes and inflammatory responses. Refined drainage strategies such as vesicostomy can minimize secondary damage and improve the translational relevance of preclinical SCI research. Full article

Oxidative stress and hypoxia-induced inflammation contribute to benign prostatic hyperplasia (BPH) progression. This study investigated the roles of urinary inflammatory and oxidative stress biomarkers in BPH patients. This prospective study enrolled 62 clinical BPH patients (33 treated medically, 29 surgically) and 20 controls. Symptom scores, uroflowmetry, and urinary biomarker levels were assessed at baseline and three months post-treatment. Before treatment, BPH patients exhibited elevated urinary levels of total antioxidant capacity (TAC), PGE2, IL-1β, and IL-6. Post-treatment, successful outcomes were reported in 63.6% of the medical treatment group and 86.2% of the surgical treatment group, with improvements in symptom scores and urinary flow rate, along with reductions in urinary 8-isoprostane, TAC, and IL-1β. Prior to treatment, voiding efficiency (VE) was negatively correlated with urinary IL-1β, IL-6, and IL-8 levels, while bladder wall thickness was positively correlated with TAC. After treatment, changes in VE were negatively correlated with changes in IL-1β, and changes in post-void residual urine were positively correlated with changes in IL-1β, IL-6, IL-8, and TNF-α. Urinary inflammatory and oxidative stress biomarkers may serve as non-invasive indicators of disease severity and treatment response in clinical BPH. Their significant correlations with clinical improvements underscore their potential utility in monitoring treatment efficacy. Full article

Bladder tumors in dogs represent approximately 2% of all malignant lesions recorded, with urothelial carcinoma being the most common and aggressive form. This study aimed to characterize the elastographic properties of canine urothelial carcinoma using ARFI (Acoustic Radiation Force Impulse) elastography and to evaluate its diagnostic capacity. Seven dogs with urothelial carcinoma and nine healthy dogs were evaluated, comparing shear wave velocity (SWV) and bladder wall thickness between the groups. The results showed that SWV was significantly higher in dogs with urothelial carcinoma (median of 2.53 m/s) compared with healthy dogs (median of 1.41 m/s) (p = 0.0045). Bladder wall thickness was also greater in dogs with carcinoma (0.28 ± 0.05 cm) compared to healthy dogs (0.14 ± 0.26 cm) (p = 0.0003). Receiver operating characteristic (ROC) curve analysis revealed a high sensitivity (100%) and specificity (88.9%) for SWV in differentiating healthy and neoplastic tissues. These findings suggest that ARFI elastography is a promising tool for diagnosing urothelial carcinoma in dogs, offering a noninvasive and quantitative approach that can complement traditional diagnostic methods. ARFI elastography may aid in early diagnosis and clinical management, improving the prognosis of patients with bladder neoplasia. Full article

Background/Objectives: Nocturnal enuresis (NE) is a common condition in children, affecting more than 10% of 6-year-olds and typically characterized by involuntary bedwetting during sleep. Although the exact causes remain unclear, ultrasound has emerged as a valuable tool for assessing bladder function and predicting therapy response and relapse, with several studies linking urological abnormalities like reduced bladder capacity and increased wall thickness to treatment outcomes. Methods: We performed a literature review utilizing five distinct search queries on PubMed with the following keywords: “enuresis & ultrasound”, “enuresis & bladder ultrasound”, “enuresis & bladder wall”, “enuresis & bladder capacity”, and “enuresis & bladder thickness”. We reviewed each article that met the eligibility criteria, and after a thorough selection, we included 17 studies. Results: Bladder ultrasound is a valuable tool for assessing bladder function and structure in children with NE, providing crucial insights into bladder capacity, wall thickness, and the bladder wall thickness index (BVWI). These ultrasound measurements correlate with the severity of NE and treatment success, aiding in personalized therapy, particularly for children with smaller bladder capacities and thicker bladder walls. Although studies have explored the link between ultrasound findings and treatment response, further research is needed to standardize methods and confirm these connections. Conclusions: The review highlights the predictive role of ultrasound in enuresis management, focusing on the response rate and choice of therapy. Future studies should investigate how bladder imaging can predict both short-term and long-term treatment outcomes, with current evidence supporting its use in customizing NE treatment for improved results.

Spinal cord injury (SCI) results in functional deficits below the injured spinal level. The descending serotonergic system in the spinal cord is critically involved in the control of motor and autonomic functions. Specifically, SCI damages the projections of serotonergic fibers, which leads to reduced serotonin inputs and increased amounts of spinal serotonergic receptors. Our previous pharmacological study demonstrated that brief administration of a highly selective 5-HT1A receptor agonist, NLX-112, improves lower urinary tract (LUT) function at the termination stage of thoracic 8 (T8) contusive SCI in rats. However, whether chronic activation of serotonin 5-HT1A receptors by NLX-112 after SCI is beneficial remains an unanswered question. Here, we evaluated the efficacy of long-term NLX-112 intervention starting from two weeks post-T8 contusive SCI for an additional six weeks. We evaluated locomotion, LUT function, bladder morphology, and the number of spinal 5-HT1A receptors in both L4 and L6/S1 spinal cord segments. Our results indicate that NLX-112 treatment significantly improves locomotion in a dose-dependent fashion, improves LUT function, reduces bladder weight and bladder wall thickness, and reduces the SCI-upregulated spinal 5-HT1A receptors compared to vehicle-treated SCI animals. These data suggest promising therapeutic potential for long-term NLX-112 activation of 5-HT1A receptors to treat SCI. Full article

Overactive bladder (OAB) has a significant impact on the quality of life; thus, it requires treatment that can be adhered to over a long period without undue side effects. The current treatment which uses an anticholinergic or β-3 agonist may fail to improve symptoms and has side effects, leading to high discontinuation rates. OnabotulinumtoxinA (OnabotA) detrusor injection has been approved for idiopathic OAB as a second-line treatment with good effectiveness and tolerability. This study used a visual analog scale (VAS) to assess the impact of the type of needle used for OnabotA detrusor injections under local anesthesia on the pain levels after each injection. This study included 68 female patients. We used three different needles with thicknesses ranging from 22 to 27 gauge, lengths between 4 and 5 mm, and different cuts. The sensation of pain was rated at each standardized injection location. Regardless of the needle used, the patients’ perceptions of pain at the beginning of the procedure were rated as being less than the subsequent injections. Most pain sensations were rated as low to moderate. The mean pain sensation on the VAS was 2.5 ± 0.3 overall, i.e., for all patients and needles used. Statistically significant differences in pain sensation were rated only at some locations of the bladder (on the back wall and the right side of the bladder). The single needles averaged the following pain scores: 2.8 ± 0.3 for needle A (20 G, 4 mm), 2.1 ± 0.3 for needle B (27 G, 5 mm), and 2.6 ± 0.4 for needle C (20 G, 4 mm, sharp cut 15°). The 27-gauge needle caused significantly less pain, and it had no negative impact due to its length, which was 1 mm longer than the other needles. Thus, the needle thickness was a decisive factor in the patients’ perceptions of pain. Full article

Introduction: Transurethral injections into the bladder wall with botulinum toxin are an established treatment for refractory overactive bladder or detrusor overactivity. With the current injection technique, an average of approx. 18% and up to 40% of botulinum toxin is injected next to the bladder wall, potentially causing reduced efficacy or non-response. The article aims to evaluate the reasons for incorrect injections and propose strategies for complete delivery of the entire botulinum toxin fluid into the bladder wall. Material and Methods: Unstructured literature search and narrative review of the literature. Results: Incorrect injection of botulinum toxin fluid next to the bladder wall is caused by pushing the injection needle too deep and through the bladder wall. Bladder wall thickness decreases with increasing bladder filling and has a thickness of less than 2 mm beyond 100 mL in healthy individuals. Ultrasound imaging of the bladder wall before botulinum toxin injection can verify bladder wall thickness in individual patients. Patient movements during the injection therapy increase the chance of incorrect placement of the needle tip. Conclusions: Based on the literature search, it is helpful and recommended to (1) perform pretreatment ultrasound imaging of the bladder to estimate bladder wall thickness and to adjust the injection depth accordingly, (2) fill the bladder as low as possible, ideally below 100 mL, (3) use short needles, ideally 2 mm, and (4) provide sufficient anesthesia and pain management to avoid patient movements during the injection therapy.

Background: We present a case series of Neuroendocrine Carcinoma of the Urinary Bladder (NECB) to analyse their radiologic appearance on CT, find a “Radiomic signature”, and review the current literature. Methods: 14 CT cases of NECB were reviewed and compared with a control group of 42 patients with high-grade non-neuroendocrine bladder neoplasm for the following parameters: ring enhancement; implantation site; dimensions; density; margins; central necrosis; calcifications; number of lesions; wall thickness; depth of invasion in the soft tissue; invasion of fat tissue; invasion of adjacent organs; lymph-node involvement; abdominal organ metastasis. To extract radiomic features, volumes of interest of bladder lesions were manually delineated on the portal-venous phase. The radiomic features of the two groups were identified and compared. Results: Statistical differences among NECB and control group were found in the prevalence of male sex (100% vs. 69.0%), hydronephrosis (71.4% vs. 33.3%), mean density of the mass (51.01 ± 15.48 vs. 76.27 ± 22.26 HU); product of the maximum diameters on the axial plane (38.1 ± 59.3 vs. 14.44 ± 12.98 cm2) in the control group, trigonal region involvement (78.57% vs. 19.05%). About the radiomic features, Student’s t-test showed significant correlation for the variables: “DependenceNonUniformity” (p: 0.048), “JointAverage” (p: 0.013), “LargeAreaLowGrayLevelEmphasis” (p: 0.014), “Maximum2DDiameterColumn” (p: 0.04), “Maximum 2DDiameterSlice” (p: 0.007), “MeanAbsoluteDeviation” (p: 0.021), “BoundingBoxA” (p: 0.022) and “CenterOfMassB” (p: 0.007). Conclusions: There is a typical pattern (male patient, large mass, trigonal area involvement) of NECB presentation on contrast-enhanced CT. Certain morphological characteristics and encouraging results about Radiomic features can help define the diagnosis. Full article

Traumatic spinal cord injury (SCI) results in the time-dependent development of urinary impairment due to neurogenic detrusor overactivity (NDO) and detrusor-sphincter-dyssynergia (DSD). This is known to be accompanied by massive changes in the bladder wall. It is presently less clear if the urethra wall also undergoes remodelling. To investigate this issue, female rats were submitted to complete spinal transection at the T8/T9 level and left to recover for 1 week and 4 weeks. To confirm the presence of SCI-induced NDO, bladder function was assessed by cystometry under urethane anesthesia before euthanasia. Spinal intact animals were used as controls. Urethras were collected and processed for further analysis. Following thoracic SCI, time-dependent changes in the urethra wall were observed. Histological assessment revealed marked urethral epithelium reorganization in response to SCI, as evidenced by an increase in epithelial thickness. At the muscular layer, SCI resulted in strong atrophy of the smooth muscle present in the urethral sphincter. Innervation was also affected, as evidenced by a pronounced decrease in the expression of markers of general innervation, particularly those present in sensory and sympathetic nerve fibres. The present data show an evident impact of SCI on the urethra, with significant histological rearrangement, accompanied by sensory and sympathetic denervation. It is likely that these changes will affect urethral function and contribute to SCI-induced urinary dysfunction, and they deserve further investigation. Full article

Ultrasound measurements of detrusor muscle thickness have been proposed as a diagnostic biomarker in patients with bladder overactivity and voiding dysfunction. In this study, we present an approach based on deep learning (DL) and dynamic programming (DP) to segment the bladder sac and measure the detrusor muscle thickness from transabdominal 2D B-mode ultrasound images. To assess the performance of our method, we compared the results of automated methods to the manually obtained reference bladder segmentations and wall thickness measurements of 80 images obtained from 11 volunteers. It takes less than a second to segment the bladder from a 2D B-mode image for the DL method. The average Dice index for the bladder segmentation is 0.93 ± 0.04 mm, and the average root-mean-square-error and standard deviation for wall thickness measurement are 0.7 ± 0.2 mm, which is comparable to the manual ground truth. The proposed fully automated and fast method could be a useful tool for segmentation and wall thickness measurement of the bladder from transabdominal B-mode images. The computation speed and accuracy of the proposed method will enable adaptive adjustment of the ultrasound focus point, and continuous assessment of the bladder wall during the filling and voiding process of the bladder.

A-F Betafood® is a whole food-based health product. The product contains phytonutrients and bioactives with antioxidant properties that may support gallbladder and liver function. Herein, we investigated the efficacy of A-F Betafood® on gallbladder and liver function. In this randomized, placebo-controlled, parallel study fifty overweight but otherwise healthy adults received A-F Betafood® or placebo for 12 weeks. Gallbladder function as assessed by gallbladder volume, ejection fraction (GBEF), ejection rate, wall thickness and liver function determined via aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase, and high-sensitivity c-reactive protein analysis at baseline and week 12 were the primary outcomes. Total cholesterol, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, triglycerides, and oxidative stress markers including oxidized low-density lipoprotein, tumor necrosis factor-α, adiponectin and malonyldialdehyde (MDA) were assessed as secondary outcomes. A-F Betafood®-supplementation significantly reduced gallbladder wall thickness (p = 0.049) by 9% compared to placebo from baseline to week 12. The A-F Betafood® group alone had significant improvements in gallbladder volume (32%; p = 0.044) and GBEF (19%; p = 0.047) at week 12. There were no changes in liver function, oxidative stress markers or blood lipid concentrations, though MDA concentrations decreased in both groups. Our findings demonstrate A-F Betafood®-supplementation significantly improves measures of gallbladder function and support healthy gallbladder function in the individuals with gall bladder condition.

Background and Objectives: Rugby players engage in demanding, high loading muscular activity in the spine. Study of the abdominal wall architecture in female rugby athletes is relevant to the possible muscular asymmetry secondary to sport practice and the relationship between the abdominal wall and the pelvic floor muscles. Activation of the transversus abdominis (TrAb) generates an increase in the bladder neck muscle. Moreover, an increased interrecti distance (IRD) is related to urinary incontinence and has a higher prevalence in athletic women. The aim of the present study was to compare and quantify, with ultrasound imaging (USI), the thickness of the transversus abdominis (TrAb), external oblique (EO), internal oblique (IO), rectus abdominis (RA), and interrecti distance (IRD) in female rugby players versus non-athletic women in order to improve upon existing knowledge about abdominal wall configuration in female athletes. Materials and Methods: A sample of 32 women was recruited at the Universidad Europea Research Lab and divided in two groups: a rugby group (n = 16) and a non-athletic women group (n = 16). The thickness of the TrAb, EO, IO, RA, and IRD were assessed by USI in both groups. Results: There were statistically significant differences for the ultrasound evaluation thickness of the right TrAb (p = 0.011; d = 0.10), EO (p = 0.045; d = 0.74), IO (p = 0.003; d = 1.32), and RA (p = 0.001; d = 1.38) showing a thickness increase for the rugby group with respect to the control group. For the IRD thickness, there were no significant differences (p > 0.05) between groups. Conclusions: An increased TrAb, IO, EO, and RA thickness may be shown in female rugby players versus non-athletic women. Nevertheless, statistically relevant differences were not found for the IRD between both groups. Full article
