Abstract
INTRODUCTION Kidney ureter bladder radiography (KUB) is widely used for the evaluation of constipation in children with bladder and bowel dysfunction (BBD); however, there is varying evidence to support its routine diagnostic use. One drawback to KUB is radiation exposure. The dangers of radiation in children are well-documented, and per As Low As Reasonably Achievable, non-beneficial radiation should be avoided. This risk is especially high in children who undergo repeated imaging in the follow up of constipation treatment. OBJECTIVE We sought to assess the utility of KUB in diagnosing children with BBD by comparing it to four diagnostic tests and/or validated instruments: the Dysfunctional Voiding Symptom Score (DVSS), Rome IV criteria, rectal diameter on ultrasound (RD), and the Bristol Stool Form Score (BSFS). STUDY DESIGN We prospectively enrolled a cohort of patients presenting to an academic pediatric urology practice with symptoms of BBD. Severity of stool burden on KUB (mild, moderate, or severe), RD on ultrasound (≥3.4 cm), DVSS, Rome IV, and BSFS were obtained for each patient. All imaging was interpreted by a pediatric radiologist and pediatric urologist. Primary outcomes were the association between the four diagnostic tests and KUB stool burden. Bivariate analysis of all individual variables versus KUB was performed, as well as multivariate regressions to determine if multiple measures were predictive of KUB stool burden when combined. RESULTS Between October 2020 and May 2022, 50 patients were enrolled. All children were under the age of 18, with a median age of 8 years (IQR 3-13). 38 % were male. Median BMI-for-age-percentile was 80.8 (IQR 50.3-98.3). When comparing individual variables to KUB in bivariate analyses, it was found that RD on ultrasound is predictive of significant stool burden on KUB (p = 0.03). No other individual variables were predictive. In the multivariate analyses, no combination of tests was found to be predictive of KUB. DISCUSSION We compared the effectiveness of four commonly used diagnostic tests in children with BBD to validate the use of KUB. In conclusion, our results support the use of RD on ultrasound as a non-radiating alternative to KUB to assess stool burden. Data also suggest that KUB for fecal load does not correlate with urinary (DVSS) or bowel (Rome IV, BSFS) symptoms in BBD, and that symptoms scores should still be used independently for diagnosis and monitoring of treatment response. CONCLUSION In conclusion, KUB has a limited role in the diagnosis of BBD.

Abstract
Objective: To create a nomogram to evaluate the risk of upper urinary tract damage (UUTD) in patients with neurogenic bladder (NGB) Methods: A retrospective analysis was conducted on 301 patients with NGB who were admitted to certain hospitals. Data collected included clinical symptoms, patients' characteristics, laboratory parameters, imaging findings, and urodynamic parameters. The least absolute shrinkage and selection operator(LASSO)regression model was used to optimise the selection of predictors. Multivariate logistic regression analysis was performed to develop a UUTD risk predictive model. Validation was performed by bootstrap. Results: The predictors included in the nomogram included sex, duration of disease, history of UTI, bladder compliance, and fecal incontinence. The model presented good discrimination with a C-index value of 0.796 (95% confidence interval: 0.74896-0.84304) and good calibration. The C-index value of the interval validation was 0.7872112. The results of decision curve analysis (DCA) demonstrated that the UUTD-risk predictive nomogram was clinically useful. Conclusion: The nomogram incorporating the sex, duration of disease, history of UTI, bladder compliance, and fecal incontinence could be an important tool of UUTD risk prediction in NGB patients.

Abstract
OBJECTIVE Bowel and bladder dysfunction (BBD) is a clinical syndrome defined by the coexistence of constipation and lower urinary tract symptoms. Although BBD is a common condition in pediatric urology and can cause significant stress to patients/parents, clinical diagnosis of BBD has not been standardized. Bowel and bladder dysfunction instruments have gained popularity over the past decade to aid in diagnosis. In this review, the currently published BBD symptom questionnaires were summarized and an analysis on their psychometric validation process was provided. SUBJECTS/PATIENTS PubMed was searched for articles on BBD symptom questionnaires/instruments/surveys since 2000. Two investigators (R.Y.J. & M.S.K.) conducted the search in duplicate. The search was limited to English language. The included search terms were 'dysfunctional elimination syndrome', 'bowel and bladder dysfunction', 'dysfunctional voiding', 'voiding dysfunction symptom score', and 'dysfunctional voiding symptom scale'. Reference lists of included studies were screened for missed studies. Unpublished abstracts presented at the following scientific meetings were also manually searched for: the American Urological Association, the Society for Pediatric Urology, and the American Academy of Pediatrics Section on Urology. Exclusion criteria included articles in languages other than English, articles not related to BBD questionnaires, and articles not pertaining to pediatric patients. RESULTS After initial search, a total of 54 articles were obtained. Of the seven questionnaires reviewed, only one did not measure sensitivity or specificity. Almost all questionnaires showed excellent discriminative property with an Area under the curve (AUC) >0.85. Criterion validity was not reported in any of the questionnaires. Known-group validation was used as a common method to evaluate construct validity. Internal consistency was reported in 2 studies, and only 1 study measured questionnaire responsiveness during initial validation. CONCLUSIONS Although BBD is a common pediatric urology condition; a large amount of heterogeneity exists in the questionnaires' psychometric testing and validation process. To further improve the diagnosis and management of BBD in pediatric patients, there is a need for consensus on the gold standard questionnaire measure.

Abstract
PURPOSE To characterize the course of treatment for nonmonosymptomatic enuresis with overactive bladder (OAB) in a real clinical setting. METHODS Data from 111 OAB patients with moderate to severe enuresis were analyzed. The baseline analysis included a questionnaire, voiding diary, uroflowmetry with postvoid residual urine measurement, and plain abdominal radiography of the kidneys, ureters, and bladder (KUB). Following standard urotherapy for 1 month, anticholinergic medication was administered with or without laxatives. Desmopressin was added if there was a partial response to OAB. Patients were followed every 3 months to evaluate the status of OAB and enuresis. Multivariate analysis was performed to identify predictors associated with the lack of complete response (CR) in enuresis at 12 months. RESULTS Following 12 months of treatment, 64% and 88% of patients experienced at least partial response in enuresis and OAB, respectively. Urgency improved more quickly than enuresis, supporting the need to address daytime symptoms before enuresis. Seventy-nine patients (71%) had fecal impaction on KUB and/or subjective constipation. The combination of anticholinergics with either laxatives or desmopressin fared better than anticholinergics alone. Daytime incontinence and anticholinergics- only treatment were associated with a lack of CR during 12 months of treatment. Conclusions The data confirmed the validity of addressing OAB before treating enuresis. The results of this study also highlight the need to address fecal impaction. Patients should be counseled about the need for a prolonged course of treatment before starting treatment. Anticholinergics should be accompanied with either desmopressin or laxatives for better control of enuresis.

Abstract
Overactive bladder (OAB) is a ubiquitous syndrome that is defined by urinary urgency with, or without urinary incontinence. OAB is observed in all parts of the world, with a prevalence of 5-12% in children (5-10 years of age) and a prevalence of 0.5% in older adolescents (16-18 years of age). Published data indicate that around a third of children with OAB are likely to become adults with similar complaints. Studies in children and in adults with OAB indicate that these individuals are more likely to also have anxiety, depression and attention deficit problems, and that appropriate treatment of these comorbidities can often improve the patient's OAB symptoms. Furthermore, data from twin studies and familial surveys seem to indicate a genetic component of OAB. Pharmacological treatments of OAB in children have improved in the past 5 years, moving beyond anticholinergic agents and including the off-label use of α-blockers, β3-agonists and intravesical botulinum toxin. Use of several different electrical stimulation techniques is also effective, both as first-line treatments, and for patients with treatment-refractory symptoms. Overall the outlook of children with OAB seems to be improving, with a greater understanding of the pathophysiology of this syndrome. Treatment modalities that target the source of the underlying problem, especially in children, are likely to provide the best patient outcomes.

Abstract
The past 30 years have seen broad changes in the diagnosis and management of vesicoureteral reflux (VUR). Recently, a clinical debate has generated an open discussion in academic circles. New evidence has shifted treatment patterns away from widespread surgical management and recently brought into question some pharmacologic treatments. VUR is usually not hazardous by itself but is a significant risk factor for urinary tract infection (UTI) and less commonly, renal scarring and insufficiency. Given the costs and morbidity of UTI as well as the potential for significant renal injury, our approach remains conservative. Careful follow-up, parental education about pathophysiology and management of VUR and UTI, and management of bowel and bladder dysfunction (BBD) when present, are the foundation of treatment. Additionally, though we recognize the limitation of continuous antibiotic prophylaxis (CAP), we believe the benefits outweigh the risks and costs for many patients. Careful observation can be considered in patients with a single medical home, parental understanding of what UTI signs and symptoms are, low grade VUR, no history of complicated UTIs and close follow-up. Surgical management remains a relevant option for select patients who fail conservative measures with breakthrough UTIs or failure to resolve. Minimally invasive surgical options are available with acceptable outcomes though open ureteroneocystostomy still carries the highest success rate.

Abstract
Vesicoureteral reflux (VUR) is a significant risk factor for clinical pyelonephritis and renal scarring. In 2010, the American Urological Association (AUA) reported that bladder and bowel dysfunction (BBD), which is common in patients with VUR, increases the risk of breakthrough UTI in children receiving antibiotic prophylaxis, reduces the success rate for endoscopic injection therapy, and increases the risk of postoperative UTI, irrespective of the surgical success rate for VUR. Accordingly, physicians are strongly recommended to investigate BBD in their patients with VUR. Symptoms and signs of BBD include urinary frequency and urgency, prolonged voiding intervals, daytime wetting, perineal and penile pain, holding manoeuvres (posturing to prevent wetting), constipation, and encopresis. Primary assessment tools include the Pediatric Symptom Checklist, urinalysis, urine culture, bladder diary, measurement of the postvoid residual urine volume, Dysfunctional Voiding Symptom Score, uroflow with electromyography, and Bristol Stool Form Score. The Rome III criteria can also be used for diagnostic assessment of bowel function. Treatment of BBD should be individualized, directed at symptomatic and objective improvement, and can include behavioural modification, biofeedback, selective use of anticholinergics and α-blockers, and bowel management.
