Scoring system to evaluate meaningful fecal impaction in patients with lower urinary tract dysfunction with simple radiography (KUB).

PURPOSE: The management of bowel bladder disorder (BBD) has only been indicated for subjective constipation without objective evidence. We attempted to highlight the radiological findings in patients with BBD and construct a scoring system to identify patients with BBD prior to treatment. MATERIALS AND METHODS: Forty-five patients with lower urinary tract dysfunction (LUTD) received polyethylene glycol for 2 months before bladder medication for LUTD. Based on partial response to LUTD following treatment, we divided the patients into LUTD-fecal impaction (FI) and LUTD not attributed to FI (LUTD-NFI) groups. Pre/post-treatment kidney, ureter, and bladder (KUB) were compared with respect to several radiographic parameters. Items with significant changes after treatment were included in the scoring system. The accuracy and inter-rater agreement were also evaluated. RESULTS: Cecal dilation, descending colon dilation, fecal quality, and overall haziness were found to undergo significant changes after laxative treatment. We assigned 0 to 2 points for each item, with a total score of 8. Receiver operating characteristic curve analysis revealed a cutoff value of 5 between LUTD-FI and LUTD-NFI, with 79% sensitivity and 88% specificity. The scoring system was instructed to six doctors who were unaware of it and was then tested on previous patients, which showed a substantial concordance rate (κ=0.79, p<0.05). CONCLUSIONS: Fecal scoring system based on KUB was beneficial in identifying children with LUTD attributed to FI. This may provide an opportunity to obtain objective FI data as an alternative to subjective assessment of constipation.

Does KUB play a role in the diagnosis of bladder bowel dysfunction?

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.

Longitudinal follow-up of bladder function in children who participated in the Swedish Reflux Trial.

BACKGROUND: Several publications have reported the coexistence of vesicoureteral reflux (VUR) and bladder dysfunction in children. Whether this dysfunction remains in the longer term is not yet known. OBJECTIVE: This study revisited children who participated in the Swedish Reflux Trial (SRT) with the primary aim of evaluating whether bladder and bowel dysfunction (BBD) in these patients persisted until adolescence. The secondary aim was to evaluate two BBD subgroups, and relations to recurrent urinary tract infections (UTI). STUDY DESIGN: Of the 161 eligible children at SRT study-end, 73 children participated. Their bladder function was evaluated longitudinally using a validated BBD questionnaire with symptom score (cut-off ≥7) and uroflowmetry, at five (T2) and ten years (T3) after study-end. T1 was the SRT study-end. Besides BBD, the sub-diagnoses overactive bladder (OAB) and dysfunctional voiding symptoms (DVS) were calculated from symptom scores. RESULTS: BBD was diagnosed in 37% of children at mean age 3.7 years, which decreased with age to 23% of adolescents (mean age 15.7). DVS and OAB subgroups were equally common at T1, but only DVS was identified at the last follow-up (T3) (p = 0.0008). Recurrent UTIs were seen in 17% at T3 and were more common in patients with BBD (p = 0.038). The gender distribution of BBD also changed, from being equally common at the end of the SRT to affecting mainly adolescent girls at the last follow-up (p = 0.022). Information was available regarding VUR status after repeat VCUGs during follow-up in 22 patients, 12 of them after endoscopic treatment. An improvement in VUR grade was found in the 22, but during follow-up numbers with BBD or UTI did not differ between treated and non-treated groups. DISCUSSION: The prevalence of BBD decreased from 37% at 3-4 years of age to 23% in adolescence, when it was almost exclusively seen in girls. BBD and the subgroup DVS were associated with UTI. Even if epidemiological studies have established a predisposition to bladder symptoms and UTI in girls, little is known about bladder function in adolescents with a history of VUR during the first years of life. One limitation of the study was the number of patients participating. Also, the number of patients with kidney damage was more common in the cohort. CONCLUSION: In this longitudinal follow-up of BBD in children with VUR, the number of children with BBD decreased with age. In adolescence, both BBD and recurrent UTIs mainly affected girls.

Complication Pattern of Sacral Primary Tumor Resection: A Study on the Risk Factors of Surgical Site Infection and Bowel or Bladder Dysfunction and Their Associations with Length of Hospital Stay.

STUDY DESIGN: Retrospective open cohort study. PURPOSE: The current study aimed to explore the pattern of complications after primary sacral tumor resection, to investigate the possible effect of several perioperative parameters on the development of complications, and to identify which complications are associated with the length of hospital stay (LOS). OVERVIEW OF LITERATURE: Primary sacral tumor (pST) resection is associated with a high complication rate. However, the number of studies on these complications and their effect on LOS is limited. METHODS: The clinical data of 140 patients with pST surgeries and 106 subsequent patients with local recurrence surgeries in four subgroups (index surgery, local recurrence surgery, malignant, and benign tumor) were prospectively collected and analyzed. The prognostic value of several perioperative factors on the development of surgical site infection (SSI), bowel and bladder dysfunction (BBD), and LOS was investigated using the logistic and linear regression models. RESULTS: The overall complication rates were 61.2% after index surgeries and 50.9% after local recurrence surgeries. The most frequent complications were SSI, vegetative dysfunction, urinary tract infections, and neurological deterioration. Age >55 years, malignant tumors, and red blood cell transfusion had a predictive effect on the development of SSI in the logistic model (p<0.01, R2=0.43). Bilateral S2 or S3 resection commonly caused postoperative BBD (chi-square test=62.5, degrees of freedom=4, p<0.001). In the multiple linear regression model, wound dehiscence, BBD, systemic and urinary tract infection, cerebrospinal fluid leak, and neurologic deterioration were associated with a significantly long LOS (p<0.01, R2=0.62). CONCLUSIONS: Surgical resection of pSTs has a high complication rate. Its common complications are SSI and BBD, both of which can have a significant influence on global therapeutic outcome. Malignant tumor diagnosis, old age, and red blood cell transfusion can remarkably increase the risk of SSI. Further, the development of BBD is significantly associated with the number of resected sacral nerve roots. By decreasing perioperative complications, LOS can decrease significantly.

Urogenital urobiome of healthy children does not differ from that of children with bladder and bowel dysfunction.

INTRODUCTION: The pediatric urinary microbiome (urobiome) has been studied in the context of healthy children and children with genitourinary pathologies including neuropathic bladder, urinary tract infection (UTI) and nephrolithiasis. Little is known about the urobiome of children with bladder and bowel dysfunction (BBD), a condition that is an established risk factor of UTI. We hypothesized that the symptoms of a child with BBD may be related to urobiome composition. OBJECTIVE: To evaluate the urogenital urobiome's role in BBD, we compared the urogenital urobiomes of children with and without BBD. STUDY DESIGN: We performed a prospective case-control pilot study at a single large, academic children's hospital. Cases included toilet trained prepubertal females over 2 years of age with BBD established through a validated scoring system and controls included asymptomatic, presumably healthy, children. Children were excluded if they had symptoms or lab work consistent with a concurrent UTI or antibiotic course for any reason within the prior 14 days. We performed 16 S ribosomal RNA gene sequencing and expanded quantitative urine culture on clean catch urine samples. To compare within sample (alpha) diversity, we used the Kruskal-Wallis test. To compare between sample (beta) diversity, we calculated the Bray-Curtis distance and performed the PERMANOVA test. RESULTS: Data from 25 children with BBD and 8 asymptomatic controls were analyzed. The demographic and clinical characteristics of the two comparison groups were similar, though a higher proportion of Black children were included in the asymptomatic control group. Neither alpha diversity nor beta diversity was significantly different between the two groups. The core microbiome of the BBD group included all the genera in the core urogenital urobiome of the controls, plus additional genera associated with opportunistic infection and/or UTI, including Escherichia, Campylobacter and Streptococcus. DISCUSSION: The results of both the 16 S sequencing and expanded quantitative urine culture in this small study suggest that the urogenital urobiomes of children with BBD do not differ significantly from those of asymptomatic children. However, the core urogenital urobiome of children with BBD included genera associated with opportunistic infection and/or UTI. This study was limited by the sample collection method ("clean catch" midstream voided urine samples, which introduce the possibility of vulvovaginal contamination), small sample size, and unequal balance of patient characteristics between the two study groups. CONCLUSION: The urogenital urobiomes of children with and without BBD do not appear to significantly differ. Larger studies are needed to confirm these findings.

Noninvasive Evaluation of Bladder Bowel Dysfunction and its Extrapolation as Biofeedback Therapy to Train Pelvic Floor Muscles.

Aims: This study aimed to evaluate the noninvasive methods to diagnose bladder bowel dysfunction (BBD) and its extrapolation on biofeedback therapy and pelvic floor exercises (PFE) to treat these children. Settings and Design: A retrospective cohort study at a tertiary care center was conducted between January 2010 and December 2020, on 204 children, aged 4-18 years, arbitrarily divided into two groups-4-12 and 13-18 years. Subjects and Methods: Details of lower urinary tract dysfunction were recorded as International Children's Continence Society nomenclature. Bowel habits were recorded and functional constipation was graded using ROME IV. The data recorded were urine analysis, a voiding diary, a dysfunctional voiding symptom score, and uroflowmetry with or without electromyography. Ultrasonography, voiding cystourethrogram, and magnetic resonance imaging were done in appropriate cases. Dysfunctional Voiding Severity Score was used to assist the evaluation and outcome. The treatment protocol included urotherapy, uroflow biofeedback, PFEs, prophylactic antibiotics, pharmacotherapy, and treatment of constipation. Statistical Analysis Used: Statistical analysis was done using SPSS version 26 and paired t-test was used for comparison and calculating P value. Results: There was a significant improvement in DVSS and uroflow parameters. However, the magnitude of change produced varied among the age groups. Patients who failed to show any clinical benefit were subjected to alternative therapies such as intrasphincteric Botulinum A toxin with or without neuromodulation. Conclusions: Integrated uroflow biofeedback (IUB) and PFE expedites the recovery by supplementing the effect of urotherapy; hence, this should be offered to all children with BBD.

Primary Vesicoureteral Reflux and Renal Scarring.

Vesicoureteral reflux (VUR) is the commonest congenital anomaly of urinary tract in children. It is mostly diagnosed after a urinary tract infection or during evaluation for congenital anomalies of the kidney and urinary tract. High-grade VUR, recurrent pyelonephritis, and delayed initiation of antibiotic treatment are important risk factors for renal scarring. The management of VUR depends on multiple factors and may include surveillance only or antimicrobial prophylaxis; very few patients with VUR need surgical correction. Patients with renal scarring should be monitored for hypertension and those with significant scarring should also be monitored for proteinuria and chronic kidney disease.

TeleBBD: Telehealth management of bladder bowel dysfunction - A provider survey of benefits and limitations.

INTRODUCTION: Bladder bowel dysfunction (BBD), defined by the International Children's Continence Society (ICCS) as a spectrum of lower urinary tract and bowel symptoms, represents to up to 40% of pediatric urology consults. Management of BBD involves strict behavioral management with frequent follow ups by urology advanced practice providers (APPs). If left untreated, patients may develop secondary comorbidities that impact their renal and/or bladder function, bowel function, and psychosocial well-being. Previous studies have reported feasibility for virtual post-operative visits and prenatal consultations, however, telehealth management of BBD, or TeleBBD, has not yet been studied. The goal of this study is to survey APPs in pediatric urology to understand how TeleBBD compares to in-person visits, and identify benefits and limitations of TeleBBD. STUDY DESIGN: An online survey via Qualtrics was designed based on current practice guidelines for BBD management and telehealth considerations. Survey was distributed in September 2020 via the Pediatric Urology Nurses & Specialists listserv. Group qualitative coding was completed by the authors to generate themes that emerged from the results. RESULTS/DISCUSSION: A total of 53 APPs from across 21 states in the US completed the online survey, with 49 (92%) APPs reporting currently providing TeleBBD. Those who did not provide TeleBBD typically do not manage BBD patients. Summary Table shows the comparison of TeleBBD with in-person visits, with many elements of TeleBBD better or the same as in-person visits. APPs reported that TeleBBD has been most beneficial in increasing access and overall improvement in follow up which is significant for management of this chronic condition. Barriers include access to technology/internet and inability to perform full physical exams via televisit. Limitations of the study include lack of validated survey and small sample size. Overall increased access and improved patient adherence and resolution from BBD is significant for this patient population for prevention of secondary comorbidities. CONCLUSION: This is the first study to survey APPs across the US specifically exploring indication of TeleBBD as well as comparison of TeleBBD with in-person visits. The perception of improved access to care and less no-show rates is significant especially during the pandemic in providing continuity of care and prevent secondary comorbidities. Additionally, TeleBBD was felt to be just as effective as in-person visits for patient adherence to treatment, and other components of care, with the exception of ability to provide physical exams. Providers leveraged the benefits of TeleBBD and shared strategies for best practices.

Asian guidelines for urinary tract infection in children.

The followings are the level of evidence (LE) and grade of recommendation (GR) on pediatric UTI in Asia. Classification according to the sites of infection (lower versus upper tract), the number of episode (first versus recurrent), the severity (simple versus severe), or the existence of complicating factor (uncomplicated versus complicated) is useful to differentiate children with UTI whether they are at risk of renal damage or not (LE: 2, GR: B). Diagnosis of UTI requires both urinalysis that suggests infection and positive urine culture (LE:3, GR B). For pre-toilet trained children, urine specimen for culture should be collected by urethral catheterization or suprapubic aspiration. For toilet trained children, midstream clean catch urine is reliable (LE: 3, GR: A). Urine culture is considered positive if it demonstrates growth of a single bacterium with the following colony counts: (1) any growth by suprapubic aspiration, (2) >5 × 104 CFU/ml by urethral catheterization, or (3) >100,000 CFU/ml by midstream clean catch (LE:3, GR: B). For children with febrile UTI, renal and bladder ultrasonography (RBUS) should be routinely performed as soon as possible (LE: 3, GR: C). RBUS should be followed up 6 months later in children with acute pyelonephritis and/or VUR (LE: 3, GR: C). Acute DMSA scan can be performed when severe acute pyelonephritis or congenital hypodysplasia is noted on RBUS or when the diagnosis of UTI is in doubt by the clinical presentation (LE: 3, GR: C). Late DMSA scan (>6 months after the febrile UTI) can be performed in children with severe acute pyelonephritis, high-grade VUR, recurrent febrile UTIs, or abnormal renal parenchyma on the follow-up RBUS (LE: 3, GR: C). Top-down or bottom-up approach for febrile UTI is suggested for the diagnosis of VUR. For top-down approach, VCUG should not be performed routinely for children after the first febrile UTI. VCUG is indicated when abnormalities are apparent on either RBUS or DMSA scan or both (LE: 2, GR: B). VCUG is also suggested after a repeat febrile UTI (LE:2, GR: B). Appropriate antibiotic should be given immediately after urine specimen for culture has been obtained (LE:2, GR: A). Initiating therapy with oral or parenteral antibiotics is equally efficacious for children (>3 months) with uncomplicated UTI (LE: 2: GR: A). The choice of empirical antibiotic agents is guided by the expected pathogen and the local resistance patterns (LE: 2, GR: A). For children with febrile UTI, the total course of antibiotic therapy should be 7-14 days (LE: 2, GR: B). Circumcision may, but not definitively, reduce the risk of febrile UTI in males and breakthrough febrile UTI in males with VUR. Circumcision should be offered to uncircumcised boys with febrile UTI and VUR in countries where circumcision is accepted by the general population (LE: 3, GR: B), while in countries where childhood circumcision is rarely performed, other measures for febrile UTI/VUR should be the preferred choice (LE: 4, GR: C). Bladder bowel dysfunction (BBD) is one of the key factors of progression of renal scarring (LE: 2). Early recognition and management of BBD are important in prevention of UTI recurrence (LE:2, GR: A). Antibiotic prophylaxis to prevent recurrent febrile UTI is indicated in children with moderate to high grade (III-V) VUR (LE: 1b, GR: A). Surgical intervention may be used to treat VUR in the setting of recurrent febrile UTI because it has been shown to decrease the incidence of recurrent pyelonephritis (LE: 2, GR: B).

Management of Vesicoureteral Reflux: What Have We Learned Over the Last 20 Years?

Vesicoureteral reflux (VUR) is associated with increased risks of urinary tract infection, renal scarring and reflux nephropathy. We review advancements over the last two decades in our understanding and management of VUR. Over time, the condition may resolve spontaneously but it can persist for many years and bladder/bowel dysfunction is often involved. Some factors that increase the likelihood of persistence (e.g., high grade) also increase the risk of renal scarring. Voiding cystourethrography (VCUG) is generally considered the definitive method for diagnosing VUR, and helpful in determining the need for treatment. However, this procedure causes distress and radiation exposure. Therefore, strategies to reduce clinicians' reliance upon VCUG (e.g., after a VUR treatment procedure) have been developed. There are several options for managing patients with VUR. Observation is suitable only for patients at low risk of renal injury. Antibiotic prophylaxis can reduce the incidence of UTIs, but drawbacks such as antibiotic resistance and incomplete adherence mean that this option is not viable for long-term use. Long-term studies of endoscopic injection have helped us understand factors influencing use and the effectiveness of this procedure. Ureteral reimplantation is still performed commonly, and robot-assisted laparoscopic methods are gaining popularity. Over the last 20 years, there has been a shift toward more conservative management of VUR with an individualized, risk-based approach. For continued treatment improvement, better identification of children at risk of renal scarring, robust evidence regarding the available interventions, and an improved VUR grading system are needed.

Bladder/bowel dysfunction in pre-school children following febrile urinary tract infection in infancy.

BACKGROUND: An association between bladder-bowel dysfunction (BBD) and urinary tract infection (UTI) is well-known. However, a question less explored is whether children with UTI early in life also have increased prevalence of BBD after they are toilet-trained. In this study, consecutively selected children with pyelonephritis during their first year of life were assessed for BBD at pre-school age. METHODS: Ninety-two children (51 boys) hospitalized due to pyelonephritis during their first year of life were assessed for BBD at median age 5.4 years. A validated BBD questionnaire, along with urine flow and residual volume measurements, was used for diagnosing BBD. During follow-up, the group was well-characterized regarding renal status, vesicoureteral reflux (VUR), and recurrent UTI. RESULTS: BBD was diagnosed in 35/92 (38%), of which the majority was sub-diagnosed with dysfunctional voiding (DV). There was a strong association between BBD and recurrent UTI during follow-up (p < 0.0001), but only a slight association with VUR status at presentation. Nevertheless, in the group with both BBD and VUR, recurrent UTI was four times higher (12/13, 92%) than in children who had neither VUR nor BBD (23%), (p = 0.0008). BBD was also associated with kidney damage (p = 0.017). CONCLUSION: In children with pyelonephritis during the first year of life, 38% had BBD at pre-school age, regardless of whether they had VUR or not. The study shows an important association between BBD and recurrent UTI, so an assessment of BBD is therefore recommended for pre-school children with UTI, especially when they have history of pyelonephritis during infancy.

Preoperative Bladder Bowel Dysfunction Is the Most Important Predictive Factor for Postoperative Urinary Retention After Robot-Assisted Laparoscopic Ureteral Reimplantation via An Extravesical Approach: A Multi-Center Study.

Introduction: Postoperative acute urinary retention (pAUR) is a known occurrence after robot-assisted laparoscopic ureteral reimplantation via an extravesical approach (RALUR-EV). We hypothesized that the risk factor of pAUR after RALUR-EV might be similar to that of pAUR after open reimplantation. We aimed at performing a retrospective multi-institutional study to evaluate the risk factors for pAUR after RALUR-EV. Materials and Methods: Perioperative data collected from two tertiary referral hospitals included demographics and perioperative variables such as bladder bowel dysfunction (BBD) status, vesicoureteral reflux (VUR) grade, and laterality. pAUR was defined as the need for urethral catheter replacement after removal of the initial postoperative catheter. Univariate and multivariate analyses were performed to identify risk factors for pAUR. Results: A total of 117 patients with 174 renal units from the 2 hospitals were enrolled in this study. The median age at the time of surgery was 5 (0.3-19) years. Bilateral RALUR-EV was performed in 57 (48.7%) cases. pAUR rate was 3.4% in all patients and 7.0% in 57 patients with bilateral VUR. All four cases of pAUR occurred after bilateral surgery. Univariate analysis showed age (p = 0.037), weight (p = 0.039), height (p = 0.040), and bilaterality (p = 0.037) as risk factors of pAUR. In a multivariate analysis, BBD was the only significant risk factor of pAUR (p = 0.037). Conclusion: Urinary retention after RALUR-EV occurred less frequently when compared with the previously reported open surgery series. pAUR was seen only in bilateral cases in our series. Preoperative history of BBD, but not male gender or length of surgical time, was the only risk factor of pAUR after RALUR-EV.

Bladder/bowel dysfunction at school age is seen in children with high-grade vesicoureteral reflux and lower urinary tract dysfunction in infancy.

AIM: In approximately one third of cases, congenital high-grade vesicoureteral reflux (VUR) diagnosed during infancy is seen together with lower urinary tract dysfunction (LUTD), characterised by a high-capacity bladder and incomplete emptying. In an earlier study, 20 of these infants were treated with clean intermittent catheterisation during a 3-year period and with surgical treatment of the VUR before catheterisation was ended. In the present study, bladder function was evaluated in these children at school age. METHODS: Bladder function was evaluated in the 20 children at a mean age of 7.3 years using a validated voiding-bowel questionnaire with scores (cut-off score 7) and a urine flow/residual study. RESULTS: Four children (20%) had a normal voiding function at follow-up, whereas 11 (55%) had a clear bladder/bowel dysfunction (scores 7-19) and five (25%) had a mild dysfunction (score 6). Ten (63%) of the children with any dysfunction were recognised as dysfunctional voiding. Recurrent febrile urinary tract infections were correlated with the scores of faecal questions (P = .041), but for total scores P = .058. CONCLUSION: The follow-up of bladder function in children at 7.3 years, diagnosed with high-grade VUR and LUTD in infancy, revealed bladder/bowel dysfunction of varying severity in the majority of cases.

Current Management of Urinary Tract Infection and Vesicoureteral Reflux.

Urinary tract infection (UTI) is defined as the growth of a significant number of microorganisms of a single species in the urine, in the presence of symptoms. Symptoms in young children are non-specific such as fever without focus; young infants may manifest with irritability, failure to thrive, jaundice, vomiting and diarrhea. Older children usually have symptoms of cystitis or pyelonephritis. Symptoms of cystitis are dysuria, frequency, new onset incontinence and malodorous urine while symptoms of pyelonephritis are high grade fever, flank pain and vomiting. Rapid urine testing by microscopy for pus cells, dipstick testing for leukocyte esterase and nitrite, and enhanced urinalysis are supportive tests. Urine culture samples should be collected with proper technique and results interpreted for significant growth accordingly. Antibiotic therapy for 7-14 d for complicated UTI and 3-4 d for uncomplicated UTI is adequate. Further evaluation is recommended clinically for bladder-bowel dysfunction and obvious anatomical defects and by imaging for vesicoureteral reflux (VUR), usually by micturating cystourethrography (MCU). Since MCU involves exposure to radiation and urethral catheterization, it is now reserved for children with parenchymal involvement or recurrent UTI. VUR is the backward flow of urine into one or both ureters. Clinical manifestations other than UTI include incidental diagnosis on antenatal ultrasonography. Reflux nephropathy, the renal scarring associated with VUR may manifest clinically as hypertension, proteinuria and renal failure. The management of VUR is primarily with antibiotic prophylaxis. Anatomical correction is indicated in case of breakthrough febrile UTI. No intervention has been shown to reduce renal scarring.

Urotherapy in the treatment of children and adolescents with bladder and bowel dysfunction: a systematic review / Uroterapia no tratamento de crianças e adolescentes com disfunção vesical e intestinal: revisão sistemática

ABSTRACT Objective: To identify and describe the protocols and clinical outcomes of urotherapy interventions in children and adolescents with bladder bowel dysfunction. Method: Systematic review carried out in June 2018 on Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL),Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library, and PsycInfo databases. Clinical trials and quasi-experimental studies carried out in the last ten years in children and/or adolescents with bladder and bowel symptoms and application of at least one component of urotherapy were included. Results: Thirteen clinical trials and one quasi-experimental study were included, with moderate methodological quality. The heterogeneity of the samples and of the methodological design of the articles prevented the performance of a meta-analysis. The descriptive analysis through simple percentages showed symptom reduction and improvement of uroflowmetry parameters. The identified urotherapy components were: educational guidance, water intake, caffeine reduction, adequate voiding position, pelvic floor training, programmed urination, and constipation control/management. Conclusion: This review indicates positive results in terms of symptom reduction and uroflowmetry parameter improvement with standard urotherapy as the first line of treatment for children and adolescents with bladder bowel dysfunction. It is recommended that future studies bring contributions regarding the frequency, number, and time of urotherapy consultations.

RESUMO Objetivo: Identificar e descrever os protocolos e desfechos clínicos das intervenções de uroterapia em crianças e adolescentes com disfunção vesical e intestinal. Método: Revisão sistemática realizada em junho de 2018 nas bases Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library e PsycInfo. Foram incluídos ensaios clínicos e estudos quase-experimentais dos últimos 10 anos, em crianças e/ou adolescentes com sintoma urinário e intestinal e aplicação de no mínimo um componente de uroterapia. Resultados: 13 ensaios clínicos e 1 estudo quase-experimental foram incluídos, sendo a qualidade metodológica moderada. A heterogeneidade da amostra e de delineamento metodológico dos artigos impediu a realização de meta-análise. A análise descritiva por meio de percentual simples demonstrou redução dos sintomas e melhora dos parâmetros de urofluxometria. Os componentes de uroterapia identificados foram: orientação educacional, ingestão hídrica, redução de cafeína, posicionamento adequado para eliminação, treinamento do assoalho pélvico, micção programada e controle/manejo da constipação. Conclusão: Esta revisão sinaliza resultados positivos em termos de redução de sintomas e melhora nos parâmetros de urofluxometria com aplicação de uroterapia padrão como primeira linha de tratamento nos casos de crianças e adolescentes com disfunção vesical e intestinal. Recomenda-se que estudos futuros tragam contribuições no que tange a frequência, número e tempo para as consultas de uroterapia.

Bladder and Bowel Dysfunction in Korean Children with Down Syndrome and Parental Quality of Life.

PURPOSE: Children with Down syndrome (DS) are more likely to experience bladder bowel dysfunction (BBD) than typically developing children, which could in turn have a serious effect on children with DS and on their parents and other family members. This study aimed to explore the prevalence of BBD in Korean children with DS and its effect on parental quality of life (QOL). DESIGN AND METHODS: To assess BBD and parental QOL, we used self-administered questionnaires (Dysfunctional Voiding Symptom Score [DVSS], Rome IV criteria, and World Health Organization Quality of Life scale [WHOQOL-BREF]) for parents of children with DS. We collected data from 86 parents between September and October 2017 through an online community website. RESULTS: DVSS was elevated in 26.7% of the children with DS. Specifically, 14% had daytime urinary incontinence, and 33.7% had functional constipation. Moreover, 18.6% of children had BBD according to the DVSS and Rome IV criteria. The sensitivity and specificity of DVSS to functional constipation was 55.17% and 87.72%, respectively. The BBD score and total parental QOL score were statistically correlated (r = 0.291, p = 0.007). CONCLUSIONS: Although children with DS are a high-risk group for BBD, their BBD symptoms are often overlooked because of their intellectual disability. Consequently, this could negatively affect children's and family's health and QOL in the long term. PRACTICE IMPLICATIONS: Health-care providers should reconsider a routine check-up of BBD in children with DS. If a child has BBD, health-care providers should consult a urologist to determine the appropriate diagnosis and intervention.

Emotional and behavioral problems in children and adolescents with lower urinary tract dysfunction: a population-based study.

BACKGROUND: An association has been found between lower urinary tract dysfunction (LUTD) and emotional and behavioral problems, particularly in cases of urinary incontinence. Other associated symptoms and the coexistence of functional constipation require further investigation. OBJECTIVE: To assess whether emotional and behavioral problems are more common in children and adolescents with LUTD. STUDY DESIGN: A multicenter, cross-sectional, population-based study conducted in public places. Parents answered questions on urinary and psychological symptoms in their children aged 5-14 years. Children/adolescents with neurological problems or anatomical urinary tract abnormalities were excluded. The Dysfunctional Voiding Scoring System was used for assessing urinary symptoms, the Rome III Diagnostic Criteria for evaluating bowel symptoms, and the Strengths and Difficulties Questionnaire (SDQ) for evaluating emotional and behavioral problems. RESULTS: Of the 806 children/adolescents included, 53% were female. The mean age was 9.1 ± 2.7 years. The prevalence of LUTD was 16.4%. Overall, 26.2% had abnormal scores in the overall SDQ scale, 29.2% in the emotional problems subscale, and 30% in the conduct problems subscale. Of the children with LUTD, 40.5% screened positive for emotional/behavioral problems, with a significant association being found for the overall SDQ scale (P < 0.001) and for the emotional problems (P < 0.001), conduct problems (P < 0.001), and hyperactivity (P = 0.037) subscales. Urinary urgency, urinary incontinence, and voiding postponement were significantly associated with a greater prevalence of abnormalities in the overall SDQ score (P = 0.05; P = 0.004, and P = 0.012, respectively). Bladder and bowel dysfunction was an aggravator of emotional and behavioral problems, with more intense symptoms, both in the overall SDQ scale and in the subscales. In the multivariate analysis, the factors independently associated with the presence of emotional and behavioral problems were LUTD (odds ratio [OR] = 1.91), constipation (OR = 1.7), studying in a government-funded school (OR = 2.2), and poor education of the head of the family (OR = 1.9). CONCLUSIONS: Children and adolescents with LUTD have more emotional and behavioral problems, with bladder and bowel dysfunction being an aggravating factor for this association.

Urotherapy in the treatment of children and adolescents with bladder and bowel dysfunction: a systematic review.

OBJECTIVE: To identify and describe the protocols and clinical outcomes of urotherapy interventions in children and adolescents with bladder bowel dysfunction. METHOD: Systematic review carried out in June 2018 on Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL),Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library, and PsycInfo databases. Clinical trials and quasi-experimental studies carried out in the last ten years in children and/or adolescents with bladder and bowel symptoms and application of at least one component of urotherapy were included. RESULTS: Thirteen clinical trials and one quasi-experimental study were included, with moderate methodological quality. The heterogeneity of the samples and of the methodological design of the articles prevented the performance of a meta-analysis. The descriptive analysis through simple percentages showed symptom reduction and improvement of uroflowmetry parameters. The identified urotherapy components were: educational guidance, water intake, caffeine reduction, adequate voiding position, pelvic floor training, programmed urination, and constipation control/management. CONCLUSION: This review indicates positive results in terms of symptom reduction and uroflowmetry parameter improvement with standard urotherapy as the first line of treatment for children and adolescents with bladder bowel dysfunction. It is recommended that future studies bring contributions regarding the frequency, number, and time of urotherapy consultations.

Microsurgical Excision of T12-L1 Pial Arteriovenous Malformation: 3-Dimensional Operative Video.

This 29-yr-old man presented with progressive paraparesis, sensory loss, allodynia, bowel, and bladder dysfunction for 9 mo, acutely exacerbated in the preceding 24 h. Magnetic resonance imaging scan showed multiple dilated vessels involving the thoracic cord. Spinal angiogram revealed a T12-L1 pial arteriovenous malformation (AVM)/arteriovenous fistula on the left side. It was fed by an L1 radicular artery that filled the anterior spinal artery, which in turn had multiple feeders to a pial AVM. Because of the supply from the anterior spinal artery with multiple feeders to the AVM, and the danger of infarction of the conus, embolization was not performed. He underwent T11-L1 laminectomy laterally to the pedicles and excision of AVM. There was one large arterialized vein in the midline that had a fistulous connection with an artery coursing up from inferiorly. Despite occlusion of this fistula, the vein was still arterialized. On further exploration, there was a large artery coming in to the subarachnoid space at the T11 level and coursing inferiorly, and entering the intradural pial AVM with a glomus of vessels located at the T12 level in the left anterolateral subpial aspect of the cord. This major artery as well as multiple smaller vessels going into it were cauterized and divided, and the AVM was totally excised. Postoperative angiogram showed complete excision of the nidus. At 1 mo follow-up, he had complete recovery of motor and bladder functions but bowel dysfunction persisted. He was independent for his daily activities. Informed consent was obtained from the patient prior to the surgery that included videotaping of the procedure and its distribution for educational purposes. All relevant patient identifiers have also been removed from the video and accompanying radiology slides.
