Characteristics and predictors of chronic kidney disease in children with myelomeningocele: a nationwide cohort study. Pediatr Nephrol 2024; 39:1509-1519. [PMID: 38040872 DOI: 10.1007/s00467-023-06212-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 10/06/2023] [Accepted: 10/18/2023] [Indexed: 12/03/2023]
Abstract
BACKGROUND Myelomeningocele (MMC) is highly prevalent in developing countries, and MMC-related neurogenic bladder is an important cause of childhood chronic kidney disease (CKD). This nationwide study aimed to evaluate demographic and clinical features of pediatric patients with MMC in Turkey and risk factors associated with CKD stage 5. METHODS Data from children aged 0-19 years old, living with MMC in 2022, were retrospectively collected from 27 pediatric nephrology centers. Patients > 1 year of age without pre-existing kidney abnormalities were divided into five groups according to eGFR; CKD stages 1-5. Patients on dialysis, kidney transplant recipients, and those with eGFR < 15 ml/min/1.73 m2 but not on kidney replacement therapy at time of study constituted the CKD stage 5 group. RESULTS A total of 911 (57.8% female) patients were enrolled, most of whom were expectantly managed. Stages 1-4 CKD were found in 34.3%, 4.2%, 4.1%, and 2.4%, respectively. CKD stage 5 was observed in 5.3% of patients at median 13 years old (range 2-18 years). Current age, age at first abnormal DMSA scan, moderate-to-severe trabeculated bladder on US and/or VCUG, and VUR history were independent risk factors for development of CKD stage 5 (OR 0.752; 95%; CI 0.658-0.859; p < 0.001; OR 1.187; 95% CI 1.031-1.367; p = 0.017; OR 10.031; 95% CI 2.210-45.544; p = 0.003; OR 2.722; 95% CI 1.215-6.102; p = 0.015, respectively). Only eight CKD stage 5 patients underwent surgery related to a hostile bladder between 1 and 15 years old. CONCLUSION MMC-related CKD is common in childhood in Turkey. A proactive approach to neurogenic bladder management and early protective surgery in selected cases where conservative treatment has failed should be implemented to prevent progressive kidney failure in the pediatric MMC population in our country.

Abstract
The average worldwide prevalence of neural tube defects (NTDs) is 1.0 per 1000 births. Its development is multifactorial due to genetic and non-genetic factors. Spina bifida (SB) is one of main representatives of NTD. The spinal cord lesion level is the main determinant of the level of paralysis, numbness, and difficulties with bladder/bowel functions. Myelomeningocele prenatal repair reduces hydrocephalus and hindbrain herniation and improves motor function. The severity of hydrocephalus is associated with poorer neurodevelopmental outcomes whether operated on prenatally or after birth. People with SB tend to have a lower IQ and cognitive difficulties. Early diagnosis, proactivity, and lifelong multidisciplinary follow-up are key protective issues. Invasive urological interventions should be considered in selected patients after failure of conservative treatment. Transition to adult care should be well planned as it is challenging. Health literacy is directly associated with success at transition. Sexuality and fertility should be addressed before/during puberty. Overall, the rates of fecal and urinary continence and skin breakdown increase with age, whereas the ability to ambulate declines with age. Bowel and urinary incontinence are independent predictors of lower health-related quality of life (HRQoL) in adults with SB. Bowel incontinence has negative impact on HRQoL regardless of frequency or amount. Long-term caregiver support should be offered at diagnosis. Survival at a mean of 50 years is poor, at 32%, due to central nervous system deaths, cancer, urological disease, and sepsis. Challenges to implementation of recommended practices exist, especially in low and middle-income countries.

Determination of tibial somatosensory evoked potentials predicts detrusor sphincter dyssynergia in children with neurogenic bladder dysfunction. Neurourol Urodyn 2023. [PMID: 37185999 DOI: 10.1002/nau.25185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 03/15/2023] [Accepted: 04/04/2023] [Indexed: 05/17/2023]
Abstract
INTRODUCTION Tibial somatosensory evoked potentials (SEP) are used to identify the neurological status and tethered cord (TC) in patients with spina bifida (SB). Its significance in contributing to the interpretation of urodynamics to determine bladder status is unknown. This study aimed to determine the correlation between SEP and urodynamics in children with SB. MATERIAL AND METHODS SEP and urodynamic results, for differential diagnosis of TC, were evaluated. SEP scores were correlated with urodynamic findings. SEP results were scored from 1 to 6, with 1, denoting a favorable score and 6, an unfavorable score. Age, gender, detrusor, and sphincter activities in urodynamics were noted. Results were analyzed using the χ2 test and logistic regression analysis. Receiver operating characteristic (ROC) curve was formed to get a valid threshold for the SEP score to predict the urodynamic condition. RESULTS There were 44 SB patients for whom SEP was done for differential diagnosis of TC. Fifteen patients who did not meet the inclusion criteria were excluded from the study. SB aperta was present in 17 patients and occulta in 12, respectively. The patients had a mean age of 6.6 ± 3.2 years. There were 13 boys and 16 girls. A strong correlation was found between high SEP scores and detrusor sphincter dyssynergia (p < 0.001). A SEP score over 3.5 was found to be 93% sensitive and 73% specific to predict this correlation. There was no relationship between detrusor activity and SEP scores (p = 0.18). DISCUSSION Tibial SEP is an important noninvasive adjunct tool for the diagnosis of TC in patients with SB. Urodynamic studies are the gold standard in the evaluation of bladder status in neurogenic bladder dysfunction due to SB. Detrusor sphincter dyssynergia may be regarded as a sign of severe spinal cord injury in these patients. CONCLUSION Our findings suggest that in children with neurogenic bladder, high SEP scores may predict the presence of detrusor sphincter dyssynergia but not the status of detrusor function while providing pathophysiological evidence for neural injury.

Why are pediatric urologists unable to predict renal deterioration using urodynamics? A focused narrative review of the shortcomings of the literature. J Pediatr Urol 2022; 18:493-498. [PMID: 35817657 DOI: 10.1016/j.jpurol.2022.05.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 04/29/2022] [Accepted: 05/19/2022] [Indexed: 11/22/2022]
Abstract
In this focused narrative review we set out to review the current literature addressing the utilization of UDS in patients with spina bifida (SB). We specifically analyzed 6 urodynamic parameters and their roles as predictors of upper tract deterioration in pediatric SB patients. The material available did not allow a systematic analysis or the usage of metanalysis methodology, due to the predominance of small retrospective cohorts, and high heterogeneity. We identified 10 retrospective chart reviews that met our study criteria. The results of each of these papers, as well as other studies deemed relevant to the discussion, are included in our narrative review of the literature. We summarize the current literature, offer explanations for divergences in opinion, and identify future research directions and emerging solutions with a focus on machine learning.

Abstract
OBJECTIVE To investigate the risk factors for recurrent urinary tract infection (UTI) in children with a neurogenic bladder (NB) managed by clean intermittent catheterization (CIC). METHODS Over a 5-year period, we retrospectively assessed the risk factors for recurrent UTIs in children (age 9-151 months) who had CIC. All patients were followed up for more than 12 months and had at least two clinic visits during the study period. Demographic, clinical, and urodynamic parameters were assessed. All data were compared between the recurrent UTI (>1.0 UTI/study-year) and episodic UTI (≤1.0 UTI/study-year) groups. RESULTS Of 327 patients, 79 (24.2%) had recurrent UTIs and 248 (75.8%) had episodic UTIs. Univariate and multivariate analyses showed that older age, lumbar level lesions, long duration of NB, presence of vesicoureteral reflux (VUR), increased bladder wall thickness (BWT), and low bladder compliance were the significant factors for recurrent UTIs. Bladder trabeculation was associated with recurrent UTIs on univariate analysis, but not on multivariate analysis. During the follow-up period, chronic renal insufficiency was diagnosed in 31 (39.2%) and 29 patients (11.7%) in the recurrent and episodic UTI groups (p<0.05), respectively. CONCLUSIONS These results suggest that older age, high level of spinal cord lesions, long duration of NB, VUR, increased BWT, and low bladder compliance may be directly associated with recurrent UTIs in children with NB. Children with NB might have higher susceptibility to chronic renal insufficiency after recurrent UTIs.

Abstract
OBJECTIVES To evaluate the efficacy, safety and tolerability of vibegron for the treatment of antimuscarinic-resistant neurogenic bladder dysfunction in patients with spina bifida. METHODS In this retrospective study, 15 patients with antimuscarinic-resistant neurogenic bladder dysfunction due to spina bifida underwent a video-urodynamic study before and during the administration of vibegron 50 mg once daily instead of antimuscarinic agents from February 2019 through April 2021. The video-urodynamic study was carried out to evaluate bladder compliance, maximum cystometric bladder capacity, detrusor overactivity, detrusor leak point pressure and vesicoureteral reflux before and >3 months after the beginning of vibegron administration. RESULTS Treatment with vibegron significantly improved bladder compliance and maximum cystometric bladder capacity compared with antimuscarinic agents, respectively (7.4 ± 4.2 vs 30.4 ± 48.2 mL/cmH2 O, P = 0.0001; 231.4 ± 81.2 vs 325.2 ± 106.5 mL, P = 0.0005). Detrusor overactivity did not change after the administration of vibegron. Bladder deformity, which was confirmed in 12 patients, improved in half of the patients after taking vibegron. Vesicoureteral reflux, which was confirmed in two patients, was extinguished after taking vibegron. Newly occurring adverse events were not observed, and all patients continued to take vibegron during the treatment period. CONCLUSIONS Favorable efficacy of vibegron for antimuscarinic-resistant neurogenic bladder dysfunction due to spina bifida was shown video-urodynamically without apparent adverse events. Vibegron is a favorable option for the treatment of antimuscarinic-resistant neurogenic bladder dysfunction in patients with spina bifida.

Abstract
INTRODUCTION Defective closure of the neural tube affects different systems and generates sequelae, such as neurogenic bladder (NB). Myelomeningocele (MMC) represents the most frequent and most severe cause of NB in children. Damage of the renal parenchyma in children with NB acquired in postnatal stages is preventable given adequate evaluation, follow-up and proactive management. The aim of this document is to update issues on medical management of neurogenic bladder in children. MATERIALS AND METHODS Five Pediatric Urologists joined a group of experts and reviewed all important issues on "Spina Bifida, Neurogenic Bladder in Children" and elaborated a draft of the document. All the members of the group focused on the same system of classification of the levels of evidence (GRADE system) in order to assess the literature and the recommendations. During the year 2020 the panel of experts has met virtually to review, discuss and write a consensus document. RESULTS AND DISCUSSION The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies. Clean intermittent catheterization (CIC) should be implemented during the first days of life, and antimuscarinic drugs should be indicated upon results of urodynamic studies. When the patient becomes refractory to first-line therapy, receptor-selective pharmacotherapy is available nowadays, which leads to a reduction in reconstructive procedures, such as augmentation cystoplasty.

Abstract
Background To describe the extent of renal disease in Ugandan children surviving at least ten years after spina bifida repair and to investigate risk factors for renal deterioration in this cohort. Patients and Methods Children who had undergone spina bifida repair at CURE Children's Hospital of Uganda between 2000 and 2004 were invited to attend interview, physical examination, renal tract ultrasound, and a blood test (creatinine). Medical records were retrospectively reviewed. The following were considered evidence of renal damage: elevated creatinine, hypertension, and ultrasound findings of hydronephrosis, scarring, and discrepancy in renal size >1cm. Female sex, previous UTI, neurological level, mobility, detrusor leak point pressure, and adherence with clean intermittent catheterisation (CIC) were investigated for association with evidence of renal damage. Results 65 of 68 children aged 10-14 completed the assessment. The majority (83%) reported incontinence. 17 children (26%) were performing CIC. One child had elevated creatinine. 25 children (38%) were hypertensive. There was a high prevalence of ultrasound abnormalities: hydronephrosis in 10 children (15%), scarring in 42 (64%), and >1cm size discrepancy in 28 (43%). No children with lesions at S1 or below had hydronephrosis (p = 0.025), but this group had comparable prevalence of renal size discrepancy, scarring, and hypertension to those children with higher lesions. Conclusions Incontinence, ultrasound abnormalities, and hypertension are highly prevalent in a cohort of Ugandan children with spina bifida, including those with low neurological lesions. These findings support the early and universal initiation of CIC with anticholinergic therapy in a low-income setting.

Abstract
BACKGROUND Baseline and interval dimercaptosuccinic acid (DMSA) scans and urodynamic (UD) studies are often obtained in infants and young children with spinal dysraphism (SD). OBJECTIVE To identify practical UD parameters which accurately stratify urologic risk young children with SD. STUDY DESIGN 130 expectantly managed infants/young children with SD and initial DMSA and UD before age 2 were reviewed. End fill pressure (EFP), bladder trabeculations, vesicoureteral reflux (VUR), initial volume (IV) drained at UD catheter placement, and detrusor pressure at initial volume (DPIV) were evaluated for association with subsequent febrile urinary tract infection (UTI), DMSA abnormalities, and early clean intermittent catheterization (CIC). A combination of factors to accurately stratify risk was sought. Groups were compared by log-rank test. The association of CIC and febrile UTI incidence was evaluated. RESULTS 31/130 patients developed DMSA abnormalities, 52/130 started early CIC, and 61/130 developed a febrile UTI with median follow-up of 3.8 years. Trabeculations, VUR, EFP ≥40 cm H2O, IV ≥50% estimated bladder capacity (EBC), and DPIV >10 cm H2O were associated with subsequent abnormal DMSA scan (p < 0.001). The best predictor was combination of trabeculation and/or VUR (p < 0.001) (Figure). Among patients who maintained a non-trabeculated bladder without VUR during follow-up, 0/51 developed DMSA abnormalities compared with 31/79 who developed one or both (p < 0.001). Patients with trabeculations and/or VUR were more likely to start early CIC (8/51 vs. 44/79; p < 0.001) and have febrile UTI (11/51 vs. 50/79; p < 0.001). In those with trabeculations, CIC was associated with decreased incidence of febrile UTI (incidence rate ratio (IRR) 0.5, 95% CI 0.3-0.9); in those without trabeculations, CIC was associated with increased incidence of febrile UTI (IRR 1.8, 95% CI 1.1-3.1). CONCLUSIONS VUR, bladder trabeculations, EFP ≥40 cm H20, IV ≥50% of EBC, and DPIV >10 cm H2O were associated with subsequent DMSA abnormalities in young children with SD managed expectantly. Many of these parameters were associated with febrile UTI and early CIC. The combination of trabeculations and/or VUR outperformed other UD parameters in identifying those high and low-risk for adverse urologic outcomes. Routine DMSA scan may have limited utility in patients with a non-trabeculated bladder without VUR, as none developed an abnormal DMSA. Most (71%) abnormal DMSAs were in patients with trabeculations and/or VUR following a febrile UTI. Given these findings and that incidence of febrile UTI may be lower in those with trabeculations while on CIC, patients with trabeculations and/or VUR should be managed aggressively to protect kidneys.

Abstract
AIM The main goals of neurogenic lower urinary tract dysfunction (NLUTD) management are preventing upper urinary tract damage (UUTD), improving continence, and quality of life. Here, we aimed to systematically assess all available evidence on urodynamics predicting UUTD in patients with NLUTD. METHODS A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement was performed in March 2017. Only neuro-urological patients assessed by urodynamics were included. Any outcome of upper urinary tract function were evaluated. RESULTS Forty-nine studies (1 randomized controlled trial, 9 prospective, and 39 retrospective case series) reported urodynamic data on 4930 neuro-urological patients. Of those, 2828 (98%) were spina bifida (SB) children. The total number of adults was 2044, mainly having spinal cord injury (SCI) (60%). A low bladder compliance was found in 568 (46.3%) and 341 (29.3%) of the paediatric and adult population, respectively. Hydronephrosis (HDN) was detected in 557 children (27.8%) in 19/28 studies and 178 adults (14.6%), mainly SCI, in 14/21 studies. Nine out of 30 multiple sclerosis (MS) patients affected by HDN (16.8%) showed low compliance in 4/14 studies. CONCLUSIONS Patients with SB and SCI have a higher risk of developing UUTD (mainly reported as HDN) compared to those with MS. Reduced compliance and high DLPP were major risk factors for UUTD. Although our findings clarify the mandatory role of urodynamics in the management of NLUTD, standardization and better implementation of assessments in daily practice may further improve outcomes of neuro-urological patients based on objective measurements, that is, urodynamics.

Abstract
PURPOSE Report urologic outcomes among newborns with spinal dysraphism managed within an expectant clean intermittent catheterization (CIC) program. METHODS Newborns were followed clinically and with serial ultrasound (US). Urodynamics (UD) and dimercaptosuccinic acid (DMSA) renal scan were obtained at 3-6 months, 1 year, 3 years, then as needed. Patients with initial evaluation after 6 months were excluded. RESULTS Median follow-up was 3.2 years. 11/102 began catheterization for continence (median 4.0 years) and 47/102 did not start CIC. Of these, 2/58 developed a DMSA abnormality. 44/102 began CIC early, often for elevated storage pressures and febrile urinary tract infection (UTI). Of these, 20/44 developed a DMSA abnormality including 9 who had abnormality detected prior to starting CIC. Being on CIC or starting immediately upon recognition of new hydronephrosis, reflux, elevated filling pressures, or febrile UTI was associated with lower chance of DMSA abnormalities (4/17, 24%) compared to delaying CIC (16/27, 60%) (p= 0.03). CONCLUSIONS CIC can be deferred until continence in select infants with a low risk of significant DMSA abnormality. However, immediate initiation of CIC upon recognition of risk factors is recommended as this was associated with fewer DMSA abnormalities than delaying CIC. Recommendations for expectantly-managed patients include close follow-up, serial US and UD, and prompt initiation of CIC upon recognition of new hydronephrosis, reflux, elevated storage pressures, or febrile UTIs.

Abstract
OBJECTIVE To identify risk factors for recurrent urinary tract infection (UTI) in patients who perform clean intermittent catheterization (CIC). METHODS A 6-year retrospective chart review of patients with spina bifida or tethered cord who perform clean intermittent catheterization (8 months to 58 years) was conducted. A strict case definition for UTI was applied, and per-subject UTI events, demographic, and clinical data were abstracted. Data were compared between groups defined by no or infrequent UTI (≤1.0 UTI/study year) and frequent UTI (>1.0 UTI/study year). RESULTS Of 194 total patients, 146 (75%) had no UTIs or infrequent UTIs, and 48 (25%) patients had frequent UTIs. On univariate analysis, only younger age and suprasacral cord lesions were associated with frequent UTIs (P = .002 and P = .007, respectively). Among the 128 patients with urodynamic studies, bladder capacity, compliance, detrusor overactivity, and detrusor leak point pressure were not associated with frequent UTI on univariate analysis. On multivariate analysis, increasing age was found to be associated with decreased odds of UTI by 7% per year (odds ratio 0.93, P = .016). CONCLUSION The risk of UTI among individuals with spina bifida or tethered cord declines with increasing age. Bladder function based on urodynamic parameters did not correlate with frequent UTIs.

Can We Further Improve the Quality of Nephro-Urological Care in Children with Myelomeningocele? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2016; 13:ijerph13090876. [PMID: 27598183 PMCID: PMC5036709 DOI: 10.3390/ijerph13090876] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2016] [Revised: 08/11/2016] [Accepted: 08/26/2016] [Indexed: 11/17/2022]
Abstract
Myelomeningocele (MMC) results from a failure of normal neural tube fusion in early fetal development. Retrospective, observational study of medical data of 54 children treated in Pediatric Nephrology and Urology Clinics for five years was performed. The following data were analyzed: serum creatinine, eGFR, urine analysis, renal scintigraphy (RS), renal ultrasound, and urodynamics. Mean age of studied population: 12.3 years, median of eGFR at the beginning and at the end of survey was 110.25 and 116.5 mL/min/1.73 m2 accordingly. Median of frequency of urinary tract infections (fUTI): 1.2 episodes/year. In 24 children: low-pressure, in 30 children: high-pressure bladder was noted. Vesicouretral reflux (VUR) was noted in 23 children (42.6%). fUTI were more common in high-grade VUR group. High-grade VURs were more common in group of patients with severe renal damage. At the end of the survey 11.1% children were qualified to higher stages of chronic kidney disease. Renal parenchyma damage progression in RS was noted in 22.2% children. Positive VUR history, febrile recurrent UTIs, bladder wall trabeculation, and older age of the patients constitute risk factors of abnormal renal scans. More than 2.0 febrile, symptomatic UTIs annually increase by 5.6-fold the risk of severe renal parenchyma damage after five years.

Abstract
AIMS The aim of this study was to determine the occurrence of renal cortical scarring and chronic kidney disease (CKD) in children with neurogenic bladder secondary to spina bifida (SB) managed at the Universiti Kebangsaan Malaysia Medical Centre. The secondary objective was to identify the clinical factors associated with these adverse outcomes. METHODS The medical records of 56 children managed from 1997 were available. Socio-demographic and clinical data for SB children managed for a minimum of 2 years (n = 45) were reviewed. This included age at referral, gender, ethnicity, duration of care, type of SB lesion, presence of vesico-ureteric reflux (VUR), symptomatic urinary tract infections, bladder trabeculation, catheterisations and renal function. RESULTS Forty-nine per cent of SB lesions were open myelomeningocoele, 40% were closed lesions and 11% were occult. Majority (96%) were at lumbar L3 or below. Twenty-nine children (64.5%) were referred before 6 months of age (mean15.8 months; range newborn to 125 months). Thirty-five (77.8%) had neurogenic bladder and 31(69%) had neurogenic bowel. Sixteen developed renal scarring and six, CKD. Late referral (≥6 months of age), small kidneys at referral, dilating VUR and bladder trabeculation were significant independent factors associated with scarring. On multivariate analysis, late referral (odds ratio (OR) 17.4; 95% confidence interval (CI) 1.26-238.7) and dilating VUR (OR 137.0; CI 6.4-2921.1) remained significant. CONCLUSION Prevention of renal scarring and CKD remains a challenge in Malaysia even with multidisciplinary proactive care of SB children. Early referrals and more stringent management strategies for dilating VUR are still required.

Abstract
Background Significant bacteriuria (SBU) and urinary tract infections (UTIs) are common in patients with spina bifida and neuropathic detrusor sphincter dysfunction. Laboratory agar plated culture is the gold standard to establish SBU. It has the disadvantage of diagnostic and subsequent therapeutic delay. Leukocyte esterase tests (LETs) and dip slides proved to be useful in the general populations to exclude SBU and UTI. The aim of this study was to evaluate the reliability of LET and dip slide in children with spina bifida without symptoms of UTI. The reliability in children with asymptomatic SBU was not studied before. Methods In one hundred and twelve children with spina bifida on clean intermittent catheterization LETs and dip slides were compared with laboratory cultures. Both tests and agar plated cultures were performed on catheterized urine samples. The hypothesis was that the home tests are as accurate as laboratory cultures. Results A SBU was found in 45 (40%) of the 112 laboratory cultures. A negative LET excluded SBU (negative predictive value 96%), while a positive LET had a positive predictive value of 72%. The false positive rate was 28%. Dip slide determination of bacterial growth had no added value, other than serving as transport medium. Conclusions In spina bifida children, leukocyte esterase testing can be used to exclude significant bacteriuria at home, while dip slide tests have no added value to diagnose or exclude significant bacteriuria.

Abstract
PURPOSE The objective of this ICCS standardization document is to report the initial diagnostic evaluation and subsequent work-up of children with neuropathic bladder dysfunction. MATERIALS AND METHODS Due to a paucity of level I or level II, "levels of evidence" publications, these recommendations are actually a compilation of best practices because they seem to be effective and reliable, although not with any control. RESULTS Throughout the document, the emphasis is on promoting early, comprehensive evaluation of lower urinary tract function that is thorough but with a minimum of unnecessary testing. This includes what tests to order, when to order them and what to do with the results. Some of the recommendations may not be practical in various worldwide locations but the suggested testing should be considered the ideal approach to completely diagnosing and then promulgating treatments based on the full knowledge of the condition and its effect on urinary tract function. Once the findings are delineated, those lower urinary tract patterns of dysfunction that put the kidneys at risk for deterioration, that are barriers to attaining eventual continence, and that have long-term consequence to the lower urinary track can be obviated by specific management recommendations. The indications and timing of investigations to achieve these objectives are clearly defined in each diagnostic category and during follow-up. RECOMMENDATIONS This document should be used as a basis for appropriate evaluation and timely surveillance of the various neuro-urologic conditions that affect children.

Abstract
OBJECTIVE The prevalence of progressive chronic kidney disease (CKD) in children and adults with spina bifida is considerable, rising, and entirely preventable. REMOVING THE CAUSE PREVENTION OF SPINA BIFIDA: The best prevention of CKD in spina bifida is prevention of spina bifida itself through strategies that include folate supplementation, ideally before pregnancy. THE CAUSE OF CKD Dysfunctional bladder outlet causes febrile Urinary Tract Infections (UTI), even with clean intermittent catheterization (CIC), and subsequent renal scarring. The development of secondary vesicoureteric reflux (VUR) increases the risk of renal scarring and CKD. FINDING THE IDEAL MARKER FOR MEASUREMENT OF RENAL FUNCTION IN SPINA BIFIDA Creatinine-based methods are insensitive because of low muscle mass and underdeveloped musculature in the legs. Only Cystatin C-based eGFR can reliably assess global renal function in these patients. However, unilateral renal damage requires nuclear medicine scans, such as (99m)Tc DMSA. (VIDEO)URODYNAMICS STUDIES (UDS): Early treatment is recommended based on UDS with anticholinergics, CIC, and antibiotic prophylaxis when indicated. Overnight catheter drainage, Botox, and eventually augmentation cystoplasty are required for poorly compliant bladders. A continent child or one rendered continent following surgery is at a higher risk of renal damage. CONCLUSION A multidisciplinary approach is required to reduce the burden of CKD in patients with spina bifida. The right tools have to be utilized to monitor these patients, particularly if recurrent UTIs occur. Cystatin C eGFR is preferred for monitoring renal damage in these patients, and (99m)Tc DMSA scans have to be used to detect unilateral renal scarring.

Abstract
Patients with spina bifida require longitudinal urological care as they transition from childhood to adolescence and then to adulthood. Issues important to urological health, such as protection of the upper tracts and prevention of incontinence, need vigilant follow-up throughout the patient's life. As the child ages, additional issues such as sexual functioning also become increasingly important for social integration. Despite this need for regular assessment, many adult patients with spina bifida lose coordinated urological care after leaving specialized pediatric spina bifida clinics. Consequently, urologists frequently encounter an adult patient with spina bifida in practice and they need to understand the basic urological treatment goals and potential complications for this population.

The introduction of clean intermittent catheterization (CIC) in 1972 and low-dose chemoprophylaxis (LDCP, antibiotic prophylaxis), anticholinergic medication and urological surgery in the mid-1980s has improved the long-term outcome of renal function in children with neurogenic bladder sphincter dysfunction (NBSD) due to spina bifida (SB). We have conducted a European survey of the protocols for diagnosing and treating urinary tract infections (UTIs) in these children, using a web-based questionnaire. The responses from 41 centers in 14 European countries confirm that although most centers have standardized protocols for treating UTIs, there is no consensus among European centers in terms of protocols for preventing, diagnosing and treating UTIs in children with NBSD and for CIC.

Abstract
PURPOSE (99m)Technetium dimercapto-succinic acid renal scans are ideal for demonstrating renal scarring in children with spina bifida. However, doubt persists about the need for routine application. We assessed the associations among abnormal (99m)technetium dimercapto-succinic acid renal scans, vesicoureteral reflux and urodynamic findings in patients with spina bifida during long-term followup. MATERIALS AND METHODS We retrospectively reviewed the records of 64 patients with spina bifida followed at our center. All patients were older than 10 years (mean 15.8, range 10 to 23). Dimercapto-succinic acid renal scans were considered abnormal with differential function of less than 40% or focal defects. Patient age, gender, previous febrile urinary tract infections, positive vesicoureteral reflux history, timing of clean intermittent catheterization initiation and the latest urodynamic findings were noted. Patients were grouped based on normal/abnormal scan results. Statistical analysis included univariate and multivariate regression analyses and chi-square tests. RESULTS A total of 16 patients (25%) had abnormal scans. Mean patient age, male-to-female ratio, leak point pressure, bladder compliance and timing of clean intermittent catheterization initiation did not differ between groups. Rates of previous febrile urinary tract infections differed significantly (11 of 16 in the abnormal group vs 9 of 48 in the normal group, p <0.01), as did positive reflux history (100% vs 31%, p <0.01). No patient with a negative reflux history had an abnormal dimercapto-succinic acid renal scan. Multivariate analysis identified previous febrile urinary tract infections as a significant risk factor for an abnormal scan. CONCLUSIONS A positive vesicoureteral reflux history and febrile urinary tract infections were associated with abnormal dimercapto-succinic acid renal scan in followup of patients older than 10 years with spina bifida. Thus, these factors are indicators of proactive evaluation of renal function using dimercapto-succinic acid renal scanning.
