Abstract
INTRODUCTION AND BACKGROUND Recent medical advances, including closure of myelomeningocele defects, shunting of hydrocephalus, and focusing on renal preservation have led to many individuals with spina bifida (SB) living into adulthood. This has led to more individuals with SB transitioning their care from pediatric-based to adult-based care models. OBJECTIVE We seek to explore the process of transition, with a focus on difficulties in transitioning individuals with SB. Additionally, we explore new problems that arise during the period of transition related to sexual function and dysfunction. We also discuss some of the difficulties managing neurogenic bladder and the sequalae of their prior urologic surgeries. STUDY DESIGN Each of the authors was asked to provide a summary, based on current literature, to highlight the challenges faced in their area of expertise. CONCLUSIONS Transitioning care for individuals with SB is especially challenging due to associated neurocognitive deficits and neuropsychological functioning issues. Sexual function is an important component of transition that must be addressed in young adults with SB. Management of neurogenic bladder in adults with SB can be challenging due to the heterogeneity of the population and the sequelae of their prior urologic surgeries. The aim is to ensure that all individuals with SB receive appropriate, evidence-based care throughout their lifetime.

Abstract
INTRODUCTION Neurogenic detrusor overactivity (NDO) results in involuntary detrusor contractions during bladder filling or storage risking transmission of pressure to the upper urinary tracts and/or significant incontinence. The goals of bladder management in children with NDO prioritize the preservation of renal function, prevention of UTIs, and optimizing quality of life. First-line measures include intermittent catheterization and anticholinergic medication. However, when conservative measures fail, surgical intervention may be indicated. Historically, the next step was major reconstructive surgery to create a low-pressure urinary reservoir. The introduction of intravesical botulinum neurotoxin A (BoNT/A) for use in children in 2002 offered a less invasive option for management. However, its exact role is still evolving. AREAS COVERED This article summarizes the mechanism of action of BoNT/A for management of NDO and evaluates the current literature defining common practice and clinical efficacy in children with NDO. The findings of the recently completed phase III trial for intravesical onabotulinumtoxinA in children are discussed in detail. EXPERT OPINION As the first BoNT/A approved for use in children with NDO, onabotulinumtoxinA appears to be a safe and less invasive alternative to major reconstructive surgery. However, data defining appropriate patient selection and its role as a long-term treatment option continue to develop.

Abstract
PURPOSE This study aimed to analyze organ system-based causes and non-organ system-based mechanisms of death (COD, MOD) in people with myelomeningocele (MMC), comparing urological to other COD. METHODS A retrospective review was performed of 16 institutions in Canada/United States of non-random convenience sample of people with MMC (born > = 1972) using non-parametric statistics. RESULTS Of 293 deaths (89% shunted hydrocephalus), 12% occurred in infancy, 35% in childhood, and 53% in adulthood (documented COD: 74%). For 261 shunted individuals, leading COD were neurological (21%) and pulmonary (17%), and leading MOD were infections (34%, including shunt infections: 4%) and non-infectious shunt malfunctions (14%). For 32 unshunted individuals, leading COD were pulmonary (34%) and cardiovascular (13%), and leading MOD were infections (38%) and non-infectious pulmonary (16%). COD and MOD varied by shunt status and age (p < = 0.04), not ambulation or birthyear (p > = 0.16). Urology-related deaths (urosepsis, renal failure, hematuria, bladder perforation/cancer: 10%) were more likely in females (p = 0.01), independent of age, shunt, or ambulatory status (p > = 0.40). COD/MOD were independent of bladder augmentation (p = >0.11). Unexplained deaths while asleep (4%) were independent of age, shunt status, and epilepsy (p >= 0.47). CONCLUSION COD varied by shunt status. Leading MOD were infectious. Urology-related deaths (10%) were independent of shunt status; 26% of COD were unknown. Life-long multidisciplinary care and accurate mortality documentation are needed.

Age-based risk of end-stage kidney disease in patients with myelomeningocele. J Pediatr Urol 2022; 19:195.e1-195.e7. [PMID: 36628830 DOI: 10.1016/j.jpurol.2022.12.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 11/30/2022] [Accepted: 12/19/2022] [Indexed: 12/31/2022]
Abstract
OBJECTIVE We aimed to quantify end-stage kidney disease (ESKD) risk after infancy in individuals with myelomeningocele (MMC) followed by urology in the modern medical era and to assess if ESKD risk was higher after surgery related to a hostile bladder. METHODS We retrospectively reviewed patients with MMC followed by urology at our institution born ≥ 1972 (when clean intermittent catheterization was introduced) past 1 year of age (when mortality is highest, sometimes before establishing urology care). ESKD was defined as requiring permanent peritoneal/hemodialysis or renal transplantation. Early surgery related to hostile bladder included incontinent vesicostomy, bladder augmentation, detrusor Botulinum A toxin injection, ureteral reimplantation, or nephrectomy for recurrent urinary tract infections. Survival analysis and proportional hazards regression were used. Sensitivity analyses included: risk factor analysis with only vesicostomy, timing of surgery, including the entire population without minimal follow-up (n = 1054) and only patients with ≥ 5 years of follow-up (n = 925). RESULTS Overall, 1029 patients with MMC were followed for a median of 17.0 years (49% female, 76% shunted). Seven patients (0.7%) developed ESKD at a median 24.3 years old (5 hemodialysis, 1 peritoneal dialysis, 1 transplantation). On survival analysis, the ESKD risk was 0.3% at 20 years old and 2.1% at 30 years old (Figure). This was ∼100 times higher than the general population (0.003% by 21 years old, p < 0.001). Patients who underwent early surgery for hostile bladder had higher ESKD risk (HR 8.3, p = 0.001, 6% vs. 1.5% at 30 years). On exploratory analyses, gender, birth year, shunt status and wheelchair use were not associated with ESKD risk (p ≥ 0.16). Thirty-year ESKD risk was 10% after early vesicostomy vs. 1.4% among children without one (p = 0.001). Children undergoing bladder surgery between 1.5 and 5 years old had a higher risk of ESKD. No other statistically/clinically significant differences were noted. COMMENT Patients with MMC remain at risk of progressive renal damage throughout life. We relied on the final binary ESKD outcome to quantify this risk, rather than imprecise glomerular filtration rate formulas. Analysis was limited by few people developing ESKD, inconsistent documentation of early urodynamic findings and indications for bladder-related surgery. CONCLUSIONS While ESKD is relatively uncommon in the MMC population receiving routine urological care, affecting 2.1% of individuals in the first 3 decades, it is significantly higher than the general population. Children with poor bladder function are likely at high risk, underlining the need for routine urological care, particularly in adulthood.

Abstract
Common causes of pediatric ESRD are distinct from those seen in the adult population. In the pediatric population, the most common are congenital anomalies of the kidney and urinary tract (CAKUT), affecting approximately 30% of children with CKD. These structural anomalies often require coordinated care with the pediatric urology team to address voiding issues, bladder involvement, and the potential need for surgical intervention. For pediatric nephrologists and urologists, common CAKUT that are encountered include antenatal hydronephrosis, obstructive uropathies (eg, posterior urethral valves), and vesicoureteral reflux. As more pediatric patients with CAKUT, CKD, and ESRD transition to adult care, it is important for receiving adult nephrologists to understand the clinical presentation, natural history, and prognosis for these diagnoses. This review outlines the diagnosis and potential interventions for these conditions, including strategies to address bladder dysfunction that is often seen in children with CAKUT. A discussion of these management decisions (including surgical intervention) for CAKUT, which are quite common to pediatric nephrology and urology practices, may provide unique learning opportunities for adult nephrologists who lack familiarity with these pediatric conditions.

Abstract
INTRODUCTION Treatment of neuropathic bladder secondary to spina bifida is an ongoing challenge. Although different management strategies and protocols are available in the literature, reliance on expert opinion remains fundamental. A conservative approach can be utilized, but patients must be closely monitored throughout the management process. The objective of this study was to review the management and outcomes of neuropathic bladder in spina bifida by appraising long-term bladder and renal function in patients treated at a medical center utilizing a conservative management style. METHODS This is a single-center retrospective review of urology care for all spina bifida patients 5-19 years of age with a neuropathic bladder who attended follow-ups between April 2000 and April 2020. Only patients with more than 5 years of follow-up were included. Renal functions, continence and results of invasive video urodynamics (IUD) and any surgical interventions were recorded. RESULTS Seventy-one patients (mean age = 10.5 years) were identified after exclusions. Bladder compliance between first and last IUDs increased significantly (p = 0.0056). Anticholinergic treatment was started at the first outpatient appointment. Intravesical botulinum toxin injection was the second line treatment in ten patients. 94% of patients had an end fill pressure below 40 cm H2O in their last IUD. 82% were socially continent (dry or occasional damp patches) with or without catheterisations at the age of 11.5 years. One patient in the cohort had bladder augmentation. CONCLUSION The optimal management of neuropathic bladder secondary to spina bifida remains controversial. Bladder and renal functional outcomes can be improved with close monitoring and less invasive management.

Abstract
Objectives: To investigate the relationship between the defects and symptoms caused by myelomeningocele (MMC) and quality of life. Design: A cross-sectional questionnaire survey. Methods: The subjects were 52 parents of children with MMC. Structured questionnaires were used: the Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQLTM 4.0) and a Study-Specific Questionnaire (SSQ). Results: The overall PedsQLTM 4.0 score was 56.4 (SD ± 14.7). A strong, significant negative correlation was found between the children’s age and emotional functioning. Functioning in this area deteriorated with age by a mean of 1.5 points per year of age. Children with no hydrocephalus functioned significantly better than those with this defect in the physical, social, and school areas (p < 0.05). Foot deformities significantly (p = 0.033) adversely affected the children’s physical functioning. Living in a single-parent family had no statistically significant impact on functioning in any of the areas analyzed (p > 0.05). Conclusion: Understanding the QoL of children with MMC and identifying its determinants may help in planning interventions to minimize the adverse impact of the illness.

Abstract
Simple Summary Disorders of bladder function can result from congenital spinal cord developmental defects and can remain in a significant number of patients despite surgical improvements to repair the primary defect. We studied the ability of bladder wall muscle from such patients to contract, a function essential to void collected urine and avoid urinary tract infections and potential damage to the kidneys. Tissue was taken when patients were several years old, at the time of surgical operations to improve bladder function. This tissue would otherwise have been discarded and was collected with the full ethical approval and consent of parents or guardians. We found that the ability of the bladder wall samples to contract was impaired and was generally stiffer; both of which would make it more difficult for the bladder to void urine. These functional changes were associated with a replacement of muscle with connective tissue (fibrosis). The experiments provide a pathway to devise strategies that might improve bladder function in these patients through reversal of the intrinsic tissue pathways that increase fibrosis. Abstract Neurogenic lower urinary tract (NLUT) dysfunction in paediatric patients can arise after congenital or acquired conditions that affect bladder innervation. With some patients, urinary tract dysfunction remains and is more difficult to treat without understanding the pathophysiology. We measured in vitro detrusor smooth muscle function of samples from such bladders and any association with altered Wnt-signalling pathways that contribute to both foetal development and connective tissue deposition. A comparator group was tissue from children with normally functioning bladders. Nerve-mediated and agonist-induced contractile responses and passive stiffness were measured. Histology measured smooth muscle and connective tissue proportions, and multiplex immunohistochemistry recorded expression of protein targets associated with Wnt-signalling pathways. Detrusor from the NLUT group had reduced contractility and greater stiffness, associated with increased connective tissue content. Immunohistochemistry showed no major changes to Wnt-signalling components except down-regulation of c-Myc, a multifunctional regulator of gene transcription. NLUT is a diverse term for several diagnoses that disrupt bladder innervation. While we cannot speculate about the reasons for these pathophysiological changes, their recognition should guide research to understand their ultimate causes and develop strategies to attenuate and even reverse them. The role of changes to the Wnt-signalling pathways was minor.

Abstract
PURPOSE Kidney dysfunction in spina bifida is usually detected by low estimated glomerular filtration rate or ultrasound based hydronephrosis. We assessed the diagnostic test characteristics of hydronephrosis for detecting low estimated glomerular filtration rate, hypothesizing that hydronephrosis has low sensitivity compared to cystatin C based estimated glomerular filtration rate. MATERIALS AND METHODS We conducted a single center, retrospective cohort study, including patients with spina bifida from 2012-2017 with 2 kidneys and complete data needed to calculate estimated glomerular filtration rate via multiple pediatric (age 1-17.9 years) or adult (age ≥18 years) estimating equations. We evaluated the association of hydronephrosis status (high grade, low grade or none) with estimated glomerular filtration rate, adjusting for small kidney size and scarring, and calculated diagnostic test characteristics of hydronephrosis for low estimated glomerular filtration rate. RESULTS We analyzed 247 patients (176 children and 71 adults). Mean±SD age was 13.7±6.6 years, and 81% of patients had myelomeningocele. Hydronephrosis (77% low grade) was found in 35/176 children and 18/71 adults. Hydronephrosis was associated with low estimated glomerular filtration rate in stepwise fashion, independent of kidney size and scarring. However, across cystatin C based pediatric equations, any hydronephrosis (compared to none) had 23%-48% sensitivity, and high grade hydronephrosis (compared to none or low grade) had 4%-15% sensitivity for estimated glomerular filtration rate <90 ml/min/1.73 m2, which remained unchanged after excluding small kidneys and scarring. Across cystatin C based adult equations, any and high grade hydronephrosis had 55%-75% and 40%-100% sensitivity, respectively, for estimated glomerular filtration rate <90 ml/min/1.73 m2, although with wide confidence intervals. Specificity was higher with high grade vs any hydronephrosis. Sensitivities were higher for estimated glomerular filtration rate <60 ml/min/1.73 m2. CONCLUSIONS Hydronephrosis was associated with low estimated glomerular filtration rate but had poor sensitivity for cystatin C based estimated glomerular filtration rate <90 ml/min/1.73 m2, especially among children with spina bifida.

Variability in Kidney Function Estimates in Emerging Adults With Spina Bifida: Implications for Transitioning From Pediatric to Adult Care. Urology 2020; 148:306-313. [PMID: 33242556 DOI: 10.1016/j.urology.2020.10.050] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 10/05/2020] [Accepted: 10/08/2020] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To examine the variability of estimated glomerular filtration rate (eGFR) in emerging adults with spina bifida (SB) by comparing multiple equations across the transitional age period, hypothesizing that creatinine (Cr)-based equations show greater variability than cystatin-C (CysC)- or combination-based equations. METHODS A retrospective cohort study was performed from 2012 to 2017 at a multidisciplinary SB clinic. Emerging adults were defined as patients ages 18-28 years old. Four pediatric, 3 adult, and 3 averaged eGFR equations were considered. Cross-sectional variability in eGFR data was assessed using coefficients of variation, chronic kidney disease (CKD) stage classification, and pairwise percent relative difference in eGFR between analogous pediatric and adult equations based on included lab values. Longitudinal changes in eGFR over time were compared across equations using a covariance pattern model accounting for repeated measures. RESULTS Seventy-five emerging adults with SB (median age 21.8 years; 55% female; 83% with myelomeningocele) were included in cross-sectional analyses. Adult equations gave higher median eGFRs by 22%-27% and generally milder CKD stage classification than analogous pediatric equations. In longitudinal analyses (median follow-up of 22 months), all equations conferred negative eGFR changes over time (range -1.9 to -4.3 mL/min/1.73m2 per year) that were not significantly different. CONCLUSION In emerging adults with SB, adult equations demonstrated higher median eGFRs by 22%-27% compared to analogous pediatric equations, even with Cystatin-C, and generally downstaged CKD stage classification. The same eGFR equation should be used for serial kidney function monitoring in emerging adults with SB who transition care from pediatric to adult services.

Abstract
PURPOSE Chronic kidney disease affects 25% to 50% of patients with spina bifida. Guidelines recommend kidney function surveillance in these patients but practice patterns are unknown. Variations in kidney function surveillance were assessed in patients with spina bifida based on the hypothesis that the treating clinic and spina bifida type would be associated with kidney function surveillance. MATERIALS AND METHODS A retrospective cohort study was conducted of U.S. patients in the National Spina Bifida Patient Registry from 2013 to 2018. Followup was anchored at the 2013 visit. Participants with either an outcome event within 2 years of followup or more than 2 years of followup without an outcome event were included. Primary outcome was kidney function surveillance, defined as at least 1 renal ultrasound and serum creatinine within 2 years of followup. Primary exposures were clinic and spina bifida type, which were analyzed with covariates including sociodemographic and clinical characteristics in logistic regression models for their association with the outcome. Sensitivity analyses were performed using different kidney function surveillance definitions. RESULTS Of 8,351 patients 5,445 were included with a median followup of 3.0 years. Across 23 treating clinics kidney function surveillance rates averaged 62% (range 6% to 100%). In multivariable models kidney function surveillance was associated with treating clinic, younger patient age, functional lesion level, nonambulatory status and prior bladder augmentation. Treating clinic remained a significant predictor of kidney function surveillance in all sensitivity analyses. CONCLUSIONS Within the National Spina Bifida Patient Registry wide variation exists in practice of kidney function surveillance across treating clinics despite adjustment for key patient characteristics.

Abstract
PURPOSE Estimated glomerular filtration rate (eGFR) in the general population is stable in children after 2 years of age until adulthood. In the first three decades after age 18, eGFR decreases by 0.3-0.8 ml/min/1.73 m2/year. Little data exists regarding eGFR changes in the spina bifida (SB) population given variability in muscle mass. In the absence of a validated SB-specific eGFR formula, the performance of different eGFR formulas may vary. We performed a cross-sectional study (1) to determine trends in eGFR with increasing age in children and adults with SB and (2) to compare eGFRs calculated using different formulas. METHODS We retrospectively reviewed records of patients 2-50 years old with SB followed at our institution (2014-2019). We determined eGFR using four pediatric formulas (2-17 years: CKiDSCr, CKiDCys, CKiDSCr-Cys, ZappitelliSCr-Cys) and four adult formulas (18 + years: MDRDSCr, CKD-EPISCr, CKD-EPICys, CKD-EPISCr-Cys). One eGFR per patient was included (most recent eGFR for those with serial measurements). Patients were categorized as chronic kidney disease (CKD) stage 2 (eGFR 60-89) and Stage 3+ (<60). Non-parametric tests, linear regression, and Spearman's correlation were used for analysis. RESULTS Among 209 children with SB (median age 10.3 years), depending on the formula used, eGFR decreased by -0.7 to -1.8 ml/min/1.73 m2/year (CKiDCys, CKiDScr, p ≤ 0.001), remained stable (CKiDSCr-Cys, p = 0.41), or increased by +2.7/year (ZappitelliSCr-Cys, p < 0.001) (Figure). The proportion of children with CKD 2 or higher varied between formulas (11.5-58.9%, p < 0.001). Correlations between pediatric formulas were negligible to moderate. Comparing any two formulas, 12.0-65.6% of children were assigned a different CKD stage. Among 164 adults (median age 26.3), eGFR decreased for each formula (range: -1.3 to -2.2/year, p ≤ 0.01) (Figure). The proportion of adults with CKD 2 or higher varied between formulas (9.2-30.5%, p < 0.001). Correlations between adult formulas were moderate to very high. Comparing any two formulas, 8.5-26.8% of adults were assigned a different CKD stage. COMMENT We cannot reliably determine whether eGFR changed during childhood. Among adults, eGFR decreased with age for every formula evaluated at greater than twice the general population rate. Without a validated SB-specific eGFR formula, we are left with formulas providing different results. CONCLUSIONS Estimated GFR among adults with SB appears to deteriorate at a higher rate than in the general population. Due to lack of precision of accepted eGFR formulas in the SB population, this may be a real phenomenon, an artifact of inaccurate eGFR formulas, or both. A validated SB-specific eGFR formula is needed.

Assessment of health literacy in adolescents with spina bifida and their caregivers: a multi-institutional study. J Pediatr Urol 2020; 16:167.e1-167.e6. [PMID: 32037145 DOI: 10.1016/j.jpurol.2019.11.016] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Accepted: 11/25/2019] [Indexed: 10/25/2022]
Abstract
INTRODUCTION and Objective: Health literacy is defined as the ability to obtain, integrate, and appraise health-related knowledge. It is known to correlate with disparities in clinical outcomes in adults with chronic disease. Patients with spina bifida represent a potentially vulnerable cohort as they often have multiple comorbidities. The authors aimed to characterize health literacy in adolescent patients with spina bifida and their caregivers. STUDY DESIGN The Newest Vital Sign (NVS), a validated assessment of health literacy and numeracy, was administered to patients (aged ≥10 years) and caregivers in outpatient pediatric urology and multidisciplinary spina bifida clinics. Subjects not fluent in English or Spanish and those with cognitive delay were excluded. Survey responses and demographic information were analyzed and compared between the spina bifida and control groups. RESULTS Three hundred eleven caregivers (caregivers for patients with spina bifida: 185, caregivers for the controls: 126) and 84 adolescents (those with spina bifida: 46, controls: 38) completed the NVS. Although there was no difference in health literacy between caregivers (p = 0.98), adolescents with spina bifida demonstrated lower NVS scores (spina bifida 1 [0-3] vs. control 2 [2-4]; p = 0.02) (Figure). Health literacy of patients with spina bifida and controls increased with age (p = 0.002). Adjusting for age and gender, the odds of having limited literacy were 5.5 times higher in patients with spina bifida than in the controls (p = 0.004). Inadequate caregiver health literacy was associated with a lower education level (p < 0.001). DISCUSSION Spina bifida is among the most complex birth defects compatible with life and affects a multitude of systems. Although it is well established that limited health literacy in adults with chronic disease is associated with adverse outcomes, there are considerably fewer data in the pediatric population. The authors found that caregivers of patients with spina bifida exhibited health literacy and numeracy comparable with parents in the control group, despite lower education levels. In contrast, adolescents with spina bifida demonstrated poorer health literacy than the controls. Multidisciplinary care is necessary, given the medical complexity of spina bifida; therefore, impaired understanding of adults' own needs may pose a barrier to successful transition to their care and subsequent outcomes. CONCLUSIONS The majority of surveyed caregivers for patients with spina bifida exhibited adequate health literacy, especially those with some college education; however inadequate health literacy was more likely among adolescents with spina bifida when compared with the controls. Screening for health literacy may be useful to assess readiness for transition to more independent self-care among patients with spina bifida.

Abstract
OBJECTIVES To report on the prenatal ultrasonographic diagnosis of spina bifida (SB) and its natural history, treatment and long-term outcome in a large tertiary referral center. METHODS All cases of SB diagnosed between February 1980 and December 2015 in the Obstetric Prenatal Diagnosis Day Unit of the Obstetrics and Gynecology Department at the Catholic University of the Sacred Heart, Rome, were reviewed. All infants with an open defect were delivered by elective Cesarean section and underwent early repair of the spinal defect. A ventriculoperitoneal (VP) shunt and/or third ventriculostomy was performed when needed. Complete postnatal follow-up was carried out by our multidisciplinary team in the majority of cases. The cohort was analyzed in two groups: Group 1 included patients referred between February 1980 and December 1999; Group 2 included patients referred between January 2000 and December 2015. RESULTS There was a total of 222 cases of SB with a prenatal diagnosis rate of 94.6% (n = 210), with the majority of defects being meningomyeloceles (n = 142 (64.0%)), affecting the lumbosacral level (n = 110 (49.5%)) and being ≥ 2 cm in size (n = 163/195 (83.6%)). There were 174 (78.4%) live births, with more terminations in Group 2 (26.1%) than in Group 1 (10.8%; P = 0.003). Postnatal surgical repair was conducted in 157 cases (99.4% of eligible cases), with death of an infant who was operated on occurring more often in Group 1 (14.1%) than in Group 2 (4.2%; P = 0.03). VP shunt placement was required in 60.3% of infants operated on after January 2000. Long-term follow-up was available for 136 children (111 with open defects and 25 with closed defects). Infants born since 2000 with an open defect had normal ambulation or a mild defect in 50% of cases and normal or mild deficit of sphincter function in 37.8% of cases. An intelligence quotient of ≥ 70 was observed in the majority of children (81.4%; 35/43 cases). Worse motor function was associated with progressive prenatal ventriculomegaly, level of lesion and VP shunt placement. CONCLUSIONS We describe the prenatal diagnosis, natural history and long-term outcome of a large contemporary cohort of SB fetuses and infants. In an era of pioneering fetal surgical techniques for in-utero SB repair, it is important to acknowledge that advances in conventional neonatology and pediatric neurosurgery have allowed increased life expectancy and improved quality of life in patients with SB.

Abstract
OBJECTIVE To assess cut-off value of creatinine and glomerular filtration rate for augmentation cystoplasty (AC) in paediatric age-group. MATERIALS AND METHODS Data of all paediatric-patients (<18 years) with small capacity bladder, in whom AC was advised between 2005-2015 were reviewed. All patients were divided in two-groups, AC-group and control-group (without AC). Creatinine and e-GFR were assessed at the time of surgery, at 6 months and at last follow-up. Renal function deterioration was defined as increase in creatinine by ≥25% from baseline value or new-onset stage-3 CKD or worsening of CKD stage with pre-operative-CKD stage-3. ROCs were plotted using creatinine and e-GFR for AC. RESULTS A total of 94 patients with mean-age 8.9 years were included. The mean creatinine and e-GFR were 1.33mg/dL and 57.68mL/min respectively. Out of 94 patients, AC was performed in 45 patients and in the remaining 49 patients AC was not done (control-group), as they were not willing for the same. Baseline patient's characteristics were comparable in both Groups. 22 underwent gastro-cystoplasty (GC) and 25 underwent ileo-cystoplasty (IC). Decline in renal function was observed in 15 (33.3%) patients of AC-group and in 31 (63.3%) patients of control-group. Patients having creatinine ≥1.54mg/dL (P=0.004, sensitivity (S) 63.6% and specificity (s) 90.5%) at baseline and e-GFR ≤46mL/min (P=0.000, S=100% and s=85.7%) at the time of surgery had significantly increased probability of renal function deterioration on follow-up after AC. CONCLUSION e-GFR ≤46mL/min and creatinine ≥1.54mg/dL at time of surgery could serve as a predictor of renal function deterioration in AC in paediatric patients.

Abstract
Context: Spina bifida (SB) can lead to changes in body composition and bone mineral density (BMD) through diminished ambulation, renal impairment, and anticonvulsant medication. With increased life expectancy, diseases such as obesity and osteoporosis are emerging comorbidities in SB, with limited data to guide management. Objective: To examine the relationship between cardiometabolic factors, body composition, BMD, and minimal trauma fractures (MTFs) in adults with SB. Design: Retrospective cross-sectional study. Setting and Participants: Forty-nine adults with SB (median age, 32.7 years; interquartile range, 22.6 to 39.0) who had undergone dual-energy x-ray absorptiometry imaging at a single tertiary hospital from 2004 to 2015. Results: The mean body mass index was 31.7 ± 7.5 kg/m2; 26 (53.1%) were obese. Using age- and sex-matched fat percentiles from the National Health and Nutrition Examination Survey III, 62.5% had a total body percentage fat greater than the 95th percentile. Low bone mass (defined as a Z-score of ≤−2.0) was present in 21.9% at the L1 vertebra and in 35.1% at the femoral neck. Ten (20.4%) had a history of MTFs. A BMD or Z-score at L1, femoral neck, or total body site did not correlate with the occurrence of MTF. Fat mass was significantly and positively associated with BMD after adjustment for age, sex, and height and accounted for 18.6% of the variance in BMD (P = 0.005). The prevalence of metabolic comorbidities, such as hypertension (20.4%) and obstructive sleep apnea (16.3%), was high. Conclusions: Obesity and low BMD are common in young adults with SB. An increased fat mass correlated significantly with BMD. The prevalence of metabolic complications in patients with SB is increased and deserves further study.

[PMID: 28163084 DOI: 10.1016/j.urology.2016.12.052] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2016] [Revised: 11/02/2016] [Accepted: 12/03/2016] [Indexed: 12/20/2022]
Abstract
Over the last 5 decades, health-care advances have yielded quantum improvements in the life expectancy of individuals with congenital genitourinary conditions (CGCs), leading to a crisis of care. Many individuals with CGC enter adulthood unprepared to manage their condition. Pediatric CGC specialists lack training to manage adulthood-related health-care issues, whereas adult genitourinary specialists lack training within the context of CGCs. To address these challenges, the National Institutes of Diabetes and Digestive and Kidney Diseases convened individuals with CGCs and experts from a variety of fields to identify research needs to improve transitional urology care. This paper outlines identified research needs.

Abstract
UNLABELLED This study assessed the prevalence and types of fractures in spina bifida and examined risk factors for fracture. Fracture prevalence was highest in childhood and reduced in adolescence and young adulthood. The importance of maintaining mobility is highlighted by the increased risk of fracture in those who are non-ambulatory. INTRODUCTION The aims of this study are to study the prevalence and types of fractures according to age group in spina bifida and examine risk factors associated with fracture. METHODS This is a retrospective cohort study of 146 individuals with spina bifida aged 2 years or older who attended the paediatric or adult spina bifida multidisciplinary clinic at a single tertiary hospital. RESULTS Median age at which first fracture occurred was 7 years (interquartile range 4-13 years). Fracture rates in children (ages 2-10), adolescents (ages 11-18) and adults (age > 18) were 10.9/1000 (95 % confidence interval 5.9-18.3), 5.4/1000 (95 % CI 1.5-13.8) and 2.9/1000 (95 % CI 0.6-8.1) patient years respectively. Childhood fractures predominantly involved the distal femur and femoral shaft; these fractures were rarely seen in adulthood. Non-ambulatory status was associated with a 9.8 times higher risk of fracture compared with ambulatory patients (odds ratio 9.8, p = 0.016, 95 % CI 1.5-63.0). Relative risk of re-fracture was 3.1 (95 % CI 1.4-6.8). Urological intervention with intestinal segments was associated with renal calculi (p = 0.037) but neither was associated with fracture. CONCLUSIONS The risk of fracture is lower in adults compared with children with spina bifida. The predominant childhood fracture affects the distal femur, and immobility is the most significant risk factor for fracture. Clinical factors contributing to fracture risk need to be elucidated to enable selection of patients who require investigation and treatment of osteoporosis.

Abstract
Introduction To analyze the correlations of bladder management technique, ambulatory status and urologic reconstruction on quality of life (QOL) as affected by urinary symptoms in adult spina bifida (SB) patients. Material and methods Sixty–six adult SB patients completed the RAND 36–Item Health Survey (mSF–36) and Incontinence Quality of Life (I–QOL). Demographic information, history of urinary reconstruction, and bladder management techniques were reviewed and analyzed with respect to survey scores. Results Mean age of patients was 32.3 (SD ±7.2) years and 44 patients (66.7%) were female. Forty–five patients (68.2%) were mainly ambulatory, 21 (31.8%) use a wheelchair and 10 (15.2%) had urologic reconstruction, while 56 (83.3%) did not. Twelve patients (18.2%) void, 42 (63.6%) perform clean intermittent catheterization (CIC), 4 (6.1%) use an indwelling catheter, 3 (4.5%) have an ileal conduit (IC) and 5 (7.6%) mainly use diapers. Mean mSF–36 General Health score was 56.5 (SD ±22.9) and mean I–QOL Sum score was 50.9 (SD ±21.7), where lower scores reflect lower QOL. mSF–36 and I–QOL scores did not significantly correlate with bladder management technique, ambulatory status or urologic reconstruction. A correlation was noted between I–QOL scales and most mSF–36 scales (all p <0.02). Conclusions In our cohort study of adult SB patients, bladder management technique and urologic reconstruction did not correlate with urinary (I–QOL) or general health (mSF–36) domains, although I–QOL and mSF–36 scores correlated closely, suggesting urinary continence is significantly related to general QOL. However, we are unable to identify a single factor that improves either urinary or general QOL.

Abstract
OBJECTIVE Augmentation cystoplasty (AC) is a major surgery that can be associated with long-term morbidity. This study aimed to describe the cumulative incidence of outcomes and urologic procedures in a large cohort of children who underwent AC, identify significant sources of morbidity, and to evaluate baseline factors associated with outcomes of interest. METHODS Children≤18 years who underwent AC in the Pediatric Health Information System from 1999 to 2010 were included. All follow-up encounters up to June 2012 were included. Cumulative incidences for 15 outcomes and urologic procedures were calculated using non-informative censoring. Sensitivity analyses were performed to determine effect of censoring assumptions and including hospitals without complete datasets. As an exploratory analysis, baseline patient factors were evaluated for associations with outcomes and urologic procedures of interest using multivariable Cox proportional hazards models adjusted for clustering by hospital. RESULTS 2831 AC patients were identified. Based on cumulative incidence calculations and sensitivity analyses; the cumulative incidence ranges of outcomes and procedures at 1, 3, 5, and 10 years were calculated. Examples of 10-year cumulative incidence ranges are given for the following outcomes and procedures: bladder rupture (2.9-6.4%), small bowel obstruction (5.2-10.3%), bladder stones (13.3-36.0%), pyelonephritis (16.1-37.1%), cystolithopaxy (13.3-35.1%), and reaugmentation (5.2-13.4%). The development of chronic kidney disease was strongly associated with a diagnosis of lower urinary tract obstruction (HR 13.7; 95% CI 9.4-19.9). Bladder neck surgery and stoma creation at time of AC were associated with an increased hazard of bladder rupture (HR 1.9; 95% CI 1.1-3.3) and bladder stones (HR 1.4; 95% CI 1.1-1.8) respectively. CONCLUSIONS Outcomes of interest and urologic procedures after AC are common. Results from this large cohort can be used to counsel patients and families about expectations after AC. Pyelonephritis, chronic kidney disease, further reconstructive surgery, and calculus disease appear to cause significant morbidity. Collaborative efforts are needed to further reduce morbidity in this patient population.

Abstract
PURPOSE We describe the characteristics, treatments and survival of patients with spina bifida in whom end stage renal disease developed from 2004 through 2008 in the United States Renal Data System. MATERIALS AND METHODS We used ICD-9-CM code 741.* to identify individuals with spina bifida using hospital inpatient data from 1977 to 2010, and physician and facility claims from 2004 to 2008. We constructed a 5:1 comparison group of patients with end stage renal disease without spina bifida matched by age at first end stage renal disease service, gender and race/ethnicity. We assessed the risk of mortality and of renal transplantation while on dialysis using multivariate cause specific proportional hazards survival analysis. We also compared survival after the first renal transplant from the first end stage renal disease service to August 2011. RESULTS We identified 439 patients with end stage renal disease and spina bifida in whom end stage renal disease developed at an average younger age than in patients without spina bifida (41 vs 62 years, p <0.001) and in whom urological issues were the most common primary cause of end stage renal disease. Compared to patients with end stage renal disease without spina bifida those who had spina bifida showed a similar mortality hazard on dialysis and after transplantation. However, patients with end stage renal disease without spina bifida were more likely to undergo renal transplantation than patients with spina bifida (HR 1.51, 95% CI 1.13-2.03). Hospitalizations related to urinary tract infections were positively associated with the risk of death on dialysis in patients with end stage renal disease and spina bifida (HR 1.42, 95% CI 1.33-1.53). CONCLUSIONS Spina bifida was not associated with increased mortality in patients with end stage renal disease on dialysis or after renal transplantation. Proper urological and bladder management is imperative in patients with spina bifida, particularly in adults.

Abstract
PURPOSE Renal failure has been a leading cause of death for children with spina bifida. Although improvements in management have increased survival, current data on mortality are sparse. Bladder augmentation, a modern intervention to preserve renal function, carries risks of morbidity and mortality. We determined long-term mortality and causes of death in patients with spina bifida treated with bladder augmentation. MATERIALS AND METHODS We retrospectively reviewed the records of patients with spina bifida who underwent bladder augmentation between 1979 and 2013. Those born before 1972 or older than 21 years at augmentation were excluded. Demographic and surgical data were collected. Outcomes were obtained from medical records, death records and the Social Security Death Index. Fisher exact and Wilcoxon rank-sum tests and Kaplan-Meier plots were used for analysis. RESULTS Of 888 patients in our bladder reconstruction database 369 with spina bifida met inclusion criteria. Median followup was 10.8 years. A total of 28 deaths (7.6%) occurred. The leading causes of mortality were nonurological infections (ventriculoperitoneal shunt related, decubitus ulcer fasciitis, etc) and pulmonary disease. Two patients (0.5%) died of renal failure. No patient died of malignancy or bladder perforation. Patients with a ventriculoperitoneal shunt had a higher mortality rate than those without a shunt (8.9% vs 1.5%, p = 0.04). CONCLUSIONS Previously reported mortality rates of 50% to 60% in patients with spina bifida do not appear to apply in children who have undergone bladder augmentation. On long-term followup leading causes of death in patients with spina bifida after bladder augmentation were nonurological infections rather than complications associated with augmentation or renal failure.
