Abstract
PURPOSE We compared heart rate variability parameters between patients with spina bifida and a control group during urodynamic studies, with the goal of evaluating the autonomic nervous system dysfunction present in spina bifida. METHODS Continuous heart rate variability parameters were recorded during 3 successive periods (P0, the 2 minutes prior to the start of filling; P1, from the start of filling to the first desire to void; and P2, from P1 to the end of filling or the start of voiding). The control group consisted of children with vesicoureteral reflux who had undergone video-urodynamic studies. Our study included 11 patients with spina bifida and 9 control participants. RESULTS At baseline, patients with spina bifida exhibited lower values for the root mean square of successive differences in NN intervals, the percentage of successive R-R interval differences exceeding 50 msec relative to the total number of intervals, and high frequency (HF). In contrast, the low frequency (LF)/HF ratio was elevated in these patients (5.04 ± 4.75 vs. 0.67 ± 0.42, P = 0.014). During bladder filling, LF/HF values increased in the control group (P0, 0.67 ± 0.42; P1, 0.89 ± 0.34; P2, 1.21 ± 0.64; P = 0.018), while they declined in patients with spina bifida (P0, 5.04 ± 4.75; P1, 3.96 ± 4.35; P2, 3.26 ± 4.03; P < 0.001). The HF values were significantly elevated in children with spina bifida during bladder filling (P = 0.002). In the time domain, the standard deviations of all NN intervals were elevated only in the control group during bladder filling. Parasympathetic activity domains were reduced in the children with spina bifida at the initial assessment. CONCLUSION During the bladder filling phase, parasympathetic activity increased along with fixed sympathetic activity in the spina bifida group. In contrast, the control group exhibited a shift towards a sympathetic preponderance at the conclusion of bladder filling. These observations may be associated with the pathophysiology of neurogenic bladder in spina bifida.

A prospective cohort study of assisted bladder emptying following primary cloacal repair: The Children's National experience. J Pediatr Urol 2023; 19:371.e1-371.e11. [PMID: 37037763 DOI: 10.1016/j.jpurol.2023.03.017] [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: 11/07/2022] [Revised: 02/20/2023] [Accepted: 03/11/2023] [Indexed: 04/12/2023]
Abstract
INTRODUCTION/BACKGROUND Although the combination of bladder dysfunction and upper tract anomalies puts patient with cloaca at risk for renal disease, the rarity of this condition makes it difficult to study empirically. As a high-volume center, we uniquely capture bladder function outcomes following our growing number of cloacal repairs. OBJECTIVE 1) Describe the rates of incomplete bladder emptying following primary cloacal repair (at 2-3 months after repair and last follow up), and 2) identify clinical factors associated with assisted bladder emptying. STUDY DESIGN We performed a prospective cohort study of patients undergoing primary cloaca repair by our Children's National Colorectal Center team between 2020 and 2021. The primary outcome was assisted bladder emptying at 2-3 months postoperatively and last visit. Covariables included preoperative characteristics (cloacagram measurements), ARM complexity (moderate = common channel [CC] <3-cm, severe = CC ≥ 3-cm), vesicoureteral reflux (VUR) status, sacral ratio (good ≥0.7, intermediate 0.7-0.4, poor ≤0.4), spinal cord status, means of preoperative bladder emptying, and operative details (age at repair, repair type, & concomitant laparotomy). RESULTS Eighteen participants were eligible. A majority had moderate cloaca (78%), VUR (67%), spinal cord abnormalities (89%), and good sacral ratios (56%). Preoperatively, 10 patients were diapered for urine and 8 had assisted bladder emptying. Surgical repairs were performed at a median age of 8 months (range 4-46). Nine (50%) patients underwent urogenital separation (UGS), eight (44%) total urogenital mobilization, and 1 (6%) perineal sparing posterior sagittal anorectoplasty with introitoplasty. Exploratory laparotomy was performed in 7 (39%) patients. At 2-3 months, 7 patients were voiding and 11 required assisted bladder emptying. Median length of long-term follow up was 12 months (range 5-25), and 8 patients were voiding and 10 required assisted bladder emptying. Postoperative need for assisted bladder emptying was significantly associated with assisted bladder emptying preoperatively, a shorter urethra and increasing common channel length, UGS and exploratory laparotomy. Spinal cord imaging findings were not associated. DISCUSSION Bladder emptying following cloaca repair is likely a result of congenital function and surgical effects. Indeed, increasingly cloaca complexity requiring UGS and laparotomy was associated with both pre- and post-operative assisted bladder emptying. The lack of association with spinal cord imaging may reflect a divergence between anatomy and function. CONCLUSION Approximately half of patients required assisted bladder emptying in this study. Associated factors included urethral and common channel length, the need for assisted bladder emptying preoperatively, the type of surgical approach and additional laparotomy. Being diapered with seemingly normal voiding prior to surgery did not guarantee normal bladder function postoperatively.

Abstract
PURPOSE The goal of this study was to determine the degree of consensus in the management of spinal cord tethering (TC) in patients with anorectal malformation (ARM) in a large cohort of European pediatric centers. METHODS A survey was sent to pediatric surgeons (one per center) members of the ARM-Net Consortium. RESULTS Twenty-four (86%) from ten different countries completed the survey. Overall prevalence of TC was: 21% unknown, 46% below 15, and 29% between 15 and 30%. Ninety-six agreed on screening all patients for TC regardless the type of ARM and 79% start screening at birth. Responses varied in TC definition and diagnostic tools. Fifty percent of respondents prefer ultrasound (US), 21% indicate either US or magnetic resonance (MRI) based on a pre-defined risk of presenting TC, and 21% perform both. Discrepancy exists in complementary test: 82% carry out urodynamic studies (UDS) and only 37% perform somatosensory-evoked potentials (SSEP). Prophylactic untethering is performed in only two centers (8%). CONCLUSIONS Survey results support TC screening in all patients with ARM and conservative management of TC. There is discrepancy in the definition of TC, screening tools, and complementary test. Protocols should be developed to avoid such variability in management.

Abstract
AIM The aim of the study is to investigate the effectiveness of Peristeen retrograde continence enema (RCE) in the management of faecal incontinence in children with spina bifida. METHODS We identified a homogenous group of spina bifida patients in whom RCE was initiated (Jan 2006-July 2013). Confidential assessments included (i) Fecal Incontinence Quality Of Life (FIQOL), (ii) St Marks Faecal Incontinence score, (iii) Cleveland Clinic Constipation score and (iv) Neurogenic Bowel Dysfunction score. RESULTS Of 20 patients, 11 (mean age 14.5 ± 5.3 years) were male. Of 20 patients, nine were still using RCE (mean follow-up 4.1 years). Three patients ceased RCE within 10 days, six after 4-12 months and two after 36-48 months. Reasons for cessation included balloon difficulties (n = 4), procedure deemed too difficult (n = 4) and pain (n = 3). There were no differences between the groups in length of training time for technique, instillate fluid/volume used and time taken to perform RCE. There were no differences between the groups for quality of life, faecal incontinence or constipation scores. CONCLUSIONS We demonstrated a high rate of cessation with RCE in patients with spina bifida. This could not be explained by associated conditions, or by enema-related parameters. One possible explanation is the lack of ongoing outpatient support for the children and their families.

Abstract
OBJECTIVE The goal of this study was to determine the significance of spinal cord anomalies (SCAs) in patients with anorectal malformations (ARMs) by comparing the outcomes for bowel function, lower urinary tract symptoms (LUTS), and lower-limb neurological abnormalities to these outcomes in patients with similar ARMs and a normal spinal cord. METHODS The spinal cord MRI records of female patients treated for vestibular and perineal fistula (VF/PF) and male patients with rectourethral fistula (RUF) at a single center between 1983 and 2006 were reviewed. Bowel function and LUTS were assessed by questionnaire. Patients with extensive sacral anomalies or meningomyelocele were excluded. RESULTS Of 89 patients (median age 15 years, range 5-29 years), MRI was available in 90% (n = 80; 40 male patients with RUF), and 80% of patients returned the questionnaire (n = 64; 31 male patients with RUF). Spinal cord anomalies were found in 34%, comprising a filum terminale lipoma in 30%, low conus medullaris in 10%, and thoracolumbar syrinx in 6%. Bowel functional outcomes between patients with SCAs (n = 23) and those with a normal spinal cord (n = 41) were not significantly different for soiling (70% vs 63%), fecal accidents (43% vs 34%), and constipation (57% vs 39%; p = not significant for all). The LUTS, including urge (65% vs 54%), urge incontinence (39% vs 24%), stress incontinence (17% vs 22%), and straining (32% vs 29%) were also comparable between groups (p = not significant for all). No patients developed lower-limb neurological abnormalities. CONCLUSIONS The results suggest that the long-term functional outcomes for patients with SCAs who had VF/PF and RUF may not differ significantly from patients with the same type of ARMs and a normal spinal cord. The results favor a conservative approach to their management in the absence of abnormal neurological findings in the lower limbs.

Abstract
Cloacal malformations represent one of the most complex conditions among anorectal malformations. Urologic conditions occur with an increased frequency in cloaca patients compared to patients with other types of ARM. The morbidity of the upper and lower urinary tract dysfunction/malformations at times can be severe; manifested by urinary tract infection, lower urinary tract symptoms, urinary incontinence, chronic kidney disease, and even end stage renal disease. Long-term follow-up of patients with cloaca has described significant chronic kidney disease and end-stage renal disease. Whether this rate of chronic kidney disease is a function of intrinsic renal dysplasia or acquired renal injury from neurogenic bladder is currently unknown. However, it is well known that severe lower urinary tract dysfunction, no matter the etiology, poses significant risk to the upper tracts when untreated. Neonatal assessment of the urinary tract accompanied by early identification of abnormal structure and function is therefore fundamental to minimize the impact of any urologic condition on the child's overall health. Adequate management of any associated bladder dysfunction is essential to preserving renal function, minimizing risk of urinary tract infection, and potentially avoiding need for future reconstructive surgery. This article summarizes our institution's approach to the ongoing early urologic management in patients with cloaca.

Abstract
PURPOSE We evaluated changes in urodynamic parameters of patients with tethered cord syndrome after detethering surgery and investigated factors predicting long-term urological outcome based on a previously described urodynamic scoring system. MATERIALS AND METHODS A total of 148 patients with tethered cord syndrome underwent detethering surgery at our hospital between January 2005 and March 2011. Of these patients 44 with preoperative and postoperative urodynamic data and a minimum followup of 2 years were included. Urodynamic score was composed of 4 parameters, with the sum ranging from 0 (favorable) to a maximum score of 17 (unfavorable). RESULTS Mean ± SD age at surgery was 38.0 ± 77.2 months and followup was 57.2 ± 20.6 months. Preoperative symptoms were present in 24 patients. Total urodynamic score at 6 months postoperatively was higher than preoperatively (mean ± SD 5.61 ± 2.71 vs 4.43 ± 3.56, p = 0.033) and remained at a similar value during followup (5.88 ± 3.89). The 6-month postoperative total urodynamic score was significantly lower in the 23 patients with favorable urological outcomes than in those with unfavorable outcomes (3.87 ± 2.02 vs 7.52 ± 1.99, p <0.001), whereas the preoperative urodynamic scores did not differ between these groups. The difference in urodynamic scores between favorable and unfavorable outcome groups became more prominent with time. By regression analysis the total urodynamic score at 6-month followup was a predictor of urological symptoms at last followup (OR 2.763, 95% CI 1.514-5.043, p = 0.001). CONCLUSIONS Six-month postoperative urodynamic scores accurately predicted the presence of urological symptoms on long-term followup and may be an important predictor of long-term urological outcomes after detethering surgery.

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
PURPOSE Urodynamic studies in children have been performed with increasing frequency as the techniques, reproducibility and reliability of the testing have been refined in the last quarter century. Children of all ages and with a variety of comorbidities are now often referred for urodynamic testing to evaluate and understand the causes of incontinence and/or persistence of lower urinary tract symptoms, as well as to appropriately define and evaluate treatment regimens. MATERIALS AND METHODS We performed a MEDLINE® search for relevant articles on urinary tract dysfunction, neurogenic bladder and urodynamic studies in the pediatric population. We also included 3 major textbooks that addressed the subject matter. RESULTS We review the current indications for urodynamic studies in children with nonneurogenic and neurogenic bladder dysfunction. We summarize the components and techniques of the current practice of urodynamic studies in the pediatric population, and explain how to identify abnormal results. CONCLUSIONS The use of urodynamic studies in pediatrics has become almost mandatory for the effective management of severe or therapy resistant urinary tract abnormalities. This review may be used as a guideline for the appropriate application of urodynamics in this patient population.

Abstract
BACKGROUND/PURPOSE Anorectal malformations (ARM) are a spectrum of defects ranging from the very minor ones, with an excellent functional prognosis, to those that are more complex, often associated with other anomalies, difficult to manage and with a poor functional outcome. A significant number of these children suffer from fecal and urinary incontinence despite major advances in the management of ARM patients have significantly improved the quality of life. The role of sacrovertebral anomalies/dysraphism (SD) and neurospinal cord anomalies/dysraphism (ND) associated with ARM on the continence of these patients is still controversial. The authors made a review of their experience in a period of 5 years, focusing on the role of neurospinal cord anomalies in patients with ARM. MATERIALS At colorectal clinic of our department of pediatric surgery 215 patients who underwent a procedure of posterior sagittal anorectoplasty for ARM are followed-up in a multidisciplinary clinic. Among them 60 patients with either SD or ND were documented. In 37 patients the anomaly involved the spinal cord (ND). 12 of these 37 patients underwent neurosurgical treatment and 25 were managed conservatively. Data collected from their follow-up were analyzed and compared, focusing on their bowel and urinary continence. RESULTS All 37 patients acquired regular bowel movements with an appropriate bowel management according to Peña's protocols. Urinary incontinence required clean intermittent catheterization in four cases. None of the patients who did not receive neurosurgical treatment developed acute complications due to the progression of the neurospinal anomaly, like acute urinary retention, orthopedic and motility problems or acute hydrocephalus. From literature review we were unable to find good evidence that the presence of ND worsens the functional prognosis of patients with ARM. We were also unable to find convincing evidence to support the practice of prophylactic neurosurgical procedures. CONCLUSIONS The present study supports the theory that for ARM patients the prognosis in terms of continence depends mainly on the type of malformation and is not complicated by the association with ND. In our series neurosurgical treatments did not have any effect in improving the continence of ARM patients and a conservative management of ND did not expose the patients to the sequelae of progressive deterioration, reported elsewhere, requiring rescue neurosurgery. We believe that the correct practice of pediatric surgeons following-up ARM patients is a protocol which includes appropriate investigations to detect the presence of a SD or ND and, once these entities are detected, it is mandatory to manage the patient with a multidisciplinary team, where a conservative non-operative management is initially justified and advocated in the absence of neurosensorymotor symptoms.

Abstract
Anorectal malformations (ARMs) and Hirschsprung disease (HD) are the most common congenital colorectal defects in the newborn. The outcomes of HD and ARMs have improved significantly because of improved understanding of the pathologic anatomy and physiology of these defects and of the modern surgical techniques. Still, many patients suffer from defective bowel control even as adults. Some of these also have problems with urinary control and sexual functions. The functional problems are more pronounced in patients with ARMs. Compared with healthy people, both patients with ARMs and those with HD have limitations in their quality of life. Inferior quality of life is more common in patients with ARMs. There are very few published data on long-term outcome of adults with ARMs and HD. The effect of aging on the functional outcome and quality of life remains unclear, although some preliminary data suggest that the bowel function and quality of life may deteriorate with aging.

Abstract
BACKGROUND A tethered cord (TC) has been reported in as much as 50% of the patients affected by anorectal malformation (ARM). No guidelines for timing and modality of diagnosis and treatment have been established. We present the preliminary results of a multidisciplinary protocol carried out at our center. METHODS Seventy-four ARM patients underwent spinal magnetic resonance imaging (MRI). All TC patients underwent videourodynamic (UD), somatosensory-evoked potentials (SEPs), and neurological examination at baseline and, if normal, at 5 and 10 years of age. Conversely, when UD or SEP abnormalities were detected the follow-up was individually tailored at shorter time. RESULTS 25/74 patients had a neuroradiological TC (33.7%). Based on the results of UD, SEP, and neurological status, four patients were untethered, eight are possible candidates, nine are stable, and four were excluded because of incomplete data. DISCUSSION Tethered cord is frequent in ARM patients. Because neurological deficits secondary to TC can contribute to neurological disability, we recommend routine MRI examination and a multidisciplinary program of follow-up in cases of TC. Preliminary results suggest the combined use of SEPs and UD could represent a useful adjunct to clinical examination in patients in whom a "wait and see" approach is preferred to the prophylactic surgery.

Abstract
Anorectal malformations are common anomalies observed in neonates. Survival of these babies is currently achieved in most cases and improvements in operative technique, patient care, and better follow-up have led to improved functional results. A new, simplified classification system (Krickenbeck classification) and method of functional assessment has led to an improved understanding of these anomalies and has allowed for a better comparison of outcomes. Following successful anatomical repair and appropriate programs of bowel care, socially acceptable continence can be achieved in a majority of patients, especially those with an intact sacrum.

Abstract
Constipation is extremely common in the pediatric population; however, it is a symptom and not a disease. Organic causes of constipation include Hirschprung's disease, anorectal malformation, and spina bifida. This article also discusses constipation and urinary tract pathology and dysfunction. The function of the gastrointestinal and urinary tracts are intertwined, and this concept will assist the practitioner in managing patients accordingly. Children and adolescents who experience bowel dysfunction require patience and sensitive support from their health care providers so that they can live productive and emotionally healthy lives.

Abstract
A review of the various causes of neurologic impairment to the lower urinary tract in children was the aim of this presentation. The emphasis was on diagnosis, pathophysiology, and treatment that strive to maintain as normal a function as possible in order to achieve eventual urinary continence and health of the upper urinary tract. The latest principles based on the most up to date evidence are promulgated but with an eye towards historical prospective. The reader should gain an adequate understanding of various disorders that comprise this condition and feel comfortable with proposing options for management when faced with the responsibility of caring for an affected child.

Abstract
OBJECT Tethering of the spinal cord is a pathological fixation of the cord in the vertebral column that can result in neurogenic bladder dysfunction and other neurological problems. It occurs in patients with closed spinal dysraphisms and those in whom postoperative scarring develops following spina bifida closure procedures. The authors of this study sought to determine the effects of detethering on the urodynamic profile of children with a tethered cord. METHODS The authors retrospectively reviewed the records of children who underwent surgical release of a tethered cord at a single institution between 2001 and 2003. They identified 17 children (nine girls and eight boys) who had undergone both preoperative and postoperative urodynamic evaluation. Preoperatively, 10 (59%) of the children with a tethered cord had abnormal urodynamic study (UDS) results. Only two (20%) of these patients had urological symptoms. All seven patients with normal preoperative UDS results had normal UDS results after detethering. In addition, in five (50%) of the 10 children with abnormal preoperative UDS results, the postoperative UDS demonstrated improved or normal urodynamics. CONCLUSIONS Because more than half of the children who underwent detethering were found to have abnormal preoperative UDS results, preoperative urodynamic evaluation should be performed in all cases in which detethering is considered. With regard to voiding function, detethering is relatively safe for children with normal preoperative UDS results. In children with abnormal preoperative UDS results, detethering may lead to improvement or even normalization of voiding, especially if the procedure is performed prior to 1 year of age. Finally, children with anorectal anomalies and a tethered cord may represent a subset of patients who are particularly likely to experience urodynamic improvement after detethering.

Abstract
OBJECTIVE To evaluate the incidence, types and the effect on outcome of associated anomalies in neonates with anorectal malformations (ARM). METHODS This retrospective study was carried out on all neonates with ARM admitted to the neonatal surgical intensive care unit (NSICU) from 1998 through 2003. RESULTS Of the 754 neonates admitted to the NSICU during the study period of 6 years, there were 124 (16.4%) neonates with anorectal malformations. Of these 110 were included in the study. 73 % were male and 27% female. 86% of these were high ARM (HARM) while only 14% were low ARM (LARM). Associated anomalies were seen in 68% of patients. The incidence was 72% for HARM and 50% for LARM. The major associated anomalies consisted of esophageal (13%), gastrointestinal (GIT) (11%), genitourinary (GUT) (32%), skeletal (26%), cardiac (33%) and miscellaneous 26%. The overall survival rate was 84% (82% for HARM and 94% for LARM). The survival among those with associated esophageal anomalies was 43%, GIT 67%, GUT 80%, cardiac 61%, skeletal 76% and miscellaneous 79% respectively. This difference in survival was significant only for those with esophageal (p=0.004) and cardiac anomalies (p=0.0026). The survival rates among those with one, two or more than two organ systems involved with associated anomalies were 88%, 82% and 58% respectively. This difference was significant only for more than two organ systems involvement (p=0.003). CONCLUSION Associated anomalies are common in neonates with ARM, the incidence being similar for HARM and LARM. The survival depends upon the number and severity of associated anomalies both in patients with LARM and HARM. Neonates with more number of organ systems involved have a poorer survival specially when associated with esophageal and cardiac anomalies. All neonates with ARM merit a meticulous search for associated anomalies so that the management can be tailored for each baby.
