Transabdominal ultrasound of rectal diameter in healthy infants: a prospective cohort study during the first year of life. J Paediatr Child Health 2023; 59:1021-1027. [PMID: 37249409 DOI: 10.1111/jpc.16447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 05/17/2023] [Accepted: 05/19/2023] [Indexed: 05/31/2023]
Abstract
AIM Transabdominal rectal ultrasound (TRU) is used to measure transverse rectal diameter (TRD) in order to diagnose functional constipation (FC) and megarectum, and to evaluate treatment. The proposed cut-off value is 3.0 cm. Currently, no standardised values exist for children below the age of 4. We used repeated TRUs to establish reference TRD values in healthy infants and to describe rectal diameter in infants with FC. METHODS This prospective observational cohort study enrolled healthy term babies from a maternity department. TRD measurements were taken at 2 and 12 months of age, and questionnaires completed in interviews helped diagnose FC according to Rome III criteria. RESULTS Two hundred TRUs were performed on 110 infants (62 males). In infants without FC anytime, the mean TRD at 2 months was 1.56 (SD 0.32) cm and at 12 months 1.78 (0.47) cm, while the 95th percentiles were 2.26 and 2.64 cm, respectively. In 77 infants with two TRUs, the mean increase was 0.21 cm (95% confidence interval: 0.099-0.318). Thirteen infants were diagnosed with FC during the study period. At 2 and 12 months of age, there was no difference in TRD between infants with and without FC. CONCLUSION TRD increased from 2 to 12 months. We suggest 2.3 cm as an upper limit for normal TRD at 2 months and 2.6 cm at 12 months. Infants diagnosed with FC did not have a greater TRD than infants without, either before or after treatment. Further studies are needed to evaluate the usefulness of TRU in infants with FC or megarectum.

Bowel habits in healthy infants and the prevalence of functional constipation, infant colic and infant dyschezia. Acta Paediatr 2023; 112:1341-1350. [PMID: 36855830 DOI: 10.1111/apa.16736] [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: 09/19/2022] [Revised: 01/18/2023] [Accepted: 02/27/2023] [Indexed: 03/02/2023]
Abstract
AIM During infancy bowel habits change. Most infants with gastrointestinal problems have a functional gastrointestinal disorder (FGID), a major reason for visiting paediatricians. This study aims to provide data on stool frequency and consistency during the first year, prevalence rates for functional constipation (FC) and to establish associations with relevant demographic data. The occurrence of infant colic (IC) and infant dyschezia (ID) was also reported. METHODS This prospective observational birth-cohort study enrolled 122 healthy full-term infants. Questionnaires were completed at 2 weeks and 2, 6 and 12 months. RESULTS Stool frequency decreased with age and consistency changed, with fewer runny stools. At 2 weeks, 24.3% had at least one of the studied FGID. FC was found in 2.6%-14.3% (up to 12 months), IC was found in 4.9%-3.4% (up to 2 months) and ID in 22.1%-3.9% (up to 6 months). Infants with an FGID had a lower weight and more healthcare visits than infants without. Breastfeeding and a high percentage of runny stools at 2 weeks of age decreased the odds of developing FC. CONCLUSION Data on bowel habits and the prevalence of FC, IC and ID are presented. FGID during infancy is common and affects children's well-being, while their families need support and advice.

Whole exome sequencing identifies KIF26B, LIFR and LAMC1 mutations in familial vesicoureteral reflux. PLoS One 2022; 17:e0277524. [PMID: 36417404 PMCID: PMC9683562 DOI: 10.1371/journal.pone.0277524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2022] [Accepted: 10/31/2022] [Indexed: 11/25/2022] Open
Abstract
Vesicoureteral reflux (VUR) is a common urological problem in children and its hereditary nature is well recognised. However, despite decades of research, the aetiological factors are poorly understood and the genetic background has been elucidated in only a minority of cases. To explore the molecular aetiology of primary hereditary VUR, we performed whole-exome sequencing in 13 large families with at least three affected cases. A large proportion of our study cohort had congenital renal hypodysplasia in addition to VUR. This high-throughput screening revealed 23 deleterious heterozygous variants in 19 candidate genes associated with VUR or nephrogenesis. Sanger sequencing and segregation analysis in the entire families confirmed the following findings in three genes in three families: frameshift LAMC1 variant and missense variants of KIF26B and LIFR genes. Rare variants were also found in SALL1, ROBO2 and UPK3A. These gene variants were present in individual cases but did not segregate with disease in families. In all, we demonstrate a likely causal gene variant in 23% of the families. Whole-exome sequencing technology in combination with a segregation study of the whole family is a useful tool when it comes to understanding pathogenesis and improving molecular diagnostics of this highly heterogeneous malformation.

Bowel and bladder function in infant toilet training (BABITT) - protocol for a randomized, two-armed intervention study. BMC Pediatr 2022; 22:294. [PMID: 35590259 PMCID: PMC9118841 DOI: 10.1186/s12887-022-03355-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2021] [Accepted: 05/11/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In the last decades, the average age for toilet training has increased in the western world. It is suggested that the postponed initiation of toilet training is a contributing factor to problems related to bowel and bladder control. Functional gastrointestinal and urinary tract disorders are prevalent in childhood, causing suffering in affected children and for their families, and consuming healthcare resources. To evaluate whether assisted infant toilet training can prevent functional gastrointestinal and urinary tract disorders in young children, we are conducting a randomized intervention study with a 4-year follow-up. METHODS This randomized two-armed intervention study will include 268 Swedish infants recruited at six child healthcare centers in Region Dalarna located in the central part of Sweden. The intervention entails parents being instructed and practicing assisted infant toilet training with their child. Children are randomized to start assisted infant toilet training at 0-2 months or at 9-11 months of age. The primary objective is to determine the efficacy of assisted infant toilet training initiated at 0-2 months on the prevalence of functional gastrointestinal disorders (defined as infant colic, infant dyschezia and/or functional constipation) up to the age of 9 months. Secondary objectives are to evaluate whether assisted toilet training initiated during the first year of life reduce the prevalence of functional gastrointestinal disorders (defined as functional constipation, gastrointestinal symptoms and/or stool toileting refusal) and urinary tract disorders (defined as bladder dysfunction and/or urinary tract infections) up to the age of 4 years. Furthermore, infant-to-mother attachment, parental stress, the toilet training process and overall parental experiences will be evaluated/explored. DISCUSSION This protocol article presents the rationale and design of a randomized two-armed intervention study that will determine the efficacy of assisted infant toilet training on functional gastrointestinal disorders up to the age of 9 months. Furthermore, the study will evaluate whether assisted infant toilet training during the first year of life can prevent functional gastrointestinal and urinary tract disorders in children up to 4 years of age. If effective, assisted infant toilet training could be recommended in child healthcare settings and new evidence-based guidelines on infant toilet training could be implemented. TRIAL REGISTRATION The study protocol was retrospectively registered at ClinicalTrials. gov ( NCT04082689 ), initial release June 12th, 2019).

Abstract
OBJECTIVES Functional gastrointestinal disorders (FGD) are common during early childhood. In severe defecation disorders, anorectal manometry (AM) is done to exclude aganglionosis. High-resolution anorectal manometry (HRAM) can probably improve diagnostics but normative data in infants are scarce. This study aims to provide HRAM data in healthy infants overall and in subgroups of infants with FGD, defined as functional constipation (FC), infant colic (IC), and infant dyschezia (ID) (ROME 3 criteria). METHODS This prospective observational cohort study enrolled healthy term infants, having HRAM at 2 and 6 months, using a water-perfused pediatric anorectal silicone catheter. Data were provided for presence of anorectal waves and recto anal inhibitory reflex (RAIR), volume needed to elicit RAIR and anal resting pressure (ARP). Questionnaires at 2 and 6 months identified subjects with FC, IC, and ID. RESULTS A total of 187 HRAM investigations were done in 107 infants, without any complications. Normal RAIR was found in all, at least on one occasion. Mean ARP increased between 2- and 6-month investigations in infants without FGD. No other differences in HRAM data could be seen between infants with or without an FGD. At 2 months FC, IC, and ID were seen (2%, 4%, and 17%), whereas at 6 months only FC and ID were seen (7% and 1%). CONCLUSION We can provide data on HRAM in infants at 2 and 6 months of age. When performing repeated HRAM in healthy infants, RAIR was found in all subjects. HRAM is safe, easy tolerable, and can be recommended in infants with or without FGD.

A genome‑wide scan to locate regions associated with familial vesicoureteral reflux. Exp Ther Med 2021; 23:92. [PMID: 34976134 PMCID: PMC8674978 DOI: 10.3892/etm.2021.11015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Accepted: 07/06/2021] [Indexed: 11/05/2022] Open
Abstract
Vesicoureteral reflux (VUR) is a congenital malformation carrying a high risk of recurrent urinary tract infections (UTI) and, at worst, chronic renal failure. Familial clustering implies a genetic etiology, but studies during the past few decades have demonstrated a causal gene variant in <10% of patients with VUR. The aim of the present study was to search for fully or partially shared ancestral haplotypes in 14 families from south-western Sweden with at least three affected members. High-density single nucleotide polymorphism microarray was used for genotyping prior to analysis with a compatibility matching method developed in-house, and the analysis of copy number variations (CNV). No single unique haplotype was revealed to be shared by the families, thereby excluding a common ancestry and founder mutations as a probable cause of VUR. After evaluation of haplotypes shared by subsets of families, a haplotype shared by nine families was found to be of particular interest. This haplotype, located at chromosomal region 4q21.21, harbours two tentative candidate genes (bone morphogenetic protein 3 and fibroblast growth factor 5), both expressed in metanephros and with known functions during nephrogenesis. As to CNV, only one family had a specific CNV shared by all affected members. This was a focal deletion at 5q31.1 including follistatin-like 4, a gene without a previous known connection to VUR. These data demonstrated the genetic heterogeneity of VUR and indicated that an interaction of environmental and genetic factors, including non-coding and epigenetic regulators, all contribute to the complexity of VUR.

Four-hour voiding observations detect neurogenic lower urinary tract dysfunction in neonates with anorectal malformation. J Pediatr Urol 2021; 17:76.e1-76.e9. [PMID: 33148455 DOI: 10.1016/j.jpurol.2020.10.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Revised: 09/05/2020] [Accepted: 10/13/2020] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Neurogenic lower urinary tract dysfunction (LUTD) has been reported in 20-50% of children with anorectal malformations (ARM). As neurogenic LUTD represents an inherent risk of renal deterioration and urinary tract infections, an early diagnosis is important. The gold standard for evaluating neurogenic LUTD involves invasive urodynamic testing but a useful addition should be an easy-to-perform, non-invasive method of screening. OBJECTIVE In this study, we evaluate non-invasive 4 h voiding observations as a screening method for neurogenic LUTD in ARM children. STUDY DESIGN Thirty-four patients with ARM, excluding those with perineal fistulas, were evaluated using both 4 h voiding observation and urodynamic testing before and after posterior sagittal anorectoplasty (PSARP) at median ages of 0.3 and 1.1 years. In the urodynamic assessment, the gold standard for neurogenic LUTD, nine children received the diagnosis, eight innate and one post-surgery. RESULTS Five boys with a high urethral fistula and anomalies of the spinal cord had urodynamically diagnosed neurogenic LUTD, a dysfunction also identified in the 4 h voiding observations. The pattern was characterised both by an increase in the number of voiding and the number of interrupted voiding, urinary leakage and elevated residual urine (Figure). In three girls with a vestibular fistula and tethered cord, an urodynamic investigation identified suspected mild neurogenic LUTD. In the voiding observations, an abnormal voiding pattern was not as obvious in the girls as in the five males. One girl with cloaca showed signs of postsurgical denervation damage, which was easily identified in the 4 h voiding observations (high capacity and elevated residual urine). DISCUSSION In the present study, gender differences in the severity of dysfunction reflected in the free voiding pattern in infants with ARM and neurogenic LUTD is probably the result of the different underlying causes of neurogenic LUTD in boys and girls. Boys with the condition have a congenital malformation of the caudal part of the spinal cord and girls a tethering of the cord. The most obvious limitation of the study was the low number of patients. Despite this, we consider the results worth reporting, since we found that results in the free voiding observations effectively confirmed what was established in the urodynamic investigations. CONCLUSION In pre-PSARP patients, 4 h voiding observations can be used to screen for severe neurogenic LUTD requiring attention and treatment. When post-surgical denervation is suspected, the voiding observation is also a good method for indicating the diagnosis.

Bladder/bowel dysfunction in pre-school children following febrile urinary tract infection in infancy. Pediatr Nephrol 2021; 36:1489-1497. [PMID: 33274398 PMCID: PMC8084797 DOI: 10.1007/s00467-020-04853-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Revised: 09/22/2020] [Accepted: 11/06/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND An association between bladder-bowel dysfunction (BBD) and urinary tract infection (UTI) is well-known. However, a question less explored is whether children with UTI early in life also have increased prevalence of BBD after they are toilet-trained. In this study, consecutively selected children with pyelonephritis during their first year of life were assessed for BBD at pre-school age. METHODS Ninety-two children (51 boys) hospitalized due to pyelonephritis during their first year of life were assessed for BBD at median age 5.4 years. A validated BBD questionnaire, along with urine flow and residual volume measurements, was used for diagnosing BBD. During follow-up, the group was well-characterized regarding renal status, vesicoureteral reflux (VUR), and recurrent UTI. RESULTS BBD was diagnosed in 35/92 (38%), of which the majority was sub-diagnosed with dysfunctional voiding (DV). There was a strong association between BBD and recurrent UTI during follow-up (p < 0.0001), but only a slight association with VUR status at presentation. Nevertheless, in the group with both BBD and VUR, recurrent UTI was four times higher (12/13, 92%) than in children who had neither VUR nor BBD (23%), (p = 0.0008). BBD was also associated with kidney damage (p = 0.017). CONCLUSION In children with pyelonephritis during the first year of life, 38% had BBD at pre-school age, regardless of whether they had VUR or not. The study shows an important association between BBD and recurrent UTI, so an assessment of BBD is therefore recommended for pre-school children with UTI, especially when they have history of pyelonephritis during infancy.

Urological results and patient satisfaction in adolescents after surgery for proximal hypospadias in childhood. J Pediatr Urol 2020; 16:660.e1-660.e8.

Abstract
BACKGROUND Proximal hypospadias repair is associated with a considerable complication risk. Long-term follow-up is required to present realistic expectations in pre-operative counseling. OBJECTIVE To investigate adolescents after childhood surgery for proximal hypospadias in a prospective cohort study describing the urological outcome, complication rates and patient satisfaction with penile appearance. STUDY DESIGN 39 adolescents ≥14 years with penoscrotal to perineal hypospadias and primary urethroplasty (tubularized incised plate (TIP), preputial flap as Onlay or tubularized (Duckett)) from 1996 to 2005 at a single center were evaluated. The clinical assessment, at Md 16.5 years (14-25), included voiding history, genital examination including the Hypospadias Objective Scoring Evaluation (HOSE), uroflowmetry plus chart data from previous urinary flows and evaluation of patient satisfaction using the Penile Perception Score (PPS). RESULTS Twenty-nine patients with penoscrotal and 10 with scrotal/perineal hypospadias underwent surgery with TIP (N = 14), Onlay (N = 14) and Duckett (N = 11). Uroflows improved significantly compared with prepubertal maximal flows. Impaired flow rate (<10 mL/s) was found in 14% (5/36). Fifty-one percent (20/39) required reoperations, 29% (4/14) of TIP, 50% (7/14) of Onlay and 82% (9/11) of Duckett (p = 0.0062). Median penile length in adolescence was 8.7 cm (4.0-11.0). Forty-four percent (12/27) of patients were dissatisfied with penile length. Patients were 'satisfied' or 'very satisfied' with meatal position and shape despite HOSE for meatal position being 11% (4/38) distal, 76% (29/38) proximal glanular and 13% (5/38) coronal. TIP patients had more curvature at puberty than Duckett (p = 0.0062). Patients that had a decurvature procedure had shorter penile length (p = 0.019). DISCUSSION A high complication rate is previously described, predominantly within the first years. Our study shows 50% of reoperations were performed after >3 years, illustrating the need for long-term follow-up. Patient satisfaction with a deviant meatal position is rarely reported [1,2]. Our results support a conservative approach to an asymptomatic retracted meatus. Limitations of this descriptive study are the non-comparable groups and the retrospective data for correlation, impeding evaluation of prognostic outcome-factors. The shorter penile length found in patients after plication, and increased curvature after TIP, is therefore merely descriptive. However, the findings are in line with earlier publications suggesting limited use of TIP, and plication (recommending ventral lengthening instead) to avoid penile shortening and curvature in these cases [3-5]. CONCLUSIONS The urological long-term outcome after proximal hypospadias repair is good, although late reoperations are common. In adolescence, patients were dissatisfied with the short penile length but satisfied with meatal position, indicating that in proximal hypospadias, preserving penile length and correcting curvature are prioritized over a distal meatus.

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

Abstract
INTRODUCTION High-grade vesicoureteral reflux (VUR) in children is associated with recurrent urinary tract infection (UTI) and renal damage. Breakthrough UTI despite continuous antibiotic prophylaxis (CAP) during the first years of life is a matter of concern and evokes early intervention. We investigated whether early endoscopic treatment (ET) of VUR grade 4-5 can reduce the risk of UTI recurrence and renal scarring. MATERIALS AND METHODS This prospective, randomized, controlled, multicentre, 1-year follow-up trial comprised 77 infants, <8 months of age with VUR grade 4-5 (Table) randomized to CAP (n = 39) or ET (with prophylaxis until resolution) (n = 38). Voiding cystourethrogram, ultrasound, renal scintigraphy, and free voiding observation were performed at study entry and after 1 year. Parenchymal defects were seen in 67 (87%) children at entry, 39 (34 boys, 5 girls) of them characterized as generalized. At follow-up, renal deterioration (new scars or progress in old damaged area) and symptomatic UTIs were reported. RESULTS There were 27 recurrent febrile UTIs in 6 (16%) children in the ET group and in 10 (26%) in the CAP group (p = 0.43), in eight (36%) girls and eight (15%) boys (p = 0.039). Successful VUR outcome (VUR 0-2) was seen in 22 (59%) in the ET and eight (21%) in the CAP group (p = 0.0014). Multiple recurrences were only seen in patients with persistent dilating reflux at follow-up (p = 0.019). Deterioration on scintigraphy was seen in eight children (9 kidneys) with no difference between treatment groups (p = 0.48) or sex (p = 0.17). Renal deterioration was associated with high bladder capacity (BC) and large residual volume (PVR) at 1 year (p = 0.0092 and p = 0.041). Six of the eight children with renal deterioration had a recurrent UTI (p = 0.0032). Seven of nine renal units with deterioration were seen in children with persistent VUR 3-5 at follow-up. Univariable logistic regression identified female sex and high PVR as positive predictors for recurrent UTI (p = 0.039 and 0.034) and high PVR tended to predict renal deterioration (p = 0.053). DISCUSSION No differences between the treatment groups regarding recurrent UTI and renal deterioration could be found. Increased PVR and female sex were positive predictors for UTI recurrences. VUR grade at follow-up was correlated to UTI recurrence and renal deterioration. CONCLUSION This study did not show any difference between ET and CAP in reducing the risk of UTI recurrence or renal deterioration. The rate of VUR resolution was higher in the ET group and VUR grade at follow-up correlated with both UTI recurrence and renal deterioration.

Abstract
INTRODUCTION High-grade vesicoureteral reflux (VUR) in infants is associated with congenital renal abnormalities, recurrent UTI, and bladder dysfunction. Endoscopic treatment (ET) is a well-established method in children with low to moderate reflux grades, but there is a lack of randomised controlled trials regarding the use of ET versus continuous antibiotic prophylaxis in infants with high-grade VUR. OBJECTIVE This study aimed to determine whether high-grade VUR in infants can be treated with endoscopic injection and whether ET is superior to antibiotic prophylaxis in the treatment of VUR. MATERIALS AND METHODS This prospective, randomised, controlled, multicentre, 1-year follow-up trial comprised 77 infants (55 boys, 22 girls) <8 months of age with VUR grade 4-5 (n = 30/n = 47). Of the infants, 52 (68%) had bilateral VUR. Thirty-nine were randomised to antibiotic prophylaxis and 38 to ET (with prophylaxis until resolution). Voiding cystourethrogram, ultrasound, renal scintigraphy, and free voiding observation were performed at study entry and after 1 year to evaluate VUR grade, and renal and bladder function. RESULTS VUR grade ≤2 was seen in 22 (59%) infants in the endoscopy group and eight (21%) in the prophylaxis group at follow-up (p = 0.0014). The success rate in the endoscopy group was 100% in unilateral grade 4, falling to 31% in bilateral grade 5 (p = 0.0094). Correspondingly, the results in the prophylaxis group were 40% in grade 4 down to 0% in bilateral grade 5 (p = 0.037) (Table). Logistic regression analyses identified ET, VUR grade 4, unilaterality, and low residual urine at baseline as positive predictors of VUR down-grading to ≤2 (area under ROC curve 0.88). In four patients with reflux resolution after one injection, dilating reflux recurred at the 1-year follow-up. One patient had a UTI possibly related to ET. In our material four patients required re-implantation, of whom one was obstructive after injection. DISCUSSION The opportunity to offer even small infants with high-grade VUR an alternative, minimally invasive treatment option is a great advance in paediatric urology. In this high-risk group, bilateral VUR grade 5 stands out with its poor bladder function and low chance of resolution. The recurrence rate of dilating VUR after successful ET is consistent with previous studies. The limitations are the relatively small number of patients and the short follow-up. CONCLUSION High-grade VUR in infants can be treated with injection therapy and the resolution rate is higher than that of prophylaxis treatment. The complication rate is low and VUR grade 4, unilaterality, and low residual urine are favourable for the resolution and down-grading of VUR.

Abstract
OBJECTIVE This retrospective study aims to report treatment results in patients with long-gap esophageal atresia (LGEA), gross A + B type, and discuss the value of different clinical findings and physiological tests in the follow-up. METHODS This retrospective observational study comprises all patients with LGEA admitted to our department between 1995 and 2010. RESULTS A total of 16 patients were included. Their mean gestational age was 35(+2) weeks and their mean birth weight was 1,945 g (-2.5 standard deviation scores). No catch-up growth in height could be seen and they remained smaller than the average population during the study period. Gastrostomy was performed as the first surgical procedure. Overall, 11 of the 16 patients had a delayed primary anastomosis. Elongation of the distal esophageal segment was required in 3 of the 16 patients and a colonic interposition in 2 of the 16 patients. The median age at definitive surgery was 150 days. All the patients had gastroesophageal reflux after their definitive surgery. Three of the 16 patients required surgery due to aspiration and all 3 had a pathological lung clearance index (LCI) at multiple-breath washout (MBW). At the age of 1 or 7 years, the LCI was pathological in 4 of the 14 patients, and spirometry showed an obstruction in 9 of the 14 patients. CONCLUSION LGEA is a severe congenital malformation, with severe morbidity. No mortality was seen. MBW could be a useful tool for the early detection of progressive pulmonary damage.

Abstract
BACKGROUND Gastroesophageal reflux (GER) and dysphagia are common following repaired esophageal atresia (EA). The risk of esophagitis and Barrett esophagus is increased compared with the general population. As yet, the causes are not fully explained. PURPOSE The aim of this study was to investigate how GER, measured by pH multichannel intraluminal impedance (pH-MII), is correlated to the esophageal symptoms and histological findings. METHODS Twenty-nine adult subjects operated for EA in Gothenburg from 1968 to 1983 were evaluated with pH-MII, manometry, and gastroscopy. RESULTS pH-MII was performed in 15, manometry in 19, and gastroscopy in 24 subjects. Eleven subjects displayed pathological reflux parameters of any kind, mainly nonacid reflux (10/15). Dysphagia correlated to the number of weakly acidic reflux episodes. Lower esophageal sphincter (LES) incompetence, which correlated to a pathological number of acid reflux episodes (p = 0.012), was noted in 21/24 subjects, but the majority had a normal resting pressure. Esophagitis was present in 14/24, two of whom had Barrett esophagus. Histological changes correlated to the reflux index and the number of weakly acidic reflux episodes (p = 0.028 and 0.040) and tended to correlate to dysphagia (p = 0.052). CONCLUSION pH-MII adds further information when it comes to explaining what causes symptoms and esophageal histological changes in adults operated for EA.

Abstract
OBJECTIVE For many years, esophageal atresia (EA) has been curable by surgery. However, severe respiratory morbidity and gastroesophageal reflux (GER) symptoms remain a problem in many patients. The purpose of this study was to describe respiratory and esophageal morbidity, esophageal function, and lung function, including the small airways, in patients with the most common type of the malformation (EA with a distal fistula). METHODS The study comprised 26 children undergoing surgery for EA, who had performed respiratory and esophageal function studies at the age of 7 years in a follow-up program. The study design was retrospective analysis of both these 7-year functional investigations and esophageal and respiratory morbidity from birth to the age of 7 years, as documented in medical records. Pulmonary function was evaluated mainly by spirometry and multiple breath washout (MBW), whereas esophageal function was evaluated by 24-hour pH studies. RESULTS We found a high prevalence of both respiratory (69%) and esophageal (62%) morbidity between birth and 7 years among the EA children. Examination with MBW (peripheral airway function) revealed few abnormal results, whereas spirometry revealed high airway obstruction in half the children, which also correlated well with overall respiratory symptoms (p = 0.047), as well as recurrent pneumonias (p = 0.035). However, no association with GER symptoms was found. In addition, 46% of the children had GER according to pH measurements, which were correlated to clinical GER symptoms but not to respiratory symptoms. CONCLUSION This study confirms a high prevalence of respiratory and esophageal morbidity. In terms of respiratory function, the high proportion with a spirometric abnormality indicated an associated developmental delay/dysfunction in the central airways, whereas the peripheral airways appeared to have normal function at this age. Tracheomalacia may explain the spirometric abnormalities, but this need to be studied in more detail.

Abstract
PURPOSE An obstructive urinary flow pattern is frequently seen after tubularized incised plate urethroplasty for hypospadias. However, the significance of this finding has not been determined and long-term results are few. We describe postoperative long-term uroflowmetry results after puberty in males who underwent tubularized incised plate urethroplasty in childhood. MATERIALS AND METHODS A total of 126 boys underwent tubularized incised plate urethroplasty for distal penile to mid shaft hypospadias at Queen Silvia Children's Hospital in Gothenburg between 1999 and 2003. Of the patients 48 were toilet trained at surgery. We report on 40 patients who had data available at 2 and 12 months postoperatively, 7 years postoperatively and at puberty (median age 15.0 years, range 13.7 to 17.1). Of the patients 31 had distal and 9 had mid penile hypospadias. Clinical examination, urinary medical history, uroflowmetry and ultrasound measuring residual urine were performed. Maximum urinary flow was correlated to age and voided volume, using Miskolc nomograms for comparison of percentiles. RESULTS At 1 year postoperatively 15 boys (37.5%) had normal urinary flow (above 25th percentile), compared to 16 (40%) at 7 years and 38 (95%) at puberty (p <0.0001). Improvement was significant in patients with distal (p <0.0001) and mid penile hypospadias (p = 0.008), as well as in patients who did (p = 0.0078) and did not undergo intervention (p <0.0001). During followup 5 patients underwent meatotomy due to obstructive symptoms and 4 underwent dilation. Three of these 9 patients had lichen sclerosus. CONCLUSIONS There is great potential for normalization of urinary flow at puberty for boys with hypospadias treated with tubularized incised plate urethroplasty. Unless symptoms occur, a conservative approach seems preferable.

Radiological bladder characteristics in VCU for young children with high-grade VUR. J Pediatr Urol 2015; 11:30.e1-6.

Abstract
OBJECTIVES It has been suggested that infants with dilating vesicoureteral reflux (VUR) often have lower urinary tract (LUT) dysfunction. Signs such as high voiding pressure levels, low bladder capacity and dyscoordination at voiding have previously been thought to be indicative of dysfunction. However, these findings have also been recognised in healthy infants and are, thus, not specific to dysfunction in this age group. The urodynamic findings of interest for LUT dysfunction in children with high-grade VUR have been shown to be high bladder capacity with incomplete emptying, and often with overactivity during filling. Because the bladders in children with VUR are often only investigated with voiding cystourethrography (VCUG) and not urodynamics, the question has arisen as to whether some of the urodynamic findings indicating dysfunction can be recognised as radiological signs. The aim of the present study was to evaluate whether cystometric signs of LUT dysfunction in infants with high-grade VUR could be recognised in VCUG. MATERIALS AND METHODS One hundred and fifteen infants (80 boys) with Grades III-V VUR were included and investigated repeatedly with videocystometry (VCM) at a median age 6, 21 and 39 months. The sign looked for in the VCUG was bladder size (large, normal or small), according to the chosen levels in the bony pelvis. To validate the chosen levels for the different bladder sizes, bladder capacity data from a longitudinal study in healthy children were used. In addition, abnormalities in bladder wall/form and filling of the posterior urethra without voiding, as signs of bladder overactivity and detrusor-sphincter dyscoordination, were evaluated. RESULTS Bladder size was estimated on VCUG as large, normal or small, according to pelvic landmarks. Large bladder size was mainly seen at the second and third evaluations (64% and 46%), whereas small capacity was mainly seen during the first year (33%). Corresponding cystometric capacities (ml) showed a significant difference between the groups of small, normal and large bladder size. The cystometric capacities of large and small bladder size were also compared with bladder capacity in healthy controls, where large had significantly higher bladder capacity versus age (P = 0.0001) and small had significantly lower (P = 0.011) bladder capacity versus age than in the healthy controls. Bladder shape/wall pathology was mainly seen during the first year (42%), combined with small capacity, and correlated to overactive contractions during filling. Moreover, filling of the posterior urethra without voiding, indicating detrusor/sphincter dyscoordination at voiding, was quite common during the first year (33%), and then successively decreased. CONCLUSIONS The clinical implication from this study of small children with high-grade VUR was that a large bladder on VCUG was synonymous with a high-capacity bladder. According to earlier studies, this is a sign of LUT dysfunction in this age group and should therefore be an indicator for additional studies of bladder function. Overactive contractions could also be recognised in VCUG, but only at the infant evaluation, which should also be regarded as an indicator of LUT dysfunction. All other bladder VCUG signs mainly seen during early infancy were signs of immature bladder function and not a result of VUR dysfunction.

Effects of transcutaneous neuromodulation (TENS) on overactive bladder symptoms in children: a randomized controlled trial. J Pediatr Urol 2014; 10:1100-5. [PMID: 24881806 DOI: 10.1016/j.jpurol.2014.03.017] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2014] [Accepted: 03/30/2014] [Indexed: 12/25/2022]
Abstract
BACKGROUND The aim of the present study was to investigate whether addition of transcutaneous electrical nerve stimulation (TENS) treatment improves the results of standard urotherapy in children with overactive bladder (OAB) symptoms. MATERIAL AND METHODS Sixty-two children with symptoms of OAB and incontinence were included. The children were randomized either to standard urotherapy treatment alone or a combination of standard urotherapy and TENS. The effect variables were taken from a voiding-drinking diary: number of voiding, number of incontinence episodes, and maximum voided volume. RESULTS Both treatment groups had good treatment results, with no significant difference between the groups. In the standard treatment group 13/28 (46%) were completely dry and 11/28 (40%) had a decrease in incontinence episodes, compared to 16/24 (67%) and 3/24 (13%), respectively, in the standard+TENS group (p=0.303). The number of voiding decreased in two-thirds of the patients in both groups. However, maximal voided volume only increased in the standard treatment group. Subjectively 72% and 80% considered themselves significantly improved or free of symptoms. Previous treatment was registered in 15/55 (27%). All efficacy variables decreased in those with previous treatment, but with no difference between the standard and standard+TENS treatment groups. The only difference noted was when comparing the children without previous treatment in the groups: a significantly higher proportion were completely dry in the TENS group (12/18 [71%] versus 10/22 [48%], p=0.05). CONCLUSION Our results showed no significant difference overall in treatment response to OAB symptoms between urotherapy only and urotherapy+TENS, whereas a tendency to difference was found in children without previous treatment. Thus with good urotherapy support, TENS only seems to have marginal additional effects on OAB symptoms.

Megarectosigmoid in children with anorectal malformations: long term outcome after surgical or conservative treatment. J Pediatr Surg 2014; 49:564-9.

Abstract
PURPOSE Megarectosigmoid (MRS) is commonly seen in children with anorectal malformations (ARM) and contributes to the high incidence of constipation. Surgical resection has been advocated by some, whereas others propose intense bowel management as the treatment of choice. The aim of this study was to evaluate outcome of both bowel function and configuration after surgical or conservative treatment of MRS in ARM patients. MATERIALS AND METHODS The study included 79 patients with ARM, excluding perineal fistula, (48 boys, 31 girls) from 1986 to 2007. MRS was diagnosed at colostomy formation or contrast enema performed in the neonatal period. Early in the period, the majority of the patients were treated surgically, whereas in the late 1990 s, a conservative approach with intensified bowel treatment was implemented. Contrast enema and bowel function investigations were performed repeatedly during follow-up. RESULTS MRS, according to radiological criteria, was diagnosed in 26/79 (33%) of the ARM children. Bowel functional outcome was similar regardless of surgical or conservative treatment and comparable to function in ARM children with non-MRS. The radiological signs of rectal dilatation and elongation disappeared after surgical intervention, but normalisation of the rectosigmoidal configuration was also seen with age in the conservative group. CONCLUSIONS Bowel functional outcome in ARM children with MRS was similar after either surgical or conservative treatment during follow-up. The radiological signs of rectal dilatation and elongation disappeared also in the conservatively treated patients over time.

Abstract
PURPOSE Longitudinal follow-up of changes in bowel function in children with anorectal malformations (ARMs) with or without spinal cord pathology and neurogenic bladder dysfunction (NBD) as they grow. Another purpose was to identify predictors influencing bowel functional outcome. MATERIAL AND METHODS The study included 41 patients with ARM, excluding perineal fistula (21 boys and 20 girls). Bowel function was evaluated at ages 5, 10 and 15 years using a structured questionnaire and a three-week registration of number and time of bowel movements, episodes of fecal leakage and soiling. Additional bowel treatment with enemas and stool softeners and use of diapers were recorded. A group of 52 healthy boys and girls was used as control. RESULTS A successive improvement in functional outcome with age in children with ARM and normal spinal cord was seen with respect to continence, soiling and constipation. Continence was achieved earlier in girls than in boys (at 10 years: girls 80%, boys 36%). Soiling and constipation decreased with age both in grade and frequency (at 10 years low grade soiling: girls 53%, boys 64%). Boys with spinal cord malformation with NBD in combination with prostatic/bladder neck fistula (PRF/BNF) and sacral agenesis had the worst functional outcome with minimal possibility of improvement over time. Functional outcome in girls with NBD and tethered cord did not differ significantly from those without NBD and with a normal spinal cord. Psychosocial co-morbidity, neuropsychiatric disorders, developmental delay and megarectosigmoid were also risk factors impeding the functional outcome. CONCLUSION In the present study there was a successive improvement in bowel function during childhood and adolescence in ARM children, but they did not achieve the level of healthy children. NBD, spinal cord malformation, sacral malformation and PRF all were negative predictive factors for bowel score at 5 years.

Abstract
This review aims to provide researchers and clinicians involved with the adult lower urinary tract with background knowledge regarding the early development of bladder function and its most common disturbances in childhood. Bladder development begins in weeks 4-6 and the detrusor muscle is formed during weeks 9-12 of gestation. Higher CNS centres are involved in micturition at birth, and the infant usually wakes up, at least briefly, to void. Voiding during the first years of life is often incomplete, owing to detrusor-sphincter dyscoordination, but this disappears when bladder control is attained. Approximately 5-10% of 7-year-old children suffer from daytime incontinence and/or nocturnal enuresis, and a few per cent of them will not outgrow it. Daytime incontinence in childhood is usually attributable to detrusor overactivity, although it is unclear to what extent it is the detrusor or the micturition reflex per se that is overactive. Enuresis - nocturnal incontinence - is caused by either nocturnal polyuria and/or nocturnal detrusor overactivity, in both cases combined with high arousal thresholds. Bladder problems in childhood constitute a risk factor for the development or persistence of bladder problems in adulthood.

Abstract
OBJECTIVES To evaluate prophylaxis and endoscopic injection for children with dilating vesicoureteral reflux (VUR) compared to surveillance, regarding urinary tract infection (UTI) recurrence, new renal damage, VUR outcome, and impact of lower urinary tract (LUT) dysfunction on these outcomes. PATIENTS AND METHODS 203 children (128 girls and 75 boys), aged 1 to <2 years, with VUR grade III or IV were randomized to antibiotic prophylaxis (n = 69), endoscopic injection (n = 66) or surveillance (n = 68). Voiding cystourethrography, dimercaptosuccinic acid scintigraphy and optional LUT function assessment were performed before randomization and after 2 years. RESULTS There were 67 febrile UTIs in 42 girls and 8 in 7 boys (p = 0.0001). In girls, recurrence rate was 19% on prophylaxis, 23% with endoscopic treatment and 57% on surveillance (p = 0.0002). In boys, there was no difference between treatment groups. New damage was seen in 13 girls: 8 on surveillance, 5 in the endoscopic group and none on prophylaxis (p = 0.0155), and in 2 boys. In 13 children with no or non-dilating VUR after 1 injection, dilating VUR reappeared at the 2-year follow up. LUT dysfunction at follow up was associated with persistence of VUR. CONCLUSION In girls, prophylaxis reduced the rate of UTI recurrence and new renal damage, and endoscopic injection the rate of UTI recurrence. Boys did not benefit from active treatment.

Abstract
INTRODUCTION Dysphagia is not unusual following repair of esophageal atresia (EA). The lack of a uniform definition has led to a variance when it comes to reporting the prevalence of dysphagia among patients operated on for EA. Our aim is to estimate the occurrence and degree of dysphagia, using a numerical score with its statistical versatility independent of a specific definition. The results are used to find early risk factors of dysphagia within this patient group. The results are also used to see whether we can find a correlation between dysphagia and symptoms of gastroesophageal reflux (GER) and quality of life (QoL). METHODS 79 consecutive survivors operated on for EA in Gothenburg between 1968 and 1983 were located. Hospital charts were reviewed and patients received questionnaires on dysphagia, symptoms of GER and QoL. Dysphagia was measured by a numerical score, symptoms of GER were extracted using a predetermined questionnaire (GerdQ), and QoL was determined using the generic questionnaire SF-36. RESULTS 73 patients (92.4%) returned the questionnaires. In order to make the study group as homogeneous as possible with regard to the malformation we choose to study the 63 patients representing the vast majority: those with Gross type C. 36 patients (57%) had symptoms of dysphagia to varying degrees. We did not find any aggravating factors in their hospital charts nor did we find any correlation to the most recent demographics. There was a significant difference in dysphagia scores when we compared Gross type C to the often more complex type A (p<0.05). We did not find any correlation to heartburn but a strong correlation to regurgitation with an OR of 2.8 (95% CI: 1.2-6.6). The QoL was good for this patient group, and we did not find any correlation between QoL and the dysphagia score. CONCLUSIONS The dysphagia score provides easy-to-use results when it comes to evaluating the potential influence of dysphagia. Dysphagia is common within this patient group. Patients operated on for EA Gross type A seem to do worse when it comes to dysphagia. Regurgitation is associated with dysphagia, which could imply that GER is an aggravating factor. Further studies to support this finding will show whether there is a correlation between the dysphagia score and the results of 24-h pH-monitoring. If so, this could mean that treating GER might decrease dysphagia, at least in this patient group.

Abstract
OBJECTIVE To describe longitudinally the development of micturition patterns in children who are potty trained early. SUBJECTS AND METHODS Healthy children in Vietnam from newborn up to 1 year were investigated every 3 months. This included mapping of the micturition pattern through the 4-h micturition observation method. RESULTS Forty-seven children participated in all five investigations. At the ages of newborn, 3, 6, 9 and 12 months, 70%, 82%, 91%, 99% and 100% of the mothers, respectively, were potty training their children. Mean lowest bladder volume (voided volume + residual urine) triggering a micturition was 18 ml at the age of 2 weeks compared to 33 ml at 12 months. Post-void residual urine decreased according to age, and already at 9 months was less than 7 ml (mean 0.7 ml). CONCLUSIONS The dyscoordination between the sphincter and detrusor muscle seems to have already disappeared at the age of 9 months in infants who are potty trained very early. These findings suggest that potty training can be beneficial in small children with urinary tract infections or renal scars.

Abstract
PURPOSE We compared the rates of febrile urinary tract infection, kidney damage and reflux resolution in children with vesicoureteral reflux treated in 3 ways, including antibiotic prophylaxis, endoscopic therapy and surveillance with antibiotics only for symptomatic urinary tract infection. MATERIALS AND METHODS Children 1 to younger than 2 years with grade III-IV reflux were recruited into this prospective, open, randomized, controlled, multicenter study and followed for 2 years after randomization. The main study end points were recurrent febrile urinary tract infection, renal status on dimercapto-succinic acid scintigraphy and reflux status. Outcomes were analyzed by the intent to treat principle. RESULTS During a 6-year period 128 girls and 75 boys entered the study. In 96% of cases reflux was detected after urinary tract infection. The randomization procedure was successful and resulted in 3 groups matched for relevant factors. Recruitment was slower than anticipated but after patients were entered adherence to the protocol was good. Of the children 93% were followed for the intended 2 years without a treatment arm change. All except 2 patients completed 2-year followup scintigraphy. CONCLUSIONS Recruitment was difficult but a substantial number of children were entered and randomly assigned to 3 groups with similar basic characteristics. Good adherence to the protocol made it possible to address the central study questions.

Abstract
PURPOSE Reports concerning bladder dysfunction patterns in infants with high grade vesicoureteral reflux during the first year of life vs older children with reflux are contradictory. To describe the development of bladder function characteristics in children with congenital dilating reflux, we evaluated such infants urodynamically and followed them regularly for a 3-year period. MATERIALS AND METHODS A total of 89 males and 25 females with grade III to V dilating reflux were evaluated 3 times using videocystometry at mean ages of 6, 20 and 40 months. RESULTS Characteristics of the urodynamic pattern at 6 months could not be differentiated from normal patterns for that age, including low and normal bladder capacity, high voiding pressure levels, dyscoordination at voiding (80%) and overactivity during filling (60%). However, at 20 months the overall pattern was different, including increased bladder capacity and residual volume, normal voiding pressure, persistent overactivity during filling and dyscoordination at voiding. Bladder dysfunction was seen in 48 children (42%) at 20 months, of whom 34 primarily had high bladder capacity with incomplete emptying (dilated bladder dysfunction) and 14 had overactive bladder. Predictors for development of dilated bladder dysfunction at followup were high residual urine at 6-month examination and recurrent urinary tract infections. Recurrent infections were significantly correlated to high residual urine at all investigations and to detrusor overactivity at the 20-month examination. CONCLUSIONS Urodynamic patterns changed between the first and second year of life in patients with dilating reflux, from an immature pattern with high pressure levels to high capacity bladder with incomplete voiding. Therefore, bladder dysfunction, which was seen in 42% of patients, was only possible to diagnose after the first year of life and was mainly seen as high capacity bladder with incomplete voiding.

Impact of spinal cord malformation on bladder function in children with anorectal malformations. J Pediatr Surg 2009; 44:1778-85.

Abstract
PURPOSE Risk factors for the presence of neurogenic bladder dysfunction (NBD) in children born with high anorectal malformations (ARMs), were investigated, to identify the need for urodynamics in these patients. MATERIAL AND METHODS The study included 37 patients with high ARMs (21 boys and 16 girls). Bladder function was evaluated with urodynamics both before and after anorectoplasty (posterior sagittal anorectoplasty [PSARP]). All patients were investigated with spinal radiograph. Spinal ultrasound was performed in the neonatal period, and magnetic resonance imaging was added in case of abnormal ultrasound or urodynamics and in case of cloacal malformation. RESULTS In ARM patients with rectourethral and vestibular fistulas and cloacas, NBD was identified in 9 children (25%). The bladder dysfunction was innate in all cases except in one girl with cloaca, indicating that the risk of iatrogenic denervation seems minimal using the PSARP technique. All children with innate NBD had a spinal cord malformation either as spinal cord regression or tethering with or without a lipoma. Concerning vertebral status, almost all children with NBD had partial sacral agenesis. Abnormal perineal appearance was highly correlated to NBD in boys, especially in those with a spinal cord regression malformation. Innate NBD was not found in any child with normal spinal cord. CONCLUSION From these results, we suggest that spinal ultrasound and perineal inspection are used as screening procedures for NBD in children with ARM. Urodynamic investigation is recommended only when spinal cord anomalies or other signs indicative of NBD are present. In case of spinal cord malformation, repeated urodynamics during follow-up is mandatory because of the risk for developing tethered cord syndrome.

Abstract
OBJECTIVE It has been suggested that clean intermittent catheterization (CIC) during the teenage years is associated with poor motivation to comply with the treatment, recurrent urinary tract infections and epididymitis. The aim of this study was to identify the main problems and complications associated with self-CIC in a group of adolescents with no overt neurological problems. MATERIAL AND METHODS The medical records of 24 boys and girls aged >/=12 years on self-CIC with severe bladder dysfunction and intact perineal sensibility and motor function in the lower limbs were reviewed. The median age of the patients was 16.5 years (range 12-24 years) and they had been on CIC for a median of 11 years (range 2-16 years). RESULTS No urethral damage was reported. Of the 11 patients (46%) who had good CIC routines, two had cystitis and none had epididymitis. Thirteen patients (54%) reported a poor CIC regimen at a median age of 11.5 years (range 9-16 years). In this group, 10 had recurrent cystitis, five had pyelonephritis, four had increasing creatinine levels and three of nine boys had epididymitis. CONCLUSIONS One of the main problems associated with CIC during adolescence is poor compliance with the treatment. Epididymitis and recurrent urinary tract infections were seen more frequently in connection with poor CIC routines.

Abstract
The purpose with the present review was to characterise bladder function in healthy preterm and full-term infants from findings in studies using the four-hour voiding observation. Characteristics of the free voiding pattern were very similar in preterm and full-term infants. The frequency of voidings was once an hour, bladder volume inducing voiding varied, infants often woke up before voiding and the bladder was not completely emptied at every voiding. Furthermore, interrupted voidings interpreted as a detrusor-sphincter dyscoordination, were seen and were clearly an immature phenomenon since the frequency was high in the preterm infants and then decreased. Concluding these findings the voiding pattern seems to be immature early in life and there is distinct evidence for a connection to the CNS already in the preterm infant.

Abstract
The purpose with the present review was to describe what could be considered as normal urodynamic findings in neonates and infants. During the first months of life, urodynamics were characterised by small bladder capacity and high voiding pressure levels, the latter especially marked in male infants. Also dyscoordination at voiding was a common finding. However, detrusor overactivity (unstable contractions) during filling was uncommon in infants. Towards the end of infancy, findings became more in accordance with what is seen in older children. Concluding these findings concerning urodynamic pattern in early infancy high voiding pressure levels must be looked upon as normal and the same is true for intermittent increase in activity in the pelvic floor during voiding. However, instability during filling is rarely seen.

Is the mode of occurrence of vesicoureteral reflux correlated to bladder function and spontaneous resolution? J Pediatr Urol 2009; 5:170-7.

Abstract
PURPOSE To investigate whether mode of occurrence of vesicoureteral reflux (VUR), during micturition (M), during filling without increase in pressure (passive, P) or in response to an overactive contraction (OA), can be explained by differences in bladder function. Also, to study if the mode of occurrence of VUR can predict spontaneous resolution. MATERIALS AND METHODS There were 93 infants (68 boys and 25 girls) with VUR (grade III-V) included. Videocystometry was performed at median ages 5, 22 and 32 months registering grade and mode of reflux and bladder function characteristics. RESULTS Mode of occurrence of reflux changed with age. During infancy P, OA and M reflux comprised almost equal parts. At follow up, P reflux had increased and both OA and M reflux had decreased. This was partly due to a significantly higher probability of spontaneous resolution for M than P reflux, at 40 months (42 vs 18%). P and M reflux were significantly correlated to bladder function characteristics. P reflux was seen in children with high bladder capacity and occurred early in filling. Other predictors were higher age within the respective group and female sex. M reflux was correlated to lack of residual urine, low bladder capacity and absence of overactivity. Other indicators were male sex and low-grade reflux. CONCLUSIONS P and M reflux correlate to different bladder patterns: P with high bladder capacity and M with low bladder capacity and without signs of bladder dysfunction. M seems to be benign with a higher resolution rate.

Abstract
PURPOSE In children with spinal dysraphism such as myelomeningocele the relation between muscle mass and body composition varies considerably. Therefore, it is difficult to evaluate the relevance of renal function assessments done with serum creatinine. Since serum cystatin C has been suggested to be independent of body size and composition, this evaluation was compared to chromium(51) edetic acid clearance. MATERIALS AND METHODS Simultaneous measurements of cystatin C and chromium(51) edetic acid clearance were performed prospectively in 65 patients 2 to 19 years old with spinal dysraphism. RESULTS Cystatin C values were within the normal range in all patients, while chromium(51) edetic acid clearance was reduced in 10. A significant relation was seen. CONCLUSIONS Using chromium(51) edetic acid clearance as a gold standard, children with spinal dysraphism and slightly to moderately reduced renal function may remain undiagnosed if cystatin C is used for evaluation.

Abstract
PURPOSE We evaluated the rate of complications associated with catheterization and the risk of urethral lesions in girls with myelomeningocele treated with clean intermittent catheterization for a minimum of 10 years. MATERIALS AND METHODS We examined the medical records of 31 females with myelomeningocele followed from the start of clean intermittent catheterization until age 11 to 20 years. Catheterization had been performed for a median of 15 years (range 10 to 19). Altogether, catheterization was used for a total of 459 patient-years. Noncoated polyvinyl chloride catheters were used in all cases. Anticholinergic treatment was given during 176 of the patient-years. RESULTS Complications of catheterization were recorded in 13 patients on 20 occasions. Macroscopic hematuria was seen in 4 individuals. In 2 patients the hematuria was caused by urethral polyps that were cured by resection. Difficulties with catheterization occurred in 12 patients. The problems were solved by temporary use of lubrication or by other minor changes in management. There were no difficulties recorded after puberty. The risk of difficulties at catheterization doubled with the use of a Ch8 to Ch10 catheter compared to a Ch12 or larger catheter, and doubled during assisted clean intermittent catheterization compared to clean intermittent self-catheterization. CONCLUSIONS There were remarkably few problems associated with clean intermittent catheterization in these females with myelomeningocele, despite long treatment periods and use of noncoated polyvinyl chloride catheters. Clean intermittent self-catheterization and large size catheters were associated with few complications.

Abstract
PURPOSE We investigated whether the treatment of bladder dysfunction in infants with congenital high grade vesicoureteral reflux could influence the spontaneous resolution rate of the reflux and the number of recurrent urinary tract infections. MATERIALS AND METHODS A total of 115 infants with high grade vesicoureteral reflux were included in a followup study of bladder function and reflux resolution between 1993 and 1999. The present study deals with 20 of these infants with mainly grade V reflux, most of whom had recurrent urinary tract infections in combination with high post-void residual and high bladder capacity. Treatment with clean intermittent catheterization was instituted during infancy in these 20 patients and continued until a median age of 4 years. RESULTS Bladder capacity was high at presentation and at all followup investigations in the clean intermittent catheterization treated group. Moreover, residual urine was high at presentation and especially between ages 1 and 2 years. However, after bladder control was achieved this residual decreased and consisted mainly of reflux urine. In only 1 girl did reflux resolve spontaneously during the 4-year followup period. A total of 18 patients were treated surgically at the end of this period, and clean intermittent catheterization could be stopped a few months later in all but 2. Urinary tract infection recurrences were uncommon after the institution of treatment. CONCLUSIONS The treatment of bladder dysfunction characterized by a high capacity bladder with poor emptying in infants with congenital high grade reflux does not influence the rate of spontaneous resolution. On the other hand, the tendency toward recurrent urinary tract infections appears to decrease with treatment.

Abstract
PURPOSE The effect on bladder function of tethered spinal cord release in individuals with myelomeningocele differs in published studies, and the benefit has been the subject of debate. We studied the urodynamic findings in a consecutively treated population. MATERIALS AND METHODS Of 120 children born with myelomeningocele between 1986 and 1999, 20 underwent surgery for the tethered cord syndrome at a median age of 8 years (range 2 to 13). Time points for cystometry used for comparison were before symptoms at a median age of 20 months (range 9 to 106), a median of 5 months preoperatively (1 to 33) and at 12 months postoperatively (6 to 19). Severe bladder dysfunction was defined as basal pressure more than 40 and/or overactivity greater than 60 cm H2O, moderate dysfunction as basal pressure 20 to 40 and/or overactivity 20 to 60 cm H2O, and mild dysfunction as basal pressure less than 20 cm H2O. RESULTS Of the 20 patients who underwent untethering 7 had improvement to a milder dysfunctional level, while 1 deteriorated postoperatively. Six patients experienced deterioration in bladder dysfunction level before untethering, and all returned to a milder level afterward. A total of 10 patients had unchanged bladder dysfunction before symptoms and preoperatively. Of these patients 9 (90%) continued unchanged after untethering, while 1 deteriorated. CONCLUSIONS After untethering secondary to myelomeningocele 35% of the patients experienced improved bladder function and 5% deteriorated. All of the patients who deteriorated before untethering improved afterward, and 90% of those who were stable preoperatively continued to be stable postoperatively. Therefore, regular evaluation of bladder function in children with myelomeningocele should be performed.

Abstract
OBJECTIVE To evaluate the frequency of difficulties when using ultrasonography (US, commonly used to visualize the upper urinary tract) to evaluate renal length and dilatation in children and adolescents with meningomyelocele (MMC), who have excessive obesity or a distorted spine. PATIENTS AND METHODS The records of all children with MMC investigated during 1996-2002 were assessed retrospectively and the last investigation used for analysis. In addition to the US results, the body mass index (BMI) and angulation of the spine were recorded. RESULTS Of the 160 children investigated, US was not evaluable in 46 (29%), i.e. in 35 (22%) for renal length, in one (1%) for dilatation and in 10 (6%) for both. In 99 patients with a straight spine and mild to moderate angulation, renal length was not measurable in 14 (14%), while dilatation was not evaluable in two (2%). In 61 patients with a severely angled spine, the corresponding values were 31 (51%) and nine (15%), respectively. In eight patients with a BMI of >or= 27 kg/m2 and a straight spine, four of the investigations were not completely evaluable, while six were not in the eight patients with both a BMI of >or= 27 kg/m2 and severe angulation. CONCLUSION Both severe spinal angulation and a BMI of >or= 27 kg/m2 significantly reduced the possibility of evaluating the urinary tract by US. However, in an unselected group of children with MMC, dilatation could be evaluated in >90% and renal length in approximately 70%.

Abstract
PURPOSE We determined what is important to feel good in daily life when living with a long-term illness that requires daily treatment routines. MATERIALS AND METHODS Seven boys between 6 and 16 years old who were born with posterior urethral valves narrated their experiences with daily life. They were on clean intermittent catheterization, had impaired renal function and 2 had undergone transplantation. RESULTS Being involved in decisions about themselves was important, as was having their own doctor and nurse. Friends were important. Clean intermittent catheterization was something that worried them in relation to friends and made them feel uncertain about how they would react to it. The boys accepted the catheterization procedure as something that had to be done but they needed strategies to be able to comply. A single event, such as no available toilet, was enough to interrupt treatment. CONCLUSIONS In these boys prescribed treatment was a surprisingly small part of their lives. The clean intermittent catheterization routine was sometimes experienced as an obstacle in company with friends. The new challenge might be to achieve compliance with the treatment routine in daily life in a long-term perspective.

Hypospadias repair with tubularized incised plate. Is uroflowmetry necessary postoperatively? J Pediatr Urol 2006; 2:304-7.

Abstract
OBJECTIVE Hypospadias repair with tubularized incised plate urethroplasty (TIP) produces good cosmesis, but is reported to result in a change in urinary stream postoperatively, with an obstructive pattern. The aim of this retrospective study was to determine whether early uroflowmetry is a good method for diagnosing neourethral stricture. PATIENTS AND METHOD In 126 boys, primary TIP repair was performed between 1999 and 2003. Uroflowmetry was performed in potty-trained boys 2 months' postoperatively (68 boys) and both 2 and 12 months (38 boys) after TIP. Boys with obstructed flow and/or clinical symptoms were calibrated in their neourethra. RESULTS Forty-nine percent of the boys with distal hypospadias and 87% of the proximal cases had a flow rate of less than 10 ml/s at uroflowmetry 2 months after TIP, but only 12/126 boys (10%) were considered to have a neourethral stricture. There was a spontaneous increase in maximum flow rate between 2 and 12 months after TIP repair both in patients who had been calibrated and in boys in whom no intervention had been performed. CONCLUSION Early uroflowmetry appears to be unnecessary, as the voiding history appears to be just as good at alerting a suspicion of urethral stricture after TIP repair. There is a spontaneous normalization of the urinary flow in boys after TIP repair, but the need for long-term follow up beyond puberty is great, especially in cases of proximal hypospadias.

Abstract
PURPOSE We determine by ultrasonography the range of dT in carefully treated and followed children with myelomeningocele, and evaluate the role of such measurements for the understanding of bladder abnormalities in these patients. MATERIALS AND METHODS We studied 66 children and young adults with MMC (34 males and 32 females, median age 8.1 years, range 1.1 to 20.1). Detrusor thickness was measured with a previously established ultrasonographic technique and the results were compared to those in normal children. The variation in detrusor thickness with degree of bladder dysfunction as well as with bladder wall trabeculation, kidney function and anticholinergic treatment was studied. RESULTS The detrusor of the ventral wall was slightly thinner in children with MMC compared to normal. No significant variation in dT was found for different degrees of bladder dysfunction, bladder wall trabeculation, kidney function or anticholinergic treatment. Boys had thicker detrusor of the ventral wall than girls. CONCLUSIONS Children with MMC, followed closely and treated according to international standards, do not acquire detrusor thickening as measured by ultrasonography. The detrusor thickness did not correlate with the degree of bladder dysfunction or renal function, or with anticholinergic treatment. Bladder wall trabeculation at VCU was not associated with bladder wall thickening on ultrasonography. We postulate that in a closely monitored and actively treated population of patients with MMC muscular hypertrophy and the development of connective tissue in the bladder wall is kept to a minimum.

Abstract
PURPOSE The short-term prognosis for boys with posterior urethral valves (PUV) has improved in recent decades, but the long-term prognosis in terms of renal and bladder function and fertility is still a matter of great concern. This study is a followup of boys with PUV and dilated upper urinary tract treated in 1956 to 1970 at the Children's Hospital in Göteborg, Sweden. MATERIALS AND METHODS The records of 54 boys treated for PUV were reviewed. Of 27 boys with PUV and upper urinary tract dilation, 5 boys (18%) died at an early age and 3 boys were lost to followup during adolescence, leaving 19 to be included in the followup. They all answered a questionnaire about renal and bladder function and paternity. RESULTS Of the 19 men 32% were uremic, 21% had moderate renal failure and 47% had not been checked since adolescence. There were signs of bladder dysfunction in 40% and all these subjects had bladder symptoms suggesting detrusor weakness as the cause. All the men were continent. The ability to father children was dependent on whether or not the man was uremic. CONCLUSIONS This long-term followup study emphasizes the importance of checking renal and bladder function throughout life in men born with PUV. Increasing attention to bladder dysfunction and its early treatment could probably improve the long-term prognosis.
