Wijekoon N, Deshpande A. Treatment modalities for paediatric functional daytime lower urinary tract disorders: an updated review. Ther Adv Urol 2024; 16:17562872241241848. [PMID: 38584856 PMCID: PMC10998489 DOI: 10.1177/17562872241241848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Accepted: 02/12/2024] [Indexed: 04/09/2024] Open
Abstract
Paediatric functional bladder disorders especially those causing daytime symptoms are a common cause of significant psychosocial and/or physical morbidity and impaired quality of life. Despite the availability of many therapeutic modalities, a significant number of children appear to be refractory to treatment and continue to have symptoms. In this review, we aim to evaluate the current evidence in the use of existing and novel therapeutic options for the management of daytime lower urinary tract disorders in children. We also aim to highlight the controversies around the terminology and diagnosis of paediatric lower urinary tract dysfunction (LUTD) and specific conditions. The article will then provide a reasonable critique of the existing and emerging treatment modalities in functional daytime LUTD in children including their mode of action, efficacy, indications, and recent advances. These include standard urotherapy, specific urotherapy comprised of biofeedback, alarm therapy and electrical neural stimulation and pharmacotherapy involving selective and non-selective anticholinergics, ß3 adrenergic agonists, alpha blockers and botulinum toxin. A better understanding of this common clinical problem may help clinicians achieve better profiling of these children's diagnoses to further enable specific, targeted treatment.

Abstract
OBJECTIVE To describe and evaluate efficacy of a more practical, at-home regimen of parasacral transcutaneous electrical nerve stimulation (TENS) for pediatric overactive bladder (OAB). METHODS We prospectively enrolled patients with OAB. INCLUSION CRITERIA age 5-13 years and willingness to try TENS. EXCLUSION CRITERIA urinary tract anatomic abnormalities, current use of OAB medications, neurologic condition, and elevated post-void residual. Patients were instructed to complete 20-minute sessions 2x/day for one month. RESULTS We enrolled 21 patients (3 male, 18 female; median age 9.9 years). We had complete VSS data on 17 patients and frequency-volume chart data on 12 patients. Median % of TENS sessions completed was 98%. CONCLUSION In our cohort of medically-refractory OAB pediatric patients, nearly half reported subjective improvement with our regimen, despite modest objective improvement. Our compliance rates suggest this regimen is practical but may be best used as an adjunct to other therapies.

Abstract
Overactive bladder (OAB) is clinically defined as the presence of urinary urgency and may be associated with diurnal urinary incontinence, frequency, and enuresis, and/or constipation. In children aged 5–10 years, the prevalence is 5–12%. Association with emotional disorders is widely described in the literature. Constipation is associated with voiding symptoms because of crosstalk between the gastrointestinal tract and the urinary tract. OAB is believed to be multifactorial. Correct functioning between the pontine micturition centre, the periaqueductal grey matter, anterior cingulate gyrus, and prefrontal cortex is important for correct voiding development and the process of maturation. Patients with OAB have greater anterior cingulate gyrus activity and deactivation of the pontine micturition centre urinary inhibition process, leading to a greater frequency of bladder repletion sensation. Urotherapy is the first treatment to be initiated and aims to change behavioural patterns inthese patients. Other treatment options are anticholinergics, with oxybutynin being the most widely studied, but also described is the use of tolterodine, darifenacin, and mirabegron. Alternative treatments, such as nerve stimulation in the parasacral or the posterior tibial area, have shown improvement of symptoms in comparative studies with conventional drug treatment, and, in refractory cases, botulinum toxin A is an option. In this article, we review the pathophysiology, associated conditions, and aspects related to diagnosis and treatment of OAB.

Abstract
Purpose To identify which independent variable would be strong predictor of febrile urinary tract infection (UTI) in children and adolescents with overactive bladder. Materials and Methods A search was made of the institute's database for all patients diagnosed with overactive bladder over the preceding four years. Children and adolescents under 18 years of age with overactive bladder and no neurological or anatomical alterations of the lower urinary tract were included in the study. The independent variables were: sex, age, ethnicity (Brazilians of African descendence/others), the presence of urinary urgency, daytime incontinence, enuresis, frequent urination, infrequent voiding (≤3 voids/day), nocturia, holding maneuvers, straining to void, intermittent urinary flow, constipation and encopresis. An analysis was conducted to identify patients with febrile UTI and subsequently determine predictors of this condition. Univariate and multivariate analyses were performed. Results Overall, 326 patients (214 girls/112 boys) were evaluated. The mean age of the patients was 7.7±3.19 years (± standard deviation). The incidence of febrile UTI was 39.2%. Being female and infrequent voiding were factors significantly associated with febrile UTI, both in the univariate and multivariate analyses. Conclusions These results show that being female and infrequent voiding constituted significant risk factors for a diagnosis of febrile UTI in these children.

Abstract
PURPOSE Lower urinary tract dysfunction in school-aged children is common and yet data are lacking on current teacher practice regarding bathroom use and daytime incontinence during classroom hours. We determined the prevalence of elementary school teachers who promote lower urinary tract health and identified predictors for and against such behavioral promotion. MATERIALS AND METHODS We performed an electronic cross-sectional survey among self-identified teachers using targeted social media advertisement during a 1-week period in July 2014. The empirical survey tool consisted of 27 questions and collected data on 5 principal domains, including 1) teacher demographics, 2) rules and regulations on water intake and bathroom use during classroom hours, 3) characteristics of school bathrooms in terms of safety, supervision and suitability for use, 4) experience with and management of students with daytime incontinence and 5) training on the topic of lower urinary tract health. Predictors for promoting lower urinary tract health were identified by multivariable logistic regression. RESULTS Of the 4,166 teachers who completed the survey 88% indicated that they encourage students to hold urine. Despite strict bathroom protocols 81% of teachers allowed children unlimited access to water. Of the teachers 82% reported never having undergone any professional development on bathroom regulations for children. Overall only 24% of surveyed teachers met criteria for promoting lower urinary tract health. The odds of promoting lower urinary tract health decreased with ascending grade level (OR 0.80, 95% CI 0.76-0.84). Conversely it increased if teaching experience was greater than 5 years (OR 1.66, 95% CI 1.39-1.98) or professional development on the subject had been received (OR 1.42, 95% CI 1.18-1.70). CONCLUSIONS Of elementary school teachers 76% are not promoting lower urinary tract health in school-aged children. Professional development training on the topics of lower urinary tract dysfunction and/or lower urinary tract health may be beneficial, particularly for educators who teach higher grades and those with less teaching experience.

Abstract
PURPOSE We determined the effectiveness of 2 methods to treat overactive bladder in children using intragroup and intergroup comparisons in a randomized clinical trial. MATERIALS AND METHODS Nine boys and 19 girls with a mean ± SD age of 6.4 ± 2.18 years were randomly divided into group 1-parasacral transcutaneous electrical stimulation with placebo drug and group 2-oxybutynin with sham scapular electrical therapy. Success was assessed by 1) the rate of complete symptom resolution, 2) a visual analog scale of 0 to 10, 3) the dysfunctional voiding score system, 4) voiding diary records, 5) Rome III criteria and 6) side effect frequency in each group. RESULTS A total of 13 and 15 patients were randomized to groups 1 and 2, respectively. Symptoms completely resolved in 6 patients in group 1 (46%) and 3 in group 2 (20%) (p = 0.204). A statistically significant improvement was found in the 2 groups in the dysfunctional voiding score system and voiding diary records. However, no statistically significant difference was found between the groups in the visual analog scale score, voiding frequency, and maximum and mean voided volume (p = 0.295, 0.098, 0.538 and 0.650, respectively). Constipation improved in 100% of group 1 patients but in only 55% in group 2 (p = 0.031 vs 0.073). Group 1 showed no side effects while dry mouth, hyperthermia and hyperemia developed in 58%, 25% and 50% of group 2 patients (p = 0.002, 0.096 and 0.005, respectively). Treatment was discontinued by 13.3% of patients in group 2. CONCLUSIONS Parasacral transcutaneous electrical stimulation was as effective as oxybutynin to treat overactive bladder in children. However, transcutaneous parasacral electrical stimulation was more effective against constipation and showed no detectable side effects. Oxybutynin was more effective for decreasing voiding frequency.

Outcomes of vesicoureteral reflux in children with non-neurogenic lower urinary tract dysfunction treated with dextranomer/hyaluronic acid copolymer (Deflux). J Pediatr Urol 2014; 10:482-7.

Abstract
OBJECTIVE There has been hesitancy to use dextranomer/hyaluronic acid copolymer (DHXA, Deflux for vesicoureteral reflux (VUR) in the setting of lower urinary tract (LUT) dysfunction because of the limited number of published studies, the possibility of less success, and the manufacturer's recommendations contraindicating its use in patients with active LUT dysfunction. We report on our experience using DXHA in this subset of patients whose VUR persisted despite targeted therapy for their LUT condition. MATERIALS AND METHODS We reviewed patients diagnosed with both a LUT condition and VUR who underwent subureteric DXHA while still undergoing treatment for their LUT dysfunction. Persistence of VUR was confirmed by videourodynamic studies (VUDS)/VCUG (voiding cystourethrogram) and all patients were on targeted treatment (TT) and antibiotic prophylaxis prior to and during DXHA injection. VUR was reassessed post-injection. RESULTS Fifteen patients (22 ureters; 21F,1M) met inclusion criteria (mean age 6.1 years, range 4-12). Following one to three DXHA injections, VUR resolved in 17 ureters (77%) including eight of nine ureters in dysfunctional voiding (DV) patients, five of nine in idiopathic detrusor overactivity disorder (IDOD), and four of four in detrusor underutilization disorder (DUD) patients. CONCLUSIONS DXHA is safe and effective in resolving VUR in children with associated LUT dysfunction, even before their LUT condition has fully resolved. Highest resolution rates were noted in patients with either DV or DUD or who were least symptomatic prior to injection.

Abstract
Vesicoureteral reflux (VUR) is a significant risk factor for clinical pyelonephritis and renal scarring. In 2010, the American Urological Association (AUA) reported that bladder and bowel dysfunction (BBD), which is common in patients with VUR, increases the risk of breakthrough UTI in children receiving antibiotic prophylaxis, reduces the success rate for endoscopic injection therapy, and increases the risk of postoperative UTI, irrespective of the surgical success rate for VUR. Accordingly, physicians are strongly recommended to investigate BBD in their patients with VUR. Symptoms and signs of BBD include urinary frequency and urgency, prolonged voiding intervals, daytime wetting, perineal and penile pain, holding manoeuvres (posturing to prevent wetting), constipation, and encopresis. Primary assessment tools include the Pediatric Symptom Checklist, urinalysis, urine culture, bladder diary, measurement of the postvoid residual urine volume, Dysfunctional Voiding Symptom Score, uroflow with electromyography, and Bristol Stool Form Score. The Rome III criteria can also be used for diagnostic assessment of bowel function. Treatment of BBD should be individualized, directed at symptomatic and objective improvement, and can include behavioural modification, biofeedback, selective use of anticholinergics and α-blockers, and bowel management.

Abstract
OBJECTIVE Polyethylene glycol (PEG) is common first-line therapy for urinary symptoms despite minimal evidence-based support. We performed a randomized, double-blind, placebo-controlled study of PEG for initial treatment of overactive bladder (OAB) symptoms in children. PATIENTS AND METHODS Patients aged >3 years underwent baseline urinary symptom questionnaire (USQ, scored 0-16), bowel symptom questionnaire (scored 0-20) and abdominal X-ray (KUB). Patients were randomized to placebo/PEG regardless of parent's perception of constipation. After 1 month, patients completed follow-up questionnaires and KUB. Improvement was defined as decrease in USQ (ΔUSQ) ≥ 3 points. Secondary analyses compared urinary and bowel symptoms to KUB. RESULTS Of 138 enrolled patients, 71 (51.4%) completed 1 month of therapy. Analyses of those randomized to placebo vs. PEG and non-completers demonstrated similar demographics, baseline symptoms, and KUB. Patients treated with placebo and PEG both had significant improvement in USQ scores (p < 0.0001). Patients treated with placebo and PEG responded similarly to placebo (ΔUSQ 3.7 vs. 3.4, p = 0.773), with improvement in nearly half (48.5% PEG vs. 44.7% placebo). There was no correlation between KUB and urinary or bowel symptoms. CONCLUSIONS Nearly 50% of patients with urinary urge symptoms treated with either placebo or PEG for 1 month had improvement in urinary symptoms. KUB did not correlate with baseline or follow-up urinary or bowel symptoms.

Abstract
BACKGROUND The prevalence of vesicoureteral reflux (VUR) is higher in enuretic children than in non-enuretic children. Recent studies have reported VUR in 6-23% of children with enuresis. OBJECTIVES To clarify the association of nocturnal enuresis with vesicoureteral reflux (VUR) and to identify children who are at risk for VUR. PATIENTS AND METHODS During 2007-2009, neurologically normal children who were referred with a chief complaint of nocturnal enuresis and had abnormal renal ultrasonography (US) results, daytime incontinence, abnormal results in urodynamic studies, urinary tract infection, or a history of VUR in their siblings were prospectively evaluated for VUR by voiding cystourethrography (VCUG). RESULTS A total of 60 children (26 boys and 34 girls) aged 5-17 (mean ± SD: 8.46 ± 2.45) years met the inclusion criteria and were enrolled in the study. Twenty-eight (46.7%) patients had mono-symptomatic nocturnal enuresis (MNE), and 32 (53.3%) had non-mono symptomatic nocturnal enuresis (NMNE). VUR was reported in 10 (16.7%) patients and posterior urethral valve (PUV) was found in 1 (1.7%) patient. The prevalence of VUR was significantly higher in patients with daytime incontinence and in girls (P = 0.016 and 0.003 respectively). We did not find any significant correlations between VUR and the form of enuresis (primary versus secondary), urinary tract infection, or any diurnal urinary symptoms other than daytime incontinence (P > 0.05 for all). of 10 renal scintigrams, 5 (50%) showed renal cortical defects. CONCLUSIONS VUR is uncommon in children with MNE and in those with NMNE who do not wet themselves during the day; however, it is a relatively common finding in enuretic children who have daytime incontinence. We recommend VCUG in all enuretic children who have daytime incontinence.

Abstract
PURPOSE There is a known association between nonneurogenic lower urinary tract conditions and vesicoureteral reflux. Whether reflux is secondary to the lower urinary tract condition or coincidental is controversial. We determined the rate of reflux resolution in patients with lower urinary tract dysfunction using targeted treatment for the underlying condition. MATERIALS AND METHODS Patients diagnosed and treated for a lower urinary tract condition who had concomitant vesicoureteral reflux at or near the time of diagnosis were included. Patients underwent targeted treatment and antibiotic prophylaxis, and reflux was monitored with voiding cystourethrography or videourodynamics. RESULTS Vesicoureteral reflux was identified in 58 ureters in 36 females and 5 males with a mean age of 6.2 years. After a mean of 3.1 years of treatment reflux resolved with targeted treatment in 26 of 58 ureters (45%). All of these patients had a history of urinary tract infections before starting targeted treatment. Resolution rates of vesicoureteral reflux were similar for all reflux grades. Resolution or significant improvement of reflux was greater in the ureters of patients with dysfunctional voiding (70%) compared to those with idiopathic detrusor overactivity disorder (38%) or detrusor underutilization (40%). CONCLUSIONS Vesicoureteral reflux associated with lower urinary tract conditions resolved with targeted treatment and antibiotic prophylaxis in 45% of ureters. Unlike the resolution rates reported in patients with reflux without a coexisting lower urinary tract condition, we found that there were no differences in resolution rates among grades I to V reflux in patients with lower urinary tract conditions. Patients with dysfunctional voiding had the most improvement and greatest resolution of reflux. Additionally grade V reflux resolved in some patients.

Abstract
PURPOSE There is a known association between sickle cell disease and enuresis. However, the cause of this association is unclear. We tested the hypothesis that children with sickle cell disease would have more symptoms of overactive bladder than a control group. MATERIALS AND METHODS Questionnaires were distributed to 155 legal guardians of children and adolescents 5 to 17 years old with sickle cell disease and to 100 legal guardians of a control group of children. RESULTS Individuals with and without sickle cell disease were distributed uniformly regarding gender and age. A total of 50 patients (32.3%) in the sickle cell disease group had enuresis vs 5 (5%) in the control group (p = 0.000). Daytime urinary incontinence was observed in 36 individuals with (23.2%) and 11 (11.0%) without sickle cell disease (p = 0.014). A total of 52 patients with sickle cell disease (33.5%) complained of urgency, compared to 10 controls (10%, p = 0.000). A total of 49 patients with sickle cell disease (31.6%) had frequency, compared to 6 controls (6%, p = 0.000). Of all patients who reported enuresis or daytime incontinence only 1 with enuresis had received specific treatment. CONCLUSIONS There is a significant association between sickle cell disease and enuresis and overactive bladder symptoms such as daytime incontinence, urgency and frequency. Thus, all children and adolescents with sickle cell disease should be questioned regarding the presence of these symptoms to facilitate treatment for these conditions.

Abstract
Non-neurogenic elimination disorders cover a wide spectrum of lower urinary tract and bowel dysfunctions, observed in the absence of a neurological background or lower urinary tract malformation. We reviewed conditions responsible for incontinence during bladder filling with normal voiding patterns (such as overactive bladder, giggle incontinence, post-void dribbling), and dysfunctional voiding syndromes. Dysfunctional elimination syndrome usually includes detrusor-sphincter dyscoordination, small-capacity overactive bladder or decompensated large poorly contractile bladder, and large-volume post-micturition residuals, occasionally associated with bowel dysfunction. At the most severe end of the spectrum lies the non-neurogenic neurogenic bladder syndrome, characterized by the association of a severe impairment of the upper urinary tract with a dysfunctional elimination syndrome. It must be emphasized that if the term 'non-neurogenic' relates to the absence of a neurological lesion, it is however conceivable that these conditions actually do have an underlying neurological cause that remains to be identified.

Abstract
PURPOSE We evaluated the long-term success of transcutaneous parasacral electrical stimulation for overactive bladder in children. MATERIALS AND METHODS We prospectively evaluated children who underwent transcutaneous parasacral electrical stimulation for overactive bladder. All patients had symptoms of overactive bladder, bell curve in uroflowmetry and low post-void residual urine. The procedure was performed using a frequency of 10 Hz for 20-minute sessions 3 times weekly for a maximum of 20 sessions. Initial and long-term (more than 6 months) success rates were evaluated. RESULTS Transcutaneous parasacral electrical stimulation was performed in 36 girls and 13 boys with a mean age of 10.2 years (range 5 to 17). Mean followup was 35.3 months (range 6 to 80). Before treatment urgency, daytime incontinence and urinary tract infection were seen in 100%, 88% and 71% of cases, respectively. Initial success (full response) was demonstrated in 79% of patients for urgency, 76% for incontinence and 77% for all symptoms. Continued success was seen in 84% of patients for urgency, 74% for daytime incontinence and 78% for all symptoms. If the 30 patients with at least 2 years of followup were considered, treatment was successful in 73%. Recurrence of symptoms after a full response was seen in 10% of cases. Two of 33 patients (6%) with urinary tract infection before the procedure still had infection after treatment. CONCLUSIONS Transcutaneous parasacral electrical stimulation is well tolerated, and demonstrates short and long-term effectiveness in treating overactive bladder in children. Symptoms eventually will recur in 10% of patients.

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.

Abstract
In this overview the influence of functional bladder disturbances and of its treatment on the resolution of vesicoureteral reflux (VUR) in children is discussed. Historically both bladder dysfunction entities, the overactive bladder (OAB) and the dysfunctional voiding (DV), have been described in conjunction with VUR. Treatment of the dysfunction was also considered to influence spontaneous resolution in a positive way. During the last decades, however, papers have been published which could not support these results. Regarding the OAB, a prospective study with treatment of the bladder overactivity with anticholinergics, did not influence spontaneous resolution rate in children with a dysfunction including also the voiding phase, DV and DES (dysfunctional elimination syndrome), most studies indicate a negative influence on the resolution rate of VUR in children, both before and after the age for bladder control, both with and without treatment. However, a couple of uncontrolled studies indicate that there is a high short-term resolution rate after treatment with flow biofeedback. It should be emphasized that the voiding phase dysfunctions (DV and DES) are more severe than the genuine filling phase dysfunction (OAB), with an increased frequency of UTI and renal damage in the former groups. To be able to answer the question if treatment of bladder dysfunction influence the resolution rate of VUR in children, randomized controlled studies must be performed.

Abstract
AIM To assess the role of the dysfunctional voiding and incontinence scoring system (DVAISS) in children with voiding dysfunction. METHODS Ninety-three children were divided into three groups: those who had wetting only (group 1), recurrent urinary tract infections (UTIs) and wetting (group 2) and vesicoureteral reflux together with wetting and UTIs (group 3). Individualized multiple treatments modalities were applied. The success criteria defined by the reduction in the rate of wetting described as complete response (more than 90%), partial response (50-90%), no response (less than 50%).Also, in group 3, improvement was determined as a decrease of at least two grades in reflux. Scores of patients were determined before and after treatment. RESULTS Complete response rates for groups 1, 2 and 3 were 67.5, 88.8 and 85.71%, respectively. The specificity of the DVAISS in predicting the complete response was 79, 88 and 100%, respectively, and its sensitivity was 100% in all groups. In group 3, improvement rate was 71.4%. The specificity and sensitivity of the DVAISS in predicting the improvement were 83 and 100%, respectively. CONCLUSION The sensitivity of the DVAISS is higher in predicting the treatment effect; however, its specificity is decreased. The DVAISS may be an auxiliary diagnostic tool in voiding dysfunction patients.

Abstract
OBJECTIVE To evaluate the basic knowledge of pre-school teachers who deal with children between the ages of 4 and 7 years, who present signs of lower urinary tract dysfunction (LUTD). MATERIALS AND METHODS We performed a survey with 50 teachers from 9 private schools working with pre-school children. The criteria for selection were if teachers were certified or non-certified elementary school teachers - NCEST and the amount of professional experience. RESULTS Thirty-three teachers considered that the normal daily urinary frequency should be from 4 to 7 times. Two of the 50 teachers considered it normal to urinate less than 4 times per day and 15 teachers considered more than 7 times per day as normal. There was no difference between the 2 categories of certified or NCEST nor between those with more or less than five years of professional experience. Thirty-three percent believed that to urinate more than 4 times during a class period (4-5 hours) could indicate a urinary problem. There was a statistically significant difference among the certified and NCEST but not in terms of time of professional experience. If during this period the child would not ask to urinate, only 18% considered that as an indication of urinary problem. When asked about the symptoms that would indicate urinary urgency and urge incontinence, only 24% of the teachers connected it with urinary problem. There was no difference in terms of professional background or professional experience in these 2 last analyses. CONCLUSION Our data shows evidences that private pre-schools teachers are not well informed of the clinical manifestation of LUTD.

Abstract
PURPOSE Endoscopic injection of stabilized nonanimal hyaluronic acid/dextranomer gel is an established treatment for vesicoureteral reflux in children. We performed a subgroup analysis to assess this treatment in reflux associated with bladder dysfunction. MATERIALS AND METHODS Of 308 consecutive children treated endoscopically with stabilized nonanimal hyaluronic acid/dextranomer gel for dilating vesicoureteral reflux 54 were observed retrospectively to have bladder dysfunction. Initial followup consisted of voiding cystourethrogram at 3 and 12 months after injection, with positive response defined as reflux grade 0 or I. At 7 to 12 years following treatment patient charts were checked for urinary tract infections and bladder dysfunction, and a followup survey (postal questionnaire) was administered. RESULTS A positive response to therapy (cure) was observed in 45 children (83%) after 1 to 3 endoscopic treatments. Concurrently, bladder dysfunction had resolved in 32 patients (59%). After the last stabilized nonanimal hyaluronic acid/dextranomer gel implantation 45 patients (83%) were free of urinary tract infections. Questionnaire results were similar to chart based findings. Stabilized nonanimal hyaluronic acid/dextranomer gel implantation was well tolerated, with no associated complications. CONCLUSIONS Endoscopic treatment with stabilized nonanimal hyaluronic acid/dextranomer gel appears to be similarly effective in patients with vesicoureteral reflux with and without bladder dysfunction. These data indicate that bladder dysfunction should not be considered a contraindication to endoscopic treatment for reflux.

Abstract
OBJECTIVES To evaluate the effectiveness of transabdominal ultrasonography for bladder volume and detrusor muscle thickness and to research the relationship of these measurements with age, height, and body mass index. METHODS We reviewed the records of 244 healthy, school-aged children from February to May 2003. After a complete urologic examination, the weight and height of all children were measured, and their body mass index was determined. Transabdominal ultrasonography with a high-frequency probe was performed to obtain the anterior, posterior, and lateral bladder wall thicknesses. RESULTS The mean age of the children was 10.7 +/- 3.6 years (range 7 to 15), and the mean bladder volume was 256 cm3 (range 78 to 790). The relationship between bladder volume and age was significant (P = 0.0001, r = 0.568). The mean anterior, posterior, and lateral detrusor thickness was 1.42 mm (range 0.8 to 2.8), 1.57 mm (range 0.7 to 3.1), and 1.49 mm (range 0.6 to 2.6), respectively. The relationships between increasing age and the anterior and posterior wall thicknesses were significant (P <0.05), but the relationship between age and the lateral wall thickness was not (P >0.05). The relationship between bladder volume and body mass index was significant (P = 0.0001, r = 0.2959). A strong positive and significant correlation was found between the anterior (P = 0.0001) and posterior (P = 0.001) wall thicknesses and body mass index, but the correlation between the lateral wall thickness and body mass index was not significant (P = 0.079, r = 0.113). CONCLUSIONS Strong, positive correlations were found between the anterior and posterior wall detrusor thicknesses and increased age and body mass index, but the same correlations for lateral wall detrusor thickness were not found.

Abstract
PURPOSE OF REVIEW This review will focus on the diagnosis and management of voiding dysfunction in neurologically and anatomically normal children. The discussion will highlight recent developments and research in the clinical approach as well as the etiology and classification of these disorders. RECENT FINDINGS Voiding dysfunction in children encompasses a wide spectrum of clinical entities, recently classified collectively as dysfunctional elimination syndromes. Voiding dysfunction typically presents after toilet training and may originate from behavioral issues that arise around this time in childhood development. The spectrum of disorders includes urge syndrome, dysfunctional voiding with an uncoordination between the detrusor and urinary sphincter, and enuresis. Clinical symptoms may vary from mild incontinence to severe disorders with endpoints of irreversible bladder dysfunction with vesicoureteral reflux, urinary tract infection and resulting nephropathy. Diagnosis relies heavily on a good history and physical examination, but also includes radiologic and urodynamic evaluation. Treatment generally consists of medical therapy, primarily with anticholinergics as well as behavioral therapy to modify learned voiding patterns that contribute to the voiding dysfunction. SUMMARY This overview of voiding dysfunction in children outlines the established approaches to its diagnosis and treatment and highlights the most recent developments in the field.

Abstract
OBJECTIVES To assess the clinical presentation of children with lower urinary tract dysfunction (LUTD) relating to objective examination data. MATERIALS AND METHODS Forty-four children (36 girls and 8 boys with mean age of 6.8 years) with LUTD were prospectively assessed through a specific questionnaire that analyzed clinical presentation of those patients. These data were then compared to objective data, such as micturition diary and uroflowmetry with electromyography. RESULTS A urinary tract infection (UTI) antecedent was observed in 31 cases (70.5%), and of those, 24 cases of UTI were accompanied by fever. All children presented micturition urgency. Daily urinary incontinence was observed in 33 cases (75%) and nocturnal enuresis in 23 (52.3%). As for micturition frequency, 15 (34.1%) had normal frequency 19 (43.2%) presented more than 10 daily micturition episodes and 10 (22.7%) thought they urinated less than 5 times a day. In the uroflowmetry and electromyography examination, 14 (31.8%) experienced lack of coordination during micturition. Of 10 children with infrequent micturition, 5 confirmed this in their micturition diaries and 2 listed more than 5 micturition episodes per day in the diary. Of 19 patients presenting polaciuria, only 5 confirmed this in their micturition diaries, while 7 had less than 10 micturition episodes per day. CONCLUSION Most children with LUTD presented a previous UTI, and daily incontinence was verified in around 75% of the patients. Complaints of polaciuria or infrequent micturition are not noted completely in the micturition diaries and there is no parameter in the clinical history that offers good sensitivity or specificity for the diagnosis of lack of perineal coordination.

Abstract
Urinary tract infection in babies often presents with non specific symptoms and signs. It must be considered in the differential diagnosis of a febrile sick baby or any baby with failure to thrive. In a significant proportion of babies with recurrent urinary tract infection, urological abnormality is demonstrable. The diagnosis of urinary tract infection is confirmed by the presence of pus cells and growth of microorganism in a fresh urine specimen. The voidoing history and detailed ultrasound examination in the baby including a post void evaluation of the upper and lower urinary tract can lead to the possible diagnosis in the majority. Antibiotic therapy for urinary tract infection should be followed by consideration about the need for urinary drainage at the appropriate level, particularly in cases where resolution is delayed despite antibiotics. There is a role for prophylactic antibiotics after the resolution of acute infection, at least until detailed evaluation several weeks after the acute episode, has excluded any abnormality. Micturating cytourethrogram is usually done under antibiotic cover and better done in centres with facility for fluoroscopic examination. Isotope studies have to be evaluated in the light of inherent limitations. Transient urodynamic abnormality of the urinary bladder in infancy is being increasingly recognized and should be the subject of evaluation in specific circumstances. A multidisciplinary team improves the quality of investigations, subsequent interpretation and long term care of these children. A large majority of urological abnormality in infancy and early childhood can be effectively managed by endocopic procedures. Temporary urinary diversion may be required in a small proportion. Urological reconstruction should be approached with caution, after a detailed analysis of the evolving urological tract in a baby. An aggressive approach to early diagnosis and appropriate treatment of urinary tract infection and any underlying abnormality, has been shown to significantly reduce the incidence of chronic renal failure in long term longitudinal studies in children.

Abstract
Incontinence affects 20%-30% of children. Historically, evaluation of voiding problems in children has involved complete urodynamic studies and treatment based primarily on bladder findings and anticholinergic medications. Unfortunately, success with this approach has been poor. This article describes new advances in our understanding of the causes of nonneurologic pediatric incontinence and its associated problems and provides new treatment strategies to manage these patients. A strategy incorporating an escalating approach to evaluation and treatment is the cornerstone of this approach. Minimizing the routine use of invasive studies and medication is the result.

Abstract
PURPOSE Infants with urinary tract infections (UTI) and no abnormality on radiological evaluation are usually discharged from urological followup but the natural history of these children is unknown. We evaluate the rate of and potential risk factors for UTI recurrence in this specific population. MATERIALS AND METHODS We reviewed retrospectively charts of children evaluated for first UTI before age 6 months between January 1996 and February 2001. Only patients with a normal ultrasound and voiding cystourethrogram were included in this study. A telephone questionnaire was administered to the parents, which inquired about the UTI, duration of breast-feeding, type of formula, family history of UTI, neurological problems, history of constipation or recurrent fevers, as well as social status. Chi-square test was performed for statistical analysis. RESULTS We identified 264 children with UTIs, of whom 119 (45%) had a negative ultrasound and voiding cystourethrogram. Followup was available on 68 girls (81%) and 16 boys (19%) of the 119 children (71%). Of the 84 children 16 (19%) had recurrent UTI. Mean followup was 4.4 years (range 1.9 to 7.0). No factors had a statistically significant correlation for UTI recurrence. The p value for gender and history of undiagnosed fevers was 0.077 and 0.082, respectively. CONCLUSIONS About 20% of children will have recurrent UTIs despite negative radiological evaluation. Although not statistically significant, there was a trend for an increased risk in girls and those with recurrent febrile illnesses. History of daytime dryness and/or constipation was not predictive of recurrent UTIs in our series.

Abstract
OBJECTIVE To evaluate the efficacy and tolerability of tolterodine in children with an overactive bladder, treated in a single incontinence centre. MATERIALS AND METHODS A retrospective analysis of a database of a total of two hundred and fifty-six patients (175 boys and 81 girls, age range 3 years to 17 years, mean age 8.33 years) with urodynamically confirmed bladder overactivity was performed. All children received tolterodine tartrate (dose range of 0.5-4 mg orally). In group I (n=205) tolterodine tartrate replaced anticholinergic drugs (AC) (oxybutinin chloride or oxyphencyclimin hydrochloride). A subgroup of patients switched because of intolerance due to serious adverse events (60.4%) or because of lack of improvement in micturition variables (39.6%). In group II tolterodine was prescribed as initial therapy (n=51). Tolerability was assessed by a standardised questionnaire on adverse events at every outdoor clinic visit. Efficacy assessment was based on micturition diary variables, mean change of maximum bladder capacity and number of incontinence episodes/24 h. RESULTS The mean treatment time was 9.32 months with a range from 1.5 months to 23.4 months. The final dose was 0.1mg/kg orally daily divided into two doses. In group I central nervous system disorders (81%) were the most common adverse events, 26.2% showed flushing, 12.2% accommodation problems and 25.2% had gastrointestinal complaints (constipation, encopresis, abdominal pain). Withdrawal of the non-selective antimuscarinic drug resulted in total recovery from adverse events. Introduction of tolterodine in group I and II caused no serious adverse events. Nine patients (3.5%) reported side-effects and only two discontinued treatment. There were no reports of flushing, troubles of visual accommodation, hyperpyrexia. In group I we observed a mean decrease in urgency by 38.7%, a mean increase in maximal bladder capacity by 33.6% and the number of incontinence episodes decreased by 64.8%. In group II we observed equivalent values with a significant (p<0.001) change in maximal bladder capacity (49.7%), incontinence episodes (64.8%) and micturition episodes/24 h. CONCLUSIONS The results of this retrospective analysis suggest that tolterodine is well tolerated in children and offers an effective treatment for urinary symptoms due to overactive bladder. Tolterodine is superior to non-selective antimuscarinic drugs, with respect to adverse events, allowing more compliance and more effective treatment in children.

Abstract
PURPOSE We investigated bladder function on videourodynamic studies in infants with severe primary vesicoureteral reflux (VUR) and analyzed the relationship between VUR and intravesical detrusor pressure during the micturition cycle. MATERIALS AND METHODS From 1999 to 2001, 3 female and 9 male infants with a median age of 9 months with VUR underwent conventional filling videourodynamics at our institution. Four cases were diagnosed by prenatal detection and 8 were diagnosed after symptomatic urinary tract infections. Reflux was bilateral in 5 cases and unilateral in 7 (grades III to V in 7, 7 and 3, respectively). Controls included 10 age matched infants (median age 4 months) studied with the same urodynamic methodology. RESULTS Median cystometric bladder capacity expected for age +/- SD was 50% +/- 58% (range 20% to 240%). Bladder capacity was low (less than 80%) in 10 patients. Detrusor overactivity during filling was found in only 1 patient. In all except 1 case voiding alternated with peaks of high detrusor pressure (median 87 +/- 25 cm water), associated with intermittent external sphincter contractions with normal coordinated micturition (median 36 +/- 7 cm water). Cystometric residual urine (30% or greater) was noted in 3 cases. In 5 patients VUR occurred with an increase in bladder pressure, while in 7 it occurred during stable filling. No significant cystometric differences were found between patients with reflux and controls. CONCLUSIONS Most infants with VUR had decreased cystometric bladder capacity and normal detrusor activity during filling. High voiding pressure with concomitant sphincteric overactivity coexisted with normal micturition. This voiding pattern might represent a developmental stage of normal urine control and it may have a role in the etiology of reflux in some infants.

Abstract
OBJECTIVE To prospectively assess the prevalence of vesicourethral dysfunction in children over 3 years old, comparing it with the occurrence rate for other potential factors that cause urinary infection in this age range. MATERIALS AND METHODS 36 girls and 9 boys were assessed, with mean age of 6.4 years, ranging from 3 to 13.9 years. These children were prospectively assessed regarding the presence of symptoms of lower urinary tract dysfunction. These data were compared with the retrospective assessment of other potential risk factors for urinary infection. Ultrasonography was performed in 28 children and voiding cystourethrogram was performed in 26 patients. RESULTS Vesicourethral dysfunction was diagnosed in 39 (87%) of the 45 children with urinary infection. Among these 39 patients, all had voiding urgency, 30 (77%) had urinary incontinence, 12 (31%) pollakiuria and 3 (8%) presented infrequent voiding. Vaginal discharge was evidenced in 8 (22%) girls and phimosis in 2 (22%) boys. Obstipation was diagnosed in 10 (22%) cases. Significant post-voiding residue was detected in 4 (13%) of the 28 cases assessed. Vesicoureteral reflux was evidenced in 5 (19%) of the 26 patients who underwent voiding cystourethrogram. In only 2 (4%) cases there was not an apparent cause for the infection. CONCLUSION Vesicourethral dysfunction is a major cause of urinary infection in children with ages above 3 years old. In cases where voiding dysfunction in not present, other predisposing factors must be assessed. However, only 4% of the patients did not present an apparent urologic cause for the infection.

Abstract
OBJECTIVES To clarify the characteristics of vesicoureteral reflux detected in patients with nocturnal enuresis. METHODS Voiding cystourethrography (VCUG) was applied in 1,088 patients who visited our outpatient clinic with the chief complaint of nocturnal enuresis. The clinical features of reflux were evaluated and the prognosis of reflux and nocturnal enuresis was analyzed. RESULTS Reflux was detected in 86 ureters in 70 patients (6.4%) out of the 1,088 patients. The grade of reflux was 3 or less in all cases. The incidence of pyuria was 5 (7%) and that of renal scar during first examination was 1 (1%). The incidence of unstable bladder was 30 (75%) in 40 patients. The resolution rate of reflux in the cases which were followed-up for 2 years or more by conservative treatment was 50-66% for each grade of reflux. The percentage of patients who had siblings with a positive history of nocturnal enuresis and the incidence of frequency differed significantly between the enuretics with reflux and the 507 enuretics without urological abnormalities. CONCLUSIONS Our data suggest that the incidence of reflux in patients with nocturnal enuresis was rather low in comparison with the past literature, the severity was mild and the resolution rate by conservative treatment was rather high.

Abstract
The overactive bladder (OAB) in children is defined as both involuntary detrusor contractions and urethral instability. The development of urinary control plays a key role in its incidence and in our understanding of its pathogenesis. It is seen in a number of conditions but by far is most common among patients with dysfunctional voiding. Urinary infection can be both a cause and an effect of OAB. In some instances, vesicoureteral reflux may result from detrusor overactivity because its successful resolution has been shown to depend on abolition of the hyperactivity. Early diagnosis and appropriate treatment can affect upper urinary tract function and drainage and ultimate bladder function. Recognition is noted via a thorough history and careful physical examination. Urodynamic assessment is indicated in neurologically normal children >5 years old and is combined with a voiding cystourethrogram in boys and a radionuclide cystogram in girls who have a history of recurrent urinary infection. Treatment consists of prophylactic use of anticholinergic agents in patients with neurologic dysfunction, as an early adjunctive measure in boys after ablation of posterior urethral valves, and in children with vesicoureteral reflux. The dose must be carefully titrated in children with cerebral palsy to prevent the appearance of elevated residual urine. Behavioral therapy and biofeedback techniques are effective alternatives to anticholinergic agents for children with dysfunctional voiding.

Abstract
PURPOSE We created a computer model for evaluating the effect of dysfunctional voiding on the costs of managing vesicoureteral reflux in children. MATERIALS AND METHODS The literature on vesicoureteral reflux was reviewed to create a set of assumptions regarding the epidemiology, likelihood of resolution, need for operative intervention, risk of infection and appropriate regimen for nonoperative surveillance. Recent literature describing the effect of dysfunctional voiding on the clinical course of vesicoureteral reflux was included in the model to compare the costs of treating vesicoureteral reflux in children with and without dysfunctional voiding. A 5-year management period was considered. RESULTS Dysfunctional voiding in children with vesicoureteral reflux increased the cost of treatment per patient by 51.2%. The cost per patient increased with increasing grade in those with and without dysfunctional voiding. The difference in costs in the 2 groups increased from 18.7% for grade 1 reflux to 62.1% for grade 5. Sensitivity analysis was performed, in which the risk of urinary tract infection, rate of surgical resolution, incidence of dysfunctional voiding and discount rate varied. The cost in children with dysfunctional voiding remained higher in all scenarios studied, showing the robustness of the model. CONCLUSIONS Dysfunctional voiding substantially increases the costs of treating children with vesicoureteral reflux due to the higher rate of urinary tract infection in children with dysfunctional voiding. Methods that would decrease the rate of urinary tract infection in children with dysfunctional voiding and vesicoureteral reflux would lead to a significant saving of health care dollars.

Abstract
PURPOSE To our knowledge the prevalence and cause of giggle incontinence in children is not known. We hypothesized that laughter may induce unstable detrusor contractions in children susceptible to detrusor instability. We evaluated the prevalence of diurnal voiding symptoms of urinary urgency, urge incontinence, pelvic withholding maneuvers and hesitancy in patients with giggle incontinence, the prevalence of giggle incontinence in patients with diurnal voiding symptoms, the prevalence of the 2 conditions in first degree relatives of patients with giggle incontinence, the influence of treatment for detrusor instability on the frequency of giggle incontinence and the prevalence of diurnal voiding symptoms in control children with giggle incontinence. MATERIALS AND METHODS Of 1,421 children 5 to 15 years old referred to the pediatric nephrology department for various problems 109 were diagnosed with giggle incontinence and 460 had diurnal voiding symptoms. A total of 627 children visiting the pediatrician office whose parents completed a survey questionnaire served as controls. RESULTS Diurnal voiding symptoms were noted in 95% of the patients with giggle incontinence, while giggle incontinence was noted in 23% of those with diurnal voiding symptoms. Of the patients with giggle incontinence a positive family history for that entity and diurnal voiding symptoms was noted in 13% and 28%, respectively. Giggle incontinence improved in all patients after treatment for detrusor instability and it resolved completely in 89%. Giggle incontinence recurred with a relapse of diurnal voiding symptoms in 28 cases and improved with improved diurnal voiding symptoms during modification of therapy. Diurnal voiding symptoms were present in 43% of the 157 controls with giggle incontinence. CONCLUSIONS Giggle incontinence results from detrusor instability induced by laughter and it improves with effective treatment of detrusor instability.

Abstract
OBJECTIVE To describe the tolerability and efficacy of clean intermittent catheterization (CIC) in the management of dysfunctional voiding in patients who are neurologically and anatomically normal. PATIENTS AND METHODS The medical records were reviewed in 23 patients (16 girls, mean age 9 years, range 6-14.5, and seven males, mean age 8 years, range 5-20.5) with urinary incontinence and/or urinary tract infection (UTI) who were offered CIC because they had a large postvoid residual urine volume (PVR). All had extensive instruction before starting CIC. All patients underwent urodynamic studies, and urinary and fecal elimination habits were recorded. Detrusor hyperactivity, when present, was treated with anticholinergic medication. The follow-up evaluation included tolerance of CIC, continence status and the incidence of UTI. Behavioural modification or biofeedback training was not used in any patient. RESULTS Of the 23 patients, 13 presented with both UTI and urinary incontinence, five with incontinence only, four with UTI only, one with frequency and no incontinence, and one with haematuria. Associated symptoms included frequency/urgency, constipation or soiling, and straining to void or incomplete emptying (in nine each), and infrequent voiding in six. CIC was performed within 2 days by 15 patients, while four others required up to 2 weeks to master CIC. However, three of the four patients (all older girls) who needed 2 weeks to learn the technique did not tolerate CIC and discontinued it within 3 weeks. Four other adolescents (three girls and one boy) refused to learn CIC. Of the 16 patients remaining on CIC only three had cystitis; no patient had a febrile UTI. Once successfully instituted, all patients became continent while on CIC. Six boys (mean follow-up 4 months) had a marked decrease in their PVR. CIC was discontinued in three girls who voided normally to emptiness within 6 months of starting CIC; they remained dry and infection-free 16 months (two) and 6 years later. CONCLUSION CIC is a viable therapeutic option for the treatment of dysfunctional voiding, associated with a large PVR, in the absence of any neurological abnormality. CIC is well tolerated in the sensate patient and provides a means for expeditiously achieving continence and improving bladder emptying cost-effectively.

Abstract
PURPOSE We determine the ultrasonographic detrusor thickness in healthy infants and children. MATERIALS AND METHODS We studied 150 healthy children, 79 boys and 71 girls, from newborns to 13 years old. The detrusor of the ventral and dorsal wall was measured with a previously established ultrasonographic technique, and the variation with age and bladder fullness was assessed. RESULTS Detrusor thickness varied significantly with the degree of bladder fullness (thinner at higher volumes). It also increased slightly with age. At bladder fullness of 10% or greater of expected bladder capacity (EBC), calculated using the formula EBC (ml.) = age (years) x 30 + 30, a practical upper limit for the detrusor thickness of the ventral wall at all ages was 2.0 mm. at a bladder fullness up to 50% of expected bladder capacity or 1.5 mm. at a higher degree of fullness. The detrusor of the ventral wall was slightly thicker in boys than in girls and also somewhat thicker than the detrusor of the dorsal wall. CONCLUSIONS The results indicate that ultrasonographic measurements of detrusor thickness in children may serve as a diagnostic tool and its usefulness in clinical as well as research work should be explored.

Abstract
Elimination dysfunction is a functional disease that encompasses the urinary and GI tracts. Because the presentation is varied and ED is a disease of exclusion, a thorough history and physical examination are mandatory. Noninvasive management that includes the "fundamental four" and continuous engagement and encouragement of the patient and family are the pillars of treatment. For patients who are refractory to this approach, new research in children-directed biofeedback research shows promise.

Abstract
Data concerning learned voiding dysfunction (Hinman syndrome; non-neurogenic, neurogenic bladder) in adults are scarce. The present study was conducted to assess the pre-valence and clinical characteristics of this dysfunction among adults referred for evaluation of lower urinary tract symptoms. Learned voiding dysfunction was suggested by a characteristic clinical history and intermittent "free" uroflow pattern and by the absence of any detectable neurological abnormality or anatomic urethral obstruction. A definitive diagnosis was made by the demonstration of typical external urethral sphincter contractions during micturition by EMG or fluoroscopy. A urodynamic database of 1,015 consecutive adults was reviewed. Twenty-one (2%) patients (age, 24-76 years) met our strict criteria of learned voiding dysfunction. Obstructive symptoms were the most common presenting symptoms, followed by frequency, nocturia, and urgency. Eight (35%) patients had recurrent urinary tract infections, seven of these being women. None of the patients had any clinically significant upper urinary tract damage. First sensation volume was significantly lower in women than in men. Both detrusor pressure at maximum flow and maximum detrusor pressure during voiding were found to be significantly higher in men than in women. Further differentiation between adult women and men failed to reveal any other clinically significant differences. In conclusion, by strict video-urodynamic criteria, 2% of our patients had learned voiding dysfunction. Other patients, with presumed learned voiding dysfunction, who did not undergo video-urodynamics were not included in the present series. Thus, the prevalence of learned voiding dysfunction among adults referred for evaluation of lower urinary tract symptoms is likely to be even higher.

Abstract
OBJECTIVE To ascertain the aetiology and epidemiology of non-neurogenic bladder sphincter dysfunction (NNBSD) by assessing the results of prospective video-urodynamic studies (VUD) in 1000 children. PATIENTS AND METHODS During a 4-year study period (January 1995 to December 1998) 1000 children prospectively underwent VUD to further define their NNBSD. After a noninvasive screening assessment consisting of a history, voiding diary, clinical examination, urine analysis, ultrasonography and uroflowmetry, those children who would benefit from further VUD were selected. The selection criteria included a history of urinary tract infection (UTI), a small bladder capacity not responding to training, dysfunctional uroflow, ultrasonographic abnormalities and resistance to therapy. During the study period 3500 children were screened for incontinence problems, including monosymptomatic nocturnal enuresis; 1000 of these were selected for VUD (524 boys and 476 girls). RESULTS The urodynamic diagnosis was of normal bladder-sphincter function in 62 (6.2%, male : female 44 : 56), urge syndrome in 582 (58%, 58 : 42), dysfunctional voiding in 316 (32%, 49 : 51) and 'lazy bladder' in 40 (4%, 20 : 80). Boys diagnosed with a 'lazy bladder' were younger than those with urge syndrome and dysfunctional voiding. Girls with dysfunctional voiding were younger than those with urge syndrome. The incidence of UTI was significantly higher in girls than in boys; boys with NNBSD had no greater risk for UTI and in girls the general risk was 34%. Only in girls with a lazy bladder was there a significantly higher incidence of UTI (53%). Reflux occurred equally in all groups, with an overall incidence of 15%. The incidence of obstipation was significantly higher in girls with a lazy bladder, and overall was 17%. CONCLUSION These results from a large series provide a new insight into the epidemiology and pathophysiology of NNBSD. The age distribution provides evidence against a dysfunctional voiding sequence. The risk of developing UTI in NNBSD is greater only in girls. In children with a lazy bladder the risk is also significantly higher, indicating that residual urine is a greater risk factor than detrusor instability. Urge syndrome and dysfunctional voiding in girls carry the same risk for developing UTI, indicating that bladder instability is a higher risk factor for UTI than detrusor sphincter discoordination. All dysfunctions carry an equal risk for developing secondary reflux. Children with NNBSD have different primary diseases but all have a common risk of incontinence, UTIs, reflux and obstipation.

Abstract
Over the last several decades voiding dysfunction in children has primarily been associated with incontinence and thought to be secondary to bladder instability from delayed brain maturation. Full urodynamic evaluation became the standard recommendation and treatment centred on early institution of anticholinergics. Recently, this strategy has been questioned as medical programs including pelvic floor muscle treatments have shown tremendous success in curing incontinence, decreasing surgical rates for vesicoureteral reflux, and decreasing recurrent urinary tract infections.
