Abstract
INTRODUCTION Among the conditions underlying childhood daytime incontinence the most frequent is overactive bladder (OAB). Parasacral transcutaneous electrical nerve stimulation (parasacral TENS) is a promising therapy for OAB treatment in children; however, there is no standard treatment protocol. OBJECTIVE To evaluate the immediate and continued effects of parasacral TENS monotherapy in children with OAB. STUDY DESIGN 57 children at mean age 10.8 years diagnosed with OAB at a single centre were prospectively enrolled from 2013 to 2018. The inclusion criterion was typical OAB symptoms. The treatment results were evaluated based on objective measurements from bladder diaries, 48 h frequency/volume (48 h F/V) charts, and uroflowmetry. The parasacral TENS treatment lasted for 4 months, twice daily, with 1 h sessions. Results were evaluated at three time points: 2 months of therapy, 4 months (end of active therapy), and 10 months (6 months after cessation of therapy). RESULTS After 4 months of parasacral TENS treatment, the number of days with daytime incontinence decreased from 7.23 to 3.94/14 days (p < 0.05), nocturnal enuresis decreased from 6.81 to 3.77/14 days (p < 0.05), and urgency episodes from 7.36 to 3.58 in 14 days (p < 0.05). Treatment effects remained stable 6 months after therapy cessation regarding days with daytime incontinence (from 3.94 [immediately after treatment] to 3.28 in 14 days [6 months after treatment cessation]), nocturnal enuresis (from 3.77 to 2.91 in 14 days), and urgency episodes (from 3.58 to 2.12 in 14 days) (p < 0.05). Complete response after 6 months of therapy was observed in 32% of patients with daytime incontinence, 35% with nocturnal enuresis, and 50% with urgency episodes. DISCUSSION A recent systematic review of parasacral TENS in children with OAB included only two studies with a follow up of 6 months or longer after treatment cessation; therefore, little is known about the continued effects of parasacral TENS. High rates of complete symptom remission were reported in studies where only subjective symptoms were evaluated. Results of our study reveal that the positive effect of treatment persist. The strengths of the present study include its prospective design, large sample size, and uniform standard urotherapy performed prior to TENS. CONCLUSIONS The use of parasacral TENS in children with OAB is effective and results in a significant reduction in daytime incontinence, nocturnal enuresis, and urgency episodes. A longer treatment duration of 4 months leads to more improvement and the effects remain stable 6 months after treatment cessation.

Abstract
BACKGROUND Overactive bladder (OAB) is the most prevalent lower urinary tract dysfunction among children. Refractory OAB lacks response to the first line treatments, including anticholinergic, and it is a major clinical challenge. This study aims to compare the efficacy of para-sacral transcutaneous electric nerve stimulation (PS-TENS) in the treatment of primary and refractory OAB among children. METHODS A prospective, randomized clinical study included 64 children aged 5-12 years with OAB divided equally into two groups: group (1) included 32 children with treatment-naive OAB, while group (2) included 32 children with refractory OAB who failed complete course of anticholinergics. Both groups received PS-TENS three times weekly for 12 weeks. Detailed medical history, voiding diary, ultrasound, and uroflowmetry with EMG were performed at baseline and after 12 weeks of treatment. Filling cystometry was performed for children with refractory OAB before and after PS-TENS. RESULTS After the end of treatment the number of children with urge incontinence decreased significantly among the two groups: from 25 to 13 and 27 to 15 for the primary and refractory groups, respectively. Micturition frequency per 24 h decreased significantly among children with primary OAB. Bladder capacity increased significantly and the resting detrusor pressure decreased significantly among children with refractory OAB. CONCLUSIONS PS-TENS is an effective and safe treatment option for children with OAB. The magnitude of improvement is higher among children with primary as compared to refractory OAB.

Abstract
INTRODUCTION Neurological defects in children with cerebral palsy (CP) not only affect their motor skills but also lead to bladder and bowel problems. Although most children with CP have achieved urinary control, more than 50% of cases experience lower urinary tract symptoms (LUTS). Common LUTS complaints observed in CP include delayed toilet training, urinary incontinence, increased frequency of urination, urgency, urinary hesitancy, and recurrent urinary tract infections. OBJECTIVE This study aimed to prospectively evaluate and compare the effectiveness of two different physiotherapy approaches, sacral Transcutaneous Electrical Nerve Stimulation (TENS) and massage, on lower urinary tract dysfunction in children with CP. METHOD A total of 54 children with CP who had the Dysfunctional Voiding Scoring System (DVISS) of 8.5 or higher were included in the study. Children were randomized to the TENS (TG; n = 27) and Manual Therapy (MG; n = 27) groups. TENS application was performed 2 sessions in a week for 20 min for a total of 12 weeks. The electrodes used during the application were adhered bilaterally to the parasacral region (S2-S4). 4 electrodes of 5 × 5 cm were used. Classical bowel massage was applied to the MG with the friction massage technique twice a week for 12 weeks. Manual therapy applications were performed in the form of abdominal, colon, and friction massage, twice a week for 20 min by the physiotherapist. Massage was applied to the abdominal region between the lower subcostal border and the anterior superior iliac spine. Questionnaires were applied before and after treatment interventions: DVISS, functional bladder capacity (FBC), frequency of voiding, and urinary incontinence episodes evaluated by bladder diary, Bristol Gaita Scale, and Pediatric Incontinence Quality of Life Scale (PIN-Q) used. RESULTS The decrease in the episodes of incontinence was higher in the TG (p = 0.037; p < 0.05). FBC increased after treatment in both groups, but there was no statistically significant difference between the groups (p = 0.683; p > 0.05). Manual therapy was more effective in improving constipation symptoms. In both groups, DVISS and PIN-Q values decreased after treatment, but the decrease in TG was statistically significant in the evaluation made between groups (p = 0.001; p < 0.01). CONCLUSION Both parasacral TENS and massage provided a significant improvement in LUTS, constipation, and quality of life but TENS showed a bigger improvement. We suggest adding these interventions to the treatment of bladder and bowel problems in CP children.

Abstract
Overactive bladder (OAB) is clinically defined as urinary urgency with or without urinary incontinence. It is associated with daytime frequency or constipation and has a prevalence of approximately 5%-12% among 5- to 10-year-olds. The appropriate functional exchange between the pontine micturition center, periaqueductal gray matter, and prefrontal cortex is important for proper micturition control. Several studies on pediatric cases observed a link between OAB and neuropsychiatric problems, such as anxiety, depression, and attention deficit, and treatment of these comorbidities improved patient symptoms. In this review, we present the pathophysiology of OAB, its associated conditions, and aspects related to updates in OAB treatment, and we propose a step-by-step treatment approach following this sequence: behavioral therapy, medical treatment, and invasive treatment. Although anticholinergic drugs are the mainstay of OAB medical treatment, beta-3 agonists and alpha-blockers are now recommended as a result of significant advancements in pharmacologic treatment in the last 10 years. Electrical stimulation techniques and botulinum toxin are also effective and can be used, especially in conventional treatment-refractory cases.

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.

J Pediatr Urol 2021; 17:644.e1-644.e10. [PMID: 34176749 DOI: 10.1016/j.jpurol.2021.06.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Revised: 03/17/2021] [Accepted: 06/07/2021] [Indexed: 12/27/2022]
Abstract
BACKGROUND Nowadays there is still no ideal treatment for paediatric overactive bladder. Initial management measures (urotherapy and constipation control), resolve 40% of cases. The second line of treatment in overactive bladder is anticholinergic drugs, above all oxybutynin. Although most patients improve with these therapies, the complete resolution rate is around 30-40%. Sacral transcutaneous electrical nerve stimulation has recently emerged as a new alternative in the management of patients with refractory paediatric overactive bladder. However, only a few studies have been done to compare the effectiveness of this therapy versus conventional drugs. OBJETIVE The objective of the present study is to compare, in children with overactive bladder, the efficacy of the sacral transcutaneous electrical nerve stimulation versus oxybutynin therapy. MATERIALS AND METHODS We performed a prospective and randomized study of patients with diagnosis of overactive bladder treated with sacral transcutaneous electrical nerve stimulation versus oxybutynin, during the period July 2018-July 2020. Patients refractory to standard urotherapy and constipation management randomly received one of the therapeutic alternatives. Treatment was maintained for 6 months. RESULTS 86 patients were included in the study: 40 patients received electrotherapy (group 1) and 46 patients received oxybutynin (group 2). Before starting the treatment assigned both groups were comparable related to the voiding symptomatology as well as the severity of the overactive bladder. Sacral transcutaneous electrical nerve stimulation was significantly more effective than oxybutynin, with a higher percentage of complete resolution of symptoms in the management of paediatric overactive bladder. VOIDING DIARY All the parameters obtained with the voiding calendar significantly improved in both groups at the end of the treatment. The increase in MaVV was significantly higher in group-1. DVISS (DYSFUNCTIONAL VOIDING AND INCONTINENCE SCORING SYSTEM) We observed a progressive decrease in the mean score obtained in the DVISS questionnaire over time in both groups. This decrease was significantly higher in group-1 compared to group-2 (p < 0.005). The mean value obtained in the DVISS questionnaire in group-1 was 6 (interquartile range: 3-9) at the end of the treatment (lower than the diagnostic cut-off point for daytime condition in the DVISS, 8.5). In group-2, the mean value obtained in the DVISS questionnaire was 10 (interquartile range: 8.75-13.25), higher than the cut-off point. COMPLICATIONS A greater number of adverse effects was obtained in group-2 (26.1% versus 15%, p < 0.05). Constipation (n: 6, 10.9%), and abdominal pain (n: 2,4.3%) were the most frequent adverse effects in this group. The adverse events reported in group-1 were contact dermatitis (n: 1.2%) and fecal losses [2] or urgency [5]. CONCLUSION Oxybutynin and sacral transcutaneous electrical nerve stimulation are both effective therapies in the management of paediatric overactive bladder. However, electrotherapy has been shown to be a more effective therapy with a complete clinical resolution rate in a larger number of patients. Furthermore, the rate of adverse effects secondary to electrotherapy is significantly lower than those treated with oxybutynin.

Abstract
This article aims to explore changes in urinary concentrations of selected neurotrophins in the course of TENS therapy in children with overactive bladder (OAB). A two-group open-label prospective study was conducted. The intervention group comprised 30 children aged between 5 and 12 years old with OAB refractory to conservative therapy. They received 12 weeks of TENS therapy in a home setting. The urinary neurotrophins, NGF, BDNF, NT3, NT4, were measured by ELISA at baseline and at the end of the TENS therapy. Total urinary neurotrophins levels were standardized to mg of creatinine (Cr). We compared the results with the reference group of 30 participants with no symptoms of bladder overactivity. The results revealed that children with OAB both before and after TENS therapy had higher NGF, BDNF, and NT4 concentrations in total and after normalization to Cr than the reference group in contrast to NT3. The response to the therapy expressed as a decrease of urinary neurotrophins after TENS depended on the age and the presenting symptoms. In conclusion, children older than 8 years of age with complaints of daytime incontinence responded better to TENS.

Abstract
Purpose: This study compares the results achieved following parasacral TENS administered using two different weekly schedules. Materials and Methods: Children of at least four years of age with a diagnosis of pure overactive bladder were included in this randomized clinical trial and treated with parasacral TENS (2 versus 3 sessions per week). All the participants also underwent standard urotherapy. Results: Sixteen children were included in the twice-weekly group and eighteen in the three times weekly group. There were no statistically significant differences between the two groups with respect to sex; however, there was a difference in age. There were no significant differences regarding complete resolution of urinary symptoms, with 8 children (50%) in the twice-weekly group and 11 children (61%) in the three times weekly group having their symptoms completely resolved (p=0.73). There was a significant difference in the DVSS score in both groups following TENS treatment compared to baseline (p=0.0001 for both groups), but not between groups. Evaluation of the bladder diary showed no difference between the groups before or after treatment. Conclusion: For children with overactive bladder who are unable to undergo parasacral TENS treatment three times weekly, the method can be administered successfully at twice-weekly sessions.

Abstract
AIMS Despite published evidence in recent decades suggesting improvement in lower urinary tract symptoms (LUTS) with the use of parasacral transcutaneous electrical nerve stimulation (PTENS), no consensus guidelines for therapy exist. This study systematically reviews the literature to assess the effect of PTENS in children with LUTS. METHODS A database search conducted up to December 2019 included Medline, EMBASE, and the Cochrane Library. From the literature review, 6 randomized controlled studies (234 participants) comparing PTENS and standard treatment (urotherapy/anticholinergics) were considered. From each study, the success rates were available for PTENS and the control group. The ratio of success rates was computed-that is, the risk ratio (RR) and the risk difference (RD). RESULTS The overall success rate with PTENS was 1.92 times that of children undergoing standard urotherapy alone (RR: 1.92, 95% confidence interval [CI: 1.02, 3.61]) and 1.56 for those undergoing either urotherapy alone or with pharmacotherapy (anticholinergics; RR: 1.56, 95% CI [1.04, 2.40]). No difference in the success rate was found when PTENS was used in patients failing previous treatment (urotherapy and pharmacological therapy; RR: 0.175, 95% CI [0.02, 1.45]). CONCLUSIONS Current evidence suggests that PTENS is beneficial in children with LUTS. The chance of success is 1.92 times that of children undergoing standard urotherapy. However, in children who have failed urotherapy and pharmacological therapy, PTENS monotherapy has a limited role and should be an adjunct. Literature shortcomings included small numbers of patients, differing inclusion criteria, and PTENS protocols. A need exists for quality multicenter randomized controlled trials to prove the efficacy of PTENS in children with LUTS.

Abstract
INTRODUCTION Transcutaneous parasacral nerve stimulation (TPNS) via electrodes placed over the sacrum can activate afferent neuronal networks noninvasively, leading to sacral reflexes that may improve colonic motility. Thus, TPNS can be considered a promising, noninvasive, and safe method for the treatment of constipation. However, there is no published study investigating its use in children with functional constipation. This is a single-center, prospective, longitudinal, and interventional study designed to assess the applicability and clinical outcomes of TPNS in functionally constipated children. PATIENT CONCERNS Parents or guardians of patients will be informed of the purpose of the study and will sign an informed consent form. The participants may leave the study at any time without any restrictions. DIAGNOSIS Twenty-eight children (7-18 years old) who were diagnosed with intestinal constipation (Rome IV criteria) will be included. INTERVENTIONS The patients will be submitted to daily sessions of TPNS for a period of 4 or 8 weeks and will be invited to participate in semistructured interviews at 3 or 4 moments: 1 week before the beginning of TPNS; immediately after the 4 and/or 8 weeks of TPNS; and 4 weeks after the end of the intervention period. In these appointments, the aspects related to bowel habits and quality of life will be assessed. OUTCOMES This study will evaluate the increase in the number of bowel movements and stool consistency, the decrease in the number of episodes of retentive fecal incontinence, and the indirect improvement in the overall quality of life. CONCLUSION we expect that this study protocol can show the efficacy of this promising method to assist the treatment of children with functional constipation.

Abstract
INTRODUCTION Parasacral transcutaneous electriconeural stimulation (pTENS) is a common treatment modality for patients with overactive bladder (OAB). Its mechanism of effectiveness has yet to be elucidated. Recent studies with fMRI in adults with implanted sacral nerve stimulators impute its effectiveness on changes in the brain involving the anterior cingulate cortex (ACC) and prefrontal cortex (PFC). AIM The study set out to evaluate brain connectivity utilizing functional MRI to the outline the mechanism of action of pTENS in the brain. METHODS Ten adult volunteers without urinary tract symptoms underwent fMRI. Electrodes were placed on the skin at sacral level (S2) (Experimental Stimulation - pTENS) and on the right scapular region (Sham Stimulation - sTENS). Stimulation was done twice on each site for 6 min at a frequency of 10 Hz and pulse width of 260 μs and intensity determined by the motor threshold. A 6 min resting state fMRI was also done twice as control. Functional connectivity data was acquired during each state (resting, pTENS and sTENS). Standard functional connectivity preprocessing was performed. Seed connectivity was examined to investigate changes in ACC functional connectivity between the stimulations and resting-state conditions. Significance was assessed at p < 0.05 corrected for multiple comparisons. RESULTS For all conditions (pTENS, sTENS, and rest), standard patterns of ACC connectivity were detectable with strong connectivity between the ACC and subcortical regions and between the ACC and the frontal lobe. Functional connectivity between ACC seed and the dorsal lateral prefrontal cortex (DLPFC) was significantly increased during pTENS compared to rest. sTENS did not increase connectivity between the ACC seed and DLPFC when compared to rest. DISCUSSION Preliminary results indicate that ACC is a major site of activation during pTENS. Increased connectivity between ACC and DLPFC may be a possible mechanism of pTENS effectiveness, which appears to be specific to pTENS compared to sTENS. This study is limited to the small size at this time which prevents further investigation at other sites in the brain. CONCLUSIONS The study confirms our original aim which was to define if parasacral TENS actually has a central effect.

Impact of transcutaneous interferential electrical stimulation for management of primary bladder neck dysfunction in children. J Pediatr Urol 2020; 16:36.e1-36.e6.

Abstract
INTRODUCTION Several studies have revealed that electrical stimulation is an effective modality for treatment of lower urinary tract (LUT) dysfunction via raising the capacity or compliance of the bladder or maybe by pelvic floor relaxation and reducing detrusor pressure as well. OBJECTIVE This study aimed to assess the efficacy of transcutaneous interferential (IF) electrical stimulation on LUT symptoms as well as urine flow parameters in children with primary bladder neck dysfunction (PBND). STUDY DESIGN We reviewed the charts of all children with persistent LUT symptoms who underwent IF electrical stimulation between 2010 and 2017. Twenty-three neurologically and anatomically normal children (mean age: 7.7 years, range: 5-13) with LUT symptoms were included in this study. Children had different LUT symptoms such as hesitancy, straining, urinary incontinence and constipation with no sufficient response to medical treatment (α -blocker) for at least 6 months. IF electrical stimulation was performed for 15 sessions, two times per week. All children were symptomatic and had abnormal urine flow pattern with an electromyographic (EMG) lag time of more than 6 s on uroflowmetry with EMG. A voiding chart, uroflowmetry with EMG and kidney and bladder ultrasounds were performed before and after the treatment for all children. Maximum and average urine flow rates, EMG lag time and postvoid residual volume were analyzed. In addition, alpha blocker therapy was continued during IF therapy. RESULTS Mean maximum and average urine flow rates improved from 14.1 to 7.6-19.7 ml/s and 9.5 ml/s, respectively, while mean EMG lag time decreased from 11.7 to 5.2 s after the treatment (all P < 0.05). Also postvoid residual volume decreased significantly from 35.6 to 7.6 ml at the end of treatment courses. DISCUSSION Pelvic floor EMG lag time, a documented parameter on uroflowmetry with EMG, defined as the time from the start of pelvic floor relaxation during a volitional voiding effort (the first stage of normal voiding) to the start of urine flow. Results showed that IF therapy decreased pelvic floor EMG lag time in children with PBND. In addition, increase in mean maximum and average urine flow rates in our patients indicated that pelvic IF therapy and behavioral modification improved voiding dysfunction in most of the patients and probably decreased bladder neck activity during voiding. Future studies with larger sample size are needed to support this finding. CONCLUSION IF therapy appears safe, effective and reproducible in improvement of PBND in children.

Abstract
PURPOSE OF REVIEW Pelvic floor physical therapy is a worldwide accepted therapy that has been exclusively used to manage many pelvic floor disorders in adults and children. The aim of this review is to suggest to clinicians an updated understanding of this therapeutic approach in management of children with non-neuropathic voiding dysfunction. RECENT FINDINGS Today, pelvic floor muscle training through biofeedback is widely used as a part of a voiding retraining program aiming to help children with voiding dysfunction which is caused by pelvic floor overactivity. Biofeedback on its own, without a pelvic floor training component, is not an effective treatment. Biofeedback is an adjunct to the pelvic floor training. In the current review, we develop the role of pelvic floor physical therapy in management of children with non-neuropathic voiding dysfunction and compare it with biofeedback therapy alone.

Abstract
AIMS Evaluate the efficacy of biofeedback and parassacral electric nerve stimulation (TENS) for the treatment of children with lower urinary tract (LUT) dysfunction. METHODS A prospective, randomized study was approved by our Hospital Ethics Committee. We enrolled 64 children, 43 girls and 21 boys, average age of 9.39 years. The initial evaluation consisted of history, physical examination, urine analyses, voiding diary, uroflow, and ultrasound. Dysfunction voiding symptom score (DVSS) questionnaires were applied pre- and post-treatment. The children were divided into two treatment groups independent of the predominant type of voiding dysfunction (dysfunctional or overactive bladder): biofeedback group and TENS group. The criteria for assessing the effectiveness of the techniques was the resolution of daytime and nighttime symptoms including urinary leakage, improvements in voiding diary, DVSS, and changes in uroflow. After 6 months, the children were reassessed with the same work-up of baseline. RESULTS Regarding daytime symptoms, results for complete response were similar between the two groups (P = 0.483); 54.9% of children treated by the biofeedback group and 60.6% in the TENS group. The same have been observed in the nighttime incontinence with complete resolutions in 29.6% and 25%, respectively ( P = 0.461). Analyzing the voiding diary, uroflow and DVSS questionnaires both groups had significant improvement ( P = 0.001) after treatment. The biofeedback group required fewer sessions than TENS group, 10.9 and 18.1, respectively ( P < 0,001). CONCLUSIONS Both biofeedback and the TENS are equally effective for treating non-neurogenic voiding dysfunction. Biofeedback seems to require a lower number of sessions to obtain similar results of the TENS.

Abstract
PURPOSE The purpose of this was to evaluate the efficacy (tolerance and safety) of once-a-week parasacral percutaneous electrical nerve stimulation (PENS) to treat overactive bladder (OAB) in children. MATERIALS AND METHODS This is a prospective case series of children aged 4-14 years who underwent PENS for OAB. Acupuncture needles were used bilaterally and symmetrically at S3 for sacral nerve stimulation (Figure). Eighteen children with pure OAB underwent PENS weekly for 20 weeks. Frequency was 10 Hz. Intensity varied up to a maximum of 10 mA, as tolerated by the participant, but without reaching the motor threshold. Pulse width was 600 μs Patients' voiding history was assessed before treatment using a structured questionnaire. The dysfunctional voiding scoring system (DVSS) was used before and after treatment to quantify symptoms of lower urinary tract dysfunction. A visual analog scale (VAS) was used to evaluate treatment outcome. RESULTS Seven boys and eleven girls (mean age, 7.82 ± 2.45 years) were included. According to the VAS, symptoms were resolved in 66% of patients. Urinary urgency, present in all children at baseline, was resolved in 84% (P = 0.001). The proportion of patients with involuntary loss of urine without urgency decreased from 77% before treatment to 27% (P = 0.04). Urge incontinence resolved in 13 of 16 patients after treatment (P = 0.001). Only one of the 12 children with frequent urination at baseline reported this complaint after treatment (P = 0.04). All cases of recurrent urinary tract infection were resolved (P = 0.001). Regarding nocturnal enuresis, treatment was successful in 9 of 14 children (P = 0.004). DISCUSSION The theory behind this new method is that when skin impedance is overcome through the use of acupuncture needles and greater proximity is attained between the tip of the electrode and the sacral nerves, a more effective stimulus is achieved, with enough energy to provide the same benefits as parasacral transcutaneous electrical nerve stimulation with the advantage that treatment can be given only once a week. CONCLUSIONS Percutaneous electrical nerve stimulation seems to be an effective and safe treatment for OAB over the short term. Furthers studies with a control group are needed.

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
BACKGROUND Parasacral transcutaneous electrical nerve stimulation (TENS) has emerged as an effective treatment for overactive bladder (OAB) in view of its high success rates in improving lower urinary tract symptoms and constipation, with no direct side effects. However, the clinical characteristics associated with the outcomes remain to be established. OBJECTIVE The aim of this study was to evaluate potential predictors of outcome in children with OAB treated using parasacral TENS. STUDY DESIGN This was a prospective study of children with symptoms of isolated OAB, enrolled consecutively to the study and treated with parasacral TENS (figure). Isolated OAB was defined as the presence of urinary urgency with no signs of dysfunctional voiding. The symptoms were considered completely resolved when a patient's parents/guardians or the patients themselves reported a 100% improvement. Parasacral TENS was performed twice weekly for a total of 20 sessions of 20 min each at 10 Hz. The potential predictive factors evaluated were: sex, age, daytime incontinence, nocturia, a prior history of urinary tract infection, the presence of nocturnal enuresis, constipation and holding maneuvers. RESULTS Eighty-three patients with a mean age of 7.8 ± 2.8 years were included in the study. Complete resolution of symptoms was achieved in 47 (56.6%). Following parasacral TENS treatment, a significant response was reported in 96.4% of cases. Of the 55 patients with nocturnal enuresis, partial resolution was achieved in 30 cases (54.5%), with a statistically significant association between nocturnal enuresis and the patient's response to treatment (p < 0.004; OR = 4.4, 95% CI 1.5-12.5). No other factor was associated with response to treatment. DISCUSSION To the best of our knowledge, this association between nocturnal enuresis and failure to respond to parasacral TENS treatment for lower urinary tract dysfunction has not previously been reported. The identification of factors capable of predicting therapeutic failure may allow professionals to select those specific patients who would benefit from a multimodal approach in the treatment of this pathology, which has such a significant impact on the quality of life of affected patients. CONCLUSIONS Nocturnal enuresis was the only symptom associated with a poor outcome following parasacral TENS treatment in children with OAB.

Parasacral transcutaneous electrical neural stimulation (PTENS) once a week for the treatment of overactive bladder in children: A randomized controlled trial. J Pediatr Urol 2017; 13:263.e1-263.e6.

Abstract
INTRODUCTION Overactive bladder (OAB) is the most prevalent voiding disorder in childhood, and its main manifestation is urinary urgency. In general, urotherapy and anticholinergics are the first choices of treatment. Parasacral Transcutaneous Electrical Neural Stimulation (PTENS) was introduced as an alternative for the treatment of detrusor overactivity in children, but treatment protocols described to date require several sessions per week or long-lasting sessions, making it difficult for the child to adhere to the treatment. Thus, this study aims to evaluate the effectiveness of PTENS in single weekly sessions in the treatment of OAB in children. STUDY DESIGN This prospective, randomized controlled trial included 16 children with OAB. Children were divided into two groups: CG (urotherapy and electrical stimulation placebo) and EG (urotherapy and PTENS). For both groups, therapy was delivered in 20 weekly sessions, of duration 20 min each. Placebo electrical stimulation was done in the scapular area. The children were evaluated prior to treatment (T1), at the end of the 20 sessions (T2), and 60 days after the completion of treatment (T3), with a 3-day voiding diary, visual analogue scale (VAS), Rome III diagnostic criteria, and the Bristol Scale. RESULTS The groups were similar in age, gender, and ethnicity. In the initial assessment, all children, in both groups, had urgency and incontinence, 50% in each group had constipation, and enuresis was present in seven children (87.5%) in the EG and six (75%) in the CG. No differences were found between the groups regarding the volumetric measurements made in the voiding diary, urinary frequency and constipation evaluated by the Rome III criteria and the Bristol Scale. Sixty days after treatment, a significant improvement was found in the EG group (p = 0.03) regarding urgency (Table), as well as an increase in dry nights in those presenting with enuresis (p = 0.03). No difference was noted regarding urinary incontinence (Table). At the end of 20 sessions and after 60 days of treatment, those responsible for the children in the EG perceived greater improvement in symptoms measured by the VAS (p = 0.05 and 0.04, respectively). CONCLUSIONS Our preliminary results demonstrate that PTENS performed in single weekly sessions is effective in treating the bladder for symptoms of urinary urgency and enuresis, and in the perception of those responsible for the children. Further studies with larger populations are needed to corroborate these results.

Abstract
PURPOSE We evaluated whether combination therapy with transcutaneous electrical nerve stimulation and oxybutynin results in a superior treatment response compared to either therapy alone in children with urge incontinence. MATERIALS AND METHODS In this placebo controlled study 66 children with a mean ± SD age of 7.3 ± 1.6 years who were diagnosed with urge incontinence were randomized to 3 treatment groups. Group 1 consisted of 22 children undergoing transcutaneous electrical nerve stimulation plus active oxybutynin administration. Group 2 included 21 children undergoing active transcutaneous electrical nerve stimulation plus placebo oxybutynin administration. Group 3 consisted of 23 children undergoing active oxybutynin administration plus placebo transcutaneous electrical nerve stimulation. The children received active or placebo transcutaneous electrical nerve stimulation over the sacral S2 to S3 outflow for 2 hours daily in combination with 5 mg active or placebo oxybutynin twice daily. The intervention period was 10 weeks. Primary outcome was number of wet days weekly. Secondary outcomes were severity of incontinence, frequency, maximum voided volume over expected bladder capacity for age, average voided volume over expected bladder capacity for age and visual analogue scale score. RESULTS Combination therapy was superior to oxybutynin monotherapy, with an 83% greater chance of treatment response (p = 0.05). Combination therapy was also significantly more effective than transcutaneous electrical nerve stimulation monotherapy regarding reduced number of wet days weekly (mean difference -2.28, CI -4.06 to -0.49), severity of incontinence (-3.11, CI -5.98 to -0.23) and daily voiding frequency (-2.82, CI -4.48 to -1.17). CONCLUSIONS Transcutaneous electrical nerve stimulation in combination with oxybutynin for childhood urge incontinence was superior to monotherapy consisting of transcutaneous electrical nerve stimulation or oxybutynin, although the latter only reached borderline statistical significance. Furthermore, transcutaneous electrical nerve stimulation was associated with a decreased risk of oxybutynin induced post-void residual urine greater than 20 ml.

Abstract
Both non-invasive and invasive electroneurostimulation (ENS) modalities for bladder bowel dysfunction have been studied and reported in children. A summary of the proposed mechanism of actions and the more commonly used and recently reported techniques and outcomes are described. This includes transcutaneous electrical nerve stimulation, functional electrical nerve stimulation, intravesical electrical nerve stimulation, percutaneous tibial nerve stimulation and sacral neuromodulation in conditions including overactive bladder, enuresis, dysfunctional voiding, constipation, combined bladder bowel dysfunction and neuropathic bladder and bowel dysfunction. There is a need for further high quality randomised trials as well as long-term outcomes to establish whether ENS is able to alter the long-term trajectory for an individual child with bladder bowel dysfunction.

Abstract
AIM To evaluate the immediate effect on natural fill urodynamic parameters and bladder function during transcutaneous electrical nerve stimulation (TENS) in children with overactive bladder (OAB) and daytime urinary incontinence (DUI). MEETHODS In this double-blind, placebo-controlled study, 24 children with severe OAB and DUI (mean age 8.5 ± 1.2 years) underwent 48-h natural fill urodynamics. After 24 h of baseline investigation, the children were randomized to either active continuous TENS (n = 12) or placebo TENS (n = 12) over the sacral S2-S3 outflow. The urodynamic recordings were analyzed manually for three different bladder contraction patterns resulting in a void. The number of bladder contractions not leading to a void was also calculated. Maximum voided volume (MVV) and average voided volume (AVV) were identified for both the baseline and the intervention day. RESULTS We found that TENS had no immediate objective effect on bladder capacity. The difference (before minus after treatment) in MVV/EBC in the active TENS group = 0.03 ± 0.23 versus placebo TENS group = -0.01 ± 0.10 (P = 0.61). Also, there was no significant difference in the proportion of different bladder contraction types between the two groups. TENS did not significantly influence the number of bladder contractions not leading to a void. Results are presented as mean ± SD. CONCLUSION There is no immediate objective effect of TENS on bladder activity assessed by natural fill urodynamics in children with OAB and DUI.

Abstract
OBJECTIVE Neuromodulation has emerged as an effective therapeutic option for treatment of OAB in children. However, to our knowledge, no study has yet evaluated the results of neuromodulation on a session-by-session basis. The aim of this study was to evaluate the rate of complete response of overactive bladder (OAB) symptoms for each session of transcutaneous electrical stimulation (TENS), in a protocol of 20 sessions of therapy. METHOD This is a prospective study of the improvement of LUTS in children with isolated OAB. Included in this study were children over the age of 4 years who complained of urinary urgency, had bell-or tower-shaped uroflowmetry patterns, and post-void residual <10% of expected capacity for their age and/or less than 20 mL. No patient was treated with an anticholinergic. Children were excluded with lower urinary tract symptoms (LUTS) secondary to urinary tract abnormalities. All patients underwent parasacral transcutaneous neurostimulation (TENS). The development of symptoms was observed right before each session using a visual analog scale (VAS) in which 0 means the absence of improvement and 10 represents maximum improvement of symptoms. RESULTS We noted a complete resolution of symptoms (urgency, urge incontinence, frequency, and holding maneuvers) in some patients starting after the third session. In the 10th and 20th (last) sessions, 12 (17.4%) and 38 (55.1%) patients reported a complete resolution of symptoms. After complete resolution, 12 (17.4%) patients reported that their symptoms worsened to a minimum level of 40% improvement, but this was temporary and all returned to 100% improvement. Children who showed an improvement level greater than 50% in the fifth treatment session were 4.18 (p = 0.007) times more likely to have success in the last treatment session. CONCLUSION We found that a patient can experience complete symptom resolution as quickly as following the third session of TENS. The complete response rate progressively increases with the number of sessions, slowly until the 12th session and more rapidly after that. When symptom improvement of at least 50% is reported in the fifth session, there is a higher chance that the patient will have full resolution of symptoms at the end of treatment.

Abstract
Non-neurogenic lower urinary tract dysfunction (LUTD) in children is very common in clinical practice and is important as an underlying cause of lower urinary tract symptoms, urinary tract infection and vesicoureteral reflux in affected children. LUTD in children is caused by multiple factors and might be related with a delay in functional maturation of the lower urinary tract. Behavioral and psychological problems often co-exist in children with LUTD and bowel dysfunction. Recent findings in functional brain imaging suggest that bladder bowel dysfunction and behavioral and psychiatric disorders in children might share common pathophysiological factors in the brain. Children with suspected LUTD should be evaluated properly by detailed history taking, validated questionnaire on voiding and defecation, voiding and bowel diary, urinalysis, screening ultrasound, uroflowmetry and post-void residual measurement. Invasive urodynamic study such as videourodynamics should be reserved for children in whom standard treatment fails. Initial treatment of non-neurogenic LUTD is standard urotherapy comprising education of the child and family, regular optimal voiding regimens and bowel programs. Pelvic floor muscle awareness, biofeedback and neuromodulation can be used as a supplementary purpose. Antimuscarinics and α-blockers are safely used for overactive bladder and dysfunctional voiding, respectively. For refractory cases, botulinum toxin A injection is a viable treatment option. Prudent use of urotherapy and pharmacotherapy for non-neurogenic LUTD should have a better chance to cure various problems and improve self-esteem and quality of life in affected children.

Abstract
OBJECTIVES Neurostimulation is increasingly used in treating bladder and bowel dysfunction, but its effect on rectal motility is obscure. The aim of the study was to evaluate the acute effect of transcutaneous electrical nerve stimulation (TENS) on rectal motility in children with overactive bladder (OAB). METHODS In this double-blind placebo-controlled study in 20 children with OAB (mean age 8.6 ± 1.8 years; 7 girls), 48-hour urodynamic monitoring including rectal manometry was performed. After 24-hours of baseline investigation without stimulation the children were randomised to either active TENS (n = 10) or placebo (n = 10). Surface electrodes were placed over the sacral bone. The exterior of active and placebo stimulators was identical. Starting in the morning, the children received either continuous TENS stimulation or placebo until bedtime. Rectal contractions were defined as pressure runs exceeding 5 cm H2O and lasting ≥3 minutes. RESULTS At baseline there was no significant difference in proportion of time with rectal contractions in the 2 groups (TENS group median 31% [range 12%-66%] vs placebo group median 31% [range 10%-66%]; P = 0.75); however, on the day of stimulation there was more time with rectal contractions in the group receiving TENS (median 51% [range 25%-78%]) compared with placebo (median 32% [range 4%-68%]; P = 0.02). Also, there was an increase in time with rectal contractions in the TENS group (P = 0.007) but not in the placebo group (P = 0.39). The night after the TENS was disabled, rectal activity in both groups returned to baseline level. CONCLUSIONS TENS acutely increases time with rectal contractions in children undergoing urodynamic investigation. The effect disappears when the stimulator is turned off.

Abstract
OBJECTIVE To evaluate the urodynamic changes immediately after the first session (acute effect) and after the last session of parasacral TENS in children with idiopathic OAB. MATERIALS AND METHODS We performed urodynamic evaluation immediately before and after the first session of parasacral TENS and immediately after the last session (7 weeks later). Only children with idiopathic isolated OAB were included. Patients with dysfunctional voiding were not included. RESULTS 18 children (4 boys and 14 girls, mean age of 8.7) were included in the first analysis (urodynamic study before and immediately after the first session) and 12 agreed to undergo the third urodynamic study. Urodynamic before and immediately after the first session: There was no change in the urodynamic parameters, namely low MCC, low bladder compliance, presence of IDC, the average number of IDC, or in the maximum detrusor pressure after the first exam. Urodynamic after the last session: The bladder capacity improved in most patients with low capacity (58% vs. 8%). Detrusor overactivity was observed in 11 (92%) before treatment and 8 (76%) after. There was not a significant reduction in the average number of inhibited contractions after TENS (p=0.560) or in the detrusor pressure during the inhibited contraction (p=0.205). CONCLUSION There was no change in the urodynamic parameters immediately after the first session of stimulation. After the last session, the only urodynamic finding that showed improvement was bladder capacity.

Abstract
OBJECTIVE To assess the objective efficacy of transcutaneous posterior tibial nerve stimulation in children presenting with overactive bladder resistant to well conducted treatment. MATERIAL AND METHOD This was a randomized, double-blind, controlled study on 20 children with OAB. All patients were previously treated with anticholinergic drugs associated with detrusor rehabilitation, diet advice, bladder-voiding hygiene and constipation treatment, with poor clinical results. Patients were randomized into two groups: -Group A: treatment with PTNS (n = 11). -Group B: sham treatment (n = 9). The program lasted 12 consecutive weeks with two 30-minutes sessions a week. Each patient underwent pre-stimulation urodynamic testing to validate bladder overactivity followed by a post-stimulation testing. Pre- and post-stimulation urodynamic parameters were compared in order to objectively evaluate the treatment's efficacy. The patients noted their incontinence episodes for 7 consecutive days in a diary before the beginning of the program, in the middle and at the end of it: this led to computing an incontinence score (score ranged from 0 to 13, from good to poor). The difference between the pre-stimulation and post-stimulation score enabled to express clinical results in terms of poor (less than a 3-point decrease), medium (a 3 to 5-point decrease), good (6 to 8-point decrease), very good (final score ranged between 0 and 3). Children were questioned regarding their impression of being stimulated or not. RESULTS In Group A, there were five very good clinical results (45%), one medium (10%) and five poor results (45%). In group B, nine very good results (66%) and three poor results (33%) were noted. Regarding urodynamic testing, volume voided during urgency (184 mL to 265 mL), maximal cystomanometry volume (215 mL to 274 mL) and volume at the onset of the first overactive detrusor contraction (ODC) (48 mL to 174 mL) were significantly increased in Group A (p = 0.002, p = 0.024 and p = 0.001) and maximal bladder pressure during ODC had decreased (61 to 46) (p = 0.042). 85% children in group A thought they were being stimulated vs. 70% in group B. CONCLUSION Even though we noticed urodynamics improvements in group A, which objectively supports the efficacy of TCTPNS, clinical results remained the same between the two groups. In spite of the small size of our sample, this underlines the placebo effect of any type management in this pediatric population. Studying precisely the maximal useful voltage and duration of stimulation should then be relevant in order to yield maximal benefits from this easy-to-use procedure.

Abstract
OBJECTIVE While there are many options for children with treatment refractory urinary incontinence, there is no single accepted method. This study's aim was to prospectively evaluate the effect of transcutaneous electrical nerve stimulation in children with urinary incontinence resistant to standard medical, urological therapy and/or biofeedback. PATIENTS & METHODS This study was performed at a university hospital. For inclusion, patients >5 years of age first underwent evaluation with urinary ultrasonography, uroflow-electromyogram and voiding diaries. Treatment with biofeedback, alpha adrenergic blockers, anticholinergics and/or urotherapy was commenced according to uroflow-EMG and voiding diary findings. Patients with partial or no response to this standard therapy were then included in this study, performed between April 2012 and February 2014. Patients with anatomical or neurological causes for urinary incontinence were excluded. TENS was performed on S3 dermatome, every day for 3 months. Each session lasted 20 min with a frequency of 10 Hz and generated pulse of 350 μs. Intensity was determined by the child's sensitivity threshold. Medical treatment and urological therapy was continued during TENS. Uroflow parameters (voiding volume as percentage of expected bladder capacity, Qmax, Qave, flow and voiding time, postvoiding residual urine) and urinary system symptoms (presence of urinary tract infection, frequency, urge incontinence, fractionated voiding and constipation) were compared immediately before commencement and immediately after the completion of 3 months of TENS. RESULTS Twenty-seven patients were included in this study (4 males, 23 females). Patients' average age was 7.2 years, 11 had overactive bladder and 16 had dysfunctional voiding. Comparison of urinary system symptoms and uroflow parameters before and after TENS are shown in Table. After 3 months of TENS; a statistically significant decrease was observed in the number of patients with frequency, urge incontinence, urinary tract infections and constipation. There was a decrease in the number of patients with fractionated voiding, although this change was not statistically significant. Similarly, for uroflow-EMG parameters; bladder capacity, Qmax, Qave and flow time increased while voiding time and PVR decreased. Changes seen in bladder capacity, Qmax and PVR were statically significant, while other changes were not. Patients' response rates after 3 months of TENS were; complete response in 70.4%, partial response in 22.2% and no response in 7.4%. CONCLUSION This study has shown that transcutaneous electrical nerve stimulation is a promising treatment option for standard-treatment refractory children with urinary incontinence.

Abstract
INTRODUCTION The purpose of this study was to evaluate safety and tolerability of transcutaneous tibial nerve stimulation (TENS) in patients under 15years of age with refractory overactive bladder. MATERIALS AND METHODS A retrospective analysis was conducted on outcomes of TENS (1daily 20-minute session, 10Hz) in patients with refractory overactive bladder, excluding patients with neurogenic bladder. Treatment efficacy was evaluated on symptomatic improvement and voiding schedule. Healing was defined as following: no recurrence of urinary tract infection, normal urodynamic voiding parameters, no nighttime continence disorder, normal uroflowmetry. RESULTS Nineteen consecutive patients with refractory overactive bladder were treated from November 2010 to March 2012 (11girls, 8boys, age 12.1±2.7 years). Three patients reported only daytime voiding disorders, the others reported daytime and nighttime voiding disorders. Ten patients reported febrile urinary tract infection (1 boy, 9 girls). The average length of treatment was 6 months. Two patients were lost to follow-up. Thirteen patients had only tibial TENS; 3 patients had tibial TENS and trospium chloride or desmopressin. At 1-month assessment, 16 patients out of 17 (94%) reported symptomatic improvement. At the end of treatment, 12 patients out of 17 (70%) met healing criteria (5 boys, 7girls), without relapse within 9 months. Three boys (18%) had partial improvement (no daytime wetting, but increased daytime frequency). No patient reported side effects. CONCLUSION Tibial TENS is a safe, non invasive and effective treatment in refractory overactive bladder in children. The success rate is 70%, with no side effect and no relapse at the end of the treatment in our study.

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.

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.

Abstract
PURPOSE Parasacral transcutaneous electrical nerve stimulation and posterior tibial nerve stimulation have emerged as effective methods to treat overactive bladder in children. However, to our knowledge no study has compared the 2 methods. We evaluated the results of parasacral transcutaneous electrical nerve stimulation and posterior tibial nerve stimulation in children with overactive bladder. MATERIALS AND METHODS We prospectively studied children with overactive bladder without dysfunctional voiding. Success of treatment was evaluated by visual analogue scale and dysfunctional voiding symptom score, and by level of improvement of each specific symptom. Parasacral transcutaneous electrical nerve stimulation was performed 3 times weekly and posterior tibial nerve stimulation was performed once weekly. RESULTS A total of 22 consecutive patients were treated with posterior tibial nerve stimulation and 37 with parasacral transcutaneous electrical nerve stimulation. There was no difference between the 2 groups regarding demographic characteristics or types of symptoms. Concerning the evaluation by visual analogue scale, complete resolution of symptoms was seen in 70% of the group undergoing parasacral transcutaneous electrical nerve stimulation and in 9% of the group undergoing posterior tibial nerve stimulation (p = 0.02). When the groups were compared, there was no statistically significant difference (p = 0.55). The frequency of persistence of urgency and diurnal urinary incontinence was nearly double in the group undergoing posterior tibial nerve stimulation. However, this difference was not statistically significant. CONCLUSIONS We found that parasacral transcutaneous electrical nerve stimulation is more effective in resolving overactive bladder symptoms, which matches parental perception. However, there were no statistically significant differences in the evaluation by dysfunctional voiding symptom score, or in complete resolution of urgency or diurnal incontinence.

Abstract
PURPOSE Our aim was to evaluate the efficacy of our treatment program for children with lower urinary tract conditions, developed at the Department of Pediatric Nephrology of the University Children's Hospital in Ljubljana. METHODS Sixty-four patients with lower urinary tract conditions were randomly allocated to two groups. Group A received treatment immediately, whereas patients of group B received no treatment for a period of 3 months-the amount of time it takes to complete our program. No child in group B experienced spontaneous regression of their symptoms in the 3-month delay period, while the patients of group A were already being treated and were achieving results. Thus, all the patients of group B then entered the program in exactly the same way as patients of group A. RESULTS The final success rate in both groups did not differ significantly (p = 0.706-1.000) and ranged from 86.2 % for group A and 86.7 to 90 % for group B. Long-term follow-up showed statistically identical success rates (p = 1.000). CONCLUSION This prospective controlled study with long-term follow-up (48 months) shows that our treatment program, applied as an inpatient voiding school program, is an effective method, with durable results.

Abstract
PURPOSE Sacral nerve modulation with an implantable pulse generator is not an established treatment in children. This therapy has been described for dysfunctional elimination syndrome and neurogenic bladder. We report 2 new indications for this approach in children, ie bladder overactivity and Fowler syndrome. The aim of this study was to improve the results of future treatment for sacral neuromodulation in children by describing factors favorable for good outcomes with this method. MATERIALS AND METHODS A total of 18 children 9 to 17 years old were studied. Mean ± SD followup was 28.8 ± 43.8 months. Of the patients 16 underwent S3 sacral neuromodulation and 7 underwent pudendal stimulation (5 as a revision, 2 from the beginning). RESULTS Initial full response was achieved in 9 of 18 patients (50%) and partial response in 5 (28%). In patients presenting with incontinence mean ± SD number of incontinence episodes weekly improved significantly from 23.2 ± 12.4 to 1.3 ± 2.63 (p <0.05). In patients requiring clean intermittent catheterization there was a significant decrease in mean ± SD daily frequency of catheterization from 5.2 ± 1.6 to 2.0 ± 1.9 (p <0.05). At the end of the study 6 of 15 patients (40%) had a full response and 5 (33%) had a partial response, while 4 implantable pulse generator devices (27%) were explanted because of failure. CONCLUSIONS Sacral neuromodulation is feasible in the pediatric population, with good short-term (78% full or partial response) and satisfactory long-term results (73%). Sacral neuromodulation can offer good results for overactive bladder, dysfunctional elimination syndrome and Fowler syndrome. Pudendal nerve stimulation is a feasible salvage treatment that can be useful in cases when S3 implantation is impossible or unsuccessful.

Abstract
AIMS To review studies using electrical neural stimulation (ENS), to treat children with non-neurogenic lower urinary tract dysfunctions (LUTD), and to establish the efficacy of this treatment. METHODS This review was based on an electronic search of the MEDLINE database and the Cochrane Central Search library, from January 1990 to March 2010. INCLUSION CRITERIA (1) participants aged 0-17 years, (2) participants with a diagnosis of LUTD not related to congenital abnormalities or neurological disease, (3) English language, and (4) treatment by ENS. RESULTS Seventeen papers were evaluated. Type of ENS varied among studies: sacral transcutaneous ENS in seven, sacral implanted device in four, posterior tibial percutaneous in three, and anogenital, endoanal, and intravesical in one each. There were two randomized clinical trials. Clarity regarding the LUTD being treated was variable. The populations studied were not homogeneous. The duration of treatment and the number of sessions a week were variable among the studies. Electrical parameters used also varied. A range of subjective and objective measures was used to measure treatment success. Rates of complete resolution of the symptoms of OAB, urgency, and daytime incontinence ranged from 31% to 86% [Trsinar and Kraij, Neurourol Urodyn 15: 133-42, 1996; Hagstroem et al., J Urol 182: 2072-8, 2009], 25% to 84% [Hoebeke et al., J Urol 168: 2605-8, 2002; Lordêlo et al., J Urol 182: 2900-4, 2009], 13% to 84% [Malm-Buatsi et al., Urology 70: 980-3, 2007; Lordêlo et al., J Urol 184: 683-9, 2010], respectively. For sacral transcutaneous ENS recurrence ranged from 10% to 25%. Apart from the sacral implantation studies, any reported side effects were mild and transitory. CONCLUSIONS The literature in the area of interest is sparse. Parasacral TENS has been shown to be more effective than sham in randomized trials in treating OAB. This deserves further research to elucidate the optimal parameters and the children for whom it is most useful.

Abstract
Overactive bladder (OAB) is a urological condition that is frequently observed in children and requires treatment. Standard urotherapy is usually the first line of treatment; however, children with severe OAB do not respond to this therapy. Antimuscarinic drugs may be used, but complete resolution of symptoms with this medication is low. Studies, including two randomized clinical trials, have demonstrated that electrical nerve stimulation (ENS) can be used successfully for OAB in children. Electrodes have been placed in the genitals, anus, and intravesical area, and on the tibial posterior nerve, as well as used transcutaneously or implanted during a surgical procedure. This Review will discuss the use of ENS in children with OAB, with particular focus on the putative mechanisms of action, the different ENS techniques available, and clinical results for this therapy.

Abstract
PURPOSE A variety of electrical nerve stimulation methods has been used through the years to treat lower urinary tract dysfunction. Relevant literature was reviewed to analyze techniques and available biomedical devices, technique applicability, indications and usefulness in pediatrics. MATERIALS AND METHODS An extensive search was performed on PubMed® and MEDLINE® for scientific publications on intravesical, transcutaneous, sacral spine and root, and tibial nerve stimulation in children with lower urinary tract dysfunction of nonneurogenic and neurogenic origin. Relevant articles and controlled studies in adult patients were also considered. The search covered the period 1990 to 2009 and we found approximately 400 articles, of which 29 related to pediatrics. RESULTS Due to feasibility problems with placebo studies the majority of the studies were noncontrolled, some of them clinical trials on acute urodynamic changes during electrical stimulation or experimental research in animals. Overall only a few randomized trials were found. Regarding types of electrostimulation and indications in children the recent literature emphasizes stimulation far from the anal-genital region, such as sacral transcutaneous electrical nerve stimulation, mainly for refractory overactive bladder. Intravesical stimulation is the procedure of choice to enhance sensation in patients with incomplete neurogenic lesions. Percutaneous tibial nerve stimulation is tolerated by children but has been poorly studied. Sacral neuromodulation using implanted devices remains questionable and needs further clarification of its indications. Magnetic stimulation has rarely been used in children to date. More experimental studies are needed to assess the method of action and refine the parameters of stimulation. CONCLUSIONS Clinical controlled trials vs sham devices and predictable variables for successful response are urgently needed to address an apparently renewed focus on the use of nerve stimulation in the treatment of pediatric lower urinary tract symptoms.

Abstract
PURPOSE We evaluated the effectiveness of parasacral transcutaneous electrical nerve stimulation to treat overactive bladder in children. We designed a prospective randomized trial with sham control for this evaluation. MATERIALS AND METHODS We prospectively randomized 25 girls and 12 boys with an average age of 7.6 years (range 4 to 12) into the test (active treatment) or sham (superficial scapular electrical stimulation) group. A total of 20 sessions, 20 minutes each (10 Hz) were performed 3 times weekly. The criteria used to evaluate the rate of success were 1) self-reported cure, or significant, mild or no improvement; 2) visual analogue scale (level of success 0 to 10); 3) percent improvement; 4) modified Toronto score; and 5) maximum voided volume, average voided volume and number of voids daily based on bladder diary entries. After completion of the 20 sessions controls who were not cured underwent active treatment. RESULTS A total of 21 patients in the test group and 16 in the sham group underwent treatment. Among the active treatment group 61.9% of parents reported cure. In the sham group no parent reported cure (p <0.001). Regarding visual analogue scale a score of 10 was indicated by 13 parents in the test group, while 1 parent in the sham group indicated a score of 9 (p = 0.002). Additionally 100% improvement was reported by 12 parents in the test group and no parent in the sham group. Toronto score improved significantly in the test group (p <0.001) and sham group (p = 0.008). However, the score was reduced more significantly in the test group compared to the sham group (p = 0.011). In the test group average and maximum voided volumes showed a statistically significant increase and the number of voids daily decreased. After superficial scapular electrical stimulation 13 of the 16 patients who underwent parasacral transcutaneous electrical nerve stimulation were cured. CONCLUSIONS This is the first known randomized clinical trial to demonstrate that parasacral transcutaneous electrical nerve stimulation is effective in the treatment of children with overactive bladder.

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
OBJECTIVES To investigate afferent pathway dysfunction in children with primary nocturnal enuresis by measuring pudendal somatosensory evoked potential and tibial somatosensory evoked potential. METHODS Subjects with primary nocturnal enuresis, 36 boys and 18 girls, aged from 5 to 16 years, were enrolled in this study: 24 subjects had complicated primary enuresis (CPE) and 30 subjects had monosymptomatic primary enuresis (MPE). There were no differences in bodyweight or gender between the MPE and CPE groups (P > 0.05). All of the children underwent physical examination, urine analysis, urinary ultrasound and spinal magnetic resonance imaging. Only subjects without urological and neurological abnormalities (with the exception of spina bifida occulta, which was found in some of the patients) were included in this neurophysiological study. RESULTS There were 20 children who were positively recorded with pudendal somatosensory evoked potential in the CPE group, and all of the children in the MPE group were positively recorded (P < 0.05). Positive records of tibial somatosensory evoked potential were successfully achieved in both groups. Furthermore, the pudendal and tibial conductive velocity were slower as compared to the normal range, especially in children in the CPE group (P < 0.001). CONCLUSIONS Afferent pathway function may be impaired by some factors, which should be considered by both clinicians and parents.

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.
