One-day voiding diary in the evaluation of Lower Urinary Tract Symptoms in children.

INTRODUCTION: Voiding diary (VD) is an important tool in the evaluation of children with voiding symptoms. Voiding frequency, maximal voided volume (MVV), average voided volume (AVV) and nocturnal volume (NV) can be extracted and are valuable in diagnosing and monitoring these disorders. Recently, ICCS has reduced the period of data recording on VD from 3 to 2 days.We hypothesized that one day voiding diary would be enough for guiding treatment. MATERIALS AND METHODS: Children with overactive bladder (OAB) and primary monosymptomatic enuresis (PMNE) were oriented to fulfill a 3-day VD. Data obtained from VD were evaluated for the first day (1dVD), the first two days (2dVD), and all 3 days (3dVD) and compared according to the MVV, AVV, frequency, NV and expected bladder capacity (EBC). The Friedman, Student's t test and the Fisher's exact was used. ANOVA was used for multiple comparisons. We also used Pearson correlation test. RESULTS: Ninety-eight children were included, 59 had PMNE and 30 OAB. Frequency, AVV and VN were similar regardless how many days the voiding episodes were recorded. Only MVV was higher by a mean of only 32 mL on 3dVD compared to 1dVD. A 1dVD has a sensitivity of 93,9% and a positive likelihood ratio of 2.2. As for the correlation of MVV and EBC it was observed that in 83% of children, MVV was lower than EBC. MVV corresponds to 67% and 69% of EBC in children with PMNE and OAB, respectively. CONCLUSION: We believe that 1dVD is sufficient to assess these children. It has a high sensitivity and good correlation to 3dVD in evaluating these children. Bladder capacity in this population, evaluated by maximum voided volume, was close to 68% of that obtained by the EBC.

Enuresis and upper airway obstruction: BNP and ADH hormones behavior before and after airway surgery.

INTRODUCTION: Upper airway obstruction (UAO) is a common condition in all pediatric population, with a 27% prevalence. Primary monosymptomatic nocturnal enuresis (PMNE) is a condition related to UAO in 8% to 47% of these children. The specific pathophysiological mechanism of this bond is not well understood. Some authors suggest a connection between brain natrituretic peptide (BNP) and anti-diuretic hormone (ADH) during sleep. The aim of this study was to evaluate hormone profile (ADH and BNP) and improvement in dry nights in a sample of children before and after surgical treatment of the UAO. METHODS: This is a longitudinal prospective interventionist study in children, 5 to 14 years of age, with UAO and PMNE recruited in a specialty outpatient clinic. Children presenting UAO and PMNE were evaluated with a 30-day dry night diary and blood samples were collected to evaluate ADH and BNP before and after upper airway surgery. Data were analyzed prior to surgery and 90-120 days after surgery. RESULTS: Twenty-one children with a mean age of 9.7 years were included. Mean BNP before surgery was 116.5 ± 126.5 pg/mL and 156.2 ± 112.3 pg/mL after surgery (p<0.01). Mean ADH was 5.8 ± 3.2 pg/mL and 14.6 ± 35.4 before and after surgery, respectively (p=0.26). The percentage of dry nights went from 32.3 ± 24.7 before surgery to 75.4 ± 33.4 after surgery (p˂0.01). CONCLUSION: Surgery for airway obstruction contributed to an increase in BNP without increasing ADH. A total of 85.8% of the children presented partial or complete improvement of their enuresis.

Psychological Intervention with Parents Improves Treatment Results and Reduces Punishment in Children with Enuresis: A Randomized Clinical Trial.

PURPOSE: This study aims to evaluate the impact of psychological intervention with parents of children with enuresis on treatment outcome. MATERIALS AND METHODS: A total of 66 children with enuresis were randomized into 2 groups. All children received urotherapy orientation and psychological counseling. Psychological intervention was performed with parents in the experimental group and not in the control group. All parents answered a questionnaire to evaluate violence against their children (Parent-Child Conflict Tactics Scale) and the Tolerance Scale. The Child Behavior Checklist was applied to evaluate behavior problems. Children responded to the Impact Scale and the Children and Youth Self-Concept Scale. Treatment results were assessed with a 14-day wet night diary. RESULTS: Mean age and gender were similar in both groups. Parent-Child Conflict Tactics Scale showed less violence after the treatment in the experimental group (p=0.007). The Tolerance Scale indicated that parents of children with enuresis were intolerant and that, after treatment, intolerance had a greater decrease in the experimental group (p <0.001). The Impact Scale showed that children suffer some impact from enuresis, and that in those in the experimental group this impact was smaller after treatment (p=0.008). No differences were seen in the Child Behavior Checklist or Children and Youth Self-Concept Scale after intervention. After treatment the percentage of dry nights had a greater improvement in the experimental group (52%, range 30% to 91%) than in the control group (10%, range 3% to 22.5%; p <0.001). Children in the experimental group had a 6.75 times greater chance of having a complete response to treatment. CONCLUSIONS: Psychological intervention with parents of children with enuresis during their treatment improved the percentage of dry nights and the impact of enuresis, while their parents started coping better with the problem and became more tolerant, reducing punishment toward their children.

Echocardiographic evaluation of left ventricular mass index in children with hypospadias after hormonal stimulation with topical testosterone: A randomized controlled trial.

INTRODUCTION: Testosterone is often used in the preoperative period of hypospadias surgery. Previous studies have demonstrated the presence of androgen receptors in cardiac myocytes that can modulate the phenotype. The use of supraphysiological doses of androgens can lead to toxicity on the heart muscle and, in some cases, to left ventricular hypertrophy. This randomized double blind controlled clinical trial aims to evaluate the effect of topical testosterone on left ventricular mass index in boys with hypospadias. MATERIALS AND METHODS: Boys with hypospadias aged 6 months to 9 years were included. Children were divided into two groups: G1 - boys who received testosterone propionate 1% ointment twice a day for 30 days, and G2 - boys receiving placebo ointment in the same regimen. All children were submitted to bi-dimensional echocardiographic evaluation to compare the left ventricular mass index, blood pressure, and body mass index before and after treatment (30 and 90 days). Levels of serum testosterone, LH, and FSH were measured. RESULTS: Thirty-five children were analyzed: 17 in G1 and 18 in G2. No differences were found in left ventricular mass index (left ventricular mass indexed by body surface area) prior to treatment. Left ventricular mass index was 59.21 ± 11.91 g/m2 in G1 and 55.12 ± 8.29 g/m2 in G2 (p = 0.244) after 30 days of treatment, and 61.13 ± 11.69 g/m2 in G1 and 62.84 ± 35.99 g/m2 in G2 (p = 0.852) after 90 days. Serum testosterone levels were 12 (7-80) ng/dL in G1 and 5 (5-7) ng/dL in G2 (p = 0.018) after 30 days of treatment, and 10 (5-11) ng/dL in G1 and 5 (4-5) ng/dL in G2 (p = 0.155), after 90 days (Figure). There was a small increase in systolic blood pressure (SBP) after 30 days (83.82 ± 7.18 mmHg) in the group who receive testosterone (G1) compared with controls (77.5 ± 6.69 mmHg) (p = 0.010). After 90 days, SBP levels returned to basal levels in G1 (82.35 ± 5.62 mmHg) and in G2 (81.38 ± 4.79 mmHg) (p = 0.588). CONCLUSION: Topical testosterone can be considered safe in the preoperative period of children with hypospadias with no risk of left ventricular hypertrophy. An increase in systolic blood pressure occurs while using testosterone but it is transitory, returning to normal levels after 90 days.

Parasacral transcutaneous electrical neural stimulation (PTENS) once a week for the treatment of overactive bladder in children: A randomized controlled trial.

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.

Increased Risk of Physical Punishment among Enuretic Children with Family History of Enuresis.

PURPOSE: Some parents blame their children for bedwetting and, therefore, punish them. This study aimed to assess the rate of punishment experienced by enuretic children and associated causative factors. MATERIALS AND METHODS: A total of 87 children 6 to 15 years old with monosymptomatic enuresis were assessed individually. Parents answered the questions in the tolerance scale. The forms of punishment were classified as verbal, chastisement and physical aggression. Family history of enuresis was considered only when 1 or both parents had experienced enuresis. RESULTS: Of the 35 girls and 52 boys with a mean ± SD age of 9.3 ± 2.3 years 67 had a family history of enuresis. Of the 67 parents 57 (85.0%) had a history of being punished due to enuresis. All children experienced some sort of verbal punishment. Children who had a family history of enuresis were more prone to being punished by physical aggression than those without such a family history (32 of 67 or 47.8% vs 4 of 20 or 20%, OR 3.7, 95% CI 1.1-12.1, p = 0.03). Punishment was found 3 times more frequently in girls than in boys (20 of 35 or 57.1% vs 16 of 52 or 30.8%, OR 3.0, 95% CI 1.2-7.3). Parents of 79 of the 87 children (90.8%) had high scores on the tolerance scale regardless of the history of enuresis. CONCLUSIONS: Enuretic children are at a high risk for experiencing some kind of punishment. Children whose parents had enuresis are at risk for being physically punished. Parents should be taught about the involuntary nature of enuresis and the fact that no punishment would help improve the condition.

Association between Asthma and Primary Nocturnal Enuresis in Children.

PURPOSE: Enuresis, sleep respiratory disorders and asthma compromise the quality of sleep in children and may occur in association with each other. An association between sleep respiratory disorders and enuresis has already been demonstrated. According to united airways disease abnormalities of the upper and lower airways may coexist. A child who wheezes has a greater chance of snoring and having obstructive sleep apnea. Since asthma and sleep respiratory disorders may be associated, and sleep respiratory disorders are associated with enuresis, we determined the possibility of an association between asthma and enuresis. MATERIALS AND METHODS: Between August 20 and March 2015 parents/guardians of children 6 to 14 years old from 16 elementary schools in our area were randomly chosen for study. Children with nonmonosymptomatic enuresis and urological or neurological disease were excluded. The Tucson and ISAAC (International Study of Asthma and Allergies in Childhood) questionnaires were used to assess sleep respiratory disorders and asthma, respectively. RESULTS: A total of 523 children (283 males and 240 females) with a mean ± SD age of 9.42 ± 2.46 years were included in analysis. The overall prevalence of enuresis was 15.87% (95% CI 12.98-19.26). Asthmatic children with wheezing in the last 12 months were 2.33 times more likely to have had enuresis at some point in life (OR 2.33, 95% CI 1.37-3.95, p = 0.0017). If enuresis was present, the chance increased to 2.78 (95% CI 1.38-5.61, p = 0.0041). Enuretic children were 5.34 times more prone to have apnea reported by parents (95% CI 2.19-13.03, p = 0.0002). CONCLUSIONS: These findings demonstrate that asthma as well as sleep respiratory disorders is associated with primary nocturnal enuresis.

Association between exclusive maternal breastfeeding during the first 4 months of life and primary enuresis.

INTRODUCTION: Although the relationship between enuresis and breastfeeding is still poorly documented in the literature, a possible association is speculated as both are strongly associated with children's development. Therefore, the main objective of this study was to evaluate whether there is an association between primary enuresis and the duration of exclusive breastfeeding. MATERIAL AND METHODS: This is an observational, case-control study, involving 200 children and adolescents from 6 to 14 years old, who were divided into two groups: the enuresis group (EG), composed of 100 children with primary enuresis; and the control group (CG) of 100 matched children without enuresis. The matching criteria were sex, age, and socioeconomic level. Adults responsible for each infant answered a structured questionnaire to identify biological and behavioral factor, as well as the duration of maternal breastfeeding. Children whose parents could not comprehend the questionnaire or children with neurological or psychiatric disorders or secondary enuresis were not included in the study. RESULTS AND DISCUSSION: Evaluating the duration of exclusive breastfeeding, 72% of the subjects of the EG and 42% of the CG had been breastfed for less than 4 months (p < 0.001) (Figure). In bivariate analysis, there was a strong association between symptoms of enuresis with a positive family history of enuresis and duration of exclusive breastfeeding (p < 0.001), and also association with full breastfeeding duration (p = 0.044), number of children (p = 0.045), and parents' education (p = 0.045). After logistic regression, primary enuresis continued to be associated with duration of exclusive breastfeeding and family history of enuresis. The proportion of children that had been exclusively breastfed for more than 4 months was significantly higher in the CG 58% (58/100) than in the EG 28% (28/100) (p < 0.001, OR 4.35, 95% CI 1.99-9.50). CONCLUSIONS: This study confirmed the association between primary enuresis and various factors that have already been studied, with the addition of a new factor, duration of exclusive breastfeeding for less than 4 months, which is strongly associated with primary enuresis.

Prevalence of lower urinary tract symptoms in individuals with Down syndrome.

OBJECTIVES: Down syndrome (DS), which is caused by the trisomy of chromosome 21, is the most frequent of all genetic syndromes. The current study aims to estimate the prevalence of lower urinary tract symptoms (LUTS) in individuals with DS buy using the Dysfunctional Voiding Symptom Score (DVSS) and correlate with functional constipation, age, and gender, as well as determine the most sensitive and specific factors associated with LUTS. METHODS: LUTS was assessed in individuals with DS using a cross-sectional study through the application of a validated and adapted version of the DVSS for the Brazilian population. The presence of functional constipation was evaluated according to the Rome III criteria. RESULTS: Of the 114 individuals assessed, 84 were included in the study (median age 16 ± 5.0 years, 66.7% female). The prevalence of LUTS was 27.3%. The symptoms were more frequent in males (OR 3.0, 95% CI 1.1-8.3, p = 0.03) and in individuals younger than 10 years of age (OR 5.2, 95% CI 1.8-14, p = 0.001). Functional constipation was observed in 50% of subjects. It was detected in 95.65% of the individuals with LUTS and 32.78% without LUTS (OR 45.1, 95% CI 5.66-301, p = 0.001). The symptom listed in question 8 ("push to pee") was the most specific indicator. When present, this symptom indicated a higher probability of LUTS (LR+ = 6.3), while the symptom listed in question 4 ("push for bowel movements to come out") showed high sensitivity and, when absent, indicated a lower probability of LUTS (LR- = 0.1). CONCLUSIONS: LUTS was more prevalent in young males with DS and appeared to improve with age. Functional constipation was strongly associated with LUTS. These findings will contribute to raising the awareness of professionals involved in the follow-up of individuals with DS regarding the clinical manifestations and the need for a standardized investigation of LUTS.

Transcutaneous parasacral electrical neural stimulation in children with primary monosymptomatic enuresis: a prospective randomized clinical trial.

PURPOSE: Parasacral transcutaneous electrical neural stimulation is widely used to treat hyperactive bladder in children and adults. Its use in nonmonosymptomatic enuresis has demonstrated improvement in number of dry nights. We assessed the effectiveness of parasacral transcutaneous electrical neural stimulation in the treatment of monosymptomatic primary enuresis. MATERIALS AND METHODS: This prospective randomized clinical trial included 29 girls and 16 boys older than 6 years with primary monosymptomatic enuresis. Children were randomly divided into 2 groups consisting of controls, who were treated with behavioral therapy, and an experimental group, who were treated with behavioral therapy plus 10 sessions of parasacral transcutaneous electrical neural stimulation. Neural stimulation was performed with the electrodes placed in the sacral region (S2/S3). Sessions always followed the same pattern, with duration of 20 minutes, frequency of 10 Hz, a generated pulse of 700 µs and intensity determined by the sensitivity threshold of the child. Sessions were done 3 times weekly on alternate days. Patients in both groups were followed at 2-week intervals for the first month and then monthly for 6 consecutive months. RESULTS: Rate of wet nights was 77% in controls and 78.3% in the experimental group at onset of treatment (p = 0.82), and 49.5% and 31.2%, respectively, at the end of treatment (p = 0.02). Analyzing the average rate of improvement, there was a significantly greater increase in dry nights in the group undergoing neural stimulation (61.8%) compared to controls (37.3%, p = 0.0038). At the end of treatment percent improvement in children undergoing electrical stimulation had no relation to gender (p = 0.391) or age (p = 0.911). CONCLUSIONS: Treatment of primary monosymptomatic enuresis with 10 sessions of parasacral transcutaneous electrical neural stimulation plus behavioral therapy proved to be effective. However, no patient had complete resolution of symptoms.

Structural study of prepuce in hypospadias--does topical treatment with testosterone produce alterations in prepuce vascularization?

PURPOSE: Androgen stimulation before hypospadias surgery has resulted in increased penile size, fewer complications and improved cosmesis, and suggests increased neovascularization. To our knowledge the real effect on neovascularization remains to be proved. We studied the histological effects of testosterone on neovascularization. MATERIALS AND METHODS: A total of 26 boys with hypospadias were randomly allocated to 2 groups before surgical correction. Group 1 did not receive any treatment and group 2 received 1% testosterone propionate ointment twice daily for 30 days before surgery. During the surgical procedure a fragment of prepuce was excised and prepared for histological evaluation. The number and volume density of blood vessels were determined by labeling for von Willebrand's factor. Blood vessel quantification as volume density was done using a video microscopy system with a superimposed cycloid arch test system. RESULTS: The groups were similar in age and hypospadias classification. Testosterone treated prepuces (group 2) had an increased absolute number of blood vessels (mean ± SD 8.5 ± 1.3 vs 4.8 ± 1.8 vessels per field) and increased blood vessel volume density (mean 50.5% ± 7.8% vs 24.8% ± 8.6% vessels per point) (each p <0.001) compared to those in untreated patients (group 1). CONCLUSIONS: The use of 1% testosterone propionate ointment before hypospadias surgery produces neovascularization in absolute numbers and in volume density.

[Acute abdomen: spontaneous bladder rupture as an important differential diagnosis]. / Abdome agudo: ruptura espontânea de bexiga como um importante diagnóstico diferencial.

A case of spontaneous perforation of the bladder in a diabetic female patient is reported. It is a rare clinical condition, that should be suspected in patients with a past history of radiotherapy to the pelvis, enterocystoplasty and those suspected of having a tumor in the bladder. A general surgeon should be aware of this possibility in the differential diagnosis of an acute abdomen.

Bladder augmentation for the treatment of chronic tuberculous cystitis. Clinical and urodynamic evaluation of 25 patients after long term follow-up.

AIMS: Clinical and urodynamic evaluation of the late outcome of 25 patients with chronic tuberculous cystitis who underwent bladder augmentation. PATIENTS AND METHODS: Twenty men and five women with median age of 40 years were evaluated. The tubularized ileocecal segment was used in 8 cases, the detubularized sigmoid in 13, and the tubularized sigmoid in 4. Patients underwent a postoperative clinical and urodynamic evaluation. Miccional diurnal frequency of more than 2 hr together with patient satisfaction as assessed by the quality of life question of the ICSmaleSF questionnaire was considered a good result. RESULTS: The average postoperative follow-up was of 11.1 +/- 9.1 (1 to 36) years. A good result was seen in 80% of the patients. Bad results occurred statistically in the cases using tubularized sigmoid and in patients with prostatitis. Patients with good results showed augmented bladders with normal sensation (P = 0.03) and greater capacity (P < 0.01) and compliance (P < 0.01) than did those with bad results. There was no statistically significant difference in the frequency of involuntary contractions (P = 0.27) but in the good result patients, the contractions started with greater bladder filling volume (P = 0.02). CONCLUSIONS: The sigmoid should be detubularized but the ileocecal segment may be used in its original tubularized form to augment the bladder with chronic tuberculous cystitis. Augmented bladder with capacity of more than 250 ml, good compliance, and normal sensation are necessary for diurnal frequency of more than 2 hr. The presence of involuntary contractions does not lead to a decrease in the diurnal frequency.

Bilateral giant renal angiomyolipoma associated with hepatic lipoma in a patient with tuberous sclerosis.

OBJECTIVE: To report a case of bilateral giant renal angiomyolipoma associated with tuberous sclerosis, with successful treatment, and to review the literature concerning angiomyolipoma treatment. CASE REPORT: Patient with tuberous sclerosis and angiomyolipoma diagnosed by ultrasonography during her pregnancy. At that time, the angiomyolipoma on the right side was 9 cm in diameter. Conservative management was selected during her pregnancy. The patient returned 7 years later, with a 24.7 x 19.2 x 10.7 cm tumor on the right side and another of 13 x 11.5 x 6.5 cm on the left side, in addition to multiple small angiomyolipomas. A nephron-sparing surgery with tumoral enucleation was performed on the right side, and after 3 months, the tumor on the left side was removed. Renal function in the post-operative period was preserved, and contrast medium progression was uniform and adequate in both kidneys. CONCLUSION: We conclude that an angiomyolipoma larger than 4 cm should be removed surgically, since they have a greater growth rate and pose a risk of hemorrhage. Resection of smaller tumors is safe and has decreased morbidity. Tumoral enucleation is an effective treatment method that preserves kidney function.
