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

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

- The association between current micturition habits and previous urinary tract infection was analysed among 3553 school entrants aged 7 years by means of a questionnaire. A high incidence of urinary infection, confirmed by urine culture, was found (145 (8.4%) in the 1719 girls and 32 (1.7%) in the 1834 boys). There was a significant association between current symptoms that were suggestive of disturbed bladder function and previous urinary tract infection, but only among girls who were over 3 years of age at the time the first episode was diagnosed.

- OBJECTIVE: To study the epidemiology of micturition disturbances in teenagers. SUBJECTS AND METHODS: A subsample of 1034 teenagers previously evaluated at age 7 years was reinvestigated 10 years later. A postal questionnaire was used and a response rate of 71% (736) obtained. Those who reported bladder symptoms were contacted by telephone for a detailed history concerning imperative urge, daytime incontinence, emptying difficulties and bedwetting. RESULTS: There was a general decrease in the frequency and intensity of symptoms from 7 to 17 years of age. At age 17 at least one symptom was reported by 5.9% of the girls and 0.9% of the boys. Overall the symptoms were regarded as mild or moderate. CONCLUSION: At age 17 years, micturition disturbances were reported infrequently and few subjects wanted medical help.

- The prevalence of incontinence in children has been extensively studied, but knowledge of other bladder symptoms is lacking in a healthy child population. The micturition habits of 3556 7-year-old school entrants were surveyed by a questionnaire supplemented by telephone interviews. One or more symptoms of a disturbed bladder function was reported in 26%, but most of these had moderate urgency as a sign of incomplete voluntary bladder control. Isolated bedwetting occurred in 2.8% of the girls and 7.0% of the boys, whereas nocturnal incontinence combined with daytime wetting was equally common in both sexes, 2.3% and 2.0% respectively. Diurnal incontinence was reported in 6.0% of the girls and 3.8% of the boys and was usually combined with other symptoms. The frequency of micturition in children without symptoms of bladder disturbance and with no previous urinary tract infection was 3-7 times per day.

- PURPOSE: We compared reflux status in children with dilating vesicoureteral reflux treated in 3 groups, including low dose antibiotic prophylaxis, endoscopic therapy and a surveillance group on antibiotic treatment only for febrile urinary tract infection. MATERIALS AND METHODS: A total of 203 children 1 to younger than 2 years with grade III-IV reflux were recruited into this open, randomized, controlled trial. Endoscopic treatment was done with dextranomer/hyaluronic acid copolymer. The main end point was reflux status after 2 years. Data were analyzed by the intent to treat principle. RESULTS: Reflux status improved in all 3 treatment arms. Of patients in the prophylaxis, endoscopic and surveillance groups 39%, 71% and 47%, respectively, had reflux resolution or downgrading to grade I-II after 2 years. This was significantly more common in the endoscopic than in the prophylaxis and surveillance groups (p = 0.0002 and 0.0030, respectively). After 1 or 2 injections 86% of patients in the endoscopic group had no or grade I-II reflux but recurrent dilating reflux was seen in 20% after 2 years. CONCLUSIONS: Endoscopic treatment resulted in dilating reflux resolution or downgrading in most treated children. After 2 years endoscopic treatment results were significantly better than the spontaneous resolution rate or downgrading in the prophylaxis and surveillance groups. However, of concern is the common reappearance of dilating reflux after 2 years.

- Background Several publications have reported the coexistence of vesicoureteral reflux (VUR) and bladder dysfunction in children. Whether this dysfunction remains in the longer term is not yet known. Objective This study revisited children who participated in the Swedish Reflux Trial (SRT) with the primary aim of evaluating whether bladder and bowel dysfunction (BBD) in these patients persisted until adolescence. The secondary aim was to evaluate two BBD subgroups, and relations to recurrent urinary tract infections (UTI). Study design Of the 161 eligible children at SRT study -end, 73 children participated. Their bladder function was evaluated longitudinally using a validated BBD questionnaire with symptom score (cut -off >7) and uroflowmetry, at five (T2) and ten years (T3) after study -end. T1 was the SRT study -end. Besides BBD, the sub-diagnoses overactive bladder (OAB) and dysfunctional voiding symptoms (DVS) were calculated from symptom scores. Results BBD was diagnosed in 37% of children at mean age 3.7 years, which decreased with age to 23% of adolescents (mean age 15.7). DVS and OAB subgroups were equally common at T1, but only DVS was identified at the last follow-up (T3) (p = 0.0008). Recurrent UTIs were seen in 17% at T3 and were more common in patients with BBD (p = 0.038). The gender distribution of BBD also changed, from being equally common at the end of the SRT to affecting mainly adolescent girls at the last follow-up (p = 0.022). Information was available regarding VUR status after repeat VCUGs during follow-up in 22 patients, 12 of them after endoscopic treatment. An improvement in VUR grade was found in the 22, but during follow-up numbers with BBD or UTI did not differ between treated and non-treated groups. Discussion The prevalence of BBD decreased from 37% at 3-4 years of age to 23% in adolescence, when it was almost exclusively seen in girls. BBD and the subgroup DVS were associated with UTI. Even if epidemiological studies have established a predisposition to bladder symptoms and UTI in girls, little is known about bladder function in adolescents with a history of VUR during the first years of life. One limitation of the study was the number of patients participating. Also, the number of patients with kidney damage was more common in the cohort. Conclusion In this longitudinal follow-up of BBD in children with VUR, the number of children with BBD decreased with age. In adolescence, both BBD and recurrent UTIs mainly affected girls.

- PURPOSE: We investigated the prevalence and types of lower urinary tract dysfunction in children with vesicoureteral reflux grades III and IV, and related improved dilating reflux, renal damage and recurrent urinary tract infection to dysfunction. MATERIALS AND METHODS: A total of 203 children between ages 1 to less than 2 years with reflux grades III and IV were recruited into this open, randomized, controlled, multicenter study. Voiding cystourethrography and dimercapto-succinic acid scintigraphy were done at study entry and 2-year followup. Lower urinary tract function was investigated by noninvasive methods, at study entry with 4-hour voiding observation in 148 patients and at 2 years by structured questionnaire and post-void residual flow measurement in 161. RESULTS: At study entry 20% of patients had lower urinary tract dysfunction, characterized by high bladder capacity and increased post-void residual urine. At 2 years there was dysfunction in 34% of patients. Subdivision into groups characteristic of children after toilet training revealed that 9% had isolated overactive bladder and 24% had voiding phase dysfunction. There was a negative correlation between dysfunction at 2 years and improved dilating reflux (p = 0.002). Renal damage at study entry and followup was associated with lower urinary tract dysfunction at 2 years (p = 0.001). Recurrent urinary tract infections were seen in 33% of children with and in 20% without dysfunction (p = 0.084). CONCLUSIONS: After toilet training a third of these children with dilating reflux had lower urinary tract dysfunction, mainly voiding phase problems. Dysfunction was associated with persistent reflux and renal damage while dysfunction at study entry did not predict the 2-year outcome.

- PURPOSE: We studied the spontaneous resolution rate in a group of infants with high grade vesicoureteral reflux (VUR). The influence of gender, prenatal or postnatal diagnosis, recurrent urinary tract infections (UTIs) and bladder dysfunction on the resolution rate was also evaluated. MATERIALS AND METHODS: This prospective study comprised 115 infants (80 boys and 35 girls) with high grade VUR (grades III to V). Bilateral reflux was seen in 70% of cases. The majority of patients (71%) were diagnosed after UTI during infancy and only 26% were prenatally diagnosed. Median age at diagnosis was 2.7 months. Patients were followed according to a program of repeat video cystometry and noninvasive 4-hour voiding observations. Median followup was 39 months. RESULTS: The overall spontaneous resolution rate to grade II or less for all grades was 39% with no difference between boys and girls. However, when comparing the more severe grades IV and V, we found a significantly higher resolution rate in boys during the infant year. No difference in VUR disappearance could be detected when comparing the groups according to presentation, prenatal ultrasound or pyelonephritis. Breakthrough UTIs were seen in 47% of cases despite antibacterial prophylaxis and they significantly correlated with VUR nonresolution. Bladder dysfunction was found in 37% of patients and it also significantly correlated with nonresolution. CONCLUSIONS: The spontaneous resolution rate for high grade (grades IV and V) congenital VUR was high in boys during the infant year (29%), whereas in girls and boys after the infant year the resolution rate was 9% yearly during followup. Negative prognostic factors for resolution were recurrent UTIs and bladder dysfunction.
