RESUMEN
BACKGROUND: Monosymptomatic enuresis (MNE) results from a pathogenic triad that may include lack of vasopressin secretion during sleep, reduced functional bladder capacity and inability to wake up during sleep. The treatment of MNE can be performed through behavioral therapy, use of alarms or medications such as desmopressin and imipramine. OBJECTIVE: To compare the effectiveness of different treatments of MNE. STUDY DESIGN: Prospective and randomized study comparing different intervention and a control group (receiving only behavior therapy) for MNE. INCLUSION CRITERIA: age between 5 and 16 years old, with MNE, evaluated at the pediatric urology outpatient clinic of Hospital Infantil Menino Jesus. At first visit children were submitted to behavior therapy (urotherapy) for 3 months, children were subsequently characterized according to the ICCS as non-responders, partial responders, or full responders. Those partial responders or non-responders received a patient ID and were randomized to four groups: Alarm Group (G1), Desmopressin Group - DDAVP (G2), Imipramine Group (G3) and Control (G4). All groups were monitored monthly, for a period of 6 months. After 6 months, the children were reevaluated for MNE. RESULTS: 93 patients were enrolled. Mean age was 10.96 years with a standard deviation of 2.28 years, 59,1% were male. All groups had improvement in the number of dry nights (Table). Taking in account success the population full responders and partial responders: Alarm Group (G1) achieve success in 100% of cases, Desmopressin Group - DDAVP (G2) in 63.6% of cases, Imipramine Group (G3) in 73.7% of cases (Table 3). No drugs side effects were observed in both groups (G2 and G3), there was no dropout in patients who used alarms. DISCUSSION: Our data suggests that the use of alarms is the most effective treatment of ENM with superior results when compared to imipramine and DDAVP. The small number of participants is a weakness of the study, as well as the lack of a voiding diary at the end of the study. CONCLUSION: All therapeutics options utilized in the treatment of MNE are safe, effective and has a low rate of abandonment.

AIMS: Preservation of renal function in children with congenital neurogenic bladder is an important goal of treatment for the disease. This study analyzed the evolution of renal function in patients with congenital neurogenic bladder. METHODS: We reviewed the records of 58 pediatric patients with respect to the following attributes: gender, age, etiology of neurogenic bladder, reason for referral, medical/surgical management, episodes of treated urinary tract infections, urodynamics, DMSA scintigraphy, weight, height, blood pressure, glomerular filtration rate, microalbuminuria and metabolic acidosis. Statistical analysis was performed, adopting the 5% significance level. RESULTS: The mean age at presentation was 4.2 ± 3.5 years. Myelomeningocele was the most frequent etiology (71.4%). Recurrent urinary tract infection was the reason for referral in 82.8% of the patients. Recurrent urinary tract infections were diagnosed in 84.5% of the patients initially; 83.7% of those patients experienced improvement during follow-up. The initial mean glomerular filtration rate was 146.7 ± 70.1 mL/1.73 m²/min, and the final mean was 193.6 ± 93.6 mL/1.73 m²/min, p = 0.0004. Microalbuminuria was diagnosed in 54.1% of the patients initially and in 69% in the final evaluation. Metabolic acidosis was present in 19% of the patients initially and in 32.8% in the final assessment. CONCLUSIONS: Patient referral to a pediatric nephrologist was late. A reduction in the number of urinary tract infections was observed with adequate treatment, but microalbuminuria and metabolic acidosis occurred frequently despite adequate management.
