Purpose: To evaluate the efficacy of standard and biofeedback bladder control training (BCT) on the resolution of dysfunctional elimination syndrome (primary outcome), and on the reduction of urinary tract infections (UTI) and the use of medications such as antibacterial prophylaxis and/or anticholinergic/alpha-blockers (secondary outcome) in girls older than aged least 5 years.Materials and Methods:72 girls,median age of 8 years (interquartile range, IQR 7-10) were subjected to standard BCT (cognitive, behavioural and constipation treatment)and 12 one-hour sessions of animated biofeedback using interactivecomputer games within 8 weeks.Fifty patients were reevaluated after median 11 (IQR, 6-17) months. Effectiveness of BCT was determined by reduction of dysfunctional voiding score (DVS), daytime urinary incontinence (DUI),constipation, UTI,nocturnal enuresis (NE), post void residual (PVR), and improvements in bladder capacity and uroflow/EMG patterns. Results: BCT resulted in significant normalization of DUI, NE, constipation, bladder capacity, uroflow/EMG, while decrease of PVR didn't reach statistical significance. In addition, the incidence of UTI, antibacterial prophylaxis and medical urotherapy significantly decreased. There were no significant differences in DVS, DUI, NE, bladder capacity and voiding pattern at the end of the BCT and at the time of reevaluation. The success on BCT was supported by parenteral perception of the treatment response in 63.9% and full response in additional 15.3% of the patients. Conclusion: Combination of standard and biofeedback BCT improved dysfunctional elimination syndrome and decreased UTI with discontinuation of antibacterial prophylaxis and/or anticholinergic/alpha-blockers in the majority of thepatients. Better training results are expected in patients with higher bladder wall thickness as well as in those with vesicoureteral reflux, while presence of nocturnal enuresis may be a negative predictor of the training effect.

Background: Acute kidney injury (AKI) is a common postoperative complication following cardiopulmonary bypass (CPB) surgery. New biomarkers to identify patients with early AKI (before increases in serum creatinine) are needed to facilitate appropriate treatment. This study aimed to test the role of urinary liver fatty-acid-binding protein (L-FABP) as an early biomarker for AKI in children undergoing CPB surgery. Methods: This is a case-control study of children undergoing CPB. AKI was defined as 50 % increase in serum creatinine at 48 h after surgery. For each patient, five serum and urine samples were obtained corresponding to time 0 h (presurgery) and 2, 6, 24, and 48 h after surgery. Results: Twenty-seven patients, median age 360 days, were enrolled. AKI developed in 11 patients (41 %); three needed renal replacement therapy (peritoneal dialysis); there were two deaths. There were significant differences between patients with and without AKI in L-FABP levels at 2, 6, and 48 h after surgery, length of hospital stay, and CPB time; there were no differences in gender, patient age, and body weight. L-FABP was normalized to urinary creatinine concentration at all time points, with area under the receiver operator curve (AUC ROC) 0.867 at 2 and 6 h postoperatively. Correlation coefficient between L-FABP and length of hospital stay after surgery was statistically significant (r = 0.722, p value = 0.000). Conclusions: Our results suggest that urinary L-FABP can be used to diagnose AKI earlier than rise in serum creatinine in children undergoing CPB. © 2013 IPNA.
