The management of vesicoureteral reflux (VUR) is one of the most challenging issues not only for pediatric urologists but also for pediatric nephrologists and all other related subspecialties. Urinary tract infections (UTI), pyelonephritis and renal scarring which may lead to deterioration in renal function are the common complications in a child presenting with VUR. Due to the patient heterogeneity and varying management options, patient selection for each treatment modality remains as a controversial issue. The different bio-statistical models have been used in order to disclose the factors affecting success of different management modalities and represent the incidence of possible complications. Bio-statistical models are useful to define variables which may help predict the outcome of disease during the different managements. Artificial neural networks (ANN) and regression models are popular methods employed to predict the outcome of urological abnormalities. Statistical models and ANNs provide an estimation of the probability of outcome that is of utmost importance in clinical decision. This study addresses both bio-statistical methods and ANNs employed to predict the outcome of VUR management and their clinical applications. To reach the best fit model that predicts the VUR outcome in a child, widespread knowledge regarding available bio-statistical methods is needed.
