Pyelo-ureteral junction syndrome is the most common urological abnormality in children. Functional MRI has been evaluated several times, and had shown good correlation with scintigraphy, but tends to over estimate results. Moreover, those studies included a small number of cases. Its sensitivity to detect crossing polar vessel is limited. We aimed to evaluate, in patients between 0 and 1 year old, the correlation between MRI and scintigraphy differential renal function. Our secondary objectives are : evaluation of MRI performances to detect polar vessel ; comparison of surgery times depending of MRI only realisation or MRI and scintigraphy realisation.
