Predictive value of cortical transit time on MAG3 for surgery in antenatally detected unilateral hydronephrosis caused by ureteropelvic junction stenosis

CTT on an initial MAG3 scan may be a useful predictor of the need for surgery in children with antenatally detected unilateral hydronephrosis caused by UPJ stenosis.115Summary Figure.
