4-year-old girl with right sided urinary tract dilatation (P3) (hydroureter and hydronephrosis) due to primary megaureter. MCUG was unremarkable. She underwent IVP elsewhere (a) and confirms presence of hydroureter and hydronephrosis in addition to hold up of the contrast at the distal ureteric end. b Dynamic MRU at our institution confirms the same findings with symmetric nephrograms and signal intensity versus time curves (c) with symmetric calyceal transit time (99 s) indicating compensated hydronephrotic system
