Megaureter: Natural course

Series of imaging studies that demonstrate spontaneous resolution of a left megaureter without surgical intervention.

The imaging studies are IVPs as a neonate (panel A) and at 10-year follow-up (panel C) and a diuretic renogram at 2-year follow-up (panel B). The second image of the renogram shows a delay in washout. The diuretic renogram image is taken from the back to the front of the patient, reserving the position of the left and right kidney and ureter from the IVP images, which are taken from front to back.
