Case report demonstrates spontaneous retrograde migration of a ureteral stone in a child with obstructive megaureter, highlighting unusual calculus dynamics in dilated urinary tracts.
Key Points

Clinical assessment and serial radiological imaging of a 9-year-old boy presenting with left flank pain and haematuria.
Surgical intervention to evaluate distal ureteric pathology and verify stone location.
