A case of right ureteric damage in a 7-year-old boy who underwent appendicectomy is described. Ultrasound, magnetic resonance urography, nephrostogram, and retrograde ureterogram were helpful in defining the nature and extent of the lesion. He underwent staged procedures of percutaneous nephrostomy, elective resection and reconstruction of midureteral segment, and subsequent removal of double J stent and made a smooth recovery. Ureteric injuries, although rare, have serious consequences. A high index of suspicion is essential for diagnosis.
