title: Calcification in a Deflux bleb thought to be a ureteral calculus in a child.
abstract: A child admitted for abdominal pain was evaluated with an abdominal computed tomography scan. Calcification was noted at the ureterovesical junction. The child had undergone successful bilateral Deflux injection 3 years earlier. No hydronephrosis was noted and an intravenous pyelogram was normal. Ureteroscopy revealed no intraluminal stones, and a follow-up scan showed the lesion to be still present and unchanged. This case illustrates that calcifications within a Deflux bleb can be mistaken for a ureteral calculus, and the entire clinical picture should be kept in mind when evaluating a patient with abdominal pain. Due to the widespread use of Deflux to treat vesicoureteral reflux, this phenomenon may be seen more frequently as this population ages.
