Fluoroscopy - Antegrade pyelogram / nephrostogram

Antegrade pyelography / nephrostogram for evaluation of an ileal interpostion between the right renal pelvis and the bladder.
As water soluble contrast fills the collecting system it enters the bowel loop and gradually proceeds antegrade toward the bladder.
There had been a right ureteral stent which had migrated entirely into the bladder, as can be seen on the scout image.
