CEUS nephrostogram. Images obtained of the entire ureter and bladder following ultrasound contrast administered through an in-dwelling nephrostomy confirms patency of the collecting system with contrast opacifying the (A) renal calyces, (B) ureter and (C) bladder, which contains a urinary catheter (white arrow). (D) Conventional fluoroscopic nephrostogram confirms free drainage along the collecting system and into the bladder (arrows)
