The simultaneous visualization of the same region in conventional B mode and contrast-enhanced mode allowed the identification of ureters. Left side: B mode ultrasound visualization of renal artery (a) vein (v) within the lymphocele (L) and bladder (B). Right side: contrast-enhanced ultrasound visualization of the same region showing the bladder (B) and the ureter (arrows) filled by contrast agent.
