Surgical image (above) shows the decompressed distal right ureter (with the black loop around it) emerging from behind the inferior vena cava in the center of the image. The dilated proximal right ureter can be see just to the right of the inferior vena cava at the top of the image. Post operative surgical image (below) shows the red vessel loops around the now decompressed proximal right ureter which has been transected and reanastomosed anterior to the inferior vena cava in the center of the image.
