Obstructing 5 mm stone at the left VUJ with upstream ureteric dilatation and mild left PC system dilatation.

The ureters descend on the anteromedial aspect of the psoas muscles into the pelvis, and then anterior to the internal iliac vessels until the ischial spine where they run anteromedially for a short distance before entering the urinary bladder.
