Figure 2: (a) Ultrasound image of the right kidney (along its long axis) showing dilated pelvicalyceal system (SFU Grade 3) with abrupt tapering at the level of pelvi-ureteric junction (arrow). (b) Transverse image at the level of lower pole showing that the upper/mid-ureter is not dilated. (c) Transverse ultrasonography image at the level of bladder trigone showing normal insertion of ureters at vesicoureteric junction (arrow) and there is no dilatation of distal ureters
