Figure 2 Ultrasound images of the kidneys and bladder. (A) Right hydronephrosis with dilated major calyces (c) and minor calyces (white arrows) and dilatation of the proximal ureter (black arrows). (B) The left kidney with a stone (white arrow). (C) The atrophic left kidney. The parenchyma is thin (white arrowheads) as compared with the right side. Echogenicity of the left kidney is increased as compared with the adjacent spleen (S). (D) A sagittal view of the bladder (b and black arrowheads) shows a stone (dashed white arrow) at the right vesicoureteral junction and a dilated distal ureter (black arrows). (E) For comparison, a normal ultrasound image of the right kidney. The renal parenchyma (black arrows) has slightly decreased echogenicity compared with the adjacent liver (L). A nondilated collecting system usually cannot be differentiated in echogenic renal sinus (RS).

Figure 3 Computed tomography (CT) of the abdomen without contrast. (A, B) Axial images show right hydronephrosis and hydroureter (white arrow) and right stone at the ureterovesical junction (black arrow). The left kidney is atrophic and contains a stone (black dashed arrow). (D, E) Coronal reconstructions of the same noncontrasted computed tomographic scan also show (D) right hydronephrosis and (E) hydroureter (white arrows). The left kidney is atrophic (white arrow heads). (C) Axial and (F) coronal images of the right kidney of a different patient show a normal collecting system (curved white arrows) and normal hilar vessels (white dashed arrows).
