An Adult Case of Severe Asymptomatic Bilateral Ureteropelvic Junction Obstruction

Figure 1

(a) The nephrogram phase of the contrast enhanced CT scan shows severe bilateral dilatation of the renal calyceal system and renal pelvises (). (b) The CT scan shows a severely dilated right kidney pelvis () with a nonobstructing stone in it (arrow). (c) The urogram phase of the contrast enhanced CT scan shows a severely dilated contrast filled right renal pelvis () and a normal caliber right renal ureter separated by ureteropelvic junction stricture (arrow). (d) The coronal view of the nephrogram phase of the contrast enhanced CT scan shows bilateral dilatation of renal pelvises (), more severe in the right side, and a nonobstructing stone in the right renal pelvic (arrow).
