Ureteral Dilatation with No Apparent Cause on Intravenous Urography: Normal or Abnormal? A Pilot Study
Table 2
Causes of ureteral dilatation on CT Urography (
).
| | Number | Right ureter | Left ureter |
| | Case | Ureteral calculus | Normal ureter | | Case | Extrinsic vascular impression (internal iliac artery); ureteritis | Normal ureter | | Case | Not assessed | Extrinsic vascular impression (common iliac artery); ureteritis | | Case | Extrinsic vascular impression (common iliac artery) | Normal ureter | | Case | Extrinsic vascular impression (bifurcation of common iliac artery) | Normal ureter | | Case | Ureteral stricture at external iliac artery origin level | Normal ureter | | Case | Ureteral stricture at lumbosacral junction level | Normal ureter | | Case | Extrinsic vascular impression (common iliac artery) | Ureteritis | | Case | Extrinsic vascular impression (common iliac artery) | Normal ureter |
|
|
Case : right ureter was not assessed on CT Urography as it was not visible on Intravenous Urography and hence not dilated.
