Contemporary Diagnosis of Retrocaval Ureter

Abstract

Purpose:

We describe a noninvasive radiologic evaluation of a retrocaval ureter using currently available technology.

Materials and Methods:

Three-dimensional volume-rendered CT and diuretic renography were performed for evaluation of a possible retrocaval ureter.

Results:

The 3D CT scan definitively diagnosed the retrocaval ureter, while diuretic renography showed no evidence of clinically significant obstruction. No invasive procedures were required.

Conclusion:

A 3D volume-rendered CT scan in the excretory phase combined with diuretic renography is the radiologic evaluation of choice for patients with a suspected retrocaval ureter, as it is noninvasive yet highly accurate in its anatomic delineation.
