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


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.


CONCLUSIONS
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.
