Color Doppler ultrasonography in the diagnosis of vascular abnormalities associated with ureteropelvic junction obstruction.
OBJECTIVE
To determine if color Doppler ultrasonography is able to identify vascular abnormalities linked to ureteropelvic junction (UPJ) obstruction.


METHODS
We used color Doppler scanning in 21 patients to determine whether there were aberrant vessels.


RESULTS
The study detected 11 aberrant vessels, resulting in 10 true positives and 9 true negatives. Thus, the overall diagnostic accuracy was 90.4%.


CONCLUSIONS
Color Doppler ultrasonography is reliable in the preoperative diagnosis of aberrant vessels associated with UPJ obstruction.
