Color Doppler Ultrasonography in the Diagnosis of Vascular Abnormalities Associated with Ureteropelvic Junction Obstruction

Abstract

Purpose:

To determine if color Doppler ultrasonography is able to identify vascular abnormalities linked to ureteropelvic junction (UPJ) obstruction.

Patients and 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%.

Conclusion:

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