Color Doppler ultrasonography in the diagnosis of vascular abnormalities associated with ureteropelvic junction obstruction

J Endourol. 2003 Nov;17(9):745-50. doi: 10.1089/089277903770802290.

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.
