Excretory Urography

Urography, Excretory

 

(also called descending urography), roentgen examination of the kidneys and urinary tract after injection of an X-ray contrast medium such as methiodal sodium, which is excreted by the kidneys. The method makes it possible to determine the condition of the kidneys and urinary tract and is used to detect nephrolithiasis, renal tuberculosis, and other diseases.

Three angles on the pretreatment excretory urography were measured; the inner angle between the axis of the lower pole infundibular and ureteropelvic axis (angle 1), lower pole infundibular axis and main axis of pelvis-ureteropelvic junction point (angle 2), and lower pole infundibular axis and perpendicular line (angle 3).
Although these studies have used excretory urography (IVP) as the reference standard, noncontrast helical computed tomography (CT) appears to be a superior reference standard.[1,2] The authors of this study examined the accuracy of hematuria testing compared with a reference standard of helical CT and attempted to differentiate between dipstick screening and different thresholds of microscopic hematuria.
