Nine hundred and seven patients were grouped with follow-up according to the diagnostic method used for detecting hydronephrosis; the first group included the 563 patients whose diagnosis was made by excretory urography
, and the second group included the 344 patients who were diagnosed by renal ultrasound.
Digital fluoroscopic excretory urography
, digital fluoroscopic urethrography, helical computed tomography, and cystoscopy in 24 dogs with suspected ureteral ectopia.
Radiologic investigation of renal colic: unenhanced CT compared with excretory urography
Material and Methods: This was a randomized control trial of 588 patients undergoing excretory urography
at a tertiary care hospital.
For the most part, excretory urography
and barium gastrointestinal studies are rarely, if ever, utilized.
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.
Evaluation of the renal outline by excretory urography
provides assessment of renal function.
Imaging findings of urinary tuberculosis on excretory urography
and computerized tomography.
, sonography, and abdominal radiography were being used prior to the establishment of role of CT for the evaluation of ureterolithiasis5.
Several imaging techniques used in the evaluation and differentiation of pelvic cystic masses include excretory urography
, ultrasound, CT and magnetic resonance imaging.
