Adverse reactions following intravenous contrast media administration are uncommon. In a study of 302,083 urographic examinations, Shehadi 1 established an overall incidence of adverse reactions to be at or slightly below 5%. Based on the clinical status of the patients and the need for treatment these adverse reactions are graded into minor, intermediate, severe and death. Minor reactions such...

We read with interest the article by Xie et al. (1) in a previous issue of Nephro-Urology Monthly (October 2011), regarding the comparison between intravenous urography and computed tomography urography in diagnosing ureteropelvic junction obstruction. As previously described, pathological lesions at the ureteropelvic junction are classified into intrinsic and extrinsic abnormalities. In the ca...

Introduction: Computed Tomography (CT) urography is more accurate in detection of renal masses, urinary tract tumors, inflammatory lesion, calculi and other causes obstruction compared with intravenous urography. The standard single bolus MDCT Urography protocol comprises three to four phases, consists non-contrast, corticomedullary, nephrographic excretory phases. A major disadvantage a high r...

we report a patient who was admitted to the department of medicine with palpitation, dyspnea and left flank pain, chest x-ray revealed a mass in the left lung. the lesion was evaluated as a pulmonary tumor, with a high suspicion of malignancy. intravenous urography, sonography, and ctscanning revealed a thoracic kidney at the location previously thought to be a lung mass. this is the first repo...

We present a case of renal stone associated with bilateral pelvic diverticula. The initial diagnosis by ultrasonography and plain abdomen radiography (KUB) was urolithiasis with a 15-mm calculus in the right renal pelvis. The patient was referred for extracorporeal shock wave lithotripsy, but no stone fragments were yielded. So, further evaluations were performed by using repeated ultrasonograp...

Between 1988 and 1999, renal sonography and intravenous urography were performed to detect renal malformations in 54 patients with Turner's syndrome (TS). The mean age of these patients at diagnosis of TS was 9.2 +/- 4.6 years. Renal malformations were detected in 21 patients by intravenous urography and there was no significant difference in the frequency of renal malformations among different...
